findcontrol

I want to switch font colours depending on a value - this code works great when the form loads but errors on the lbl.ForeColor = Drawing.Color.Red
when I try to update - it doesn't seem to find the label

Protected Sub GridView3_RowCreated(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView3.RowCreated

If e.Row.RowType = DataControlRowType.DataRow Then
Dim lbl As Label = CType(e.Row.FindControl("Label1"), Label)

If DataBinder.Eval(e.Row.DataItem, "Over_Under") < 0D Then
lbl.ForeColor = Drawing.Color.Red
Else
lbl.ForeColor = Drawing.Color.Blue
End If
End If

End Sub

When you are updating, are you not in the EditItem mode? does that label exist for that row at that point?

if not... change that statement to include if rowtype is not edited.... with a datagrid its like

if not e.Item.ItemType = listItemType.EditItem then
....

not sure about gridview.

excellent point - it's label3 in edit mode.
