How do I find the Client ID of control within an ASP.NET GridView?

Question

I have a asp:GridView which contains a asp:TextBox within a TemplateField. I would like to obtain it\'s ID for use in javascript. Something like this:

Answer 1

I just do this...

var tbl = document.getElementById('<%=GridView.ClientID%>');
var checkBox = tbl.rows[i].cells[11].getElementsByTagName("input")[0].id;

the cell should always be the same and it gets rendered into an input. You may have to change the number at the end if you have more then one input in that cell. This will give you the new clientid/id of the input object (checkbox or whatever)
