DataBind Access Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Access 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 connect, set the DataSource property to the path to the Access database.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Access data. The AccessDataAdapter 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 (AccessConnection connection = new AccessConnection( "DataSource=C:\MyDB.accdb;")) { AccessDataAdapter dataAdapter = new AccessDataAdapter( "SELECT Orders.Freight, Customers.ContactName FROM Customers INNER JOIN Orders ON Customers.CustomerId=Orders.CustomerId", 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[] { "Freight" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "OrderName"; 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 Access data. The AccessDataAdapter 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 (AccessConnection connection = new AccessConnection( "DataSource=C:\MyDB.accdb;")) { AccessDataAdapter AccessDataAdapter1 = new AccessDataAdapter("SELECT Orders.Freight, Customers.ContactName FROM Customers INNER JOIN Orders ON Customers.CustomerId=Orders.CustomerId", connection); DataTable table = new DataTable(); AccessDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Freight" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "OrderName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
