Hi guys,

I have a strange problem, I'm using the telerik wpf docking controls version 2012.3.1203.40 with VS2012 when my touchscreen is connected to my pc by USB (touchscreen: iiyama prolite T2250MTS) the RadDockingAutomationPeer throw an nullreference exception on loading.
If the touchscreen is not connected everything works just fine.

I tried to create a testproject for you, but the testproject throws an ArgumentNullException in the RadTabControlAutomationPeer, in this project I'm not using the RadTabControl.
And again if the touchscreen is not connected everything works fine.

The workaround is easy, just disconnect the touchscreen :-). For now this is my workaround, but it is no solution

Can you check it out?

How do I upload my test project?

David.

Hi David,

As the RadDocking uses internally TabControl, the exception occurs in the project, nevertheless it should be fixed in the Last Internal Build. You can downloaded from our website and give it a try.
Also in order to send us the simple project you have prepared you just need to open a new support ticket and attached the project in it.
As we are not aware of the issue with the RadDockingAutomationPeer it would be great if you can also give us a simple steps to reproduce.

Hi Georgi ,

I downloaded the latest version as you mentioned in your reply and upgraded my testproject

I have a lot less problems now, it seems to be working......

but when I set a debug exception on System.NullReferenceException it still throws an exception.


When I start the executable it does not show any errors.
