Hello Tom,

May I ask you to share what you are trying to achieve? A screenshot would be really helpful!

Looking forward to hearing from you!

My bussines object contains some properties and for example the driver property (another class). My so called drivers all already visualized by the treeview. I would like to drag driver from the treeview to the corresponding property of that business object in the RadPropertyGrid.

Is this clear enough?

Nothing special.

I have the problem how to identify the property, where I have dropped dragged data.

Something like destinationItem for a RadTreeView:

private void OnDrop(object sender, Telerik.Windows.DragDrop.DragEventArgs e)
        {
            if (this.isTreeSource)
            {
                var data = DragDropPayloadManager.GetDataFromObject(e.Data, "DraggedData");

                this.sourceItems.Remove(data);
            }

            if (e.Effects != DragDropEffects.None)
            {
                var destinationItem = (e.OriginalSource as FrameworkElement).ParentOfType<RadTreeViewItem>();
                var dropDetails = DragDropPayloadManager.GetDataFromObject(e.Data, "DropDetails") as DropIndicationDetails;
                var data = DragDropPayloadManager.GetDataFromObject(e.Data, "DraggedData");

                if (destinationItems != null)
                {
                    int dropIndex = dropDetails.DropIndex >=
                        destinationItems.Count ? destinationItems.Count : dropDetails.DropIndex < 0 ? 0 : dropDetails.DropIndex;

                    this.destinationItems.Insert(dropIndex, data);
                }
            }
        }

How can I find the destination property item? My properties are populated manually.

Thank you very much.

Hello Tomas,

You can get it by assigning a DropHandler to the Property Grid and get the e.OriginalSource.ParentOfType<PropertyGridField>() item. 

Hope this helps! 

All the best,
