DataBind SAP HANA XS Advanced Data to the DevExpress Data Grid

Use the CData ADO.NET Provider for SAP HANA XS Advanced with the DevExpress Windows Forms and Web controls to provide SAP HANA XS Advanced data to a chart.

The CData ADO.NET Provider for SAP HANA XS Advanced 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.

SAP HANA XSA uses the OAuth authentication standard. Before connecting, it is necessary to establish an SAP HANA XSA OData Service. See the OAuth section in the Help documentation for a guide.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with SAP HANA XS Advanced data. The SAPHanaXSADataAdapter 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 (SAPHanaXSAConnection connection = new SAPHanaXSAConnection( "OAuthClientID=my-ouath-client-id;OAuthClientSecret=my-oauth-client-secret;URL=https://hxehost:51027/euro.xsodata;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH")) { SAPHanaXSADataAdapter dataAdapter = new SAPHanaXSADataAdapter( "SELECT , FROM WHERE = ''", 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[] { "" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = ""; 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 HANA XS Advanced data. The SAPHanaXSADataAdapter 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 (SAPHanaXSAConnection connection = new SAPHanaXSAConnection( "OAuthClientID=my-ouath-client-id;OAuthClientSecret=my-oauth-client-secret;URL=https://hxehost:51027/euro.xsodata;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH")) { SAPHanaXSADataAdapter SAPHanaXSADataAdapter1 = new SAPHanaXSADataAdapter("SELECT , FROM WHERE = ''", connection); DataTable table = new DataTable(); SAPHanaXSADataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = ""; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
