Hi,

I encountered a problem on IE9. I used AsyncFile Upload control. I needed Manual Upload and Multiple File Selection. I could select only one file in the open file dialog on IE9 and the upload module was IFrame. But On Firefox I could select several files at a time. After I had switched off the Manual Upload feature I could select several files at a time on IE9 and the upload module was Silverlight. What should to do in order the Multiple File Selection feature works on IE9?

Environment: Win7 Ultimate x64 SP1, IIS7, VS2010 SP1, Silverlight 5, Telerik Radcontrols for ASP.NET Ajax Q3 2012 SP2 v.12.3.1308.0

There is my project in the attachment.

Thank you in advance.

Hi Denius,

Thank you for contacting Telerik support.

This is a limitation of the manual Upload functionality- it can only be used with multiple files in browsers which support FileApi. When manual upload is used under IE 9/8/7 the upload module is IFrame. Please excuse us for this limitation of our control.

Hope this will explain the issue if you have further question |I will be glad to assist you again.

All the best,
Plamen

MultipleFileSelectionTest.zip

Hello Vel,

We tested your configuration and were not able to reproduce any issue with MultipleFileSelection on IE9. I attached a sample project that you could give a try and check whether this functionality works correctly at your end. Telerik.Web.UI.dll must be added to the bin folder, in order to run the project.

Hello Vel,

The issue you are facing is not related to the AsyncUpload and its manual upload functionality, which is the subject of this thread. Please open a separate thread with product RadWindow and provide as much details as possible on your scenario. This will help us reproduce the issue and suggest a possible solution. It would be helpful if you could isolate the window to a sample runnable page that demonstrates the behavior you have experienced and attach it for further review.
