Hi, i have some problem.

The image editor created by wpf works normally. However, if you link to other programs, you will not see all the components. (Please refer to attached file)

I don't know why act like that. I look forward to your valuable feedback.

Thanks

Close button in one RadTabItem

I want to ad a close button to 1 out of 2 RadTabItems. The documentation ads the button to all RadTabItems. How can I do this?
My xaml code is as follows (and I want the close button on the second RadTabItem, never the first one):

    
            <telerik:RadTabControl> 
        
            <telerik:RadTabItem Header="{Binding ElementName=operationContentControl, Path=Content.DataContext.Header}" IsSelected="{Binding IsOperationSelected, Mode=TwoWay}"> 
        
            <ContentControl x:Name="operationContentControl" cal:RegionManager.RegionName="{x:Static infrastructure:RegionNames.MainRegion}" /></telerik:RadTabItem> 
        
            <telerik:RadTabItem Header="{Binding ElementName=protocolContentControl, Path=Content.DataContext.Header}" IsSelected="{Binding IsProtocolSelected, Mode=TwoWay}" Visibility="{Binding IsProtocolVisible, Converter={StaticResource boolToVisibilityConverter}}"> 
        
            <ContentControl x:Name="protocolContentControl" cal:RegionManager.RegionName="{x:Static infrastructure:RegionNames.ProtocolRegion}" /><telerik:RadTabItem> 
        
            </telerik:RadTabControl>

Get RichTextBox in CellEditTemplate form the code behind

How can I assign in the code behind a German Dictionary to a RichTextBox in the CellEditTemplate?

01.<telerik:GridViewDataColumn.CellEditTemplate>

02. <DataTemplate>

03. <Grid>

04. <telerik:RadRichTextBox x:Name="ProtocolRowTextBox"

05. IsSpellCheckingEnabled="True"

06. BorderThickness="0"

07. Height="Auto"

08. Margin="0"

09. DocumentInheritsDefaultStyleSettings="True"/>

10. <telerik:TxtDataProvider RichTextBox="{Binding ElementName=ProtocolRowText}"

11. Text="{Binding Path=Text, Mode=TwoWay}"/>

12. </Grid>

13. </DataTemplate>

14.</telerik:GridViewDataColumn.CellEditTemplate>

I can't find the RichTextBox in C# by name and assign it to the dictionary , such as:

1.ProtocolRowTextBox.SpellChecker = _localViewModel.DocumentSpellChecker;

Vertically Merged Cells in a CheckBox Column

Hi,

I have a project in which I am trying to support merged cells for all columns. I notice however that a CheckBox Column doesn't fully support this feature inasmuch as a GridView always displays the values True or False in text form across merged cells (or in my case "1" or "0").

I thought this was an oversight by me but I noticed it in the documentation here where the IsMarried column is shown.

Is this the intended design or does Telerik plan to change this? Personally I would prefer the merged cell also to display a CheckBox.

Many thanks.

Duplicate row group key

I'm having an issue where I sometimes get two groups with a key of empty string when I add a grouping to my data.

It's really important that these group keys be unique because I'm doing some fairly complicated grid navigation in hierarchical grids and I rely on that key being unique so I can programatically make decisions about where to move focus.

Is there a grouping maximum or something that I'm missing, or is this a Telerik bug?

Set the AutoCompleteMode in a style generates an error in my XAML

Hi,

I have following style applied for all my RadMultiColumnComboBox controls (in the app.xaml):

<Style x:Key="DefaultTelerikRadMultiColumnComboBoxStyle" TargetType="telerik:RadMultiColumnComboBox" BasedOn="{StaticResource RadMultiColumnComboBoxStyle}">

<Setter Property="AutoCompleteMode" Value="Search"/>

<Setter Property="FontFamily" Value="{StaticResource DefaultFont}"/>

<Setter Property="FontSize" Value="{StaticResource DefaultFontSize}"/>

<Setter Property="FontWeight" Value="{StaticResource DefaultFontWeight}"/>

<Setter Property="MinHeight" Value="{StaticResource DefaultMinimumHeight}"/>

<Setter Property="KeepDropDownOpen" Value="False"/>

<Setter Property="CloseDropDownAfterSelectionInput" Value="True"/>

<Setter Property="SelectionBoxesVisibility" Value="Visible"/>

<Setter Property="Validation.ErrorTemplate" Value="{StaticResource ErrorTemplate}"/>

<Style.Triggers>

<Trigger Property="IsEnabled" Value="True">

<Setter Property="Background" Value="{StaticResource DefaultTextBoxBackgroundColor}"/>

</Trigger>

<Trigger Property="IsEnabled" Value="False">

<Setter Property="Background" Value="Red"/>

</Trigger>

<Trigger Property="IsFocused" Value="True">

<Setter Property="Background" Value="{StaticResource DefaultTextBoxIsFocusedBackgroundColor}"/>

</Trigger>

</Style.Triggers>

</Style>

<Style TargetType="{x:Type telerik:RadMultiColumnComboBox}" BasedOn="{StaticResource DefaultTelerikRadMultiColumnComboBoxStyle}"/>

With this style applied, I get this error in my XAML files (see attached file): The element "[RadMultiColumnComboBox]" could not be displayed because of a problem with System.Windows.StaticResourceExtension: CollectionView must have value. Parameter name: collectionView.

The error is provoced by the setter of the AutoCompleteMode. The error disappears when this setter is deleted.

Setting the AutoCompleteMode directly on a RadMultiColumnComboBox (with the style applied) does not cause any problems.

Any ideas ??

Regards,
Hans

Scrolling problem in TreeListView when drag-and-drop enabled

In your standard TreeListView sample program, ExpandItemsIntoView, scrolling stops working if I add drag-and-drop parameters as follows:

<telerik:RadTreeListView x:Name="RadTreeListView1"

GroupRenderMode="Flat"
ItemsSource="{Binding}"
Grid.Row="1"
telerik:DragDropManager.AllowDrag="True"
telerik:DragDropManager.AllowCapturedDrag="True">

Is that a problem with the control, or is something else needed to ensure scrolling works? I have this problem in a much more complex example, but I was able to reproduce it in your sample.

Get column and row size in order to center shape in a spreadsheet

Hello

I'm trying to add a picture to a spreadsheet. There is not problement to add the picture, but I'm trying to center it into a merge cell and I can't get the size.

I did the code bellow :

Private Sub addLogo(ByRef worksheet As Worksheet, ByVal columnCount As Integer, ByVal rowCellIndex As Integer, ByVal columnCellIndex As Integer)

Dim image As New FloatingImage(worksheet, New CellIndex(columnCellIndex, rowCellIndex), 0, 0)

Using stream As Stream = Assembly.GetExecutingAssembly().GetManifestResourceStream(String.Concat(Assembly.GetExecutingAssembly().GetName().Name, ".MyLogo.png"))

image.ImageSource = New ImageSource(stream, "png")

image.LockAspectRatio = True

Dim ratio As Double = worksheet.Rows(rowCellIndex).GetHeight().Value.Value / image.Height

image.Height = image.Height * ratio

image.Width = image.Width * ratio

image.OffsetX = worksheet.Columns(columnCellIndex, columnCellIndex + columnCount - 1).GetWidth().Value.Value - image.Width

End Using

worksheet.Shapes.Add(image)

End Sub

the worksheet.Rows(rowCellIndex).Getheight().Value.Value return 20 each time, unless the row is highter

and the worksheet.Columns(columnCellIndex, columnCellIndex + columnCount - 1).GetWidth().Value.Value return 65 each time, for one or more column.

So I don't know the right command to get the height and width of my merge cell, could you help me ?

Thanks
