I have a GridView that I'm trying to implement a Confirm OnDelete.
The below code works except that I'm getting the error "Specified
argument was out of the range of valid values. Parameter name: index"
when ever I click Update. I know that this is happening because there
are no controls now in that cell. What condition can I test against?

Thanks


/////////////////CODE/////////////////////

<asp:GridView ID="SOCCatGridView" runat="server" AllowPaging="True"
AllowSorting="True"
AutoGenerateColumns="False" DataKeyNames="ssoccID"

/////////////// C# Code //////////////
protected void DetailGridView_RowDataBound(object sender,
GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{

LinkButton db = (LinkButton)e.Row.Cells[0].Controls[1];
db.OnClientClick = string.Format("return confirm('Are you
certain you want to delete this record?');");

}
}
