How to Add UserControl Conditionally to Repeater Control?

Question

I want to know how to Add a UserControl Conditionally to a Repeater Control. I have tried to add it to the placeholder which is in Repeater Control but unable to load the usercontrol. This following code doesn't work.

<asp:Repeater ID="ResultsRepeater" runat="server">
        <HeaderTemplate></HeaderTemplate>
        <ItemTemplate>  
        <div>
            <asp:PlaceHolder ID="PlaceHolder1" runat="server">
            </asp:PlaceHolder>
        </div>
        </ItemTemplate>
</asp:Repeater>

 public void GetStatus(int i)
    {
        UserControl uc = new UserControl();
        if(i==1)
        {
            uc = LoadControl("DraftList.ascx") as UserControl;
        }
        else if(i==2)
        {
             uc = LoadControl("FinalList.ascx") as UserControl;
        }


        PlaceHolder p1 = (PlaceHolder)ResultsRepeater.Items[0].FindControl("PlaceHolder1");
        p1.Controls.Add(uc);

    }

Is there some reason that you don't want to just handle all of this in the aspx? That would be the simplest and cleanest option:

<asp:Repeater runat="server" ID="ResultsRepeater">
    <ItemTemplate>
        <uc1:DraftList ID="DraftList1" runat="server" Visible='<%# ((int)Eval("Status") == 1)%>' />
        <uc2:FinalList ID="FinalList1" runat="server" Visible='<%# ((int)Eval("Status") == 2)%>' />
    </ItemTemplate>
</asp:Repeater>

If a control is not visible, (i.e., Visible=false) then no markup is rendered, so coding in this fashion would not create any more work for the server or the client browser, while having the benefit of being much easier to read and providing user control properties at design-time.

You would just need to make sure to register your controls at the top of the page:

<%@ Register src="DraftList.ascx" tagname="DraftList" tagprefix="uc1" %>
<%@ Register src="FinalList.ascx" tagname="FinalList" tagprefix="uc2" %>
