string rolename = string.Empty;
GridView gvRoles = ((GridView)DataList1.FindControl("GridView1"));
gvRoles.DataBind();
foreach (GridViewRow gvrow in gvRoles.Rows)
{
CheckBox chk = (CheckBox)gvrow.FindControl("chkRole");
Label lbl = (Label)gvrow.FindControl("lblRole");
rolename = lbl.Text;
int index = Array.I ...
