LoadLayout => ArgumentOutOfRangeException

[Michel]

Hi,

I have an exception when I load a layout containing a radpane as a user control. The exception is:

{System.ArgumentOutOfRangeException: L'argument spécifié n'était pas dans les limites de la plage de valeurs valides.
Nom du paramètre : elementTypeName
   à Telerik.Windows.Controls.Docking.DockingLayoutFactory.GetElementByTypeName(IGeneratedItemsFactory factory, String elementTypeName)

   à MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName, UInt32 flags)}

Does the load layout support radpane as user control?

This my code :

Hello Michel,

Currently custom elements can not be loaded using the save/load layout logic. We have it logged here in our Public Issue Tracking System. As a workaround you can either edit the XML or the class of the Pane in and make sure the Pane is saved as a RadPane in order to be recognized by the load logic. 
Hope this will help.

Greetings,

Can you post a link to the specific bug in the bugtracker, I am not able to find it, and i would like to upvote it.

Hello Theo,

The link for the PITS issue is http://www.telerik.com/support/pits.aspx#/public/silverlight/12105 .
You can also access it by going to http://www.telerik.com/support/pits.aspx#/main/Release=AllReleases/Product=silverlight and search for " Save custom elements with the correct names " (you may need IE).
Also if you have any other questions, please don't hesitate to write us.
