Hello Juergen Holzer,
Thank you for writing.
It look like the null reference exception is an issue in the CreatingListVisualItem
event. It appears that the VisualItem
argument is always null. We will address this issue on one of the next releases. For the time being I suggest you to consider the implementation with MouseDoubleClick
provided before in this topic.
I have updated your Telerik points for bringing this issue to our attention. Let me know if you have any other questions.

Q1’11 SP1 of RadControls for WinForms is available for download
; also available is the Q2'11 Roadmap
for Telerik Windows Forms controls.
