Hi,

I am using silverlight 4.0 with telerik version  Q3 2009.In my application i used a telerik heirarchical grid.when wee add items to the Grid  it works fine.But when we try to save the data i am getting an exception in the App.xaml file.The error is related to the toggle button change in the heirarchical grid ,+ and minus.This is the exception message i am getting
 "Error HRESULT E_FAIL has been returned from a call to a COM component."

If anyone can find the solution with the same telerik version please help me to get solved.This is  the stack trace i am getting.If no dat is there in the grid it won't raise any exception.

Hi,

 Please use our official Silverlight 4 version instead - Q1 2010 SP1.

Kind regards,
