i can create session objects that will end when the user logs out. those pages will not be accessible anymore unless the user logs back in. but if the user clicks the 'Back' button at the toolbar, the last page will display even though the user has logged out. how i can prevvent the user from accessing the pages by clicking the 'Back' button after he has logged out.

You have to set the cache to no-cache and expire the page, e.g. use the following code for every page:
Response.ExpiresAbsolute = DateTime.Now.AddDays(-1)
Response.Expires = -500
Response.CacheControl = "no-cache"
-----

MSDN Library:
"The Expires, ExpiresAbsolute and CacheControl properties have been deprecated in favor of the methods of the HttpCachePolicy class available through the Cache intrinsic object to control the IIS output cache and client caches."
Use this instead:
Response.Cache.SetExpires(DateTime.Now.AddDays(-1))<br />
Response.Cache.SetCacheability(HttpCacheability.NoCache)

You can specify css has to be used for print in the link tag. Also, css can specify units maybe that can help.

Well, datasource property take only 1 table. It seems that you have some kind of parent child grid. In that case you have to add a relation between two tables. And on rowdatabound you will have to get the child control from the grid and bind the child control by getting the child records by createchildview command. If you don't have parent child grid then you need to have all data in one table. You can merge tables before biding the grid or you can get one table from the stored procedure using the union command.

Hello Mr. SABhatti,
Thank u very much for reply.
well as i write in my previous post that i write one stored procedure which returns two tables. First table binds to gridview and second table's fields values assign to different different labels in my page. There is no relation between this two table.

if you just want to access the second table in dataset you can do that like dataset.Tables[1].Rows...

You can't change the default behavior of a link. When a link is clicked, browser will move to the specified location.

Set AutoPostBack=false for the control

You can use a span in the place of a link with a style of underline and use the javascript onclick even to handle the click.

In the site I have a file to store an integer.In a asp.net page I have I read this file and let the user create a record in the database table and after addition the integer in the file is increased by one. I need the integer stored in table to be unique. What I worry about is if multiple users open the same page and both will have the same integer(read from file). Should I use lock for the file ? What is your recommendations ??

If you only want the id in the database table to be unique, that's best handled in the database.
Set the field in the database to be identity, counter or auto_increment, depending on the database you are using.
After you have create the record in the database, you can get the identity that was created, for example using "select scope_identity()" if you are using MS SQL Server.

My table already has an identity column. is it possible to create two identity columns for a table ?
|

No.
Create a new table with just an identity field, and use that to create unique values, instead of trying to use a text file.

It depends on browser. I think IE7 onwards displaying this. IE6 won't display this

Minor correction: IE6 will show it if you bookmark it and then revisit the page. Which is a bit rubbish.

Hi,
I am trying to repeat image in word (containing HTML) for some table cells. But the image is not displayed in MS Word. It displays in IE / other browsers. I am using background-image and repeat x for this.
I searched for the same and found that background images are not supported in MS Word. Is there any workaround for this.
Thanks !

Hi Guys and Gals,
I am using a javascript function to update a label in a template column of a gridview. This all works fine, but the problem we are having is that when we want to update the database with the changes, the labels returns the old values instead of the updated values in the labels.
Here is our JavaScript. If anyone can tell us what we are doing wrong or how to correct this problem, it will be greatly appreciated.
string script = @"
function calcQty(QtyPerCarton,Cartons, num)
{
if(num < 10)
num = '0' + num;
var i = document.getElementById('dg3_ctl'+num+'_txtCartonsPicked');
var carPicked = i.value;
var out;
if(carPicked <= Cartons)
{
out = parseInt(carPicked * QtyPerCarton)
}
else
{
alert('Cartons Picked cant be greater than Cartons');
return;
}
var lbl = document.getElementById('dg3_ctl'+num+'_lblQtyPicked');
lbl.innerHTML = out;
}
";
this.RegisterStartupScript("Calc", script);
Kind Regards,
Elizma
