Drag and Drop support required

Hi Xinen,

1) Great idea!  We've done some research and found a way to support both block and full line paste/drop compatibility with Visual Studio.  This will be in the next maintenance release.

2) A TextChanged event will be fired with this change type: TextChangeTypes.DragAndDrop.  You could handle that event and look for that change type and do your caret set there.

1) Thanks! Will you implement the 'MSDEVColumnSelect' clipboard format? Because we need it for dragging block text to/from other applications (other than VS) as well.

2) I did try setting the Caret in the DocumentTextChanged event but the Caret seems to be set again after that.

3) I have one more need: I need to know when there is a Drop on another application. The wpf Drop event only triggers when my application is the target drop app. There's no way to know whether my datasource has been dropped elsewhere. In DragDropManager, a CutCopyDragAction.Drag event is raised before DoDragDrop, but not after. Would it be possible for you to raise another event right after?

Hi Xinen,

1) Yes we support that clipboard format with the change, and also the other one used for the VS line copy.

2) Hmm, it does look like the selection is updated right after that DragAndDrop text change because the replacement is done with a view.ReplaceSelectedText() call.  You might have to do a Dispatcher.BeginInvoke in this scenario so that your caret change happens after all that completes.

3) You could watch TextChanged for this scenario.  If you see a change with TextChangeTypes.DragAndDrop that has no inserted text operation, you'd know it was dropped outside of the editor.
