    Hi,

    Unfortunatelly, the back button is browser UI element which is not accessable from javascript. But you can clear history

    Hi,

    Maybe handling the <WindowUnload> event would help.

    Example

    <%@ Page Language="C#" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.NET Example</title>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server" WindowUnloadMsg="Testing...">
            <Listeners>
                <WindowUnload Handler="return true;" />
            </Listeners>
        </ext:ResourceManager>
    </form>
</body>
</html>

    Another option is using the <ext:History> component.

    See https://examples1.ext.net/Examples/M...History/Basic/

    RE: [CLOSED] Back button

    The ext:history option is great! Thank you very much!

    Based on the sample I implemented it this way:

    Add function in the script block :




    function blockBackButton() {


History1.add('empty');


}
    The onready event must call blockBackButton() once..

    In the ASPX block :




    <ext:History ID="History1" runat="server" >


<Listeners>


<Change Fn="blockBackButton" />


</Listeners>


</ext:History>

    I just tested with Google Chrome and my solution does not work. I think that change event is never raised. Do you have any idea why? I work with Internet Explorer, Firefox and Safari and it works well.

    Thanks.

    Hi,

    I just tested the page below. Yes, it works well in IE9 and FireFox. Also it partially works in Chrome. "Partially" means the following. If I open a new tab and load this page, then it seems don't work, i.e. an empty page is opened after clicking the Back button. If I open some other page first, then open my page, then it works well.

    Looking this issue up on the internet might help to find some solution for Chrome.

    Example
    <%@ Page Language="C#" %>
 
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" 
    "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
 
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Ext.NET Example</title>

    <script type="text/javascript">
        var blockBackButton = function () {
            History1.add("empty");
        };
    </script>
</head>
<body>
    <form runat="server">
        <ext:ResourceManager runat="server">
            <Listeners>
                <DocumentReady Handler="blockBackButton();" />
            </Listeners>
        </ext:ResourceManager>

        <ext:History ID="History1" runat="server" >
            <Listeners>
                <Change Fn="blockBackButton" />
            </Listeners>
        </ext:History>

        Try to "Back"
    </form>
</body>
</html>
