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.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with QuickBase data. The QuickBaseDataAdapter 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 (QuickBaseConnection connection = new QuickBaseConnection( "User=user@domain.com;Password=password;Domain=myinstance.quickbase.com;ApplicationToken=bwkxrb5da2wn57bzfh9xn24")) { QuickBaseDataAdapter dataAdapter = new QuickBaseDataAdapter( "SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = '100'", 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[] { "Column1" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Id"; 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 QuickBase data. The QuickBaseDataAdapter 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 (QuickBaseConnection connection = new QuickBaseConnection( "User=user@domain.com;Password=password;Domain=myinstance.quickbase.com;ApplicationToken=bwkxrb5da2wn57bzfh9xn24")) { QuickBaseDataAdapter QuickBaseDataAdapter1 = new QuickBaseDataAdapter("SELECT Id, Column1 FROM SampleTable_1 WHERE Column2 = '100'", connection); DataTable table = new DataTable(); QuickBaseDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Column1" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
