DataBind DocuSign Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for DocuSign 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.

To connect to DocuSign, set the following connection properties:

  • UseSandbox: indicates whether current user account is sandbox or not (FALSE by default)
  • AccountId (optional): set it in the connection string if you have access to multiple Account Ids

Authenticating to DocuSign

DocuSign uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Help documentation more information.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with DocuSign data. The DocuSignDataAdapter 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 (DocuSignConnection connection = new DocuSignConnection( "OAuthClientId=MyClientId; OAuthClientSecret=MyClientSecret; CallbackURL=http://localhost:33333; InitiateOAuth=GETANDREFRESH")) { DocuSignDataAdapter dataAdapter = new DocuSignDataAdapter( "SELECT DocumentId, DocumentName FROM Documents WHERE DocumentName = 'TPSReport'", 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[] { "DocumentName" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "DocumentId"; 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 DocuSign data. The DocuSignDataAdapter 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 (DocuSignConnection connection = new DocuSignConnection( "OAuthClientId=MyClientId; OAuthClientSecret=MyClientSecret; CallbackURL=http://localhost:33333; InitiateOAuth=GETANDREFRESH")) { DocuSignDataAdapter DocuSignDataAdapter1 = new DocuSignDataAdapter("SELECT DocumentId, DocumentName FROM Documents WHERE DocumentName = 'TPSReport'", connection); DataTable table = new DataTable(); DocuSignDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "DocumentName" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "DocumentId"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
