    using the Drag Drop Service i cant get the e.HitTarget to return true no matter what propertygrid reference i use must be missing something here.

    basically i just want to recreate the propertygrid items when a GridDataRowElement is dragged onto a propertygrid.

     

    private void svc_PreviewDragOver(object sender, RadDragOverEventArgs e)
    {

    if (e.DragInstance is GridDataRowElement)
    {
    e.CanDrop = e.HitTarget is PropertyGridElement;
    }
    }

    Hello Darren,

    Thank you for writing. 

    If your RadPropertyGrid is populated with items, note that the HitTaret is supposed to be the visual item element. You can find below a sample code snippet demonstrating how to allow dragging over the items in RadPropertyGrid:
    RadDragDropService svc = this.radGridView1.GridViewElement.GetService<RadDragDropService>();
    svc.PreviewDragOver += DragDropService_PreviewDragOver;
    this.radPropertyGrid1.ItemFormatting += radPropertyGrid1_ItemFormatting;

    private void radPropertyGrid1_ItemFormatting(object sender, PropertyGridItemFormattingEventArgs e)
    {
        e.VisualElement.AllowDrop = true;
    }
     
    private void DragDropService_PreviewDragOver(object sender, RadDragOverEventArgs e)
    {
        if (e.HitTarget is PropertyGridItemElement)
        {
            e.CanDrop = true;
        }
    }

    I hope this information helps. Should you have further questions I would be glad to help.

    Regards,
