I have a web form which contains a user control. I need to be able to
set a variable value in the web form and read it from the user control.
I’m using VB.NET.
How should I do this? It seems one can’t just read the variables set by
the other.
Many thanks,
Matt

Thanks for the reply. I haven't used the Set command before.
Do you mean that if I *Set* a value in the parent page I can read the value
in the user control normally?
Is this code correct?
Set(ByVal Value As String)
concertids = Value
End Set
Thanks,
Matt

Hi,
Here is some quick syntax.
its something like this (from within the usercontrol)
C#
System.Web.UI.Page CallingPage;
CallingPage = (System.Web.UI.Page)this.Page
but at work we have every Page derive from a basepage, so we go
OurProjectName.BasePage CallingPage;
CallingPage = (OurProjectName.BasePage)this.Page
CallingPage.WhateverMethod(); //Whatever method found on the base page.
You may want to use an interface in your case... I'm not sure if VB
supports those. but... C# it would be something like
public interface myInterface
{
public void FillTextBox(string text);
}
-------------
Then your page implement the interface
public class yourpagewithusercontrol : myInterface
{
public void FillTextBox(string text)
{
someTextBox.Text=text;
}
}
then in your user control you go
myInterface m;
m = (myInterface)this.Page;
m.FillTextBox(somevalue);
I really should be providing some code examples but I'm just heading out
the door for work!
Let me know if you need a better explanation.
