I have subscribed to the ScrollBar_Reset event and it does return the new ViewRange. View Range update after the reset button event.

// Reset Event


void ScrollBar_Reset(object sender, EventArgs e)
{               
    NRange1DD xAxisRange = new NRange1DD(chartPrimaryXAxis.ScrollBar.BeginValue, chartPrimaryXAxis.ScrollBar.EndValue);
    //NRange1DD xAxisRange = chart.Axis(StandardAxis.PrimaryX).Scale.RulerRange;
    DateTime startdate = DateTime.FromOADate(xAxisRange.Begin);
    DateTime enddate = DateTime.FromOADate(xAxisRange.End);
    NScrollBar scrollbar = (sender as NScrollBar);
    System.Diagnostics.Debug.WriteLine("ScrollBar EndValueChanged: StartDate" + 
        DateTime.FromOADate(scrollbar.BeginValue) + "- End Date:" + DateTime.FromOADate(scrollbar.EndValue));

    System.Diagnostics.Debug.WriteLine("Horizontal Axis Begin Value" + startdate.ToString());
    System.Diagnostics.Debug.WriteLine("Horizontal Axis End Value" + enddate.ToString());
}

Does anyone know that how to track the paging view range change on reset button click?
