Transfer data between pages

Expand Post »

Hi,

I have been trying to transfer some data from one page to another but nothing seems to work. Data is not being passed to the next page. Can anyone tell me a reason why this could happen?

Re: Transfer data between pages

If you are using the .net framework 2.0 or greater, you may want to look at the PreviousPage property of the Page object.

For example, let's say you have a hidden field in your original page named hfTheHiddenField and want its value when you get the target page. You can do something like this...

c# Syntax (Toggle Plain Text)
Control ctrl;
string theString;
ctrl = PreviousPage.FindControl("hfTheHiddenField");
if(ctrl != null) {
  //cast it and get it's string value.
  theString.Value = ((HiddenField)ctrl).Value.ToString(); 
}
Control ctrl;
string theString;
ctrl = PreviousPage.FindControl("hfTheHiddenField");
if(ctrl != null) {
  //cast it and get it's string value.
  theString.Value = ((HiddenField)ctrl).Value.ToString(); 
}

You could also use Server.Transfer or the Request.Response objects to get values from previous pages as well.

Re: Transfer data between pages

or use a session variable ?

ASP.NET Syntax (Toggle Plain Text)
Session("session_name") = DATA
Session("session_name") = DATA

then get it back wherever you wish by using

ASP.NET Syntax (Toggle Plain Text)
Session("session_name").value()
Session("session_name").value()

then free up memory and

ASP.NET Syntax (Toggle Plain Text)
Session.remove("session_name")
Session.remove("session_name")

(SYNTAX VB.NET)
