asp.net gridview checkbox selection

Question

Need some help to solve this.

I have a gridview and inside the gridview I have a checkbox and after clicking the checkbox, I am doing a postback event and trying to

Answer 1

Try this:

CheckBox chkBx = sender as CheckBox;

Rather than iterate all the rows.

I haven't used CheckBox's in a GridView in this way myself. Usually I would use the GridView's OnRowCommand event instead and use the RowIndex or CommandArgument value to update the database.

Thinking about it OnRowcommand could be tricky for a CheckBox to fire, a better solution might be sticking with the CheckChanged event of the checkbox and navigate up to the GridViewRow serverside using controls NamingContainer. Something like:

GridViewRow row = chkBx.NamingContainer as GridViewRow;

I'm assuming the goes CheckBox => Cell => Row if you Google ASP.NET NamingContainer you'll get some more specifics.
