I have a datagrid and it has a dropdownlist which is named

<asp:DropDownList Runat=server ID="CIdeefixeSatis" SelectedIndex='<%#
SelectMyIndex(DataBinder.Eval(Container, "DataItem.ideefixesatis"))

In my SelectMyIndex Function

Dim ideefixesatisc As DropDownList

ideefixesatisc = CType(Page.FindControl("CIdeefixeSatis"), DropDownList)

There is no problem till that line but when i add

ideefixesatisc.DataTextField = "Stokta Var"

ideefixesatisc.SelectedIndex =
ideefixesatisc.Items.IndexOf(ideefixesatisc.Items.FindByValue("True"))

It returns

Line 53: ideefixesatisc.DataTextField = "Stokta Yok"
