WPF Drag & Drop in RightToLeft Direction

Question

Is there a bug in WPF Drag and Drop when it runs in RTL mode? It seems it does not update the drop object area which it's FlowDirection set to RTL. I currently using WPF 3.5 + SP1 and facing this problem, Additionally, it seems this is inherited in WPF 4.0 and also does not work properly in VS2010. Who can providing a solution or workaroubnd ?

Any help would be greatly appreciated.

Answer 1

I have exactly the same behavior. This is a major problem.

Answer 2

The issue has been reported to Microsoft Connect and it should have been fixed in .NET 4.0. Notice, by the way, that the problem does occur if you set FlowDirection = "RightToLeft" on the Window itself, but not if you set it on its controls (i.e. the inner Grid, or main Panel).
