RadGrid + column rezsize error

[Tomasz]

Hi ,

 I want to ask about the following RadGrid problem : when I resize the column using mouse 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.
 or

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

offten with this , the old lines of column border are staing and displayed 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

Hi Tomasz,

This error indicates that a handler is trying to be attached to a javascript event but it failed. Unfortunately it is not clear what might be the reason for this. Could you please post some markup form the RadGrid control and the related code behind. Also please verify whether you have any client-side scripts that can cause this error, and especially if you attach event handlers client-side.


Best wishes,
