GridViewDataTextColumn productColumn = new GridViewDataTextColumn();
productColumn.FieldName = "QuantityPerUnit";
productColumn.Settings.AllowDragDrop = DevExpress.Utils.DefaultBoolean.True;

csharp

@Html.DevExpress().GridView(settings => {
    settings.Name = "grid";
    settings.SettingsBehavior.AllowDragDrop = DevExpress.Utils.DefaultBoolean.False;
