Create Drag And Drop Operation Between DevExpress GridControl And Custom WPF UI | Saatody | Amit Padhiyar

 Today i will create Drag And Drop Operation. Actually, DevExpress GridControl support Drag and Drop in Views (TreeListView, TabelView, and CardView). But I am trying to drag GridControl row and drop on my custom UI. Here I will write about Drag and Drop with two clipboard operations. Drag Copy And Drop Drag Cut And Drop First set these two properties on GridControl And View (TreeListView, CardView, TableView). GridControl.AllowDrop = true; GridView.AllowDragDrop = true; GridView.AllowDrop = true; GridView.ShowDragDropHint = false; Due to ShowDragDropHint false, The hint will be disable and only cursor will change during DnD (Drag and Drop). First we create Drag Copy And Drop it is too simple to create drag and drop with copy data or element. We just prevent drag leave events using e.Handled = true. GridControl side coding GridControl.AllowDrop = true; GridView.AllowDragDrop = true; GridView.AllowDrop = true; GridView.ShowDragDropHint = false; GridView.StartRecordDrag += (sender, e) =
