Answer 1

this.DataGrid1.ItemDataBound += new System.Web.UI.WebControls.DataGridItemEventHandler(this.DataGrid1_ItemDataBound);private void DataGrid1_ItemDataBound(object sender,DataGridItemEventArgs args)
{
if(args.Item.ItemType == ListItemType.EditItem)
{
DropDownList DropGroupID1 = (DropDownList)args.Item.FindControl("DropGroupID");
if(DropGroupID1 != null)
{
SqlConnection conn = new SqlConnection(Global.ConnectionString);
conn.Open();
SqlCommand cmd = new SqlCommand("select tmpUID,tmpName from tmpFlag",conn);
SqlDataAdapter da = new SqlDataAdapter(cmd);
SqlDataReader dr = cmd.ExecuteReader(CommandBehavior.CloseConnection);

DropGroupID1.DataSource = dr;
DropGroupID1.DataValueField = "tmpUID";
DropGroupID1.DataTextField = "tmpName";
DropGroupID1.DataBind();
dr.Close();
string asdd= ((Label)args.Item.FindControl("Label1")).Text;
DropGroupID1.Items.FindByValue(asdd).Selected = true;
}
}
}
