    [CLOSED] DirectEvent File Download plus MaskEdit issue

    Hi folks,

    Based with example http://forums.ext.net/showthread.php...ll=6#post49277 I'm into an issue.

    My code is

                        <ext:MenuItem ID="menuPDF" runat="server" IconCls="MyIcon_PDF" Text="Exportar a PDF">
                        <DirectEvents>
                            <Click OnEvent="menuPDF_Click" AutoDataBind="true" FormID="form1" Buffer="300" IsUpload="true" Method="GET">
                                <EventMask ShowMask="true" />
                            </Click>
                        </DirectEvents>
                    </ext:MenuItem>
    The issue is just before IE dialog's Open / Save as appears I should hide the EventMask. How can I hidde/stop EventMask message?

    Cheers

    Hi,

    Yes, you have found the post which, generally, answers your question.

    But I will tell about an approach which my colleague has used.

    He also needs a mask for AJAX downloading a report which takes a lot of server time to be built.

    So, he fires a DirectEvent/DirectMethod with a mask to make a report. Not actual downloading, just building the report and saving on server. Then in a Success handler of that DirectEvent/DirectMethod he makes another request to download, certainly, without a mask. But it doesn't take too much time to just download.

    Maybe, this approach will suite your needs as well.

    Daniil,

    thanks a lot for your answer. After apply your [DirectMethod] I'm getting a 200 Bad Request Syntax error. This is the code.

    Please may you help me?

    Cheers

    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="extnet_proves.Default" %>

<%@ Import Namespace="System.Collections.Generic" %>
<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<script runat="server">

    protected void Button1_Click(object sender, DirectEventArgs e)
    {
        //sleep for testing
        System.Threading.Thread.Sleep(2000);
    }

    [DirectMethod]
    public void Download()
    {
        System.IO.StringWriter oStringWriter = new System.IO.StringWriter();
        oStringWriter.WriteLine("Hello world");

        Response.Clear();
        Response.ClearContent();
        Response.ClearHeaders();
        Response.AddHeader("Content-Disposition", "attachment; filename=TEST.TXT");
        Response.ContentType = "text/plain";
        Response.Write(oStringWriter);
        Response.End();
    }

    I think you should pass 
    isUpload : true
    to a DirectMethod.

    Example
    Ext.net.DirectMethods.Download({
    isUpload : true
});
    Also there is no need to set up
    IsUpload="true"
    and, probably,
    FormID="Form1"
    for the Click DirectEvent since there is no actual download during that DirectEvent.

    P.S. By the way, you could replace
    <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="extnet_proves.Default" %>
    with just
    <%@ Page Language="C#" %>
    when posting an example on the forums.

    It will allow us to just copy, paste and run your examples. Now we have to remove it manually each time.

    Not a big deal, but it would make our lives a bit easier:)

    Daniil,

    thanks a lot for your help. Now it works fine.

    My apologies about 
    <%@ Page Language="C#"
    directive.

    Cheers!

    No problem at all! Just a minor note.

    You post good examples, thanks for that.
