title: EXT.NET 2.0 file upload field browse button not working
body: <p>I'm trying to use file upload field. I used first example of the ext.net demo site. This link: <a href="http://examples.ext.net/#/Form/FileUploadField/Basic/" rel="nofollow">http://examples.ext.net/#/Form/FileUploadField/Basic/</a> </p>
  
  <p>I run my code, but when I click the browse button, the window didn't open. I source about that.I researched this issue. And I found a source. This link: <a href="http://forums.ext.net/showthread.php?15522-CLOSED-Programmatically-click-fileuploadfield-browse" rel="nofollow">http://forums.ext.net/showthread.php?15522-CLOSED-Programmatically-click-fileuploadfield-browse</a> . In the source vladimir says: there is no way to open file dialog programaticaly (as I know, IE (not sure about IE9) allows it but other browsers don't support it)
  The reason: security risk. I use IE9. So I download IETester program. I try my code but browse button did't open again. What should i do</p>
  
  <p>Here is the code:</p>
  
  <pre><code>&lt;%@ Page Language="C#" AutoEventWireup="true" CodeFile="Fileuploadfield.aspx.cs" 
  Inherits="Fileuploadfield" %&gt;
  &lt;%@ Register Assembly="Ext.Net" Namespace="Ext.Net" TagPrefix="ext" %&gt;
  
  &lt;script type="text/javascript"&gt;
  var showFile = function (fb, v) {
      if (v) {
          var el = Ext.get('fi-button-msg');
          el.update('&lt;b&gt;Selected:&lt;/b&gt; ' + v);
  
          if (!el.isVisible()) {
              el.slideIn('t', {
                  duration: .2,
                  easing: 'easeIn',
                  callback: function () {
                      el.highlight();
                  }
              });
          } else {
              el.highlight();
          }
      }
  };
  &lt;/script&gt;

  &lt;/head&gt;
  &lt;body&gt;
  &lt;form id="form1" runat="server"&gt;
      &lt;ext:ResourceManager runat="server" ID="ResourceManager1" /&gt;
      &lt;ext:FileUploadField ID="BasicField" runat="server" Width="400" Icon="Attach" /&gt;
  
          &lt;ext:Button ID="Button1" runat="server" Text="Get File Path"&gt;
              &lt;Listeners&gt;
                  &lt;Click Handler="var v = #{BasicField}.getValue();  
                     Ext.Msg.alert('Selected&amp;nbsp;File', v &amp;&amp; v != '' ? v : 'None');" /&gt;
              &lt;/Listeners&gt;
          &lt;/ext:Button&gt;
  &lt;/form&gt;
  &lt;/body&gt;
  &lt;/html&gt;
