DataBind IBM Informix Data to the DevExpress Data Grid

The CData ADO.NET Provider for IBM Informix incorporates conventional ADO.NET data access components compatible with third-party controls. You can adhere to the standard ADO.NET data binding procedures to establish two-way access to real-time data through UI controls. This article will demonstrate the utilization of CData components for data binding with DevExpress UI Controls (Windows Forms and Web controls), specifically binding to a chart that visualizes live 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;
}
