DataBind Smaregi Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Smaregi 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.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Smaregi data. The SmaregiDataAdapter 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 (SmaregiConnection connection = new SmaregiConnection( "ContractId=mycontractid;AccessToken=myaccesstoken;")) { SmaregiDataAdapter dataAdapter = new SmaregiDataAdapter( "SELECT ProductName, Description FROM Products", 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[] { "Description" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "ProductName"; 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 Smaregi data. The SmaregiDataAdapter 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 (SmaregiConnection connection = new SmaregiConnection( "ContractId=mycontractid;AccessToken=myaccesstoken;")) { SmaregiDataAdapter SmaregiDataAdapter1 = new SmaregiDataAdapter("SELECT ProductName, Description FROM Products", connection); DataTable table = new DataTable(); SmaregiDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Description" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "ProductName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
