Hello guys.

I have a grid with one GridButtonColumn. If I use Buttontype="LinkButton" or "PushButton", it work's fine, but if I use Buttontype="ImageButton" I have the error showed in atach, when button is clicked.

It's a bug?

Regards.

Hello Silvio,

This error usually appears if you rebind RadGrid on every Page_Load. Could you please let us know if this is the case?

Hello Daniel.

Our case is not this that you mentioned. We don't have grid rebind in Page_Load.

If I only change the Buttontype to "LinkButton" instead a "ImageButton", I have no problems anymore.

Some suggestion?

Thanks.

Regards.

Hello Silvio,

Another reason could be that you have disabled the viewstate - it is hard to guess the exact problem this way - can you please post/attach your code so I can examine it?
