DataBind MailChimp Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for MailChimp 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.

You can set the APIKey to the key you generate in your account settings, or, instead of providing your APIKey, you can use the OAuth standard to authenticate the application. OAuth can be used to enable other users to access their own data. To authenticate using OAuth, you will need to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL by registering an app with MailChimp.

See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with MailChimp data. The MailChimpDataAdapter 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 (MailChimpConnection connection = new MailChimpConnection( "APIKey=myAPIKey;")) { MailChimpDataAdapter dataAdapter = new MailChimpDataAdapter( "SELECT Name, Stats_AvgSubRate FROM Lists", 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[] { "Stats_AvgSubRate" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Name"; 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 MailChimp data. The MailChimpDataAdapter 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 (MailChimpConnection connection = new MailChimpConnection( "APIKey=myAPIKey;")) { MailChimpDataAdapter MailChimpDataAdapter1 = new MailChimpDataAdapter("SELECT Name, Stats_AvgSubRate FROM Lists", connection); DataTable table = new DataTable(); MailChimpDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Stats_AvgSubRate" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
