    [CLOSED] Open window from checkbox

    Hi Guys
    Just learning ext and javascript ... i need to display an ext:window when a checkbox is "checked" (and only when it is checked, not unchecked) ... easy to do on a postback but I'd like to do it on the client.

    Any assistance much appreciated.
    (btw, really appreciating the Coolite tools).

    Hi Adrian,

    You can attach a <Check> Listener to the <ext:Checkbox> to control the show/hide of a <ext:Window>.

    The following code sample demonstrates.


    <ext:Checkbox ID="Checkbox1" runat="server">
            <Check Handler="(this.checked) ? Window1.show() : Window1.hide();" />
    After the v0.6 release, I would suggest changing the <Check> line to the following sample.


    <Check Handler="(this.checked) ? #{Window1}.show() : #{Window1}.hide();" />
    Wrapping the "Window1" ID with a #{} token will instruct the Toolkit to replace the #{} token with the actual .ClientID of the Control. The controls are instantiated client-side with their .ClientID's, which may be different than their server-side .ID.

    Out of interest sake, I also tried the same scenario using the new <AjaxEvents> feature of v0.6. The following sample demonstrates adding a <Check> AjaxEvent to the <ext:Checkbox> which makes an ajax request/response back to the server and fires a custom "Checkbox1_Check" event.


    <script runat="server">
        protected void Checkbox1_Check(object sender, AjaxEventArgs e)
            if (this.Checkbox1.Checked)
    <ext:Checkbox ID="Checkbox1" runat="server">
            <Check OnEvent="Checkbox1_Check" />
    Hope this helps.

    p.s. Thanks for the feedback! much appreciated.

    Thanks Geoffrey ... works like a charm ... the support you're providing through this forum is brilliant.

    Really looking forward to <AjaxEvents> ... its going to make working with Ext for asp.net developers - like myself - so much easier (and more powerful).
