UpdatePanel Postback causes Popup Window to lose Focus

Sep 18, 2007 02:29 AM|LINK

I have an UpdatePanel that contains a timer and an infragistics webtree and when the timer fire the data is being postback (great). I also have a link that pops up a window using good old javascript window.open(...) (great). Here's the not so great. When the postback occurs and a node in the tree is selected with the javascript window open, it goes to the background. I tried turning off the timer (Timer1.Enabled=false), but that didn't work. Any suggestion is welcome

<script runat="server">

protected stopTimer() {

    timer1.Enabled=false;

}

</script>

<script type="text/javascript">

    function stopTheTimer() {

      stopTimer();

   }

</script>

Hi,

You cann't invoke method at server side directly in javascript.

To stop AJAX Timer contorl,you can do it like this:

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="SetTimerInterval.aspx.cs" Inherits="SetTimerInterval" %>

<!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>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
<asp:scriptmanager runat="server"></asp:scriptmanager>
        <asp:Timer ID="Timer1" runat="server" Interval="3000">
        </asp:Timer>
        <asp:UpdatePanel ID="UpdatePanel1" runat="server">
            <ContentTemplate>
                <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
            </ContentTemplate>
            <Triggers>
                <asp:AsyncPostBackTrigger ControlID="Timer1" EventName="Tick" />
            </Triggers>
        </asp:UpdatePanel>

        <input id="Button1" type="button" value="ChangeInterval" onclick="setTimer();"/>
        <input id="Button2" type="button" value="Start" onclick="startTimer();"/>
        <input id="Button3" type="button" value="Stop" onclick="stopTimer();"/>
        <textarea id="TraceConsole"></textarea>
    <script type="text/javascript">

    function setTimer()
    {
        var timer = $find("Timer1");
        Sys.Debug.trace(timer.get_interval());
        timer.set_interval(100);
        Sys.Debug.trace(timer.get_interval());
    }

    function startTimer()
    {
        var timer = $find("Timer1");
        timer._startTimer();
    }

    function stopTimer()
    {
        var timer = $find("Timer1");
        timer._stopTimer();
    }

    </script>
    </form>
</body>
</html>
