DataBind CockroachDB Data to the DevExpress Data Grid


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

The ADO.NET Provider for CockroachDB by CData 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 to connect to CockroachDB.

  • Server: The host name or IP address of the server.
  • Port: The port number of the CockroachDB server. If not specified, the default port is 26257.
  • Database: The name of the Cockroach database. If not specified, you connect to the user's default database.
  • User: The Cockroach DB user account used to authenticate.
  • Password: The password used to authenticate the user.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with CockroachDB data. The CockroachDBDataAdapter 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 (CockroachDBConnection connection = new CockroachDBConnection( "User=root;Password=root;Database=system;Server=localhost;Port=26257")) { CockroachDBDataAdapter dataAdapter = new CockroachDBDataAdapter( "SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'", 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[] { "ShipCity" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "ShipName"; 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 CockroachDB data. The CockroachDBDataAdapter 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 (CockroachDBConnection connection = new CockroachDBConnection( "User=root;Password=root;Database=system;Server=localhost;Port=26257")) { CockroachDBDataAdapter CockroachDBDataAdapter1 = new CockroachDBDataAdapter("SELECT ShipName, ShipCity FROM Orders WHERE ShipCountry = 'USA'", connection); DataTable table = new DataTable(); CockroachDBDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "ShipCity" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "ShipName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
