Use the CData ADO.NET Provider for Excel Services with the DevExpress Windows Forms and Web controls to provide Excel Services data to a chart.

The CData ADO.NET Provider for Excel Services implements standard ADO.NET data access components that can be used with third-party controls. The standard ADO.NET process for databinding can be followed to enable bidirectional access to live data from UI controls. In this article we show how to use the CData components to databind to the DevExpress Windows Forms and Web controls; you will databind to a chart that displays current data.

Additionally, the Library property must be set to a valid SharePoint Document Library and the File property must be set to a valid .xlsx file in the indicated Library.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Excel Services data. The ExcelServicesDataAdapter binds to the Series property of the chart control. The Diagram property of the control defines the x- and y-axes as the column names.

using (ExcelServicesConnection connection = new ExcelServicesConnection( "URL=https://myorg.sharepoint.com;User=admin@myorg.onmicrosoft.com;Password=password;File=Book1.xlsx;")) { ExcelServicesDataAdapter dataAdapter = new ExcelServicesDataAdapter( "SELECT Name, AnnualRevenue FROM Account", connection); DataTable table = new DataTable(); dataAdapter.Fill(table); DevExpress.XtraCharts.Series series = new DevExpress.XtraCharts.Series(); chartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "AnnualRevenue" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = DevExpress.XtraCharts.ScaleType.Numerical; chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }

Web Controls

The code below shows how to populate a DevExpress Web control with Excel Services data. The ExcelServicesDataAdapter binds to the Series property of the chart; the Diagram property defines the x- and y-axes as the column names.

using DevExpress.XtraCharts; using (ExcelServicesConnection connection = new ExcelServicesConnection( "URL=https://myorg.sharepoint.com;User=admin@myorg.onmicrosoft.com;Password=password;File=Book1.xlsx;")) { ExcelServicesDataAdapter ExcelServicesDataAdapter1 = new ExcelServicesDataAdapter("SELECT Name, AnnualRevenue FROM Account", connection); DataTable table = new DataTable(); ExcelServicesDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "AnnualRevenue" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
