StackOverflowException is thrown when perfoming sorting, filtering or grouping on GridView bound to DynamicObject

Resolved with LIB version 2014.1.0428.

Scrolling performance is degraded when RowStyle/RowStyleSelector that sets Template property is explicitly applied

'Cell is already in the collection' exception is thrown when multiple cells are copied and pasted in a sorted column

ViewRow's background is not correctly colored when RadGridView is within RadBusyIndicator and it is busy. There is no problem if your are using GridViewLoadingIndicator.

HeaderCheckBoxStyle of GridViewSelectColumn returns TextBlock as Header in Office2013 theme

Hello Telerik  Team!

Are there any new informations concerning the below BUG?
(UniqueName-Property is causing binding errors) 
Is this fixed in one of the current versions? What are proper workarounds?

Identical Problem for Sylverlight:

GridViewColumn's IsVisible Binding breaks when you create an instance of a usercontrol.

When the ScrollMode is set to Deferred, then only the vertical ScrollBar shows a position indicator. The same is requested on horizontal scrolling.

Scrollbar scrolls unexpectedly when column width is changed. Check the following video for a reference:

1. Set RadGridView's setting DragElementAction="ExtendedSelect". 
2. Open a window on selecting a row.
3. Close the window, the RadGridView becomes ExtendedSelect.

Note: Most probably this problem is actually caused by a limitation in the Silverlight platform. Once a Window is shown, there is no way to detect that the mouse is released.

This Style is not applied when Windows8 Theme is set for the GridView (only) - it works if an ApplicationTheme is set. 
<telerik:RadGridView  telerik:StyleManager.Theme="Windows8" Name="clubsGrid" .../>

<Style TargetType="telerik:GroupHeaderRow" telerik:StyleManager.BasedOn="Windows8">

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

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

</Style>

When KeyboardNavigation.TabNavigation is set to Once, RadGridView does not lose the focus after the second time it's focused.

Change AlternateRowBackground (runtime) has only effects after scrolling in grid or after rebinding it.

Just run the attached project and scroll horizontally to the very end several times (at least two times).
I tried disabling the column virtualization but this did not help.

This issue will be resolved with Q2 2015. 
A new virtualization mechanism for ColumnGroups will be introduced with Q2 2015. A property EnableColumnGroupsVirtualization is exposed with default value True for enabled virtualization. Setting it to False will enable the old logic. 

1. Define a custom AggregateFunction for a column
2. Group on a column
3. A calculation on the AggregateFunction is invoked
3. The Grouping.Key (of the input parameter) corresponds to the correct key
4. Edit a value on the column (having the AggregateFunction)
5. A calculation is invoked, but the Grouping.Key is "1" and not the correct key.

The group panel item image of a column with custom header is blurred

Columns with * width are not measured correctly when GridView is placed in ScrollViewer and its width is changed.
