Are you using PostBack. This would usually result in the Page Load code running again.

yes because i am also using a list control every time when i refresh the page the data should be in it without repeating....

So you are selecting an item from the datalist and then it is posting back?
Well what do you want to do with that item from the datalist? Why are you posting back?

Hello. May be you can help me. I've an aspx page PageA and inside of it an iFrame to a page PageB. The PageB has a login. I want from PageA complete the input for login and click on Login Button. How can I do that from PageA usig ASP.Net??
Thanks a lot.

You can't. The frames only exist at the client side, so you can't do anything with them on the server side. You have to use client side script to access the iframe, i.e. Javascript.
Also, to access the PageB from PageA they have to be in the same domain. If you are loading a page from a different domain, you can't do anything at all to it.
Despite everything, the person most likely to be fooling you next is yourself.

One idea is to set an iframe on that area and call required aspx page.

Hello to all
I'm using VS 2008.
I have a masterPage with a variable int PageCodec
on the page son doing the following code
master page = (this.Master as master);
page.PageCodec = 1
The system execute without probleman but when I go to so object page is null and an error of not referenced object, if the code in place come watch
The type 'master' exists in both
There is a folder named App_Code and inside it there's a class that manages session (When a user is logged in and someone tries to log using the same user class that is currently been used, this class doesn't allow it.)
So I clicked on the project with the right mouse button on the option Convert to Web Application, and the folder App_Code was renamed to Old_App_Code.
Now the error that happened in the previous post does not happen anymore, it works perfectly, but I could not understand what happened. Is it a new standard for VS 2008? What I have to do with the Old_App_Code? and Where should I put my class Session?
can someone help me?
thanks.

Hi all,
I'm using Response.Writefile to transmit a file to the client; the method works on one server, but on another with seemingly identical configuration, it sends an empty file - correct name, etc, but no content. No error message. I've tried setting content-length to no avail, and I'm using pretty standard code - and before you ask, yes, the file has something in it. Anyone have any prior experience with this?
Thanks,
Steve

Deleting Response.Close() in my code and moving the code to override the page render command fixed the issue. Why this would only show up on some servers I can't say.

Hi,
I have created a web part which contains a Tree control. This control shows some items under a product. I have created a custom property says "Product Name". User can set this property for web part. Then items under this product will get display as tree nodes.
The problem is if I change Product Name and click on some other link in Sharepoint site and come back to this page, tree will show items under specified product but if I change product name and click on OK on the property section, page is getting refreshed but it still shows previous tree. Mean to say web part is not getting refreshed.
I checked few blogs which have mentioned about this problem but didn't give any solution.
Please help me by posting the solution.
Thanks And Regards.

It depends on what you mean by dynamic. If you want to dynamically add rows on the server side and you are binding to a DataTable/Collection you can add rows to the DataTable/Collection and then re bind the GridView.

what i want is that
there is a button
when i click on this button a new row should be added

in all page except master page i wrote:
protected override void InitializeCulture()
{
if (Session["lang"] != null)
{
string selectedlang = Session["lang"].ToString();
UICulture = selectedlang;
Culture = selectedlang;
Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(selectedlang);
Thread.CurrentThread.CurrentUICulture = new CultureInfo(selectedlang);
}
base.InitializeCulture();
}
in masterpage in click event of link buttons
protected void LinkButton1_Click(object sender, EventArgs e)
