After installing 2011 Q2, I get a NullReferenceException:
This happens after I load the data (22 rows). The first 11 are visible. It happens repeatedly with this set of data but no problem with other data. Went back to 20010 Q2 SP2 and it works fine.
System.NullReferenceException occurred Message=Object reference not set to an instance of an object. Source=Telerik.Windows.Controls.GridView StackTrace: at Telerik.Windows.Controls.GridView.Automation.GridViewCellAutomationPeer.GetNameCore() in c:\TB\102\WPF_Scrum\Release_WPF_40\Sources\Development\Controls\GridView\GridView\GridView\Automation\GridViewCellAutomationPeer.cs:line 146 InnerException: This happens after I load the data (22 rows). The first 11 are visible. It happens repeatedly with this set of data but no problem with other data. Went back to 20010 Q2 SP2 and it works fine.

Hello,
I am using a hierachical RadGridView and when i expand a GridViewRow, the first time it expands, the childDataControls list count is 0. If i collapse the row , the event is fired again and the childDataControls list is populated. I need to get the row's childDataControls on the first expand event, is it possible?
I'm trying to select a row's childDataControl (RadGridView) the first time that row is expanded.
What would a different approach be?
private void myGrid_RowIsExpandedChanged(object sender, RowEventArgs e)
{
GridViewRow r = e.Row as GridViewRow;
var childControls = r.ChildDataControls;
}

I have a TreeListView that is bound to an ObservableCollection datasource.
In the radTreeListView1_CellValidating method I change another cells value depending on certain things. That change is not visible on the TreeListView. But if i click on the cell that was suppose to change. It's value updates to what it should be..
So it looks like datasource gets the change but the view does not refresh until cell gets focus.
Help?

I use the latest internal build RadControls_for_WPF40_2011_2_0912_DEV_hotfix.
It seems like the RichTextBoxUI:RadRichTextBoxRibbonUI.RichTextCommand="{Binding Path=OpenDocumentCommand}
no longer likes to open *.docx -files.

Hi There,
The online documentation suggests that the RadTreeListView may be customized/templated within Expression Blend by selecting the item and clicking 'Object -> Edit Additional Templates -> Edit <Template/Style> -> Edit a Copy...'.
However, when selecting the RadTreeListView in Expression Blend 4, the 'Edit Current' and 'Edit a Copy' menu items are not enabled. This is true for every style and template in the list of available templates to edit.
How can I get this to work? I'd like to use this control for an important project but it will require additional customization.
Thanks.

Hello,
I try to implement CustomFilterDescriptor
My grid Has four rows :
1. FirstName
2. LastName
3. Address
4. Age
I want to filter only 1. 2. and 3. column.
When I Type 'John Doe'
I want to look for row that some columns contains John in cell and Doe (Doe can be in another Cell but in the same row!)
is it possible?
I tried to split my Filter value
and add FilterDescriptor for every splited word with every column but Logical operator is set for every filterDescriptor

I like the expanded clipboard operations. Let me as you this. Since so many users always want to mimic excel spreadsheets, is it possible to select one cell, copy the value from it, then select multiple destination cells and paste that one value to each of the cells selected?
