    How can i do Button EventMask Hide

    Hello there

    According to that thread
    i would like to do the same but i would like to hide the mask only when download finished.
    The actual question is if there is any way to do the previous with out use the classic ajax way with IHttpHandler.

    Thx a lot for your time

    Hello @asteriskgr! Welcome to Ext.NET Forums!

    There's no event bound to the end of a download on pages. This is not an Ext.NET nor ExtJS limitation, but browsers'. Unless you can bind the download to some event.

    When sending files to the server (upload) though, that is possible. Cause the server can send an ajax update to the page once the upload completes.

    Here are two examples showing browser interaction with client-bound and server-bound processes (that could be replaced by the upload of a file):
    - Progress Bar - Client Side Update
    - Progress Bar - Server Side Update

    There are some StackOverflow discussions on how to fire events after downloads complete in client-side:
    - Browser event when downloaded file is saved to disk
    - Browser download complete event

    Once you can successfully trigger the event, to remove the mask from a component, for example if it was defined with ID="myComponent", the command would be:

    Server-side (C#):
    // Adding mask:
    myComponent.SetLoading("Element is masked");
    myComponent.Element.Mask("Element is also masked.");
    // Removing it:
    Client-side (javascript):
    I hope this helps!

    .Mask() and .Unmask() methods have been added for a Component.

    It will go to the v3.3 and v4.0 beta releases.

    By the way, there is also a .Call() method on a Component. You can use it to call any client side method from C#.
    myComponent.Call("mask", "mask message");

    Thanks Daniil!..

    In other words, from code behind (server side) now it will be possible to:

    much like its javascript (client side) as shown on my first reply:
    But that code behind approach will only be available once Ext.NET v3.3 (or the upcoming v4) are released. (while the javascript one is actual to the current 3.2.1 release).
