Where do I clear the session value?

Question

0.00/5 (No votes)

See more:

I store the EmployeeIds in the session variable and click the button which generate the report of the particular Employees depending on the EmployeeIds stored in session variable. But when I go back where I clicked the button and second time click the button without any selecting EmployeeIds report show me all the report previously selected EmployeeIds records. Now where I have to clear the session? Or any other idea to pass the EmployeeIds to another page and clear it's value when go back to previous page or redirect to other page? Please don't suggest me to use QueryString I don't have to use it.

Try this:

C#

protected void btnLogout_Click(object sender, EventArgs e)
    {
        //clear session variables
        Session["Name"] = "";
        Session["Address"] = "";
        Session["Phone"] = "";
        //redirect to index page
        Response.Redirect("index.aspx");
    }

In page load of first page. if its not postback check whether that session variable exists and delete it.

C#

Session.Remove("varName");

so whenever its going back to previous page, this session variable will be removed.

you can't Set Session Variables to Null.
Session["Employee"]=null will return you a "Null constants is no longer supported.

you can try Like this
Place a back Button on the Page Where you Showing the Report based on selection.
On the Click of that button redirect this to a blank page
there you clear your session and redirect back to page
where you selecting the employee ID.

Let If pageSelect is page Containing your Button
on click you going to pageReport
There you Place a back Button,
on click of Back Button Click
Redirect to pageSwitch
here you clear your session
and also Redirect to pageSelect.

May this helps you.
