GridView to PropertyGrid Drag Drop service

[Darren]

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,
