Q1 2012 Right Click in RadRichTextBox give unhandled exception OOB

[danparker276]

I downloaded the new binaries and when I right click on a richtext box it errors on me.  This only happens Out of Browser when I'm debugging.  I get the system null reference.
I Made a program with no code behind and only a mainpage with the richtextbox.  Code is below.

<UserControl x:Class="RichText.MainPage"

    <Grid x:Name="LayoutRoot" Background="White">

            <TextBox />
        <telerik:RadRichTextBox Name="rrtbDescription" Grid.Row="4" Width="600" Height="200" Margin="0,10,0,0"
                        DataContext="{Binding}"     IsSpellCheckingEnabled="True"
                        BorderThickness="1" BorderBrush="Black" IsSelectionMiniToolBarEnabled="False"
                     IsContextMenuEnabled="True"

                                     AcceptsTab="False" AcceptsReturn="False"
                        >



        </telerik:RadRichTextBox>
        </StackPanel>
    </Grid>
</UserControl>

Any ETA on this.  I want to avoid switching back to the last release.

Hello Dan,

This problem has been fixed in the development version and the fix will be visible in the next LIB which will be uploaded next Tuesday. The fix will also be included in the service pack coming in the middle of March.

Still has the same problem in 2012 Q1 SP1, when right click on a table cell.  This is an in browser app.

When I right click, the context menu show for like 0.2 second then with this error:

Line: 56
Error: Unhandled Error in Silverlight Application
Code: 2531    
Category: ParserError       
Message: Failed to assign to property 'System.Windows.Controls.ContentPresenter.Content'.     
File:      
Line: 6058     
Position: 65

A workaround is to disable the "Insert..." in the context menu.

        static void _noInsertTableMenu_Showing(object sender, Telerik.Windows.Controls.RichTextBoxUI.Menus.ContextMenuEventArgs e)
        {
                        // Get
            var groups = e.ContextMenuGroupCollection;


            foreach (Telerik.Windows.Controls.RichTextBoxUI.Menus.ContextMenuGroup g in groups)
            {
                if (g.Type == Telerik.Windows.Controls.RichTextBoxUI.Menus.ContextMenuGroupType.TableCommands)
                    g[0].Visibility = System.Windows.Visibility.Collapsed;
                
            }
            
        }

[Edward]

Just to add, it seems that simply set g[0].Icon = null would fix this issue, without changing the visibility to collapsed.

Using Vista theme.

I don't have any problems since the fix.  I'm also not using tables in my richtextbox though.

Hi Edward,

Thank you for your feedback and the possible workaround. Unfortunately we couldn't isolate this problem. 
In Q1 SP1 2012 the context menu properly opens inside table in both in and out of browser modes. Dan has also confirmed that the issue has been resolved in the latest version.

Can you give some more details, so that we could look into the issue?
