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.

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.

IE9 forces every iframe to use the same DOCTYPE employed by the container document.

Is this issue fixed in later releases?.
I am experiencing the IE9 & ManualUpload = true issue with the 2013.3.1324.45 version of Telerik.Web.UI?.
Thanks
It looks like I could not explain properly- IE9 does not support HTML5 FileAPi upload module and unfortunately ManualUpload is not supported by the other upload modules. This is a limitation of the ManualUpload functionality of the control in this browser and unfortunately the is not workaround of fix for it.
Hope this will explain the issue.

Hello Plamen,
I'm also facing multiple file selection issue in IE9 on windows7 OS. I'm using Telerik.Web.UI.dll Version 2015.1.310.14. Following is the telerik control code. Kindly let me know how to resolve this issue.
<telerik:RadAsyncUpload runat="server" ID="AsyncUpload1" HideFileInput="true" MultipleFileSelection="Automatic"
AllowedFileExtensions=".tif,.tiff,.pdf" OnClientFileSelected="onFileSelected"
OnClientFileUploadRemoved="onFileSelected">
<Localization Select="Select Files" />
</telerik:RadAsyncUpload>
Thanks,
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.

Our application developed with Asp.NET 4.5 and Bootstrap3 Telerik version 2015.1.310.40. When mouse over on radwindow main page UI getting collapsed. This issues happening only on IE9. Kindly help me. Thanks in advance.
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.
