A little dramatic maybe, but I've just finished my pass on the "UI Polish"
and only one things remains (well, I guess I haven't finished then!)

Vertical Scrollbar position.  Doh!
Part of my code clears a Node's nodes, then rebuilds them all.  When this
happens, the scrollbar position is not restored (expected - I'm happy to do
it.. if I can!) and I don't see how I can do that.  I have checked the docs,
google, friends, etc.  No love.  Is it possible?

Teach me, wise one(s)...

Thanks for the post!

This doesn't work. Not for my case.  I need to get and restore the scrollbar
position.

I had a similiar issue in a datagrid which I had to remember the value
and find it again.  The scroll isn't readily available so I had to
override the normal grid to make the scroll accessible...

// When the frmEditShipment form closes, it will set the
// lastEvent and lastRecord strings so that we can
// this form can autonavigate to the record and re-select it.
// this way, even having several records open you can
// close anyone and be brought to it's matching line entry.

if(lastEvent == "Edit")
{
    //lastEvent = "";
    runData(true);
    // runData has reset the grid, due to rebinding
    // now set the grid back to the same location
    // the BindingManagerBase gives you a link between
    // the displayed records and the dataset records.
    // use this to scroll to and select the row
    BindingManagerBase bmb =
dgRec.BindingContext[dgRec.DataSource,"trucks"];
    for(int i = 0; i < bmb.Count;i++)
    {
        // use the Manager as a cursor and move forward through it.
        bmb.Position = i;
        // check each row's barcode to see if it's the right one
        DataRow dr = ((DataRowView)bmb.Current).Row;
        if(lastRecord == Convert.ToString(dr["barCodeNumber"]))
        {
            // had to override the grid to get access to the scroll
            // also had to use the overridden object as the grid,
            // instead of the default Forms.DataGrid
            // It now exists in MyDataGrid.cs
            dgRec.ScrollToRow(i);
            dgRec.CurrentCell = new DataGridCell(i,1);
            dgRec.Select(i);
            break;  // don't look anymore
        }
    }

}


Maybe something similiar will help you get it working...

public class MyDataGrid : DataGrid
{
    public MyDataGrid()
    {
        //
        // TODO: Add constructor logic here
        // This class is dirived from DataGrid to all
        // the private method GridVScrolled to be
        // accessed, allowing us to scroll the grid
        // back to it's last row after a refresh
        // of the data and a rebinding
        //

    }
    public void ScrollToRow(int row)
    {
        if(this.DataSource != null)
        {
            this.GridVScrolled(this,new
ScrollEventArgs(ScrollEventType.LargeIncrement,row));
        }
    }
}
