When clicking on a row or expanding rows in the rad treelistview, the following unhandled exception occurs, and it happens intermittently. The full error is attached to this thread, but the first few lines are as follows

An error occurred: Parent grid cannot be null
Parameter name: parentGridViewDataControlPeer

Please view the log for more details
System.ArgumentNullException: Parent grid cannot be null
Parameter name: parentGridViewDataControlPeer

Hi,

 Please post more info about your grid version. I had such problems in the past however we believe that these were fixed.

Sincerely yours,

Hi Vlad

We are using version 2010.2.812.35 of the Telerik.Windows.Controls.GridView control. Do we need a later version?
