[Tomasz]

Hi ,
I want to ask about the following RadGrid problem : when I resize the Gridcolumn usinig in my application I get the one of the following errors

 

Error: Sys.InvalidOperationException: Handler was not added through the Sys.UI.DomEvent.addHandler method. 
and often when i try once again after it 

 

Error: 'this.ColGroup.Cols' is null or not an object

offten with this , the lines of  the resized column border are staing and displayed in old place in grid, the grid is binded with ajax.

Part of ClientSettings bibded with resize look like this

 

 

 

 

 

<ClientSettings EnablePostBackOnRowClick ="True">
<Resizing AllowColumnResize="True" />

 

It's a very big problem for me, It occurs in both ie versions - ie 8 and ie 9,
can anbody help me with this?
Regards,
Tomek
