DataBind Sybase Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Sybase 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.

To authenticate with Sybase, set User and Password. Additionally, set IntegratedSecurity; to true to use Windows authentication otherwise, Sybase authentication is used. Set the Server and Database properties. To secure connections with TLS/SSL, set Encrypt to true.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Sybase data. The SybaseDataAdapter 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 (SybaseConnection connection = new SybaseConnection( "User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;")) { SybaseDataAdapter dataAdapter = new SybaseDataAdapter( "SELECT Id, ProductName FROM Products WHERE ProductName = Konbu", 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[] { "ProductName" }); 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 Sybase data. The SybaseDataAdapter 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 (SybaseConnection connection = new SybaseConnection( "User=myuser;Password=mypassword;Server=localhost;Database=mydatabase;")) { SybaseDataAdapter SybaseDataAdapter1 = new SybaseDataAdapter("SELECT Id, ProductName FROM Products WHERE ProductName = Konbu", connection); DataTable table = new DataTable(); SybaseDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "ProductName" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
