DataBind DigitalOcean Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for DigitalOcean 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.

DigitalOcean uses OAuth 2.0 authentication. To authenticate using OAuth, you can use the embedded credentials or register an app with DigitalOcean.

See the Getting Started guide in the CData driver documentation for more information.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with DigitalOcean data. The DigitalOceanDataAdapter 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 (DigitalOceanConnection connection = new DigitalOceanConnection( "")) { DigitalOceanDataAdapter dataAdapter = new DigitalOceanDataAdapter( "SELECT Id, Name FROM Droplets", 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[] { "Name" }); 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 DigitalOcean data. The DigitalOceanDataAdapter 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 (DigitalOceanConnection connection = new DigitalOceanConnection( "")) { DigitalOceanDataAdapter DigitalOceanDataAdapter1 = new DigitalOceanDataAdapter("SELECT Id, Name FROM Droplets", connection); DataTable table = new DataTable(); DigitalOceanDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Name" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
