LoginView.FindControl not finding control

ChadThiele — Wed, 29 Nov 2006 01:07:52 GMT

I'm trying to bind data to a repeater. The repeater is inside a loginView control. Like so:

            <asp:loginview id="loginView" runat="server">
                <anonymoustemplate>

                    <asp:repeater id="rpLessons" runat="server">

                        <itemtemplate>
                            <div>
                                <a href="Default.aspx?lid=<%# Eval("PodID") %>"><%# Eval("Name") %></a><%#Eval("Duration")%>
                            </div>
                        </itemtemplate>
                    </asp:repeater>

                </anonymoustemplate>
            </asp:loginview>

I'm binding data to it like so:

1    Repeater rpLessons = (Repeater)loginView.FindControl("rpLessons");
2    rpLessons.DataSource = Lessons();
3    rpLessons.DataBind();

With the Lessons method looking like this:

1    private List Lessons()
2    {
3    	List lessons = new List();
4    	lessons.Add(new Lesson(1, "Once Upon a Time", 9));
5    	lessons.Add(new Lesson(2, "On Another Note", 7));
6    
7    	return lessons;
8    }

And the Lesson class looks like:

1    public class Lesson
2    {
3    	public Lesson(int podID, string name, decimal duration)
4    	{
5    		this._podID = podID;
6    		this._name = name;
7    		this._duration = duration;
8    	}
9    
10   	private string _name;
11   
12   	public string Name
13   	{
14   		get { return _name; }
15   		set { _name = value; }
16   	}
17   
18   	private int _podID;
19   
20   	public int PodID
21   	{
22   		get { return _podID; }
23   		set { _podID = value; }
24   	}
25   
26   	private decimal _duration;
27   
28   	public decimal Duration
29   	{
30   		get { return _duration; }
31   		set { _duration = value; }
32   	}
33   
34   }

But, I'm getting an error: Object reference not set to an instance of an object for line 2 [ rpLessons.DataSource = Lessons(); ]

Apparently the FindControl method of the LoginView control isn't actually finding the control. Any ideas why not?
