hi all.. i cannot find any page that solve this things (that should be very easy for sure!)

1. how can i reload a page that has a control inside?? the control validate the user but the page_load fires before the control and that's make me to force a refresh so the page know that the user is validated...
2. how can i hide a collumn in a datagrid that is bounded to a data reader (the grid has some columns that has to be visible some times and sometimes not, depending on the user)
3. how can i know wich pages call me?? (since i have querystrings in the url, how can i know the last one before the one that call me..)
EX: page1 call page2 and i want to know the exact url of page1

thanks in advance...

1. ???
2. DataGrid1.Columns(column index).Visible = False
3. Look into the HTTP_REFERER server variable.

3.
If you are using IIS server then 'Request.ServerVariables("HTTP_REFERER")' should return the url from which your page is called. If the user is coming to the page by typing the url in address bar it will return a string of length 0. I am in hurry, I will answer the rest later, sorry about it.

thanks guys...

the data grid doesn't have columns members... or at least i cannot find it..

thanks for the 3.. i will try to requery the first one..

i have a page, with severals controls inside. One of them validate the user. When the user insert his data on that control, the secuence when he press the submit button is first the load_page from the main page, then the submit button of the control.. that cause a refresh first in the page, then in the control. i want the other way (or at least first the control!). better now???

thanks in advance again jim and Sai Puli...

What version of the framework are you using.. I tested the code I gave yoiu, it worked fine.

As for #1, you can't change the way .NET works, when you click a button, it causes a post back.

thanks for you reply.. framework 1.1 sp1...

and i know about postback.. maybe im querying wrong :(

let's see if i can explain better...

my pages has several user controls.. how can i make that the code for the controls fire before the page_load events?? or at least force a refresh on the page?

HTH

Gonzalo

What do you mean code run.. do you have validators on the controls?

i dont follow you now.. i dont have validators on the control.. it just a login control that put a session variable to true when the user logs, but if the pages show some things only if the user is logged, i have to force refresh the page to see that things.

Why force a refresh.. If the user is authenticated, set the controls visible property to true or false accordinly.. Also, you said "login control" are you using asp.net 2.0?
