Chart X-Axis ToOADate Date Label Issue

[Sir]

Hi, I have telerik ver 2009.02.0817.20

I have an area chart where my x-axis labels are dates using .ToOADate().
I found the code example on your site and it was working at one point early on.
I can't figure out for the life of me now what is wrong.
No matter what I do, the x-axis date lables are all showing up as the .ToOADate():  i.e. the label is "40096" instead of "10/10/2009".
The chartDay.Date, this.ChartStartDate, & this.ChartEndDate are all valid dates and all set to exactly midnight.
Here is my code, where am I going wrong????

<RadControl:RadChart ID="RadChartControl" SeriesOrientation="Vertical" runat="server" Skin="Web20" Height="225px" Width="777px" Visible="true" ChartTitle-Visible="false"></RadControl:RadChart>

            this.RadChartControl.ChartTitle.TextBlock.Text = "Loan Event Average Response Time by Day";
            this.RadChartControl.Series.Clear();

            if (chartData != null && chartData.Count > 0)
            {
                Telerik.Charting.ChartSeries chartSeries = new Telerik.Charting.ChartSeries();
                chartSeries.Name = "Loan Event Average Response Time";

Issue Solved...
For some reason, the order of the code lines makes a big difference.
I moved the .AddRange command under the other PlotArea.XAxis commands, and all is well in the world.

            this.RadChartControl.PlotArea.XAxis.LayoutMode = Telerik.Charting.Styles.ChartAxisLayoutMode.Inside;
            this.RadChartControl.PlotArea.XAxis.AutoScale = false;
            this.RadChartControl.PlotArea.XAxis.IsZeroBased = false;
            this.RadChartControl.PlotArea.XAxis.Appearance.ValueFormat = Telerik.Charting.Styles.ChartValueFormat.ShortDate;
            this.RadChartControl.PlotArea.XAxis.Appearance.CustomFormat = "MM/dd/yyyy";
            this.RadChartControl.PlotArea.XAxis.Appearance.MajorGridLines.Visible = false;
            this.RadChartControl.PlotArea.XAxis.Appearance.LabelAppearance.RotationAngle = (float)45;
            this.RadChartControl.PlotArea.XAxis.Appearance.LabelAppearance.Position.AlignedPosition = Telerik.Charting.Styles.AlignedPositions.Top;
            this.RadChartControl.PlotArea.XAxis.Appearance.TextAppearance.TextProperties.Font = new System.Drawing.Font("Ariel", 8);
            this.RadChartControl.PlotArea.YAxis.IsZeroBased = false;

            const double dayStep = 1;
            //const double hourStep = 1 / 24.0;
            //const double minuteStep = hourStep / 60;
            //const double fiveMinuteStep = minuteStep * 5;
            this.RadChartControl.PlotArea.XAxis.AddRange(this.ChartStartDate.ToOADate(), this.ChartEndDate.ToOADate(), dayStep);

 

The above now works.
