This code will help you add a MsgBox in your asp.net file. You can change the function definition to your requirements. Hope this helps!

protected void Addstaff_Click(object sender, EventArgs e)    
    {   
 if (intClassCapcity < intCurrentstaffNumber)     
                {                  
            MsgBox("Record cannot be added because max seats available for the " + (string)Session["course_name"] + " training has been reached");    
        }    
else    
    {   
            sqlClassList.Insert();    
    }    
}

private void MsgBox(string sMessage)    
    {    
        string msg = "";    
        Response.Write(msg);    
    }
