DataBind SAP HANA Data to the DevExpress Data Grid


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

The ADO.NET Provider for SAP HANA 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.

Set the Server, Database and Port properties to specify the address of your SAP Hana database to interact with. Set the User and the Password properties to authenticate to the server.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with SAP HANA data. The SAPHANADataAdapter 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 (SAPHANAConnection connection = new SAPHANAConnection( "User=system;Password=mypassword;Server=localhost;Database=systemdb;")) { SAPHANADataAdapter dataAdapter = new SAPHANADataAdapter( "SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'", 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[] { "OwnerId" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Name"; 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 data. The SAPHANADataAdapter 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 (SAPHANAConnection connection = new SAPHANAConnection( "User=system;Password=mypassword;Server=localhost;Database=systemdb;")) { SAPHANADataAdapter SAPHANADataAdapter1 = new SAPHANADataAdapter("SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'", connection); DataTable table = new DataTable(); SAPHANADataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "OwnerId" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
