IBM DB2 ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with IBM DB2.



Use the CData ADO.NET Provider for DB2 with the DevExpress Windows Forms and Web controls to provide DB2 data to a chart.

The CData ADO.NET Provider for DB2 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.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with DB2 data. The DB2DataAdapter 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 (DB2Connection connection = new DB2Connection( "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;")) { DB2DataAdapter dataAdapter = new DB2DataAdapter( "SELECT Orders.Freight, Customers.ContactName FROM Customers INNER JOIN Orders ON Customers.CustomerId=Orders.CustomerId", 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[] { "Freight" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "OrderName"; 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 DB2 data. The DB2DataAdapter 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 (DB2Connection connection = new DB2Connection( "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;")) { DB2DataAdapter DB2DataAdapter1 = new DB2DataAdapter("SELECT Orders.Freight, Customers.ContactName FROM Customers INNER JOIN Orders ON Customers.CustomerId=Orders.CustomerId", connection); DataTable table = new DataTable(); DB2DataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Freight" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "OrderName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
