Question

Currently I have a DataGridView in my app which I fill from my Linq-to-SQL classes like so …

    /// <summary>
    /// Delegate to update datagrid, fixes threading issue
    /// </summary>
    private void updateInfo()
    {
        // Linq to datagridview; display all
        var query = from n in dbh.Items select n;
        itemDataGridView.DataSource = query.ToList();
    }

So the problem with this is every time I add new information and run this refresh, the focus of the table changes, meaning if I’m on one row it will switch me to an another one.
And there is an event tied to the change of row so this causes this event to run while the list keeps refreshing.

I don’t but I remember before switching to Linq-to-SQL bounded DataGridView there was a TableAdapter formed, and instead of altering data in the DB you would just insert using this TableAdapter which would automatically refresh the DataGridView in the proper way.

So I’m wondering if there is some other way I should be doing this to each that smooth refresh?

This doesn’t sound like a L2S issue to me. This sounds more like an issue with whatever grid you are using. All L2S does is to supply your grid with data. It makes sense to me that the current row of the grid would change after a refresh. Is it possible for you to disable the grid, set the current row to be what you want, and then enable the grid? I’ve done this in the past.
