    [CLOSED] [1.0] NORESPONSE in Button with IsUpload=true

    Hi,

    I want to offer a PDF Download via an Ext.NET Button but I am always getting a NORESPONSE error.

    Here is my sample (with a gif file download, but should be the same like a PDF url)

    <%@ Page Language="C#" AutoEventWireup="true" %>

<%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %>
<!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></title>
</head>
<body>
    <form id="form1" runat="server">
    <ext:ResourceManager ID="masterScriptManagerCoolite" runat="server" Theme="Gray"
        ScriptMode="Debug" />
    <div>
        <ext:FormPanel ID="formPanel" runat="server" LabelWidth="80" Border="false"
            ColumnWidth="0.65">
            <Items>
                <ext:Button runat="server" ID="buttonManual" Text="" FieldLabel="Test" Icon="PageWhiteAcrobat"
                    Flat="true">
                    <DirectEvents>
                        <Click Url="https://examples2.ext.net/resources/images/ext_net_badge.gif" Timeout="60000"
                            IsUpload="true" FormID="formPanel" Method="POST" Before="Ext.Msg.wait('Downloading...', 'Download');">
                            <EventMask MinDelay="250" />
                        </Click>
                    </DirectEvents>
                </ext:Button>
            </Items>
        </ext:FormPanel>
    </div>
    </form>
</body>
</html>
    Regards,

    Martin

    Hi,

    1. You cannot use external url because XMlHttpRequest (ajax) doesn't work with cross domain urls
    2. IsUpload uses POST request always but web server forbid POST request for many type of files (including images)

    Therefore I recommend to create http handler and pass url to that http handler via DirectEvent, in that handler download the file via WebRequest class and pass it back to the client
    WebRequest request = WebRequest.Create(myurl);
WebResponse response = request.GetResponse(); 
StreamReader sr = new StreamReader(response.GetResponseStream(), System.Text.Encoding.Default);
String file = sr.ReadToEnd();
context.Response.Write(file);
sr.Close();
