IBM Informix ADO.NET Provider

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



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

The CData ADO.NET Provider for IBM Informix 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.

Set the following properties to connect to IBM Informix

  • Server: Set this to the name of the server running IBM Informix.
  • Port: Set this to the port the IBM Informix server is listening on.
  • Database: Set this to the name of the IBM Informix database.
  • User: Set this to the username of a user allowed to access the database.
  • Password: Set this to the password of a user allowed to access the database.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with IBM Informix data. The InformixDataAdapter 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 (InformixConnection connection = new InformixConnection( "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;")) { InformixDataAdapter dataAdapter = new InformixDataAdapter( "SELECT Id, Price FROM Books WHERE Category = 'US'", 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[] { "Price" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Id"; 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 IBM Informix data. The InformixDataAdapter 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 (InformixConnection connection = new InformixConnection( "Server=10.0.1.2;Port=50000;User=admin;Password=admin;Database=test;")) { InformixDataAdapter InformixDataAdapter1 = new InformixDataAdapter("SELECT Id, Price FROM Books WHERE Category = 'US'", connection); DataTable table = new DataTable(); InformixDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Price" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
