Hi,
  I'm reviewing try it out <aspx:textbox> control in Ch.3 p.118 
of "Beginninbg ASP.NET".
  If I run it as written in the book with this if statement:
     if(Request.Form["text1"] != "")
     {
         Message1.Text = "You have entered the following name: " +
                   Request.Form["text1"];
     }
the result is that the first time the page is accessed the string portion 
of Message1 as well as for the other two messages are writen in the 
response.
  So I changed it to if(Request.Form["test1"] != null) . This worked 
better. The first iteration showed no message in the response, just the 3 
text boxes. It works fine if I enter data to all the text boxes.
  I still have a problem though as if I enter data into only one of the 
three text boxes the response writes the appropriate message and the input 
data, but it also writes the not required message, for example the "You 
have entered the following address: ", but with no data.
   I seems to me that the following code which I am using should only 
write a message for a textbox if there has been data entered into that 
control specifically, not the others.
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"];
	} 
}
 
Thank you for any advice.

Hi There Gary,

For inequality have you considered using 

		If text1.Text <> "" Then
			......Your conditional code.......
		End If

Regards

Sam
