Hi, I have a grid in an update panel. When the page opens the first time, the grid shows data without any errors. The grid refreshes when the user clicks on a command button, and I get this error.

I have attached a snippet of the page source where it is erring. The highlighted line is where the error occurs.

Thanks

Ram
