I have a project that does multi-touch...image moving, resizing etc. These images are loaded on the fly, so I don't know how many may load onto the canvas. The moving and resizing has all been worked out. However, I would like to put a label on each image. When I place the Image usercontrol nto a container and make a label, I lose all ability to resize, which is crucial.

Here is the Picture controls XAML:

<UserControl x:Class="DocumentHandlingTouch.Picture"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><Image Source="{Binding Path=ImagePath}" Stretch="Fill" Width="Auto" Height="Auto" RenderTransformOrigin="0.5, 0.5"><Image.RenderTransform><TransformGroup><RotateTransform Angle="{Binding Path=Angle}"></RotateTransform><ScaleTransform ScaleX="{Binding Path=ScaleX}" ScaleY="{Binding Path=ScaleY}"></ScaleTransform><TranslateTransform X="{Binding Path=X}" Y="{Binding Path=Y}"/></TransformGroup></Image.RenderTransform></Image></UserControl>

Here is some of the Picture controls class...the portion i use to set the image path:

  public partial class Picture : UserControl
    {

        public Picture()
        {
            InitializeComponent();
            DataContext = this;

        }

        public string ImagePath
        {
            get { return (string)GetValue(ImagePathProperty); }
            set { SetValue(ImagePathProperty, value); }
        }

        public string ImageName
        {
            get { return (string)GetValue(ImageNameProperty); }
            set { SetValue(ImageNameProperty, value); }
        }
        public static readonly DependencyProperty ImageNameProperty =
    DependencyProperty.Register("ImageName", typeof(string), typeof(Picture), new UIPropertyMetadata(""));

the complete code for what I'm doing can be found on OneDrive at DocumentHandling.

Again, I am not looking for any help in getting these images to move or resize, what I'm looking for is a way to get a label onto these images that still allows them to be moved or resized.

publicstaticList<string> Decollate(stringfileToDecollate,stringoutputPath)

  // iterate fixed documents and fixed pages, create new XPS files

  List<string> xpsDecFiles = newList<string>();

  using(XpsDocumentxpsSourceDocument = newXpsDocument(fileToDecollate,FileAccess.Read))

    FixedDocumentSequencefixedDocSeq = xpsSourceDocument.GetFixedDocumentSequence();

    intpageNumber = 0;

    foreach(DocumentReferencedocReferenceinfixedDocSeq.References)

      FixedDocumentsourceFixedDoc = docReference.GetDocument(false);

      foreach(PageContentpageinsourceFixedDoc.Pages)

        // prepare new fixed doc sequence

       FixedDocumentSequencenewFixedDocSeq = newFixedDocumentSequence();

       DocumentReferencenewDocReference = newDocumentReference();

       FixedDocumentnewFdoc = newFixedDocument();

       // copy the page

       PageContentnewPage =newPageContent();

       // tickle this method... presumably just to load the FixedPage data.

       FixedPagenewFixedPage = newPage.GetPageRoot(false);

       // Add page to fixed doc sequence.

       // Always do this last: add document reference to fixed doc sequence. 

       // create and save new XPS doc                   

       stringdecFileName =Path.Combine(outputPath,Path.GetFileNameWithoutExtension(fileToDecollate)+ "~"+ (pageNumber).ToString()+ FileExtensions.XPS);

       if(File.Exists(decFileName))File.Delete(decFileName);

       XpsDocumentnewXPSDoc = newXpsDocument(decFileName,FileAccess.ReadWrite);

       // testing.  thread IDs should be the same.

       //Debug.Assert(System.Windows.Threading.Dispatcher.CurrentDispatcher.Thread.ManagedThreadId == newFixedDocSeq.Dispatcher.Thread.ManagedThreadId);

       XpsDocument.CreateXpsDocumentWriter(newXPSDoc).Write(newFixedDocSeq);

       // add file to list

  returnxpsDecFiles;

I am using a binding proxy to bind top-level data from a viewmodel in a datagrid template column as shown below.

The issue I have is that while it works at runtime, it does not work within the IDE designer.

I can use a ContentControl however, I also use the binding proxy with a third party control which cannot access elements in a ContentControl so I would like to make the binding proxy work.

Can anyone help?

The following example uses a top-level string property named BrushProvider to simplify the illustration. The actual requirement is to use an object which will be passed to a multivalueconverter within the datatemplate

BindingProxy.cs - from this Blog

using System.Windows;

namespace BindingProxyIssue.Classes
{
	public class BindingProxy : Freezable
	{
		public static readonly DependencyProperty DataProperty = DependencyProperty.Register("Data", typeof (object), typeof (BindingProxy));

		protected override Freezable CreateInstanceCore()
		{
			return new BindingProxy();
		}

		public object Data
		{
			get { return GetValue(DataProperty); }
			set { SetValue(DataProperty, value); }
		}
	}
}

MyDataLine.cs

using System.Windows;

namespace BindingProxyIssue.Classes
{
	public class MyDataLine : DependencyObject
	{
		public static readonly DependencyProperty TextProperty = DependencyProperty.Register("Text", typeof(string), typeof(MyDataLine));
		public static readonly DependencyProperty NumberProperty = DependencyProperty.Register("Number", typeof(int), typeof(MyDataLine));

		public int Number
		{
			get { return (int)GetValue(NumberProperty); }
			set { SetValue(NumberProperty, value); }
		}
		public string Text
		{
			get { return (string)GetValue(TextProperty); }
			set { SetValue(TextProperty, value); }
		}
	}
}

    public class MyDataViewModel : DependencyObject
    {
        public static readonly DependencyProperty BrushProviderProperty = DependencyProperty.Register("BrushProvider",

            for(var n=0 ; n<5; n++)
                _dataLines.Add(new MyDataLine { Text = "This is Line level Text ", Number = n});
        }

        //This property would be an object - is set to a string to illustrate the issue
        public string BrushProvider
        {

Hi,

This might be a long shot, but Nuance support redirected me here.

A bit of context:

I'm trying to use Dragon Naturally Speaking with my WPF application.

They have a feature called "Full-Text Control" that allows you to correct, replace text etc... with voice commands.

Dragon comes with a toolbar that hovers at the top of the screen. Inside that bar, there's a Checkmark icon that turns green when the current focused RichTextBox supports "Full-Text Control"

This feature isn't working with WPF and I'm using a RichTextBox like I'm supposed to.

If i use WinForms, everything works fine.

Has anyone encountered this?

Can I implement something so my RichTextBox/application supports FTC?

How does Dragon evaluate if a RichTextBox/application supports FTC?

Regards,

Nicolas

I have a big problem. I want to prevent an opened drop-down menu to close when hovering another menu item. How can I achieve this? Thanks.

Our application uses WPF. One window includes tab control. Tab header Text is displayed as Black.

when select tab, we want the selected tab display different foreground for Tab Header text. For example, change the Foreground to "White".

We have create following style template for TabItem. In the <ControlTemplate.Trigger> section, when tab is selected, we try to set Foreground to "White". 

<ControlTemplate x:Key="TabItemControlTemplate01" TargetType="{x:Type TabItem}"><ControlTemplate.Resources><Storyboard x:Key="Storyboard1"/></ControlTemplate.Resources><Grid Height="80" MinWidth="125"><Border x:Name="Border" Margin="0,0,0,0"
				BorderBrush="{x:Null}" CornerRadius="0" BorderThickness="0" ><Border.Background><LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"><GradientStop Color="#FFDBEEFF" Offset="0.246"/><GradientStop Color="#FFA7CCED" Offset="1"/></LinearGradientBrush></Border.Background><ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
					HorizontalAlignment="Center"
					ContentSource="Header" Margin="2,2,2,2"
					RecognizesAccessKey="True"></ContentPresenter></Border><Rectangle x:Name="rectangle" HorizontalAlignment="Left" Height="4" Margin="0,76,0,0" Stroke="{x:Null}" VerticalAlignment="Top" Width="170" StrokeThickness="0" d:CopyToken="64b87611-7ebf-482c-b9f1-e10935bd6b33" Fill="{x:Null}"/><Rectangle x:Name="rectangle1" HorizontalAlignment="Left" Height="4" Margin="0,76,0,0" Stroke="{x:Null}" StrokeThickness="0" VerticalAlignment="Top" Width="170"><Rectangle.Fill><LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"><GradientStop Color="#FF5C84B0" Offset="0"/><GradientStop Color="#FFC7DFF9" Offset="1"/><GradientStop Color="#FF6E93BB" Offset="0.349"/><GradientStop Color="#FF7FA0C6" Offset="0.694"/></LinearGradientBrush></Rectangle.Fill></Rectangle><Rectangle x:Name="glow" HorizontalAlignment="Left" Height="76" Margin="0" Stroke="{x:Null}" StrokeThickness="0" VerticalAlignment="Top" Width="170" Fill="{x:Null}"/></Grid><ControlTemplate.Triggers><Trigger Property="TabItem.IsSelected" Value="True"><Setter Property="Panel.ZIndex" Value="100" /><Setter TargetName="Border" Property="Background" Value="{StaticResource ButtonSelecteddBackgroundFill}"/><Setter TargetName="Border" Property="BorderThickness" Value="0" /><!--<Setter Property="Foreground" Value="White" />--><Setter Property="Fill" TargetName="rectangle"><Setter.Value><LinearGradientBrush EndPoint="0.5,1" StartPoint="0.5,0"><GradientStop Color="White" Offset="0.112"/><GradientStop Color="#FFE0E0E0" Offset="0.155"/><GradientStop Color="Gainsboro" Offset="0.866"/><GradientStop Color="#FF767676" Offset="0.957"/></LinearGradientBrush></Setter.Value></Setter><Setter Property="Fill" TargetName="rectangle1" Value="{x:Null}"/><Setter Property="Width" TargetName="glow" Value="125"/><Setter Property="Margin" TargetName="glow" Value="0"/><Setter Property="Height" TargetName="glow" Value="76"/><Setter Property="Fill" TargetName="glow"><Setter.Value><RadialGradientBrush Center="0.5,1.001" GradientOrigin="0.5,1.001" RadiusY="0.618" RadiusX="0.618"><GradientStop Color="Transparent" Offset="1"/><GradientStop Color="#4CFFFFFF" Offset="0"/></RadialGradientBrush></Setter.Value></Setter></Trigger><Trigger Property="IsEnabled" Value="False"><Setter TargetName="Border" Property="Background" Value="DarkRed" /><Setter TargetName="Border" Property="BorderBrush" Value="Black" /><Setter Property="Foreground" Value="DarkGray" /></Trigger></ControlTemplate.Triggers></ControlTemplate>

we apply this TabItem template in following way:

<TabItem  x:Name="tabItemService" Template="{StaticResource TabItemControlTemplate01}"
           Style="{StaticResource TabItemControlStyle}" Width="{Binding TabHeaderWidth}"><TabItem.Header><DockPanel><Image Name="Developer" Height="55" Width="auto" Source="/Resources/Images/Info.png" DockPanel.Dock="Top"/><TextBlock Style="{StaticResource TabTextStyle}" Margin="5,5" DockPanel.Dock="Bottom" FontFamily="Eras ITC" FontSize="13" Text="Service"/></DockPanel></TabItem.Header><views:ServiceView    x:Name="ServiceView" VerticalAlignment="Top" Height="615"/></TabItem>

Our application uses WPF.

One Window includes TabControl. Each tab header includes image and text.

When the tab is selected, we need to show different image and text in different color.

One way is to create a customized control which include image and textblock. And one of dependency property is "Select".

When Select is true, use different image and set different Foreground for textblock.

Our question, could we use style to achieve this? thx!

It would be very useful to pass DataContext as parameter for DataTemplate:

<DataTemplate><DataTemplate.Resources><ObjectDataProvider x:Key="ServiceDataProvider" ObjectType="{x:Type control:ServiceLayout}"><ObjectDataProvider.ConstructorParameters>
                /*here could be DataContext..but how?*/</ObjectDataProvider.ConstructorParameters></ObjectDataProvider></DataTemplate.Resources><ContentPresenter
               Content="{Binding
                    Source={StaticResource ServiceDataProvider}}" /></DataTemplate>

I will use this DataTemplate in ListBox ItemTemplate. So, DataContext will be ListBoxItem bound object (type is known), and it is not very well to use ViewModel added as static resource as in https://social.msdn.microsoft.com/forums/vstudio/en-US/38a80213-9e72-44fc-8338-1a8bcfcf9c9f/objectdataprovider-binds-to-datacontext

May be there are any other ways to pass parameter to constructor from DataTemplate?

Hello,

  I am trying to debug some of my code for a set of WPF buttons.   I am stuck with an issue that I cannot get around.  When I launch the debugger from Visual Studio 2013, I get the following in the web browser:

hi,

Can someone tell me  how to know which listboxitem from a listbox was selected by the user?

This is the listboxitem.

<ListBoxItem HorizontalAlignment="Left" Name="Canvas" Foreground="White"  FontSize="60" Background="White" BorderBrush="White" Width="763" Height="72"  >

The following are not working

 if (MyList.SelectedItem.ToString() == "Canvas")
            {
                canvaswindow cw = new canvaswindow();
                cw.Show();
                this.Close();
            }


 private void ListBoxItem_Selected_1(object sender, RoutedEventArgs e)
        {
            if (MyList.SelectedItem.ToString() == "Canvas")
            {
                canvaswindow cw = new canvaswindow();
                cw.Show();
                this.Close();
            }
        }

Thanks,

Hi all,

Please see the below code. The current work is when mouse over myButton then set textbox value as 3. Then binding this value to ViewModel property, at this time, the new value of ViewModel property also be 3.

The textbox just like a bridge. Can I remove this bridge and change the VM property directly when <setter..... in myTrigger style? thanks.

<Style x:Key="myTrigger" TargetType="TextBox"><Style.Triggers><DataTrigger Binding="{Binding IsMouseOver, ElementName=myButton}" Value="True"><Setter Property="Text" Value="3"></Setter></DataTrigger></Style.Triggers></Style>

Hi,

I have a regular DataGrid from WPF 4.0 RTM, where I put data from database. In order to make clean & light style of DataGrid I use a tall/high rows and by default DataGrid aligns row content in top vertical position, but I want to set a center vertical alignment.

I already tried to use this property 

VerticalAlignment="Center"

in DataGrid options, but it doesn't help me.

Here is an example of XAML-code, describing my DataGrid without center vertical alignment:

<DataGridx:Name="ContentDataGrid"Style="{StaticResource ContentDataGrid}"ItemsSource="{Binding}"RowEditEnding="ContentDataGrid_RowEditEnding"><DataGrid.Columns><DataGridTextColumnHeader="UserID"Width="100"IsReadOnly="True"Binding="{Binding Path=userID}"/><DataGridTextColumnHeader="UserName"Width="100"Binding="{Binding Path=userName}"/><DataGridTextColumnHeader="UserAccessLevel"Width="100"Binding="{Binding Path=userAccessLevel}"/><DataGridTextColumnHeader="UserPassword"Width="*"Binding="{Binding Path=userPassword}"/></DataGrid.Columns></DataGrid>

Result of executing this code:

As you can see all row's content has top vertical align.

What I have to add in order to get center vertical alignment of each row content?

Thanks.

Hi everyone,

I'm making an application that helps user to manages their file.
In my application, I have a list of files and a button Delete all.
I want the Delete all button to be disabled when all files in my list are hidden.

Can anyone help me please ?
Thank you :)

Hi everyone,

I'm currently making an application which encrypt file and users can decrypt the file anytime they want. After encrypting the file, I will delete the original file and when I decrypt, I will re-create the file to original position.

The question is : How can I check if the selected file or folder is in virtual device or removable devices such as CD-ROM ? Because we can not write file on them. 

And how to check if the path is writable or not :) .

Thank you :)

Hello,

I am trying to change the icon of my wpf application mainwindow and the one shown in task bar at runtime using Icon property in Window class and some native win32 api's. When I set the new icon the one on the left corner of mainwindow changes but the running application task bar icon does not reflect the change until I pin the running application to task bar then unpin it. (The application that I am running is not pinned to task bar during start)

What I understood that somehow the task bar is not refreshing the icon immediately.

Below is what I have tried.

//IntPtr hwnd = new WindowInteropHelper(this).Handle;
// Change the extended window style to not show a window icon
//int extendedStyle = GetWindowLong(hwnd, GWL_EXSTYLE);
//SetWindowLong(hwnd, GWL_EXSTYLE, extendedStyle | WS_EX_DLGMODALFRAME);
// Update the window's non-client area to reflect the changes
//SetWindowPos(hwnd, IntPtr.Zero, 0, 0, 0, 0, SWP_NOMOVE |
//	  SWP_NOSIZE | SWP_NOZORDER | SWP_FRAMECHANGED);
//var icon = new System.Drawing.Icon(@"Icon1.ICO");
//ShowInTaskbar = false;
//SendMessage(hwnd, WM_SETICON, (IntPtr)1, icon.Handle);
//SendMessage(hwnd, WM_SETICON, (IntPtr)0, icon.Handle);
//ShowInTaskbar = true;
//SendMessage(GetWindow(hwnd, 4), WM_SETICON, (IntPtr)1, icon.Handle);
//SendMessage(GetWindow(hwnd, 4), WM_SETICON, (IntPtr)0, icon.Handle);
//TaskbarItemInfo.Overlay = new BitmapImage(new Uri(@"App.ico",UriKind.RelativeOrAbsolute));
Icon = new BitmapImage(new Uri("cool.ico", UriKind.RelativeOrAbsolute);

Any help or guidance would be much appreciated.

Thanks

I have a problem setting focus in one of my apps.  The app has a "toolbar" which is just a panel with buttons.  When a button is clicked the appropriate Popup control is made visible.  Each Popup has its own UC for content.

When I open one of the UC's it has several text search controls (my own) which is just a textbox with another popup visible if items are available for selection.  I am trying to get the first of the search controls to obtain focus when the parent popup is made visible.  I have had so many combinations of FocusManager and Keyboard attempts I am now confused.  

It seems that the button which caused the popup to become visible still has the focus no matter what I do.

I've read lots of posts about the problems with focus but none of them have helped my problem.

Hi All,

I am having a really annoying issue which I know there's an easy fix for, but i cannot figure it out for the life of me. My goal is to copy info from an excel sheet to the datagrid. To achieve this, I am taking the clipboard and creating a datatable, and from the datatable --> datagrid. I have finally got the datagrid to display the correct column names and number of rows, but the records are showing "System.Data.Row" instead of the row's ItemArray. I've debugged the datatable and the correct info is right there in the ItemArray properties. Can someone please help me resolve this issue?

Thanks in Advance!!!

Here's my code:

private void button1_Click(object sender, RoutedEventArgs e)
        {
            string s = System.Windows.Clipboard.GetText();
            string[] lines = s.Split('\n');

            string[] columnsNames = lines[0].Split('\t');
            lines = lines.Where(w => w != lines[0]).ToArray();
            DataTable dt = new DataTable();
            DataRow dr;
            List<DataRow> list = new List<DataRow>();

            foreach (string str in columnsNames)
            {
                dt.Columns.Add(str, typeof(string));
                DataGridTextColumn dgtxcol = new DataGridTextColumn();
                dgtxcol.Header = str;
                dataGrid1.Columns.Add(dgtxcol);
                dgtxcol.Binding = new Binding(".");
            }

            for (int row = 0; row < lines.Length; row++)
            {
                string[] rowInfo = lines[row].Split('\t');
                dr = dt.NewRow();
                for (int z = 0; z < rowInfo.Length; z++)
                {
                    if (rowInfo[z].Contains('\r'))
                        rowInfo[z] = rowInfo[z].Replace('\r', ' ');
                    dr[columnsNames[z]] = rowInfo[z];
                }
                dt.Rows.Add(dr);
            }
            list = dt.AsEnumerable().ToList();
            dataGrid1.ItemsSource = list;
            string name = ((DataRow)dataGrid1.Items[0]).ToString();
        }

        private void dataGrid1_LoadingRow(object sender, DataGridRowEventArgs e)
        {
            e.Row.Header = (e.Row.GetIndex()+1).ToString();
        }
