Drag/Drop functionality for Upload Control

[Carolyn]

Is it currently possible to drag/drop files from a surface outside of the Silverlight control (i.e. Desktop) onto the Upload Control?  If not, are there any future plans to implement this feature?

Hi Joe Dattilo,

Thank you for your interest in the RadUpload for Silverlight.

Till now the RadUpload does not support drag & drop (inside Silverlight plugin). Please note the drag & drop from out-side the plug-in (i.e. the desktop) is not possible due to the Silverlight's security restriction.

We hope this information will help you.

Sincerely yours,

Ivan,

Now that Silverlight 4 is almost RTM and does support drag and drop, I am really looking forward to your adding drag and drop functionality as I had read in another post.  Please keep us updated. Thanks!

Hello John,

Thank you for contacting us.

Yes our SL4 release already include the Drag & Drop functionality. Even more you can try it - just download our latest internal build (RadControls_for_Silverlight4_RC_2010_1_0402) and play with AllowDrop, IsDropFilterEnabled and FilterIndex properties. Other interesting thing is the RadUploadDropPanel class - you can place an instance of it as a drop target.

If you need more information on this topic please drop us a line.

Is there still the same security restriction with Silverlight 4 that prevents drag and drop from the desktop when using a Silverlight user control in an ASP.NET website?

[Tina Stancheva]

Hi Mike Dennis,

No there are no such restrictions currently. You can test the DragDrop functionality in this demo of the RadUpload by simply dragging an image to the Drag Items Here to Upload section.

Still, if you encounter any specific issue, please let us know and we will do our best to help you implement your scenarios.

Kind regards,

Tina,

Is there a setting in IIS 7.5 that would cause this functionality to not work correctly?  When I tried the code from that sample, the test html page worked correctly with the drag drop with opening from the filesystem, but it didn't work when I ran it with the path in IIS.  It also isn't working from IIS when it is part of a user control.  The upload functionality works correctly otherwise in IIS, but the drag and drop functionality isn't.  There aren't any visible errors, it just doesn't let me drop an image in the control when I run it through IIS.  The site is set up for ASP.NET 4.0.

Edit: It looks like my issue was because the site was still adding Silverlight controls like it was with v2.  When I removed the System.Web.Silverlight.dll out of my bin folder, the generated html file now works.

Hi,
Iam using telerik silverlight radupload with drag and drop.It is working fine in Vs.net.
 But when iam trying to integrate it in sharepoint,RadUploadDrop Panel is not working.

I used .xap from Dotnet developed project.And i think it is due to 'radupload handler'..
If it is can u tel me how to configure Radupload handler,or is there any issues with sharepoint..

Thanks
Srikanth

Hello Srikanth,

The RadUploadDropPanel is just a ContentControl that processes its DropEvent and passes this to the instance of the RadUpload. It could be that the RadUploadDropPanel cannot find the RadUpload or it could be that it does not process the drop event. I am not sure that this issue is related to the RadUploadHandler.

All the best,

Hi guys,

I wasn't sure where to post this, but I was wonder if the Telerik team is working on a File Explorer control for SL.  With the drag and drop upload and just a richer interface, this would be huge for me for some use cases.

Thanks!
