If i do as you say, then it does not "ZoomIn" again and calculate view range value is returned as ResetMode = View.

primaryXAxis.PagingView.Enabled = false;

Hi Niranjan,

The reset button will simply disable the paging view - however obviosly this is done after the event is fired - to simulate that just use:

someAxis.PagingView.Enabled = false;

before you calculate the control. Hope this helps...

I have modified code as you suggested but it is returning last zoomIn Range rather than reset range.

void ScrollBar_Reset(object sender, EventArgs e)
{
    chartControl.Document.Calculate();
    chartControl.RecalcLayout();            
    //chartControl.Document.RecalcLayout(chartControl.View.Context);

    ////dateTimeScale
    //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);
    //DateTime startdate = DateTime.FromOADate(scrollbar.BeginValue);
    //DateTime enddate = DateTime.FromOADate(scrollbar.EndValue);
    DateTime startdate = DateTime.FromOADate(chartPrimaryXAxis.PagingView.ViewRange.Begin);
    DateTime enddate = DateTime.FromOADate(chartPrimaryXAxis.PagingView.ViewRange.End);
    System.Diagnostics.Debug.WriteLine("On ScrollBar Reset StartDate:" + startdate.ToString() + " - EndDate:" + enddate.ToString());
    //UpdateResultsViewReloadState();
}

But it result same as before.

Hi Niranjan,

You can try to recalculate the control:

nChartControl1.Document.Calculate();
nChartControl1.RecalcLayout();

and then get the new range.

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?
