Hi,

I'm using Telerik V2011.3.1116.35 and VS2008. I have a RadWindow with multiple Telerik components inside of it. When in the designer part I click on my RadRichTextBox I receive the following message in my designer:

Exception has been thrown by the target of an invocation.

We have problems in scrolling datagrid with long description column. If the display value for a column is not too long, the scrolling is working properly. However if there is a long description shown in a column as shown in the attached screen, the screen will hang when scrolling in the datagrid and the WPF window cannot be recovered until closed and reopened. The no of records are not that large and are around 600 only. Below is the reference code. Please advice the solution.

I have a 3d bar chart displaying but the edges are not smooth.  Is there a way to enable anti-aliasing for it?

Is there a way to disable that behaviour?

Thanks,

Hi,

I just upgraded Telrik from V2011.3.1116.35 to V2011.3.1205.35 and I realised that Telerik.Windows.Controls.DataServices.dll and Telerik.Windows.Controls.EntityFramework.dll still at V2011.3.1116.35 :( Is this normal???

Thank's

Hi,

I got one problem of RadGridView with Hierarchy gridview structure.

Configuration:
WPF app for .NET Framework 4
Windows 7 (x64) Professional
Telerik Version: RadControls for WPF Q2 2011 SP1(2011.2.0920)

I show the data to user using the following hierarchy:

RadGridView (Level 1)
+---- RadGridView (Level 2)
+-------------- RadGridView (Level 3)

It works fine in normal data databinding. Three level of gridvews can be shown.
i.e.

When i add a converter in binding in Level 3 grid, during runtime it shows only the Level 1 grid (the topmost one) with "+" that's not expandable. If i add a converter in binding in Level 1 and Level 2 grid, it also works fine. Three levels expandable grid could be shown.
i.e.

my xaml code for gridview.



If i use a debugger it shows that i have exception: NullReferenceException that's throwed from GridViewRow.OnIsExpandedChanged.

The error message.
Sysem.NullReferenceException : 
    {"Object reference not set to an instance of an object"}

Data:    
    System.Collections.ListDictionaryInternal

I found a thread that is talking a similar scenario. And you reply that the problem could be fixed by getting the latest version of build.
But it seems that it does not work in my scenario.
http://www.telerik.com/community/forums/wpf/gridview/nullreferenceexception-in-gridviewrow-onisexpandedchanged.aspx

Any suggestion for my scenario?

I have created a window with a rich text box and the rich text box ribbon control.

I can use it, except for when I attempt to add a symbol.

The steps to crashing it are as follows:

• In the ribbon bar, select Insert
• Click on the Symbol button
• Click on any symbol
