Object reference not set to an instance of an object

[Ben]

Hi,

I want to access in code-behind a label within the ItemTemplate of a
Formview.

<asp:FormView ID="FormView1" runat="server" DataKeyNames="id"
DataSourceID="SqlDataSource1" >
<ItemTemplate>
<asp:Label ID="nameLabel" runat="server" Text='<%# Bind("name")
%>'></asp:Label>

code-behind:
Dim name As String = CType(FormView1.FindControl("nameLabel"), Label).Text


I get the error: "Object reference not set to an instance of an object"

Could somebody tell me what's wrong in my code?
Thanks
Ben

As a general rule, it's a good idea to break up the statements in a single
line multi-expression code line into their own lines of code to facilitate
setting breakpoints and being able to examine values. The way you have it
now, it would be extremely difficult to tell what is going on.
