    I've implemented Drag & Drop into a RadGridView. The DataObject I'm dropping is a string.

    I need to detect whether the string is dropped into a Cell (in which case it will add the string to the cell value) or elsewhere on the RadGridView (where a new row will be created).

    private void OnDropAttributes(object sender, Telerik.Windows.DragDrop.DragEventArgs args)
            {
                DataObject data = (args.Data as DataObject);

                ...?

    Hello Ed, 

    You can get the target cell by using the args.OriginalSource property:
    var cell = args.OriginalSource as GridViewCell ?? (args.OriginalSource as FrameworkElement).ParentOfType<GridViewCell>();


    Note however that updating the value in the cell visual element is not recommended as it can have unexpected results when scrolling due to the Row Virtualization. Consider updating the bound property in the business object instead.
