aspx thread: Really simple C# question-- setting the Text property of a label.
Message #1 by "Oliver, Wells" <WOliver@l...> on Thu, 5 Sep 2002 08:35:27 -0700

Trying to make a transition from VB.NET to C# and I'm unable to do this
really simple thing (which is of course probably not a good sign, but...).
Consider--
apsx:
<%@page language="C#" inherits="testPage" src="test.aspx.cs"%>
...
<asp:label id="testLabel" runat="server" />
aspx.cs:
using System;
using System.Web.UI.WebControls;
public class testPage : System.Web.UI.Page
{
public Label testLabel;
private void page_load (Object Sender, EventArgs E)
{
testLabel.Text = "Test";
}
}
However, the "testLabel" is still blank.
Help? :)

Did you recompile after you added the "testLabel.Text = "Test";" code?
The syntax to looks good to me.

Hello Oliver,
you know that c# is case sensitive? In your case this means
that the page load event should read Page_Load. Also is
the Page_Load event registered during your OnInit event?
This is normally done by the designer, but if you did not
use the designer and wrote your code manually you also have
to register the event handler.
w> private void page_load (Object Sender, EventArgs E)
^^^^^^^^^^^
w> {
w> testLabel.Text = "Test";
w> }
w> }
w>
w> However, the "testLabel" is still blank.

Thanks for the advice.
I rewrote it as "Page_Load" (have to keep the case sensitivity in mind; I
think it's definitely a good trait of a programming language). However, it
seems to work without the OnInit handler being written.
Why would this be? Does it have anything to do with the AutoEventWireUp
directive? I do not have that set to true or false in my page, and I think
it's false by default.
Thanks.

hmmm, that's strange. Normally this should not work. Did you
have a look at the designer generated code region in your
code behind file? The event registration takes place there.
Actually i do not know the meaning of the AutoEventWireUp
directive. I know that there is this directive, but i
never changed the default value. Take a look in the
help for this.

Yeah, I am not using VS.NET so there is no generated code (just a straight
text editor). I have no OnInit handler, either.
Curious, eh. Hey, if it works, it works, right? :)

There is no need for the OnInit EventHandler if u don't have
code-behind... Page_Load is default
