I ran in an interesting issue today. I deployed a web application that uses FileExplorer.... some browsers can't press the "Select" button in the Upload window. The cursor changes to a "hand" like you can click on it... but no amount of clicking around will execute it.
It's strange... I've seen it happen in both IE and Firefox.
I know there is a control buried underneath it.... I've search the forums but didn't see anything.
Telerik.web.ui.dll: 2011.1.322.40
Firefox: 3.6.16
Flash: 10,1,102,64
Any clue on what's going ok ?

We are aware of a such behavior only in scenarios where the left-mouse button is clicked and then the mouse is dragged over the "Select" button (without releasing the mouse button). However, this issue was resolved in previous versions of RadControls for ASP.NET AJAX.
I tried to reproduce it using the provided information but to no avail. Could you please provide more detailed information on the specific scenario? A sample project and / or a live URL reproducing the problem along with the exact steps that need to be executed will be of great help solving this case.
Looking forward to hearing from you,

The "select" button does not work for me when I have EnableAsyncUpload="true"
I have a site with the most basic setup:
<
telerik:RadFileExplorer
runat
=
"server"
ID
=
"RadFileExplorer1"
Width
=
"100%"
Height
=
"600"
EnableAsyncUpload
=
"true"
>
<
Configuration
SearchPatterns
=
"*.*"
MaxUploadFileSize
=
"1073741824"
ViewPaths
=
"~/media/CMS/"
UploadPaths
=
"~/media/CMS/"
/>
</
telerik:RadFileExplorer
>
I can see the files, but when I get to the Async Upload window I cannot click on "select".
NOTE: When I disable flash, I CAN click on "select". This leads me to believe it's a problem with the latest version of flash.
I want to test on your website.... I see that you have a new AsyncUpload demo... but it seems to be broken at the moment.

Can someone else create a super-basic file explorer, and see if the select button works? (have the latest flash player installed).

Here are my observations about pressing the "select" button.
- It works for silverlight.
- it works for pure javascript
- it does not work for flash (I'm using version 10,2,159,1 )

Thank you for the provided additional information. I was able to reproduce this issue using the flash module. I have logged this into our database for further investigation.
For the time being I would suggest you to disable the flash for the RadAsyncUpload. You can do this using the following JavaScript code:
<script type=
"text/javascript"
>
Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable =
function
() {
return
false
; }
</script>
In this help article you can find more information regarding RadAsyncUpload modules.

Thanks for the reply. I'm glad I could bring it to your attention.
Any idea how soon you can fix this? I can't force my users to disable their flash (or install silverlight).
They need multiple file select capabilities. Please let me know,

Currently we are working on this issue, unfortunately I am unable to provide firm estimate on when it will be available. We will do our best to have it fixed for the next service pack.

If so, will the code supplied disable the Flash option (since that seems to be the one causing the issues)? If the Javascript option is used, can they still select multiple files to upload at one time?
Thanks,

Yes, your assumptions is correct. RadAsyncUpload is using the first available module in that order (Silverlight, Flash, JavaScript), and yes, the problematic module is the Flash one.
Unfortunately, multiple file selection is available only for the Silverlight and Flash modules.

Will this code disable the Flash module?
<
script
type
=
"text/javascript"
>
Telerik.Web.UI.RadAsyncUpload.Modules.Flash.isAvailable = function () { return false; }
</
script
>
Yes Adam, this prevent the usage of the Flash module regardless if Flash is installed on the client's machine.

An additional complication on my page is that the RadAsyncUpload is inside a RadAjaxPanel.

This JavaScript is used to override an existing method of the RadAsyncUpload to disables the Flash module of the control not the Flash for entire page, and for this JavaScript to have effect it must be registered on the page after the RadAsyncUpload scripts, thus you need to place it after the ScriptManager declaration.
