Drag&Drop issue

[Raul]

Hello,

when in edit mode with a row validation error it is still possible to perform Drag&Drop operations. They are not visible while performing the Drop, but the rows will be sorted just after clearing the row validation error.

Greeting

Hi Raul,

I suppose that you are using our RowReorderBehaviour for reordering the rows. If yes, you can stop the drag&drop operation when the grid is in edit mode. In order to achieve this, you can use a boolean flag in OnDragInitialize method of the behaviour like so:

private void OnDragInitialize(object sender, DragInitializeEventArgs e)

       {

           if (flag)

           {

               return;

           }

           var sourceRow = e.OriginalSource as GridViewRow ?? (e.OriginalSource as FrameworkElement).ParentOfType<GridViewRow>();

           if (sourceRow != null && sourceRow.Name != "PART_RowResizer")

           {
                           .
                           . 
                           .

You can set the flag in GridView's BeginningEdit and RowEditEnded events.

Let me know if you need further assistance on this.
