FindControl() returns null some times in ItemDataBound and Edit events

[jgbeldock]

I have seen the following behavior: when issuing a Page.FindControl() for a
control which exists in an item template (from within an ItemDataBound()
event, for example), I get nulls back regularly. Has anyone seen this
before? It's pretty aggravating to have to iterate through the controls in
each grid cell to find the ones I need, especially since finding those cells
is not always easy. Here's my Edit() handler (but it gives the same errors in an ItemDataBound() handler):

private void streetAddressGrid_EditCommand(object source,
System.Web.UI.WebControls.DataGridCommandEventArgs e)
{
streetAddressGrid.EditItemIndex = e.Item.ItemIndex;
streetAddressGrid.DataBind();
DB.DbStreet_Address sa = new DB.DbStreet_Address();
sa.Street_Address_ID=
(SqlInt32)System.Convert.ToInt32((e.Item.Cells[0].Controls[1] as
Label).Text);
sa.SelectOne();

// exceptions begin here; even though these controls exist, FindControl()
returns null
(e.Item.FindControl("line_1&quot as TextBox).Text = sa.Line_1.ToString();
(e.Item.FindControl("line_2&quot as TextBox).Text = sa.Line_2.ToString();
(e.Item.FindControl("line_3&quot as TextBox).Text = sa.Line_3.ToString();
(e.Item.FindControl("city&quot as TextBox).Text = sa.City.ToString();
(e.Item.FindControl("state&quot as TextBox).Text = sa.State.ToString();
(e.Item.FindControl("postal_code&quot as TextBox).Text =
sa.Postal_Code.ToString();
(e.Item.FindControl("country&quot as TextBox).Text = sa.Country.ToString();
}

Any thoughts would be appreciated!

Thanks,

you can wrap the works in this...
if (e.Item.ItemType == ListItemType.EditItem)
{
your code
}

and ListItemType.Item for your not working with the edit

HTH.
