ASP2 PostbackURL and Performance

[Naif_Prof]

Hi , Using PostbackURL property in ASP.NE 2 to pass the values of controls between pages Now if we have different controls in page 1 and we link page1 to page 2 by setting the PostbackURL property of link button in page1 to be linked to page 2 And in page 2 we use Request.form[“Control Name”] to get the values of some controls of page 1 Is this impact the performance of application ( slowness ) if page 1 contain a lot of controls ?

No. If you are using Request.Form, you are reading the values directly from the form data sent from the browser. It doesn't involve the server controls of the first page at all.

--- b { font-weight: normal; }

Ok thanks Im using master pages, when i use PostBackURL with button control to pass the values of controls in page 1 to page 2 its give me the follwing exception Exception Details: System.NullReferenceException: Object reference not set to an instance of an object. But when I use it with normal pages that not use master pages its work with postbackurl in page 1 and request.form in page 2 to get the values of controls in page 1 why its nor working withe pages that use master pages

The id of controls inside containers, like in master pages, gets the id of the container prepended to it. Check the source of the html page to see what the field's names are.

--- b { font-weight: normal; }
