Drag Drop Item on Treeview not working in IE but works in FF

[Thomas LEBRUN]

Hi,

Using the latest version, when I tried to drag/drop an item in my Treeview, i get the following error in IE:

The value is not within the expected range.

With the following stacktrace:

   à MS.Internal.XcpImports.CheckHResult(UInt32 hr)
   à MS.Internal.XcpImports.SetValue(INativeCoreTypeWrapper obj, DependencyProperty property, Double d)
   à System.Windows.DependencyObject.SetValue(DependencyProperty property, Double d)
   à System.Windows.FrameworkElement.set_Width(Double value)
   à Telerik.Windows.Controls.RadTreeView.ShowBetweenItemsDragCue(RadTreeViewItem dropDestination)

   à MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, String eventName)


Using Firefox, it works fine !

Any ideas ? This is quite urgent because the project will be tested ASAP.....


Thanks !

Hi Thomas,

This is a very strange error you are experiencing. I wasn't able to reproduce the issue you are describing. Could you please provide us with more information about your scenario, because the current information is not sufficient to determine what exactly causes the problem. Additionally, it would be great if you can open a support ticket and attach a sample project reproducing the issue.

Hi Kiril,

I'm not able to send you a sample project because I'm working on a big project but it looks like the bug is not here when I deploy the application on the Web Server but that it happened when I run the application on my machine....

Well, I need to look at the more in details later, sorry for disturbing....
