Hello, Everybody, 

I am stuck with a wiered issue since yesterday . I am making a WPF windows Desktop Application

using WPF Ribbon Control . I created the whole application on my machine Windows 8.1. All worked perfect. 

But When I deployed it on a Windows 7 Machine. 

It started throwing exception at start of the application. here is my simplified code, The problem i found is due to Ribbon Control. As soon as i remove the line

<Ribbon x:Name="MainRibbon" RenderTransformOrigin="0.9,0.797" >

all errors go away. I am attaching screenshots here for the erors

<Window x:Class="CAD_IMS.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

Please help me out of this . 

This error when i run on windows 7 Machine.

Thank You

.

This is when i debug with VS 2010

This is inner exception

Richtextbox is five.

Richtextbox contains letters to color.

I want to save the contents of the five Richtextboxinto one file.

is it possible?

And I want to import content from a file.

I'm trying to change the look of a button which is in the DataTemplate of a ListView.ItemTemplate, this Button has got a Path for the content instead of a string, this works fine by default, but I can't seem to get the Path to go in my ControlTemplate in the Style. 

This is the ListView XAML

<ListView ItemsSource="{Binding Views}"
                  ItemContainerStyle="{StaticResource ListViewMenu}"
                  Grid.Row="1"
                  Grid.Column="0"
                  BorderBrush="Transparent"
                  Background="Transparent"
                  ScrollViewer.CanContentScroll="False"><!--Visibility="{DynamicResource NavigationVisible}"--><ListView.ItemsPanel><ItemsPanelTemplate><StackPanel Orientation="Vertical" /></ItemsPanelTemplate></ListView.ItemsPanel><ListView.ItemTemplate><DataTemplate><Button Command="{Binding Navigate}" Style="{StaticResource test}"><Path Data="{Binding IconGeometry}" Stretch="Fill" Width="40" Height="40" Fill="Black"/></Button></DataTemplate></ListView.ItemTemplate></ListView>

And this is the style, at the moment there is just an empty dot, which I will show in an image below the Style:

<Style TargetType="Button" x:Key="test"><Setter Property="Template"><Setter.Value><ControlTemplate><Border BorderBrush="Red" BorderThickness="2" CornerRadius="20"><ContentPresenter Width="20" Height="20" /></Border></ControlTemplate></Setter.Value></Setter></Style>

I have a question regarding resolution independence in WPF. I have two images below. The first one is at a lower resolution, and the second is at a higher resolution. Here they are;

The DataGrid is simply in a TabControl which is within the main Grid. However, the bottom part of the UI is now within a ViewBox. I did this so that it would scale with the resolution. This has worked OK, it is much better than before however now on the larger resolutions the ViewBox makes the content larger than I would prefer, and the smaller resolution smaller than I prefer.

My question really would be is there a way to limit the size that the ViewBox scales up to? I would like, in the second image, for the DataGrid section to be a little larger and the second half of the content to be a bit smaller. I'm a bit hesitant to post the whole XAML because it's quite a lot of code but here's the content in the ViewBox;

I am trying to add a resourcedirectory in App.xaml, but I cannot seem to get VS to recognise that the folder and file are there.

No matter what I do, I am returned with this:

An error occurred while finding the resource directory "Themes\Styles.xaml".

I am trying to install the WPF dark theme by Dan Pristupov found at https://github.com/DanPristupov/WpfThemes, but am having a lot of trouble simply adding the styles file as a resource.

Is this something I am doing wrong, I have done this many times with other things with no problems.

Hi Everyone,

I have developed a WPF application with HockeyApp (third party tool - to track silent crashes). I am getting lots of crashes nearly sixty thousand crashes logged as COM exception.

Frankly, I don't have any knowledge about this and to solve this issue. So can you guys please guide me resolve this issue.

Please see the stacktrace as below;

Steps to reproduce:

1. I log into a non-admin user account (Windows 10 machine)
2. I launch a WPF application (an empty WPF application from the default VS templates will do)
3. I switch users from my non-admin account to my admin account
4. Open the task manager and watch the memory consumption of my WPF application grow

Other notes:

• Memory consumption goes up at about .1 MB a second
• I've reproduced this bug with .NET framework versions 4.5 and 4.6
• I had the bug tested by 3 users on 3 "uncorrelated" machines (all running Windows 10) and the bug reproduced for 2 out of the 3 users
• The bug does not reproduce if I run the app in my admin account and switch to my non-admin account 

Hi,

I have an MVVM application with a TabControl. The content of the tab is a UserControl i created.

I created a TabControl and binded the ItemSource to a collection in the ViewModel like this:

<TabControl HorizontalAlignment="Left" Height="696" Margin="429,0,0,32" VerticalAlignment="Bottom" Width="552" ItemsSource="{Binding TabCollection}"/>

In the ViewModel I initialize  the collection in the constructor :

 //**** Initilize TabCollection with fake data (temporary)
            TabCollection.Add(new TabItem { Header = "בדיקה1", Content = new CatagoryTab() });
            TabCollection.Add(new TabItem { Header = "בדיקה2", Content = new CatagoryTab() });

So two questions:

1. which class or part of class should be responsible for populating the TabCollection with data? Should I, instead of the above example, create a Model for the TabCollection which will be responsible to populate itself in the constructor? Or is it fine like this?

2. Should the UserControl have it's own ViewModel?

Thank you very much!

Hello Everyone,

We currently are using the XBAP application on IE 11 which was initially developed in 2009 and are maintaining it since it helps us integrate with a third-party web application.

Would like to know if XBAP is still being actively supported by Microsoft? The reason is we're facing some issues with reading secure cookies and need to probably raise a ticket with Microsoft so would be helpful to know this information.

Thanks,

Smeetha

I have a TextBox inside a StackPanel, and I an trying to get the textbox to fit the window dynamically so when it is resized, the textbox follows.

I am used to building websites, but obviously width=100% isn't going to work here, but setting the HorizontalAllignment to Stretch as I found online also did nothing.

I added the line to my StackPanel, and that is now 100% width, but it isn't working for the TextBox.

<StackPanel Orientation="Horizontal" Margin="0,0,10,0" HorizontalAlignment="Stretch"><Label Content="Description " /><TextBox HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Margin="0,2,10,2"/></StackPanel>

I wanted to find a method of firing an event when the TabItem of a Page is selected. I had a look around and found that placing a Label on the header and using MouseLeftButtonDown was a way of making this event fire. The XAML looks like this;

<TabItem><TabItem.Header><Label Content="Archived Jobs"  MouseLeftButtonDown="CallArchivedJobsTabItemSelected"/></TabItem.Header></TabItem>

There is an issue with this fix though, in that if the user clicks in a specific place under the Label they will be able to select the TabItem without the event firing. How can I program this differently to ensure that they cannot bypass the event firing? The kind of code that it is firing is something like;

if(tabItem1.IsSelected == true)
{
 // Do Something
}

if(tabItem2.IsSelected == true)
{
 // Do Something
}

I have tried using GotFocus on the TabItem and SelectionChanged on the TabControl. GotFocus seemed to freeze the UI and SelectionChanged wouldn't let me select from a TabItems DataGrid either.

I have custom scrollbar where thumb (moving part) has image in its center. I need to collapse image when thumb height is less than image height. It seems that there is no way to trigger on current height of thumb (i tried height and actualheight properties, both are wrong).

hi, this is something i have never learned before but i have seen it been done...

how do i add an event onto a control that doesnt have that event,  

example, wpf grid has only a "grid.MouseDown" event... how do, if possible add my own "grid.MouseDoubleClick"

can anyone show me please...

I have this working but I'm guessing (hoping?) there's an easier way.

I have a ListBox on a WPF form with Extended Selection mode and the user can remove items from that ListBox. For easy sorting the list items are stored in a List(Of String) called and LstExifEditTags2ListSort and ListBox is filled like this:

Me.LstExifEditTags2.ItemsSource = LstExifEditTags2ListSort

I know I need to manipulate List(Of String) once it becomes the item source and Initially I had this to remove the items:

For Each LstItem In Me.LstExifEditTags2.SelectedItems
      LstExifEditTags2ListSort.Remove(LstItem)
Next
Me.LstExifEditTags2.Items.Refresh()

But that simply deleted the first instance from the list that matched that particular selected item string. So, if the user selected an item near the end of the list that was the same as an item near the start of the list, the first one (near the start of the list) would get deleted and NOT the one the user actually selected.

I couldn't find a way to get index of the selected item in the ListBox so as to match it up with an item in the List(Of String). I ended up looping backward through the selected items, then looping backward through the List(Of String) while the List(Of String).Equals was either equal to the selected item or the counting variable was less than 0. Thusly:

                For i = Me.LstExifEditTags2.SelectedItems.Count - 1 To 0 Step -1
                    LstCount = LstExifEditTags2ListSort.Count - 1
                    While LstCount > -1 And Not LstExifEditTags2ListSort.Item(LstCount).Equals(Me.LstExifEditTags2.SelectedItems(i))
                        LstCount -= 1
                    End While
                    If LstExifEditTags2ListSort.Item(LstCount).Equals(Me.LstExifEditTags2.SelectedItems(i)) Then
                        LstExifEditTags2ListSort.RemoveAt(LstCount)
                    End If
                Next i

So, my question is two fold:

1. Is there an easier way to do this?? (seems like there should be)

2. Does the .Equals simply do a string comparison or is it doing something more like comparing the position of the two things in each list.

Many thanks for any insight that can be offered.

Best,
Ken

Hi,

I just tried to apply some values to the transform properties in the trigger setter. Unfortunately it is throwing the error in the intellisense as "Nested types are not supported: (RenderTransform.TransformGroup[0]".

Hereby, I have shared the code,

<ControlTemplate TargetType="{x:Type ToggleButton}"><Grid Height="Auto"><!-- Other Codes --><Border Grid.Column="1"><Path x:Name="PathData"
                          Data="M0,0L25.194,16 0,32z"
                          Fill="#FFFFFFFF"
                          RenderTransformOrigin="0.5,0.5"
                          Stretch="Uniform"><TransformGroup><TransformGroup.Children><RotateTransform Angle="0" /><ScaleTransform ScaleX="1" ScaleY="1" /></TransformGroup.Children></TransformGroup></Path></Border></Grid><ControlTemplate.Triggers><Trigger Property="IsChecked" Value="True"><Setter TargetName="PathData" Property="(RenderTransform.TransformGroup[0].Angle)" Value="90" /></Trigger></ControlTemplate.Triggers></ControlTemplate>

However I can able to get this one by replacing the Data of the Path in the trigger.  

But I want to know, why I am not getting this one by using the above method.

Thanks in advance.

Another question... (This is a problem i come accoss VERY often, but i usually try to work around it)

i have a loop lets say:

dim MyStack as new stackpanel
MyStack.orientation = orientation.Vertical

for each Filestring as string in system.io.directories.getDirectories("C:\", "*.*" , TopDirectories)
dim MyButton as new button
MyButton.Content = Filestring.remove(0,(Filestring.lastIndexOf("\")+1))'That is the get ONLY the name of the folder.
AddHandler Mybutton.Click,AddressOf MyButtonClick
'
MystackPanel.Children.Add(MyButton)

 Next

and then:

Private Sub MybuttonClick()

//''Do some stuff
End Sub

My question is, that im NOT allowed to link an address with values in like the sender or event args, i.e i cant link this:
Private Sub MyButtonClick (Byval sender as Object, Byval e as System.Windows.RoutedEventArgs)
End Sub

VB wil Give me a big error... now thats fine and dandy,,,, but my question is if im not allowed to send the sender, will will i be able to use the SENDER as button in the event i addressed, because its not publically declared, so i cant use it that way.

is it possible to send the button to the event as sender in able to use it  or not?

FileStream fileStream = new FileStream("RTBDocument.rtf", FileMode.Open);
TextRange range = new TextRange(richtextBox1.Document.ContentStart, richtextBox1.Document.ContentEnd);
range.Load(fileStream, DataFormats.Rtf);

i am Load the RTBDocument.rtf file to richtextBox1.

richtextBox1 search only "I'm happy"

And I want to be display "I'm happy(with Color )"  in richTextBox2.

richTextBox1 (good morning nice to meet you I'm happy..) -> find (I'm happy) -> richTextBox2 (I'm happy)Show

please answer about my question.

Hi, it's for a health application  .


Let's say that i have these  entities

 public partial class EXAMINATION
{
        public int ID_EXAMINATION { get; set; }
        public int ID_PATIENT { get; set; }
        public System.DateTime DT { get; set; }
       public List<TEST> TESTS { get; set; }
}

 public partial class TEST
{  
        public int ID_TEST{ get; set; }
        public string TITLE { get; set; }
 }
 so each EXAMINATION may have 0..n TESTs

and i have  a datagrid bound to ObservableCollection<EXAMINATION> .

what i want to get is , a grouping based on TEST

any help is welcome
