public fields in webforms

All the fields in webforms are automatically declared as protected.
If I change them to public, they are converted back to protected.

Why is this happening ?

Thanks

Trebor,

The reason that's happening is that controls in your Webform cannot be
public. When you browse to a Webform, an instance of that class is
created. The request is served and a response is sent to the client. At
that point, the instance of your Webform is no longer accessible.
Therefore, it would be useless to have a public member of a Webform.
Protected is the correct access modifier.

I'm asking this question besause I found some articles on the web
which are recommending Server.Transfer for moving between forms.

Ex: // New public properties are defined in WebForm1:
public string TBText
{
get
{
return TextBox1.Text;
}
}
// Then on ButtonClick event, the other form is invoked

Server.Transfer ("WebForm2.aspx ");
----------------------------------------------------------

The destination form - WebForm2 is using code like this to access fields in
WebForm1.

WebForm1 Form1;
Form1 = (WebForm1) HTTP.Context.Ha ndler;
TextBox1.Text = Form1.TBText;

I was wonderig if I can avoid the step for creating public properties, by
declaring the fields in WebForm1 as public,
and then access their values in WebForm2 like:

Ex. 2

WebForm1 Form1;
Form1 = (WebForm1) HTTP.Context.Ha ndler;
TextBox1.Text = Form1.TextBox1. Text;
Is the approach in Ex1 Ok?

Is the approach in Ex2 Wrong and Why?

Thanks

Trebor,

You can't use method 1 because the variable will be out of scope. If you
want to use that method, you should declare the variable as a static
variable.
