Use the CData ADO.NET Provider for QuickBooks Online with the DevExpress Windows Forms and Web controls to provide QuickBooks Online data to a chart.
The CData ADO.NET Provider for QuickBooks Online 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.
QuickBooks Online uses the OAuth authentication standard. OAuth requires the authenticating user to log in through the browser. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can obtain your own by registering an app with Intuit. Additionally, if you want to connect to sandbox data, set UseSandbox to true.
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 QuickBooks Online data. The QuickBooksOnlineDataAdapter 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 (QuickBooksOnlineConnection connection = new QuickBooksOnlineConnection(
"InitiateOAuth=GETANDREFRESH")) {
QuickBooksOnlineDataAdapter dataAdapter = new QuickBooksOnlineDataAdapter(
"SELECT DisplayName, Balance FROM Customers", 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[] { "Balance" });
series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
series.ArgumentDataMember = "DisplayName";
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 QuickBooks Online data. The QuickBooksOnlineDataAdapter 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 (QuickBooksOnlineConnection connection = new QuickBooksOnlineConnection(
"InitiateOAuth=GETANDREFRESH"))
{
QuickBooksOnlineDataAdapter QuickBooksOnlineDataAdapter1 = new QuickBooksOnlineDataAdapter("SELECT DisplayName, Balance FROM Customers", connection);
DataTable table = new DataTable();
QuickBooksOnlineDataAdapter1.Fill(table);
DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
WebChartControl1.Series.Add(series);
series.DataSource = table;
series.ValueDataMembers.AddRange(new string[] { "Balance" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "DisplayName";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
