divide your task in to smaller ones and start coding.
than if u find any difficulty ask it.
anyhow... first write code to connect to your db.
then write query to get the desired results
get the data in datareader or in dataset
if the datareader or dataset (whichever u take is empty) then enter fresh data.
else
populate your controls with the data

Hi
i have written this code to populate gridview in asp.net ajax but it doesn't give me any error or populate my gridview so i can figure out what is a problem.my database does't have password it have only user id which i provided.
here is my code
string conString = @"Data Source=DAKESERVER;Initial Catalog=Customer;User ID=sa";
SqlConnection conCustomer = new SqlConnection(conString);
SqlCommand cmdCustomer = new SqlCommand();
SqlDataAdapter daCustomer = new SqlDataAdapter();
DataSet dsCustomer = new DataSet();
cmdCustomer.Connection = conCustomer;
daCustomer.SelectCommand = cmdCustomer;
cmdCustomer.CommandText = "SELECT * FROM CustomerDetails";
daCustomer.Fill(dsCustomer);
GridView1.DataSource = dsCustomer;
GridView1.DataBind();
conCustomer.Close();

If does not have any password then leave the password field blank.
Like:
string conString = @"Data Source=DAKESERVER;Initial Catalog=Customer;User ID=sa; Password=";

Have you initialized the triggers properly???

go to the properties int the update panel and create trigger for loading the grid.
for example if your loading the grid on click of the button then create trgger for that button click even .
it will populate the grid

I have tested with Firefox, Safari, Opera and IE7. I didn't see any problem with "overflow: auto; " CSS property.
I know you still have problem in using expression . I'm still looking for the solution.
For the time being, lets discuss about overflow only. I think that the code above works fine.
is it what you want or still having the problem in using that???
Thanks and Regards,

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.
please give me some idea to avoid this.
Thanks in advance

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.
