I added basic file drag drop to a Silverlight 4 OOB app and found it always gave the no-drop cursor.

If I turn off OOB mode on the same app and found drag drop of files works fine in the browser.

Does anyone know why the requirements for file drag-drop may be different in OOB?

Followup:

I have now also tried the simple drag drop app from here: http://www.wintellect.com/CS/blogs/jprosise/archive/2009/11/26/silverlight-4-s-new-drag-and-drop-support.aspx and when I switch it to OOB mode it also fails to drag drop.

*Note: Am am use the current RC of Silverlight 5, so it is probably a compatibility bug. I notice that half the new features on the Telerik Silverlight Demo site do not loaded under SL5 eother.

  • I've had a quick play with Jeff Prosise's drag-and-drop application and I couldn't reproduce your problem. – Luke Woodward Oct 22 '11 at 20:38
  • @Luke Woodward: There is a chance it is specific to the version of Silverlight I have installed (I currently have 5.0.60818.0 installed). Maybe it is not quite backward compatible? – iCollect.it Ltd Oct 22 '11 at 21:26
  • Perhaps it's because Silverlight 5 is still an RC. I'm using Silverlight 4. – Luke Woodward Oct 22 '11 at 21:41
  • Luke Woodward: I think it *will* be SL5... difficult to keep switching as I am doing SL5 development as well. I will change the tags to match. – iCollect.it Ltd Oct 23 '11 at 07:22

Check that the WindowLess parameter is set to false.

<param name="windowless" value="false" />
