DataBind Google Analytics Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Google Analytics 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.

Google uses the OAuth authentication standard. To access Google APIs on behalf on individual users, you can use the embedded credentials or you can register your own OAuth app.

OAuth also enables you to use a service account to connect on behalf of users in a Google Apps domain. To authenticate with a service account, you will need to register an application to obtain the OAuth JWT values.

In addition to the OAuth values, set Profile to the profile you want to connect to. This can be set to either the Id or website URL for the Profile. If not specified, the first Profile returned will be used.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Google Analytics data. The GoogleAnalyticsDataAdapter 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 (GoogleAnalyticsConnection connection = new GoogleAnalyticsConnection( "Profile=MyProfile;InitiateOAuth=GETANDREFRESH")) { GoogleAnalyticsDataAdapter dataAdapter = new GoogleAnalyticsDataAdapter( "SELECT Browser, Sessions FROM Traffic", 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[] { "Sessions" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Browser"; 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 Google Analytics data. The GoogleAnalyticsDataAdapter 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 (GoogleAnalyticsConnection connection = new GoogleAnalyticsConnection( "Profile=MyProfile;InitiateOAuth=GETANDREFRESH")) { GoogleAnalyticsDataAdapter GoogleAnalyticsDataAdapter1 = new GoogleAnalyticsDataAdapter("SELECT Browser, Sessions FROM Traffic", connection); DataTable table = new DataTable(); GoogleAnalyticsDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Sessions" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Browser"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
