Hi,
Here is a problem I posted before. The response I received was for VB but 
this code is c#.
<script runat="server" language="C#">
void Page_Load() {
	if(Request.Form["text1"] != null)
		Message1.Text = "You have entered the following name: " +
			Request.Form["text1"];
	if(Request.Form["text2"] != null)
		Message2.Text = "You have entered the following address: " 
+
			Request.Form["text2"];
	if(Request.Form["text3"] != null)
		Message3.Text = "You have entered the following 
password: " +
			Request.Form["text3"];
}
</script>
  This is from Beginning ASP.Net Using C# p.118 textboxpage.aspx. It seems 
to me that if you only enter data to one of the three text boxes then you 
should only see an asp label print that single line. Instead I get this if 
I only fill in the name in text1.

You have entered the following name: Gary Cook 
You have entered the following address: 
You have entered the following password:

  The only time it doesn't print these lines is the first time it runs. 
After that I get the design time text with no user input even if I enter 
nothing? Thanks for any advice. 
 

gary,

In your if....then structures try replacing 'null' with "". This might sound
strange, but it might be worth a try.

PS. I do VB not C#, but its worth a try !

Sam

These books look at how we can create data-centric ASP.NET

Hi Gary,

Another thought, you could set the visible property of the controls to false
at page_Load, then if the text property of your message(n) controls is other
than an empty string, turn the visible property on.

Hi Sam,
  This is the same answer you gave before. It gives even worse results. 
Thanks anyway.

Gary

Hi Sam,

       if(Request.Form["text1"] != null && Request.Form["text1"] != "")

  This seems to work as well as anything will. Once you do enter something 
into a text box asp on the server seems to remember it and sends it as a 
message even if the specific text box is now empty.

  The null part catches it the first time it runs and the "" part catches 
it when you press the submitt button. Using submit seems to send an empty 
system string as I found out using - Request.Form["text2"].GetType()
