DataGridItem.FindControl doesnt find the control? (ASP.NET)

Label lbl = dgi.FindControl("LBL_MyLabel") as Label;

This works most of the time, but sometimes lbl is null after FindControl was called. I am wondering how this could happen. It should either be there or not? Any ideas?

The label is defined like this:

<asp:Label ID="LBL_MyLabel" runat="server"></asp:Label>

Thanks :-)

What's the broader context of the code around the call to FindControl? This error is commonly experienced when iterating through the rows in the grid (such as in the RowDataBound event) without conditionally checking what the row type is:

if (e.row.RowType == DataControlRowType.DataRow)
{
  // your code
}

Wrapping it in that conditional will skip header/footer rows, which probably don't have your label control in them.
