How to expose server control properties from a Web User Control?

[Todd W]

I have a dilemma. I created an ASP.Net Web User Control with an asp:label
on it. Then I dragged that control onto an .aspx web form. What I need
to do is to write code in my ASPX code behind that allows me to SET the label's
text property at runtime. In all the examples I am finding, it appears that
the server control's within a User Control can only be set from code WITHIN
the user control itself.

Does anyone know how to expose the text property of the label in the User
Control in such a way that the ASPX page it resides on can set the text property?
A simple example would be that when the client types in a value in a textbox
on the web page and then clicks a button, the Label on the User Control has
its text property set to the text in the text box.

Thanks in advance,

Todd

To expose the text property, put the following code (VB) in the user control:

Public MustInherit Class UserLabel
Inherits System.Web.UI.UserControl
Protected WithEvents Label1 As System.Web.UI.WebControls.Label

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
Label1.Text = _Text
End Sub

Private _Text As String = "user control label"

Public Property Text() As String
Get
Return _Text
End Get

Set(ByVal Value As String)
_Text = Value
End Set
End Property

Then, assuming you register the user control on the Web page as follows:

<%@ Register tagprefix="sma" tagname="userlabel" Src="UserLabel.ascx"%>

In the ASPX page load, put the following code:

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles MyBase.Load
'Put user code to initialize the page here
Dim oUserLabel As UserLabel = Me.FindControl("smaUserLabel")
oUserLabel.Text = TextBox1.Text
End Sub
