    I have been working with the Xceed DataGrid for a few days now and I love the it. However, to scroll through 1000 records is very slow. Am I doing something wrong?

    I am binding the ItemsSource to a LINQ query in the code behind.

    The following is the XAML:

    <xcdg:DataGridControl x:Name=”ListViewMeetings” HorizontalAlignment=”Stretch” VerticalAlignment=”Stretch”/>

    The following is the LINQ:

    CaselinkDataContext dc = new CaselinkDataContext();
    var cases = (
    from c in dc.Cases
    where c.asset == “N”
    from m in c.Meetings
    where m.time_341 != “”
    orderby m.date_341, m.time_341, c.case_no
    select new { m.date_341,m.time_341,m.rank_341,c.trustee_no,c.case_no,c.case_name,m.result_341,c.debt_atty,c.d_rnd,c.date_cont,c.date_closed,c.d_discharge }
    ListViewMeetings.ItemsSource = cases;

    Some “latency” is considered normal when using the “live scrolling” with the DataGridControl.

    The “latency” is caused by the time required to “generate” the next page of data rows.

    This is an area were we already made some improvements and are constantly trying to improve.
