DataBind QuickBooks POS Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for QuickBooks POS 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.

When you are connecting to a local QuickBooks instance, you do not need to set any connection properties.

Requests are made to QuickBooks POS through the Remote Connector. The Remote Connector runs on the same machine as QuickBooks POS and accepts connections through a lightweight, embedded Web server. The server supports SSL/TLS, enabling users to connect securely from remote machines.

The first time you connect, you will need to authorize the Remote Connector with QuickBooks POS. See the "Getting Started" chapter of the help documentation for a guide.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with QuickBooks POS data. The QuickBooksPOSDataAdapter 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 (QuickBooksPOSConnection connection = new QuickBooksPOSConnection( "")) { QuickBooksPOSDataAdapter dataAdapter = new QuickBooksPOSDataAdapter( "SELECT ListId, AccountLimit 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[] { "AccountLimit" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "ListId"; 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 POS data. The QuickBooksPOSDataAdapter 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 (QuickBooksPOSConnection connection = new QuickBooksPOSConnection( "")) { QuickBooksPOSDataAdapter QuickBooksPOSDataAdapter1 = new QuickBooksPOSDataAdapter("SELECT ListId, AccountLimit FROM Customers", connection); DataTable table = new DataTable(); QuickBooksPOSDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "AccountLimit" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "ListId"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
