[sharath]

Hello Team,

I want to add the checkbox to the gridview. Here the gridview is the user control. I tired to add the checkbox as usual for the grid. But it was showing the error. Am i I missing anything while adding. 

This is my user control.ascx code. I have not added the checkbox. Please suggest me where to add. I used the <asp: checkbox....</asp>. This method gave the error.
