DataBind SAP Fieldglass Data to the DevExpress Data Grid

The ADO.NET Provider for SAP Fieldglass by CData incorporates conventional ADO.NET data access components compatible with third-party controls. You can adhere to the standard ADO.NET data binding procedures to establish two-way access to real-time data through UI controls. This article will demonstrate the utilization of CData components for data binding with DevExpress UI Controls (Windows Forms and Web controls), specifically binding to a chart that visualizes live data.

To authenticate, specify the Username, Password, APIKey, and EnvironmentURL connection properties.

To obtain an APIKey, log in to the SAP API Business Hub and click on Get API Key.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with SAP Fieldglass data. The SAPFieldglassDataAdapter 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 (SAPFieldglassConnection connection = new SAPFieldglassConnection(
"EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH;")) {
 SAPFieldglassDataAdapter dataAdapter = new SAPFieldglassDataAdapter(
 "SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'", 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[] { "Category" });
 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 SAP Fieldglass data. The SAPFieldglassDataAdapter 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 (SAPFieldglassConnection connection = new SAPFieldglassConnection(
"EnvironmentURL='https://myinstance.com';Username=myuser;Password=mypassword;APIKey=xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx;InitiateOAuth=GETANDREFRESH;"))
{
 SAPFieldglassDataAdapter SAPFieldglassDataAdapter1 = new SAPFieldglassDataAdapter("SELECT Id, Category FROM AuditTrails WHERE Company = 'CData'", connection);
 DataTable table = new DataTable();
 SAPFieldglassDataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "Category" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "Id";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
