I used the example gave by microsoft to drag and drop an object from a ScatteredView to a Surface List Box but it is not working

I developped the example given by Microsoft to drag and drop and object from a scatterview to a surface list box.

The scatterview is workin开发者_如何学Gog, I can move the objects on it. But when I try to drag and drop them on the Surface ListBox nothing happen.

I posed a breakpoint on the method OnDragSourcePreviewContactDown but it doesn't enter in.

Anyone have an idea what could be the reason ?

Thanks for your answers

You should post some code - I don't know MS example. Is it WPF you are using?

Then you may want to look at:
