Scott,



I can tell you that this can be done. Not being that fluent in C#, I have

been unable to successfully translate my VB example. Maybe you (or someone

else) can translate it =). Some of this code came from an example at

aspfree.com. Here is the code I use to achieve this kind of dynamic

functionality:



----- uctest.aspx --------

<%@ Page Language="VB" %>

<%@ Import Namespace="System.Reflection" %>



<script language="VB" runat="server">

    Public Sub Page_Load(Src As Object, E As EventArgs)

    'Load the control

    Dim myUC as UserControl = LoadControl("ucContent.ascx")



    'Set the Usercontrol Type

    Dim ucType as Type = myUC.GetType()



    'Get access to the property

    Dim ucDefualtSidProperty as PropertyInfo 

ucType.GetProperty("DefualtSid")



    ' Set the property

    ucDefualtSidProperty.SetValue(myUC,1,Nothing)



    pnlTest.Controls.Add ( myUC )

End Sub

</script>

<asp:panel id="pnlTest" runat="server" />



------ ucContent.ascx --------

<script language="VB" runat="server">

    Private _DefualtSid as Integer = 0



    Public Property DefualtSid As Integer

    Get

    Return _DefualtSid

    End Get



    Set

    _DefualtSid = value

    End Set



    End Property

</script>

<h1><%=_DefualtSid%></h1>
