Windows Forms Controls

The code below shows how to populate a DevExpress chart with Oracle Sales Cloud data. The OracleSalesCloudDataAdapter 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 (OracleSalesCloudConnection connection = new OracleSalesCloudConnection( "HostURL=https://my.host.oraclecloud.com; Username=abc123; Password=abcdef;")) { OracleSalesCloudDataAdapter dataAdapter = new OracleSalesCloudDataAdapter( "SELECT OptyId, Name FROM Opportunities", 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[] { "Name" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "OptyId"; 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 Oracle Sales Cloud data. The OracleSalesCloudDataAdapter binds to the Series property of the chart; the Diagram property defines the x- and y-axes as the column names.
