No RadProgressArea in IE<=9 when using custom httphandler

[Oproma]

We are using the RadAsyncUpload with the RadProgressManager/RadProgressArea and a custom HttpHandler to handle the uploads. In IE10, Chrome, Firefox and others, everything works as it should. However on IE8, IE9 and probably others (6,7) the progress area is never displayed. Enabling chunk uploads solves the problem however it's not an option as we need to use the HttpHandler.

I included the markup for the RadAsyncUpload.

<telerik:RadAsyncUpload runat="server" MaxFileInputsCount="25" DisableChunkUpload="true" HttpHandlerUrl="~/Common/httpHandlers/UploadHandler.ashx" Skin="Office2010Blue" EnableFileInputSkinning="true" HideFileInput="True" InputSize="75" Width="720px" EnableInlineProgress="False" ID="rfUpload" DropZones="#dz" MultipleFileSelection="Automatic" OnClientFilesUploaded="ocfu" OnClientFileUploadRemoved="OnClientFileUploadRemoved" OnClientFileUploaded="onClientFileUploadedNorm" OnClientAdded="OnClientAdded" ChunkSize="0" />

Hello,

Thank you for contacting Telerik Support.

Please register the progress handler as described here. Keep in mind that for small files the upload is very fast and the progress are does not have time to appear. Please test is with larger files. Keep in mind that when DisableChunkUpload is set to true the request length should be preset.

I will be glad to assist you further.
