Cross page posting with Master page

[Guest]

I am not able to reference values by using cross page postings when using
master page.

Currently I am runing on beta 2 of CLR.

Any ideas...

Thanks

What problem are you having?

 

[Guest]

Many thanks Brock for responding back, I am actually stuck.

K my problem is that I am using cross page posting from one page to another.
It seems to work fine if I do not use Master page but the moment I use master
page the code reference does not work on the second page.

TextBox textbox1;
textbox1= (TextBox)PreviousPage.FindControl("TextBox1");

on the second page textbox1 shows null with master page.

I do have form tag in master page so I am thinking whether that is the
problem or what is the work around.

Thanks in advance.

I'd suggest not using FindControl and use the strongly typed PreviousPage.
I posted about this a while back:

You should be able to get the value with code like this:

MyString = Request.Forms("TextBox1").ToString()

Ah, posts like this always bring a smile to my face.

All I can see is a bright future full of consulting work to clean up
after this new crop of web developers who don't even realize that they
are submitting forms from HTML pages. Yessir, we're set for life,
fellas!

I had to do this to access my hidden field's value:

Request.Form["ctl00$ContentPlaceHolder1$PassedProductCategoryID"]

OR

Page.PreviousPage.Master.Controls[3].Controls[3].FindControl("PassedProductCategoryID")

which is more ".NET" but still not very good as FindControl isn't recursive so I still needed to use Controls[3] for the Form and the second Controls[3] for the content place holder. Check Rick Strahl's post on recursive FindControl http://www.west-wind.com/WebLog/posts/5127.aspx

I've seen other people just do Master.FindControl("controlName") - but for some reason that never works for me?

Brock's method doesn't work in the situation I have either, as I only do a cross page postback the first time to my page, subsequent times need to stay on the same page.

K. Scott Allen has some good stuff on Masterpages at http://www.odetocode.com/Articles/450.aspx including a bit about cross page postbacks and using the @MasterType directive, I'm going to give it a go

Cross Page Posting while using Master Pages

Hi,
For the users still looking for the solution.

Try this :
///Getting ContentPlaceHolder from the Previous Page
ContentPlaceHolder Holder = (ContentPlaceHolder)Page.PreviousPage.Master.FindControl("ContentPlaceHolder1");
/// Getting Textbox from the ContentPlaceHolder
TextBox tbox= (TextBox) Holder.FindControl("TextBox1");

hope this will help
