Chart DataSource and code data - Why doesn't this work

[Jon]

Hi..
I'm trying to bind 1 datasource and add another series programmatically.
But my code to add  new series does not show up. If I remove the datasource it does. 
What's wrong with this?   thx!

   SQL = "SELECT  *  TEMP_HUMID_ANALYSIS ";
            


            this.chartTEMP_HUMID.DataSource = new SqlDataSource(DC.Connection.ConnectionString, SQL);
            
// THIS WORKS


// THIS DOES NOT nothing.. if I remvoe the above it works
            // Red Series
            ChartSeries serie1 = new ChartSeries();
            serie1.Name = "Red";
            serie1.Type = ChartSeriesType.Area;
            serie1.YAxisType = ChartYAxisType.Secondary;


            serie1.Appearance.Border.Visible = false;
            serie1.Appearance.FillStyle.FillType = Telerik.Reporting.Charting.Styles.FillType.Hatch;
            serie1.Appearance.FillStyle.MainColor = System.Drawing.Color.Red;
            serie1.Appearance.LegendDisplayMode = ChartSeriesLegendDisplayMode.SeriesName;


            Telerik.Reporting.Charting.ChartSeriesItem item = new Telerik.Reporting.Charting.ChartSeriesItem();
            
            item.XValue = 70;
            item.YValue = 0;


            serie1.AddItem(item);




            item = new Telerik.Reporting.Charting.ChartSeriesItem();


            item.XValue = 68.7;
            item.YValue = 82;


            serie1.AddItem(item);




            item = new Telerik.Reporting.Charting.ChartSeriesItem();


            item.XValue = 80;
            item.YValue = 55;


            serie1.AddItem(item);




            item = new Telerik.Reporting.Charting.ChartSeriesItem();


            item.XValue = 83.3;
            item.YValue = 0;


            serie1.AddItem(item);




            this.chartTEMP_HUMID.Series.Add(serie1);

Hi Jon,

You cannot add manual series when the chart is databound, in fact the NeedDataSource event which would be the correct place to do such a thing, would not even fire when you have the DataSource property of the chart set. You can either create all needed series in the designer and bind them, or create the chart series and items entirely programmatically, without using the DataSource property of the chart.

All the best,
