Can anyone plz help me.

               sYear = (string)Request.QueryString["Year"].Trim();
                Session["Year"] = " ";
                Session["no"] = " ";
}

Why do you bother creating variables named "sYear" and "sNo" and then not use them? Session["Year"] contains the string "sYear" does it not? What do you mean you are not getting values in your session? What values are you getting? What values do you want to get?

Yes sorry ! I was not clear actaully..

I have one master page from where we will get these query string values and then I have to store these values into session so that these can be accessed in another pages.... thanks

Okay so go ahead and do that. That does not make anything any clearer.

The only thing you are doing is storing a hard coded string value in your session variables.

Solution 1

Try this:

C#

protected void Page_Load(object sender, EventArgs e)
    {
    sNo = (string)Request.QueryString["no"].Trim();
    sYear = (string)Request.QueryString["Year"].Trim();
    Session["Year"] = sYear;
    Session["no"] = sNo;
    }

Hi

I want these query string values to be used in my another page....Thanks

And that is what it will do - it reads the query strings, and saves them to the session - your version saved the names of the variables into the session instead of the actual values from the query string.
The code you have for reading the session values in page two will work.
The only change I would make is to check IsPostback in the page load and only set the Session values if it is not a postback.

The problem is because you are storing the string name instead of the actual value!

C#

protected void Page_Load(object sender, EventArgs e)
        {
sNo = (string)Request.QueryString["no"].Trim();
               sYear = (string)Request.QueryString["Year"].Trim();
                Session["Year"] = "sYear";//This is wrong!
                Session["no"] = "sNo";//This is wrong!
}

Use the following instead:

C#

protected void Page_Load(object sender, EventArgs e)
        {
sNo = (string)Request.QueryString["no"].Trim();
               sYear = (string)Request.QueryString["Year"].Trim();
                Session["Year"] = sYear; //Assign the actual value!
                Session["no"] = sNo;//Assign the actual value!
}
