Hi Jigar -

The XamDataGrid does not contain any special support for drag and drop - as a general WPF topic you might find this article helpful for implementing drag and and drop in WPF controls. http://pavanpodila.spaces.live.com/blog/cns!9C9E888164859398!199.entry

As for re-arranging the records in the XamDataGrid once a record has been 'dropped' on a target location, all you have to do is manipulate the data source that the XamDataGrid is bound to and remove the record from it's current location and insert it in it's new location. The XamDataGrid listens to these kinds of data source changes (assuming your data source is firing them properly) and refreshes its display to reflect the changes.

Thanks for replying.

I am not getting data in drop event which i have inserted during drag enter event.
Private Sub xdgAttachment_DragEnter(ByVal sender As Object, ByVal e As System.Windows.DragEventArgs) Handles xdgAttachment.DragEnter
'DragDrop.DoDragDrop(e.Source, e.Data, DragDropEffects.Move)
Dim dataObject As New DataObject(GetType(Record), xdgAttachment.ActiveRecord)
DragDrop.DoDragDrop(e.Source, dataObject, DragDropEffects.Move)

End Sub

Now data is set.

But whenever i am trying to fetch this i am not getting.
Private Sub xdgAttachment_Drop(ByVal sender As Object, ByVal e As System.Windows.DragEventArgs) Handles xdgAttachment.Drop Dim currentRecord As Record = e.Data.GetData(GetType(Infragistics.Windows.DataPresenter.Record))
End Sub

Here currentRecord is nothing. So what to do for that ?

Pls suggest.
