We are using a RadRibbonWindow in an application (running on Win 7). When the application starts, there is a lot of black areas where comtrols (RibbonBar, tabs etc.) normally are placed, and when moving the mouse pointer around in the RadRibbonWindow, the controls are showing and the black fields disappear. This also happens if i by using the mouse drags the window so it's size gets smaller or larger.

The problem started after i upgraded to version 2010.2.812.40 of the radcontrols. Is this a bug, or is there something i have missed?

RadGridView in RadDockManager & Virtualization

Hello,
I'm using an MVVM pattern in a WPF application with RadDocking ... I've got some RadGridView inside usercontrols and they perform poorly with horizontal and vertical scroll... I've searched this forum and the problem seems to be a missing height/width on the RadGridView... since I've defined in me Shell a 1024*768 width have I for each UserCotrol to specify a default width/height? how can I set it to the parent content?

I've also some master/detail gridview that uses a behavior to fill the child RadGrid...those performs worst... have I to specify an height/width as well?

Thanks

Paolo

Winform RadGridView vs WPF RadGridView

I've written a module to export data from a WinForm RadGridView to excel. The module handles grouping as well. 
Now that we have ported over to WPF, that module doesn't work anymore.


Below are the RadGridView Winform objects, properties or methods. What are the equivalents in WPF?
GridViewChildRowCollection
GridViewRowInfo
row.ChildRows
row.Group
row.HierarchyLevel
row.Group.GroupRow.HierarchyLevel
DataGroupCollection
DataGroup
group.Groups.Count
grid.ColumnCount

RibbonWindow and docking

Hello

I found a bug i cannot solve on my own

When you put RadDocking on RadRibbonWindow
Compass gets a strange translation to the right and bottom
same as all his markers

what i want to do is to combine docking with RibbonView on one window

Overview of code:

<telerik:RadRibbonWindow>
<DockPanel>
<telerik:RadRibbonView DockPanel.Dock="Top" />
<telerik:RadDocking/>
</DockPanel>
</telerik:RadRibbonWindow>

All works perfect except the problem i described :

Compass, transparent overlays that shows where new panel will be docked and markers are translated to the right and bottom

Menu item disabling itself?

I have a main window that contains a RadMenu and a RadDocking.

When I select a menu item, I add a new RadPane to the RadDocking's RadPaneGroup. If I select the menu item multiple times, I get multiple RadPane's added, which is what I want.

The odd thing is that if I close one of the RadPanes, by clicking on its corner 'x' icon, the menu item disables itself. So once I close a pane, I can no longer open any more.

I can envision of no mechanism by which this could be happening, but happening it is.

I've created a stripped-down solution that demonstrates the problem. It works out to a 8.7MB zip file. I can't attach it here, should I email it to someone?
