Custom UserControl Custom Properties After You Add Programatically

[Daniel Friend]

Hello,

I have added a custom usercontrol programically and all works fine... I
would like to change some custom properties that I have set in that
usercontrol.

Any help would be greatly appreciated!!!!

Here is a sample of What I am doing:

Private Function ClassByControl(ByVal strAssemblyFileName As String) As
UserControl
Dim objAssembly As [Assembly] = [Assembly].LoadFrom(strAssemblyFileName)
Dim cControl As UserControl
Try
cControl = objAssembly.CreateInstance("Sample.UserControl1")
cControl.UserName="XXXXX"
Catch
End Try
End Function

In the Control I have the Following Propert Set:

Public Property Username() As String
Get
Return ssUsername
End Get
Set(ByVal Value As String)
ssUsername = Value
End Set
End Property

There error happens on cControl.UserName="XXXXX"

Thanks,

Dan
