Drag and Drop Row

[Jay]

I'm following the example in the attached file here to drag and drop rows. In the PreviewDragDrop() event, the example casts e.DragInstance to a GridDataRowElement.

var rowElement = e.DragInstance as GridDataRowElement;
if (rowElement == null)
    return;

However, I never get a GridDataRowElement, I always get a SnapshotDragItem, so rowElement is always null.

How do I get the row element?

Hello Jay,

Thank you for writing.

I have tested the project in the mentioned article, however, the type of the DragInstance in the dragDropService_PreviewDragDrop event handler is GridDataRowElement, not SnapshotDragItem. However, on other cases of drag and drop (like row reordering for example) it is possible that you end up with this type. In was recently introduced to help us improving some features in the control. Here is how to get the dragged object from the snapshot item:

GridDataRowElement row = ((SnapshotDragItem)e.DragInstance).Item as GridDataRowElement;

I hope that you find this information useful.

All the best,

That works beautifully.

Thanks a lot Stefan.
