User Control - setting properties

J

John Carnahan

Don't quite get it.

User control has a label in a html table and I want to set the text property
of the label from code behind. (MyLabel)

<%@ Register TagPrefix="MCP" TagName="TOPMENU" src="TopMenu.ascx" %>
<HTML>



FORM....
<MCP:TOPMENU id="TopMenu1" runat="server"></MCP:TOPMENU>


CODE BEHIND...PAGE LOAD

??? MyLabel.Text="Something"

Can't see the label object in the code behind... Why not? How do I get to
it?

John, give the User Control a public string property, like MyLabelText.
Then in the Page_Load event of the User Control, set its Label's Text
property to the value of the MyLabelText property. In the ASP.NET Web
page's code behind class, set the User Control's MyLabelText like so:

TopMenu1.MyLabelText = "Foo"

(You'll need to have manually added in a reference to TopMenu1 in your
class, like:

Protected TopMenu1 as TopMenu
)
