I have two questions

1) What is the point of the dropdown that you get. If you click on it it is empty

2) How can I add a sortable grid or list to the page? I get content propery is set more than once

Hi all of you,

I am taking advantatge of one UserControl which inherits from one RichTextControl control. I would like to decide in my front-end whether spelling features on it are enable or not. It is not rocket science I suppose but I do not how to implement in my assembly such property..

UserControl project:

                     SelectionChanged="RichTextControl_SelectionChanged" 
                     TextChanged="RichTextControl_TextChanged" KeyDown="RichTextControl_KeyDown" KeyUp="RichTextControl_KeyUp" /> </DockPanel></UserControl>

Client project:

I'm calling this object as it customary:

    xmlns:rtf="clr-namespace:RTFEditor;assembly=RTFEditor"<rtf:RTFBox  SpellCheck.IsEnabled="True"  Height="160" Width="300" Canvas.Left="2" Canvas.Top="3"></rtf:RTFBox>

If I try to put SpellCheck.Enabled="True"  it raises a couple of errors:

Error    1    Property 'IsEnabled' is not attachable to elements of type 'RTFBox'.    C:\puesto\Cuadro_de_Mando\GIT\Vistas\Orden_Reparacion.xaml    119    51    GIT_CuadroMando
Error    2    The attached property "IsEnabled" can only be applied to types that are derived from "TextBoxBase".    C:\puesto\Cuadro_de_Mando\GIT\Vistas\Orden_Reparacion.xaml    119   51    GIT_CuadroMando

How to implement this property in my assembly?

TIA,

Hi there, I am aware that event setters should be used to attach handles in styles. However, can anyone explain this error?

<Window x:Class="WpfApplication1.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"><Window.Resources><Style TargetType="DataGridCell" x:Key="MenuStyle"><Setter Property="ContextMenu"><Setter.Value><ContextMenu><MenuItem Header="Hello!" Click="MenuItem_Click" /></ContextMenu></Setter.Value></Setter></Style></Window.Resources><Grid> <!-- cast target --><DataGrid><DataGrid.Columns><DataGridTextColumn Header="Column" CellStyle="{StaticResource MenuStyle}" /></DataGrid.Columns></DataGrid></Grid></Window>

where the handler is empty (private void MenuItem_Click(object sender, EventArgs e) {}).

Designer is happy with this. However, at runtime, a XamlParseException is thrown ('Set connectionId threw an exception.' Line number '9' and line position '26'.) with this inner exception: "Unable to cast object of type 'System.Windows.Controls.MenuItem' to type 'System.Windows.Controls.Grid'."

I have observed that it tries to cast MenuItem to whatever parent is there to the DataGrid, or, if not parented, to the DataGrid itself.

I don't quite understand why, or what the intent is. Does anybody have a clue?
(I am trying to understand the cause of the exception, not to fix it.)

Thanks,
Jan

Dear all,

I have build a simple WPF application with a simple list box which have as a test following Items layout

<StackPanel Orientation="Horizontal"><TextBlock x:Name="_price" Text="{Binding StringSpecialOfferPrice,UpdateSourceTrigger=PropertyChanged}" Foreground="{DynamicResource ProductPrice}" Style="{DynamicResource DetailCardTitle}" Margin="5,0,0,0"/><TextBlock Text="X" Style="{DynamicResource DetailCardTitle}" VerticalAlignment="Center" Foreground="{DynamicResource ProductDetailMainText}"  Margin="5,0,10,0"/><TextBox Text="{Binding Quantity,Mode=TwoWay,UpdateSourceTrigger=PropertyChanged}" Style="{StaticResource RoundedTextBoxStyle}" Background="Transparent" HorizontalContentAlignment="Center" VerticalContentAlignment="Center" FontSize="20" FontWeight="SemiBold"  Foreground="Black" Width="59" /></StackPanel>

What is happening is that when I touch the TextBox it is not receiving the touch or something prevent it so that I am not able to go in edit mode. Clicking with mouse inside works of course.

I am running it under W7 and Framwework 4

Any reason ?

I have develop a WPF application but I found it really slow when starting up on some computers. I've read the instructions in (Improving WPF applications startup time). And I''ve figured out some ways to improve it.

My application has a great deal of usercontrols. Most of them have animations and they don't need to be displayed immediately after the application is started. How can I load them later when the application really need them?

Setting the visibility to 'Collapsed' or disabling them doesn't work because the code-behind (animations) still runs. And adding these usercontrol programmatically or dynamically will be tedious job. Do you have any better ideas?

Thank you~!

Hi Guys, in my application i'm applying various image effects(Pixel Shader Effects) using 'Shader Effect library'  at the same time i'm using the Sliders for Red, Green, Blue ,Contrast, brightness to change the color over the image. 

The problem; to show the difference of the image effects, i called the ' ViewedPhoto.Effect = null;' for each button click

Once I call the  ViewedPhoto.Effect = null; then the slider "BrightContrastEffect" image effect which are binded with the sliders are not working.

How can i call the "BrightContrastEffect" image effects for the sliders progmmatically?

Kindly help me with this. Thank you

Image Element:

<Viewbox  x:Name="cImage" Stretch="Uniform"  Grid.Column="1" Grid.Row="1" Grid.RowSpan="2" Margin="0"><Image x:Name="ViewedPhoto"   Source="IMG_0071.jpg"

In wpf menu items with children automatically open the submenu when you hover over the item. How do I make it so the submenu only opens when I click on the menuitem? Further, if the user clicks on it while its submenu is open, it should close the submenu. For some reason overriding OnClick() does not call.

This is my Datagrid

In my code behind I have
Class Page1
    Public MyColumn1 As New List(Of String) From {"aa", "bb", "cc"}
    Public MyColumn2 As New List(Of String) From {"dd", "yy", "xx"}
    Public MyColumn3 As New List(Of String) From {"rr", "ff", "dd"}
End Class

What am I missing as the texbox binds aren't showing up
Thanks

Hello there guys,

I wonder why this is happening...

Code: 

<Window x:Class="WpfApplication6.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="MainWindow" Height="350" Width="525"><Grid><ComboBox HorizontalAlignment="Left" BorderBrush="Red" Margin="166,122,0,0" VerticalAlignment="Top" Width="120"/></Grid></Window>

Result under windows7: (expected)

windows 8:

Hello, I'm upgrading a VB6 app to .NET (WPF) and have run into a problem. I have a Checked ListBox and it's populated with a series of class instances that I've pulled into an ObservableCollection so that I can synch the Checkbox Checked state to the collection. All that's working well. But in the VB6 app we have the ability to move a ListBox item up and down in the ListBox. That's where I'm having my problem. I can't seem to figure out how to handle that. 

The first problem is that with the code like it is, when I click on an item in the ListBox, the ListBox doesn't get a SelectedItem, so I don't even have a reference to the item I want to move up or down. I can change that by using RelativeSource in the XAML:

<CheckBox Content="{Binding Path=Name}" IsChecked="{Binding Path=IsSelected, RelativeSource={RelativeSource AncestorType={x:Type ListBoxItem}}}" />

but this will select each item I check and I only really need the last checkbox clicked on to be selected.

The next problem would be the movement of the items in the ListBox. In VB6 it's a simple matter to remove a specific item from a ListBox and then re-insert it back into a different spot. So far the only thing I can think of in .NET is to use a second collection, pulling the items in the correct order from the first collection, then putting them all back into the original collection, now sorted correctly. Seems klunky but I think it would be a straight-forward process to do that.

Also, the VB6 app takes one click to select the item in the CheckedListBox and another click to actually check or uncheck it. This is the action I'd prefer since if I'm only wanting to re-order the items in the list I don't want them to check/uncheck while I'm selecting the items.

I've put together an simple example of what I'm attempting. Here's the XAML:

<Window x:Class="MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525"><Grid><Grid.ColumnDefinitions><ColumnDefinition></ColumnDefinition></Grid.ColumnDefinitions><Grid.RowDefinitions><RowDefinition></RowDefinition><RowDefinition Height="Auto"></RowDefinition></Grid.RowDefinitions><ListBox Name="lst" SelectionMode="Multiple"><ListBox.ItemTemplate><DataTemplate><CheckBox Content="{Binding Path=Name}" IsChecked="{Binding Path=IsSelected}" /></DataTemplate></ListBox.ItemTemplate></ListBox><StackPanel Orientation="Horizontal" Grid.Row="1"><Button Name="btnMoveUp" Margin="3" Click="btnMoveUp_Click">/\</Button><Button Name="btnMoveDown" Margin="3" Click="btnMoveDown_Click">\/</Button></StackPanel></Grid></Window>

Here's my Code-behind:

Imports System.Collections.ObjectModel

Class MainWindow
    Private objects As New ObservableCollection(Of clsObject)

    Private Sub lst_SelectionChanged_1(sender As Object, e As SelectionChangedEventArgs)
        Debug.Print("SelectionChanged")
    End Sub

    Private Function FillObjectCollection() As Boolean
        For x As Integer = 1 To 10
            Dim obj As New clsObject(x, "Object " & x.ToString, "Test Description " & x.ToString, x, False)
            objects.Add(obj)
        Next
        objects(3).IsSelected = True
        objects(6).IsSelected = True
        objects(7).IsSelected = True
    End Function

    Private Sub MainWindow_Loaded(sender As Object, e As RoutedEventArgs) Handles Me.Loaded
        FillObjectCollection()
        lst.ItemsSource = objects
    End Sub

    Private Sub btnMoveUp_Click(sender As Object, e As RoutedEventArgs)
        Dim obj1 As clsObject = DirectCast(lst.SelectedItem, clsObject)
        If obj1.Sequence > 0 Then
            Dim tmpSequenceID As Integer = obj1.Sequence
            For Each obj2 As clsObject In lst.Items
                If obj2.Sequence = tmpSequenceID - 1 Then
                    obj1.Sequence = obj2.Sequence
                    obj2.Sequence = tmpSequenceID
                    ' now how to resort the ListBox?
                End If
            Next
        End If
    End Sub

    Private Sub btnMoveDown_Click(sender As Object, e As RoutedEventArgs)

    End Sub
End Class

And here's the class I'm using for my objects:

Hello all,

I am new in WPF and I work on simple multitouch program. Basic idea is to show JPG images from folder and let user to move, rotate and zoom them on screen. I have done all this - reading files from folder, creating ObservableCollection and bind it to itemsControl. It works well, but I am not able to bring last manipulated image to top.

I found some examples like that, but it doesn't work with dynamicaly bound objets.

   Private Sub Window_ManipulationStarting(ByVal sender As Object, ByVal e As ManipulationStartingEventArgs)
        e.ManipulationContainer = Me

        Dim element As FrameworkElement = CType(e.Source, FrameworkElement)
        Dim pnl As Panel = CType(element.Parent, Panel)
        For i As Integer = 0 To pnl.Children.Count - 1
            If pnl.Children(i) Is element Then
                Panel.SetZIndex(VisualTreeHelper.GetParent(pnl.Children(i)), pnl.Children.Count)
            Else
                Panel.SetZIndex(VisualTreeHelper.GetParent(pnl.Children(i)), i)
            End If
        Next

        e.Handled = True
    End Sub

Any advice wil be welcomed.Thank you

Miroslav

 I have 2 different windows and I want to keep the scroll only in one of them. I've posted the xaml code where the scroll can be found, the code that triggers when the user selects and image, and also a few illustrative screenshots. I hope I made myself clear. If you need more details, don't hesitate to ask.

<k:KinectScrollViewer Grid.Row="0" Name="scrollViewer" HorizontalScrollBarVisibility="Visible"  VerticalScrollBarVisibility="Disabled"><WrapPanel VerticalAlignment="Center" x:Name="wrapPanel" Orientation="Vertical" k:KinectTileButton.Click="KinectTileButtonClick"><!-- items for design layout.  They will be replaced at runtime. --><k:KinectTileButton Label="1"/><k:KinectTileButton Label="2"/><k:KinectTileButton Label="3"/><k:KinectTileButton Label="4"/><k:KinectTileButton Label="5"/><k:KinectTileButton Label="6"/><k:KinectTileButton Label="7"/><k:KinectTileButton Label="8"/><k:KinectTileButton Label="9"/><k:KinectTileButton Label="10"/><Image Height="150" Name="image1" Stretch="Fill" Width="200" /></WrapPanel>

            if (button.Tag is WineGroupModel)
            {
                C1 C1 = new C1(); //mainwindow
                C1.ImagesDir = (button.Tag as WineGroupModel).WinesDir;
