Implementing UpdateProgress


I am using a wizard to enable the user to process credit processing..

at the final step i would like to prevent the user from clicking the finish button more than once..

Further i would like to have a status like "Processing.. please wait" like message displayed..

i have tried this webcontrol in the past./.. but been unsuccessful..

do i need any additional webcontrols to make this work

Well, using the UpdateProgress control is trivial, i.e.:

    <form id="form1" runat="server">
    <asp:ScriptManager ID="sm1" runat="server">
        <asp:UpdateProgress ID="prgUpdate" AssociatedUpdatePanelID="pnlUpdate" DisplayAfter="250" DynamicLayout="true" runat="server">
                <!--Stuff to show during update goes here-->
        <asp:UpdatePanel ID="pnlUpdate" runat="server">
                <!--Stuff inside the updatepanel goes here-->

Disabling the submit button however might require some client side interaction, such as:
    <script language="javascript" type="text/javascript">
        /* function for disabling the submitt button with a delay after click event*/
        function DisableControl(controlId) {
              document.getElementById(controlId).disabled =true;
        function DisableControl_SetTimeout(controlId,interval) {
              setTimeout("DisableControl('" +controlId + "')",interval);
        function btnSubmit_Click(control) {

And to use this, set the OnClientClick property of your submit button to point to the javascript function:

btnSubmit.OnClientClick = "btnSubmit_Click(this);"

or add an attribute in code-behind, page_load event such as:

btnSubmit.Attributes.Add("onclick", "btnSubmit_Click(this);")

Hope this helps you solve your problem.
