Clicking on custom button with RadWindow maximizes the window

[Duy]

I am having an issue with a custom "help" button that I added to the Radwindow.  When I click on my custom button, the window maximizes. And when I click on the custom button again, nothing happens. I am NOT expecting the window size to change. Does anyone know what is going on?

Is there some embedded event that I need to cancel?

function showRadWindow() {
    window.radopen("SamplePage.aspx", "sampleWindow");
    return false;
}

function AddHelpIcon(radWindow) {

    var radWindowDom = document.getElementById(radWindow.get_id());
    var TitleBar = radWindow.GetTitlebar();
    var parent = TitleBar.parentNode;
    var oUL = parent.getElementsByTagName('UL');
    var oLI = oUL[0].getElementsByTagName('LI'); //Get the unordered list html element

    if (oLI[0].id != "HelpListItem") { //If first (list item) does not have the id of "HelpListItem"
        var newLI = oLI[0].cloneNode(true);
        var newA = newLI.getElementsByTagName('a'); //html anchor
        oUL[0].style.width = "93px"; //width of titlebar
        newA[0].className = "helpbutton"; //class inside .css file
        newA[0].title = "Help Button";
        newA[0].lastChild.innerHTML = "Help Button";
        newA[0].onmousedown = callHelpFunction;

        if (radWindowDom.attributes["HelpId"] != null) {
            newA[0].setAttribute("helpId", radWindowDom.attributes["HelpId"].value);
        }

        oUL[0].insertBefore(newLI, oLI[0]);
        oLI[0].id = "HelpListItem"; //Name the first (list item) ID to "HelpListItem"
    }
}

function callHelpFunction(e) {

    //Do something

    //Cancel event!
    if (!e) e = window.event;
    return $telerik.cancelRawEvent(e);
}

<asp:Button Id="button1" runat="server" Text="Open Rad Window2" OnClientClick="showRadWindow(); return false;" />

I noticed if I set an JS alert in my callHelpFunction function, and close the window after the alert pops up, it DOES NOT maximize the window. Strange huh?

Anyone?

[Duy]

I am still having trouble with this if anyone can PLEASE help.

Hello Duy,

 I prepared a sample demo based on your code but unfortunately to no avail. Would you please examine my page and let me know what I am doing wrong? Once I am able to observer the issue locally I will do my best to help.

Can you try removing the alert so that when you click on the help button, nothing happens? I used your code and I was able to recreate the issue when I removed the JS alert in the callHelpFunction function.

Also are you using the following?

Thanks for your assistance!

Hello Duy,

 Thank you for the provided additional details, the issue comes from the fact that you have cloned the maximize button. If you want to use the clone, you should take care of clearing the attached handlers, etc, and to make sure that the button is not inside the buttons array in the window.

However, since this is more complex solution and also might need custom code I recommend to simply create new elements as explained in the article below instead of cloning:
