I’m using the rowdragdrop example inside of a viewbox. Theviewbox is set to stretch=”Fill”. The problem I’m having is that when the userresizes the window and moves a row the offset inside the viewbox isn’t changingwhich means the position of the row that I’m dragging isn’t under the mouse.
I was wondering if you had any ideas on how this could befixed?
Thanks

Hello,
I want to perform my own custom logic whenever an item is dragged/dropped. This procedure requires me to access the item's parent. I noticed that when I drag items and then drop them, in the RadTreeView.DragEnded event, the item's ParentItem property becomes null and the FullPath string property is also cleared.
Is this the correct event to handle for my custom logic (i.e. performing the "drop" in the business logic)? If so, how can I get the item's parent before it was dragged (i.e. its current parent).
Thank you.

Hi There
We are shift to Q3 Controls but my MouseLeftButtonDown on GridView doesn't fire. As i have seen the post where this event handle by mouse class of Telerik.Windows.Input namespace but we are not able to find this namespace, there may be version issue. We use assemblies with version [2009.3.1103.35]. Please reply me as soon as possible. and if possible submit a demo.

Hello,
I'm using the GridView/HeaderContextMenu example for version 2009.3.1208.35. When i have more columns than displayed on the screen it seems to mix up the contextmenus. Also this line of code IEnumerable<GridViewHeaderCell> cells = row.Cells.OfType<GridViewHeaderCell>(); in the InitializeMenus method doesn't return all of the GridViewHeaderCells.
made a quick example,
on my machine if you scroll to the right an open the contextmenu for column Test17 it opens up the contextmenu for Test3.
Any help would be great.
Thanks Again,
~Boots

Hello,
I am appending an entry to a grid that contains several hundred items. I use ScrollIntoView to scroll the grid to where the item was added but I have not figured out how to hi-light (select) the new entry. The example at this site on how to do this uses constructs that are no longer supported by the latest release. The grid has the SelectAll and UnSelectAll commands so there has to be some command that selects only one row.
Any help would be appreciated.
Thanks

Hi all,
We are testing to buy the library. For this we did a nice prototype in Silverlight to test RadControl.
Now i'm converting the silverlight prototype to WPF to see how the RadControl lib behaves since we have to choose a lib which is 100% compatible with silverlight and WPF. We don't want to wonder each time we do something in silverlight if it is potential broken on WPF.
Currently I'm facing a problem with RadControl and the WPF version of our prototype. Visual Studio saying it can't find reference to some RadControl component.
RadDockPanel
RadDockPanel.Dock
HierarchicalDataTemplate
It logs Erreur 2 Erreur de génération inconnue, 'MC3074 : la balise 'HierarchicalDataTemplate' n'existe pas dans l'espace de noms XML 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls'. Ligne 16 Position 10.'
Erreur 3 Erreur de génération inconnue, 'MC3074 : la balise 'RadDockPanel' n'existe pas dans l'espace de noms XML 'clr-namespace:Telerik.Windows.Controls;assembly=Telerik.Windows.Controls'. Ligne 32 Position 10.'
Erreur 4 Le type 'telerik:RadDockPanel' est introuvable. Assurez-vous qu'il ne manque aucune référence d'assembly et que tous les assemblys référencés ont été générés.
I've well added references with all Telerik's references availables.
So my question is why it does not found this telerik components in WPF version?
This raises 2 important questions
1) Do all the Telerik's components available in silverlight are available in WPF ?
2) Do all the Telerik's components have the same naming in both SDK ?
Thank you by advance for your support.

Hi,
I'm trying to change the theme of a RadWindow from C# but couldn't get it to work. This is my code:
XAML:
<telerikNavigation:RadWindow

C# (Button click event):
StyleManager.SetTheme(this.winMainWindow, new VistaTheme());
Note that the RadWindow is the root element, and my code behind class is inheriting from RadWindow as follow:
public partial class MainWindow : RadWindow
