Hello,
I've tried a number of examples showing how to read the properties of a user
control from an aspx file where the code is on the html view of the form but
I can't figure out how to read them from the aspx.vb. Can anyone tell me
how to declare the user control in the aspx.vb file so that I can read the
properties?
I did add "Protected WithEvents UC1 As System.Web.UI.UserControl" to the
component code behind form but that's the only change I have made.
Many thanks,
Mike
Here's the example from dotnetjunkies I've been working with:

Inherits="UCSub" %>
<div align="center">
<table style="BORDER-RIGHT: 1px solid; BORDER-TOP: 1px solid; FONT: 10pt
verdana; BORDER-LEFT: 1px solid; BORDER-BOTTOM: 1px solid"
cellspacing="10">
<tr>
<td>
<asp:Label id="lblUserName" runat="server" Font-Bold="true" Text="User
Name:" />
</td>
<td>
<asp:TextBox id="txtUserName" runat="server" />
</td>
</tr>
<tr>
<td>
<asp:Label id="lblPassword" Font-Bold="True" Text="Password:"
runat="server" />
</td>

</td>

Got it.
Created a namespace around the user control class then added imports
[solution name].[namespace] and public [user control ID] as [user
control].ascx.vb to the aspx.vb. After declaring a public property with a
get end get in the ascx.vb I could refer to [user control ID].[property] in
the aspx.vb.
I found good information and the essence of this approach in examples at http://www.dotnetjohn.com/articles.aspx?articleid=52 and http://msdn.microsoft.com/library/de...properties.asp .
