Yeah. As I said, non-IE browsers (including Mozilla Firefox) doesn't support "CSS expression". So, I was looking for the solution and I found that it's too wide to cover since the solution for one case are differ from the sol for another case even all are using expresion.
Okay. Here is the solution (98%) for your problem. (I said "98%" solution because this code won't work on IE7.  )
The following code that I'm going to show is based on this great article Pure CSS Scrollable Table with Fixed Header[^] and Microsoft ASP.NET 2.0 CSS Friendly Control Adapters 1.0[^].
Let's start !!
#1. Download the template from http://www.asp.net/cssadapters/
#2. Install it in your machine. ( Check-out this page to know how to install )
#3. Open C# "CSS friendly adapter Template" in Visual Studio 2005
#4. Delete "WalkThru", "CSS" and "Javascript" folder.
#5. Delete all files (except GridViewAdapter and WebControlAdapterExtender ) in App_Code\Adapters.
#6. Put the code (I will post in next thread because the text editor here is really bad in aspx
#7. Pasted the code below in code-behinded file.
<br />
protected void Page_Load(object sender, EventArgs e)<br />
{<br />
GridView1.DataSource = getDataTable();<br />
GridView1.DataBind();<br />
}<br />
private DataTable getDataTable()<br />
{<br />
DataTable dt = new DataTable();<br />
<br />
DataColumn dc1 = new DataColumn("Header1");<br />
dt.Columns.Add(dc1);<br />
DataColumn dc2 = new DataColumn("Header2");<br />
dt.Columns.Add(dc2);<br />
DataColumn dc3 = new DataColumn("Header3");<br />
dt.Columns.Add(dc3);<br />
<br />
for(int i=0;i<50;i++){<br />
DataRow dr = dt.NewRow();<br />
dr[0] = i.ToString();<br />
dr[1] = i.ToString() + " Cell";<br />
dr[2] = i.ToString() + " Text";<br />
dt.Rows.Add(dr);<br />
}<br />
<br />
return dt;<br />
}
#8. Paste (override) the code below in GridViewAdapter.cs under App_Code\Adapters.

#9. Then, run the application..
That's all. But note that it doesn't work on IE7. and you need to modify the code if your gridview has more/less than 3 columns. (Thanks to "Terence Ordona, portal[AT]imaputz[DOT]com" for CSS scrollable table.)
Note:
Browser Support (table is scrollable with fixed headers)
* Opera 7.x + (All Platforms) :: Tested with 7.2x and 7.5x
* Mozilla 1.x + (All Platforms) :: Tested with 1.0x and 1.6x
* IE 6.x + (Windows) :: Tested with 6.0x
* Safari 1.x + (MacOS) :: Tested with 1.2x
* Konqueror 3.x + (Linux / BSD) :: Tested with 3.2x
Almost works (table is scrollable)
* IE 5.x + (Windows) :: Tested with 5.0x and 5.5x
Doesn't work (table is not viewable)
* Opera 5.x and 6.x :: Tested with 5.1x and 6.x
* IE 5.x + (MacOS) :: Tested with 5.2x

Hello ALL,
I am creating a webpage, which has two pages.
First i login and set the sessionvariable to some value,
it will redirect me to page two.
I will logout and set the session value to null,
my problem here is when i click back in browser after logging out it is going to page two this should not happen.

Wrong. You should call Session.Abandon()

You are seeing cached version of your page by browser. In each page_load event you need to check session existence. If it's not exist, navigate user to login page. Your session check would be like this
if(Session["UserId"]==null)
{
Response.Redirect("Login.aspx");
}

When i click the browser back button the page load event is not triggered ,the page will be directly loaded over the browser.

Yes it won't be fired. But since you are checking Session on page load, he/she can't continue with any other operation. If they click on any button's or refresh the page, it will redirect to login page.
You can try disabling the caching too. But I doesn't looks like a good solution to me.

You have to check in each page load whether the session is null or not null.
If the session value is null means redirect to login page else to the required page.

Hi,
The real problem here is that the When he logout then the page is redirects to the Login page but,If he clicks the browser's back buttion then He can view the content of the page.
Your Idea --putting some code to page load event will not work here because it comes form the Browser's Cache memory. So it will display. Ok

You can disable caching on the client:
Response.CacheControl = "no-cache";
Response.AddHeader("pragma", "no-cache");
Response.Expires = -1;
Then the click on Back will cause a request to the server.

Please refer to the MSDN for information about this methods.
The effect is that the Browser does not hold a copy of the page in its cache and therefore requests the page from the server when the user clicks on the back button. And you can react as you wish on the server side - show login screen or whatever you like.

Yes you are right, But this method will fail with firefox browser. Any other alternative do you know for firefox ?
|
|

It's new to me that this approach fails with Firefox 
I'll have to check this because this is no good news for my applications!
Thanks for the hint.

I want the date format to be in this way like 15-jun-2005 using c# dot net

DateformatFrom = datevalue.ToString("dd-MMM-yy hh:mm:ss");
you can convert the date into the format which ever you want.
I have shown you the one of the way to do that

Yes you can. When you fill dataset, it will contain two datatables. But instead of separating multiple queries with ; symbol, it's better to go for store procedure's.

The Error is : Characters found after end of SQL statement.
I want to the two tables separately in my dataset.
How to do so?

What is it that you are after?
If you want more than two select statements in the table use a join.
If you want different select statements for different tables or adapters,
use different querystrings...
I think for ur case u need :
DataTable dt1=new DataTable();
DataTable dt2=new DataTable();
dt1="first sql select query result";
dt2="second sql select query result";
dataset ds=new dataset();
ds.Tables.Add(dt1);
ds.Tables.Add(dt2);
Hope that helps!!!
I was born dumb!!

Insetd of trying this:
DataAdapter=new OleDbDataAdapter("select * from Table1;select * from Table2",connection);
Try this:
SqlDataAdapter adpt1 = new SqlDataAdapter("Select * From Table1", con);
DataSet ds = new DataSet();
adpt1.Fill(ds);
SqlDataAdapter adpt2 = new SqlDataAdapter("Select * From Table2", con);
adpt2.Fill(ds);
return ds;

As I told before, stored procedure's would be better approach for your problem. Write a stored procedure like
CREATE PROCEDURE [dbo].[MultipleSelect]
AS
SELECT * FROM FisrtTable
SELECT * FROM SecondTable
GO
Now Set command type to stored procedures for your OleDbCommand. Pass this stored procedures and fill dataset. This will give you two tables in dataset. Returning multiple recordset is a recommended practice by MSDN, which boosts performance.
