P.S. Noticed the javascript variable names. a=b.id? Who are you? A market leading company? I used to have such variable names when I was 12... Shame.

Hello Johny,

 The error indicates that some HTML element (probably the expand-collapse button) is null at this time. From the screenshot it is not clear what might have caused this problem. Can you specify how you have databound the grid and whether you have any other client-side code executed at this time? A sample code that replicates the issue will be helpful in determining the exact cause of the problem.
Also the code that you see in Firebug is a result of the javascript minification process. A common practice used to decrease the size of the client-side resources for optimization purposes.

All the best,
