Hello,

I have a TabControl with many items and I would like to activate the DropDownButton which shows a menu containing all TabItems.
As far as I can tell this feature should be supported as there is an IsDropDownOpen Property which shows me such a menu but I can't figure out how to get this menu during runtime.

In addition I'm looking for a way to change the appearance of the Left- and RightScrollButton (for the drop down button i've seen that there is a DropDownButtonStyle Property but I did not play around with it since I don't see this button at all yet).

I hope you can help me on these issues.
Thanks,
Peter

Styling header cells disables column resize

Hi,

I'm slowly getting to grips with styling the GridView control. So far I've styled the GridViewRow and GridViewHeaderCell. However I have noticed that somethin in my styling for GridViewHeaderCell (or maybe something I've left out) is causing the column resize functionality to stop working. Even if I fully define CanUserResizeColumns="True" on the grid itself, it still doesn't work. By commenting out all my GridViewHeaderCell style XAML the problem disappears, so its in there somewhere! Any help would be much appreciated.

Style loss after upgrading to WPF 2010 SP2

Hello,

Recently we have upgraded our Telerik dlls to 2010 SP2 (had the 2010 Q1 before).
We found that some of our custom style templates for the RadGridView are no longer applied for some reason.
For example, our GridViewPanel style, our GridViewFooter style etc.

Please note - we are using implicit styles (no x:Key on the style, just TargetType).
How should we fix this? I saw you had mentioned that " All RadControls skins now get a major facelift. Your custom themes might not work as expected" - but this is rather vague and does not allow me to find out why the styles aren't applied now or how should I fix this.

To make things worse, after the Telerik upgrade, Blend does not open the solution anymore, neither does it give me any error messages.

I'd appreciate some help, Tx.
Gili

GridViewDataColumn.BackGroundColor

When we set the GridViewDataColumn BackGroundColor sometimes the selected-row-color hides behind the columncolor and sometimes it does not.

Example:

Using Background="#20FF0011" the selected-row-color appeares as aspected.

Using Background="#CCFFCC" the selected-row-color hides behind the colomn.

Why this difference?
