I having a hard time getting the grid to refresh after a drag and drop on a row. I have a "displayOrder" column where on drop, it renumbers the column and save to the db. That works fine.  The grid is bound to an observable collection so it should reflect immediately.  Here's some code:

private

 

 

void RowReorder_AfterDrop() 
{

 

 

 

short

 

 

newIdx = 1;

 

foreach (var item in oSupplyRules)
{
item.DisplayOrder = newIdx++;
}

}

private void RowReorderBehavior_DragEnded(object sender, DragEndedEventArgs e)
{

 

 

 

 

 

MessageBox.Show(string.Format("Drop complete! Index: {0}"

, e.DestinationIndex));

 

var items = ((IList)e.SourceGrid.ItemsSource); 

 

 

 

 

 

using

(e.SourceGrid.Items.DeferRefresh())

{

 

foreach (var item in e.DraggedItems)

items.Remove(item); 

}

 

 

 

foreach (var item in e.DraggedItems)
{

 

if

(e.DestinationIndex < items.Count)

items.Insert(e.DestinationIndex, item); 

}

 

 

 

 

else

 

 

{

items.Add(item);

}

}

RowReorder_AfterDrop();

}

 

 

DM.Context.SubmitChanges(); e.SourceGrid.Rebind();}

Any help would be GREATLY appreciated!

Hello UGH!!,

 Unfortunately we cannot tell just looking at this code what's going on. Do you have the same problem using plain ListBox or this is just with RadGridView?

All the best,
