DataBind Zoho Books Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Zoho Books 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.

Zoho Books uses the OAuth authentication standard. To authenticate using OAuth, create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the OAuth section of the Getting Started guide in the Help documentation for an authentication guide.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Zoho Books data. The ZohoBooksDataAdapter 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 (ZohoBooksConnection connection = new ZohoBooksConnection( "OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH")) { ZohoBooksDataAdapter dataAdapter = new ZohoBooksDataAdapter( "SELECT InvoiceId, InvoiceNumber FROM INVOICES WHERE CustomerName = 'NewTech Industries'", 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[] { "InvoiceNumber" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "InvoiceId"; 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 Zoho Books data. The ZohoBooksDataAdapter 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 (ZohoBooksConnection connection = new ZohoBooksConnection( "OAuthClientId=MyOAuthClientId;OAuthClientSecret=myOAuthClientSecret;CallbackURL=https://localhost:33333;OrganizationId=MyOrganizationId;InitiateOAuth=GETANDREFRESH")) { ZohoBooksDataAdapter ZohoBooksDataAdapter1 = new ZohoBooksDataAdapter("SELECT InvoiceId, InvoiceNumber FROM INVOICES WHERE CustomerName = 'NewTech Industries'", connection); DataTable table = new DataTable(); ZohoBooksDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "InvoiceNumber" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "InvoiceId"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
