Button on_Click..?

[Kent Johnson]

Hi all,

I'm new to Asp.Net and I have a simple:

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As
System.EventArgs) Handles Button1.Click
TextBox1.Text = "This is a test"
End Sub

"This is a test" works in a Windows app. but not in Asp.Net web application.
If I push the button in a browser nothing happens. I have installed the Net
framework on the server.

What can be wrong?

You have to set the event handler at a different time. Usually in code
behind when the page is initialised with the OnInit event. VS.Net will
automatically generate a routine called InitializeComponent that simply just
assigned all the event handlers for the page, inlcluding the Page_Load
event, and then calls InitializeComponent from the OnInit event. In the code
you would have something like:
Button1.Click += new EventHandler(Button1_Click) (I'm using C# so the syntax
may be a little off).

If you're not using code behind, check out some of the examples of dealing
with events at:

Kent,

Are you sure that the Button control properties include the runat=server
property?

This is the property of the webcontrol that tells it to execute the code
that is placed in the codebehind area.... Otherwise it will never run the
code...

Don't know if you fixed it..

But couple of different things without knowing your
stuff. Button1 has to be declared in code behind and it
has to match the exact ID of your html or web control in
your html page.

The other is it Button1 in code behind has to be declared
using WITHEVENTS.

If you are using an image button you have to use a
different variable for eventargs.

Hope this helps
