Hi Fernando,

How large is this file? Maybe you are exceeding the maximum allowed size. Check if there are any errors while uploading file in Firebug Network Monitoring tool. On the Troubleshooting page you will find codes of all possible errors that you can get. Also check if you give write permissions to the Temporary and Target folders.

I suddenly have the same problem on my workstation and on a server at customer site. It used to work fine on my laptop.
I can't find an explanation on the Yellow blink in any documentation - what is it supposed to mean ?

Thanks.

Hi Jens,

Yellow blinking means that file uploading is in progress. If it freezes or doesn't disappears for a long period of time this indicates that file upload has failed. Try to handle OnClientFileUploadFailed event and paste the error message here:

<telerik:RadAsyncUpload runat="server" ID="RadAsyncUpload1" OnClientFileUploadFailed="OnClientFileUploadFailed">
<script>
function OnClientFileUploadFailed(sender, args) {
    if (args.get_message()=="error") {
        args.set_handled(true);
    }
}
</script>

I'm experiencing the same thing and tried this and the javascript never triggers.

Hi Matt,

Usually the yellow color indicates problems with the upload handler. Try to use Firebug Net Tool (or any other dev toolbar) to determine, why you are getting this error. If the handler is registered correctly you shouldn't get the yellow dot. In case you are using a Custom Handler try to debug your code and make sure that there are no errors in the handler.

If everything is okay you should be able to browse:

http://localhost:62171/Telerik.Web.UI.WebResource.axd?type=rau

{ "message" : "RadAsyncUpload handler is registered successfully, however, it may not be accessed directly." }


If the information above doesn't help please attach a fiddler log, so we can troubleshoot the problem.

Thanks.
