Plupload Filebrowser does not open - silverlight

Question

I'm trying to use plupload with mvc2 but the filebrowser-window does not open.
my code:
<script type="text/javascript">
// Convert divs to queue widgets when the DOM is ready
$(function () {
$("#uploader").pluploadQueue({
// General settings
runtimes: 'gears,flash,silverlight,browserplus,html5',
url: '<%: Url.Content( "~//Uploades/Horses/" ) %>',
max_file_size: '10mb',
chunk_size: '1mb',
unique_names: true,
// Resize images on clientside if we can
resize: { width: 320, height: 240, quality: 90 },
// Specify what files to browse for
filters: [
{ title: "Image files", extensions: "jpg,gif,png" },
{ title: "Zip files", extensions: "zip" }
],
// Flash settings
flash_swf_url: '../../../../Scripts/plupload/plupload.flash.swf',
// Silverlight settings
silverlight_xap_url: '../../../../Scripts/plupload/plupload.silverlight.xap'
});
// Client side form validation
$('form').submit(function (e) {
var uploader = $('#uploader').pluploadQueue();
uploader.refresh();
// Validate number of uploaded files
if (uploader.total.uploaded == 0) {
// Files in queue upload them first
if (uploader.files.length > 0) {
// When all files are uploaded submit form
uploader.bind('UploadProgress', function () {
if (uploader.total.uploaded == uploader.files.length)
$('form').submit();
});
uploader.start();
} else
alert('You must at least upload one file.');
e.preventDefault();
}
});
});
<div id="uploader" style="height:300px">
<p>You browser doesn't have Flash, Silverlight, Gears, BrowserPlus or HTML5 support.</p>
</div>
If I try to debug the uploadingelemt is showen with out any problems. But If I click add files the window just jumps to the top of my page and nothin else happens.
Firebug does not show any problems.
I've tried in FF4 & IE 8 using flash and silverlight
Any one an idea?
Thank you very much and wish you a nice weekend!

Answer 1

Your browser will use Flash runtime as it is listed before the 'html5'. Flash runtime requires setting of 'container: "my_uploader_container_id"'
And your 'pickfiles' button need to be placed into the DIV with ID 'my_uploader_container_id'.
Another solution is using html5 engine - list it before flash in 'runtimes' parameter. But html5 runtime does not work in IE.
