Call TemplateField DropDownList in asp.net - code behind with FindControl()

This is how i created my DropDownListLehrbeginn in my GridView. sss

<asp:TemplateField HeaderText="Lehrbeginn" SortExpression="lehrbeginn" HeaderStyle-Width="40px"> 
       <EditItemTemplate>
            <asp:DropDownList ID="DropDownListLehrbeginn" runat="server"></asp:DropDownList>
       </EditItemTemplate>
       <ItemTemplate>
            <asp:Label ID="LabelLehrbeginn" runat="server" Text='<%# Bind("lehrbeginn") %>'></asp:Label>
       </ItemTemplate>
</asp:TemplateField>

I want to add ListItems with c# like this:

DropDownListLehrbeginn.Items.Add(new ListItem(DateTime.Now.Year.ToString()));
DropDownListLehrbeginn.Items.Add(new ListItem(DateTime.Now.AddYears(1).Year.ToString()));
DropDownListLehrbeginn.Items.Add(new ListItem(DateTime.Now.AddYears(2).Year.ToString()));
DropDownListLehrbeginn.Items[1].Selected = true;

It doesnt work unfortunately. How can i fix this issue? DropDownListLehrbeginn is not available in code behind

Your code looks fine. Because your drop down list is within another element you probably just need to use something like this

DropDownList ddlList = (DropDownList)NameOfGridView.FindControl("DropDownListLehrbeginn");
