CrossPagePostBack

Please! Need Help!

I have two pages as followed

1. Loading.aspx (contain a TextBox1 and a Button1.)

2. PrintL.aspx (contain a TextBox2)

Both pages has the same MasterPage.master

When click Button1 on Loading.aspx page, it will PostBackUrl to PrintL.aspx

The question is how can I pass a value from TextBox1 to TextBox2

I try using this but it doesn't work

(code in PrintL.aspx)

TextBox SourceText = (TextBox)Page.PreviousPage.FindControl("TextBox1");

TextBox2.Text = SourceText.Text;

However it works fine if Loading.aspx doesn't have a master page. Why

Thank you.

I know this discussion is old, but for anyone with a similar question, here is the answer as I understand it.

You can only reference controls on the current page directly. If you are doing a CrossPagePostBack, use the PreviousPage object to reference controls on that page. Otherwise, you can write the values to the Session object and read them at the target page. It's a good idea to remove session values as soon as you are done with them so you don't inadvertently follow the wrong code path on a PostBack.

I am experiencing a seemingly similar problem:

Page1.aspx (contains hidden fields field1 and field2)

Page2.aspx (trying to read the values of field1 and field2)

When I perform a cross-page post from Page1 to Page2 and attempt to read the values of field1 and field to as follows:

Label1.Text = Request.Form("field1")

Label2.Text = Request.Form("field2")

I get empty values in the labels.

Any ideas
