            MessageBox.Show("Enter correct username&password")

推荐答案

hi, u can do this way dynamically. Ex:frist Add session 
Session.Add("EmployeeId", txtuname.text);
 retrieve username from the session and store it in a session variable Session("username") = txtusername.Text // Use this wherever u need Response.Write(Session("username").ToString()); 

尝试一下:

Try this:

Session.Add("EmployeeId", txtuname.text);

让我知道你这次能得到什么..

and let me know what you get this time..
