Accessing Gridview Cell Values from inside a Template column

I have a checkbox inside a template field of a gridview, and I need it to respond to a click by appending the key value of the row to a sql statement and executing it.  I have tried using

dim ID as string = MyGrid.SelectedValue.ToString

in the checkbox's OnClick event, but evidently, SelectedValue is populated only if a row is selected using the built-in "Select" button.

I have been advised to add a custom attribute to the checkbox in the GridView's RowDataBound event.  In this context, I can get the value I need in GridView.DataKeys(e.Row.RowIndex).Value.ToString, but I can find no way to add the attribute to the checkbox.

Basically, I need to know how to access the cell values, including the key value, of a Gridview row when a control inside a template field is clicked.

Thanks for your advice.

I'm in the same situation. Here's what I plan on doing (haven't actually implemented it yet).

Protected Sub CheckBox1_CheckedChanged(ByVal sender As Object, ByVal e As System.EventArgs)
   Dim cb As CheckBox = CType(sender, CheckBox)
   Dim row As GridViewRow = CType(cb.Parent.Parent, GridViewRow)
   ' I think you can figure the rest out from here

How to access GridView hidden Column value by clicking a template column button?
Hi: My GridView contains(for simplicity sake) three columns: a hiden template column that contains the DocID (the DataKey), a template column that contains DocTitle and a template button column that contains a button called btnDetails. When the GridView is loaded with data, the user may click the button on a row and obtain the DocID from the hidden column of that row. This seems to be simple enough. However, when the button is clicked, the GridView always returns blank. Any idea why this happens? My code is as follows: ASPX <asp:GridView ID="gvList" runat=&...
