Display label after page postback

Question

I have a form with textboxes and 2 buttons ‘Save’ and ‘Cancel’.

Save - stores the data to the database and clears all the fields. Cancel - clears all the fields. (I am clearing all the fields by doing a server.transfer to the same page).

I want the label to display “Course Added” after I click the Save Button and clear the form.

I have looked into View State and Session Variables but havn’t found a concrete solution to my problem as yet. Any help or advice is much appreciated.

Below is the code for my aspx and code behind. Thanks.

Admin_Course_Add.aspx

<asp:Content ID="Content3" ContentPlaceHolderID="rightNavigation" runat="server">

<script type="text/javascript">
`/`/JS for validations
  `enter code here`      $(document).ready(function () {
            $("#form1").validate({

                rules: { '<%=tbCourseName.UniqueID %>': { required: true, maxlength: 25 },
                    '<%=tbShortName.UniqueID %>': { maxlength: 10 },
                    '<%=tbPointScale.UniqueID %>': { required: true, digits: true },
                    '<%=tbDescription.UniqueID %>': { maxlength: 50 }
                },
                messages: {}
            });




            $("#imgBtn_A_add").click(function (evt) {
                // Validate the form and retain the result.
                var isValid = $("#form1").valid();

                // If the form didn't validate, prevent the
                //  form submission.

                // If the form didn't validate, prevent the
                //  form submission.
                if (!isValid)
                    evt.preventDefault();
            });

            $("#imgBtn_A_cancel").click(function () {
                $("#form1").validate().cancelSubmit = true;
                $("#form1").submit();
                return false;

                });

Is this a job for a cookie? Redirecting takes viewstate out of the picture, and I don't care much for session variables. Other than that you've got cookies or querystrings... — Tim
Query Strings does sound like something I need to look into. Thanks! — user1288906

First Why You Clear the Field By ServerTransfer??

Second You can Send Parameter in the QueryString

for example:

 Server.Transfer("Admin_Course_Add.aspx?ClearParams=Yes");

and in the page load you would add

if(Request["ClearParams"].ToString() == "Yes")
{
  Show My Lable
}

Display label after page postback
