DataBind Evernote Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Evernote 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.

Evernote uses the OAuth authentication standard. You can use the embedded OAuth application to connect without setting any connection properties. Alternatively, you can create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Evernote data. The EvernoteDataAdapter 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 (EvernoteConnection connection = new EvernoteConnection( "OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;")) { EvernoteDataAdapter dataAdapter = new EvernoteDataAdapter( "SELECT Title, Author FROM Notes WHERE Guid = ab26f704-5edf-4a9f-9e4c-8da893a4acd8", 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[] { "Author" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Title"; 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 Evernote data. The EvernoteDataAdapter 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 (EvernoteConnection connection = new EvernoteConnection( "OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;")) { EvernoteDataAdapter EvernoteDataAdapter1 = new EvernoteDataAdapter("SELECT Title, Author FROM Notes WHERE Guid = ab26f704-5edf-4a9f-9e4c-8da893a4acd8", connection); DataTable table = new DataTable(); EvernoteDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Author" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Title"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
