problems with my UserControl

[Magnus Pesch]

Sorry,

I thought i would be in an german NG. I will try to translate...

i have made a UserControl (later there should be some controls in it) as
ascx-file (in Visual Studio 2003) and i am loading it in a normal WebForm.
In this UserControl should be properties (and later functions) which should
be changed (called) in the WebForm.

When I open the WebForm anythinf is ok.

But when i want to change the property (when the WebForm is already loaded)
and a PostBack is made, there is no change in the control from the
UserControl.Why? What can i do?

At the bottom there is my coding - there i used the property just for the
Text in a TextBox.

It would be nice, if anyone can help me with this. Maybe i must implement
IPostBackEventHandler...? How does this work?

Greetings from Germany, Magnus


My Coding:

*** CodeBehind UserControl

Public Class TestControl

Inherits System.Web.UI.UserControl

Private Text As String

Public Sub New()

Text = "nicht gesetzt"

End Sub

Public Sub New(ByVal Bezeichnung)

Text = Bezeichnung

End Sub

Public Property Bezeichnung() As String

Return Text

End Get

Set(ByVal Value As String)

Text = Value

End Set

End Property

Protected Overrides Sub OnPreRender(ByVal e As System.EventArgs)

TextBoxControl.Text = Text

End Class


*** Ende UserControl



*** Call in WebForm

Public Class WebForm1

Inherits System.Web.UI.Page

Dim c1 As UserControl = LoadControl("TestControl.ascx")

Private Sub Page_Load(ByVal sender As System.Object, ByVal e As

System.EventArgs) Handles MyBase.Load

Dim c1 as UserControl = LoadControl("TestControl.ascx")

CType(c1, TestControl).Bezeichnung = "jetzt Text definiert"

End Sub

Private Sub Button2_Click(ByVal sender As Object, ByVal e As

System.EventArgs) Handles Button2.Click

CType(c1, TestControl).Bezeichnung = "Text geändert"
