DataBind Amazon Marketplace Data to the DevExpress Data Grid


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

The ADO.NET Provider for Amazon Marketplace 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.

To connect to the Amazon Marketplace Webservice (MWS), AWSAccessKeyId, MWSAuthToken, AWSSecretKey and SellerId are required. You can optionally set the Marketplace property. For more information on obtaining values for these properties, refer to the Help documentation.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Amazon Marketplace data. The AmazonMarketplaceDataAdapter 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 (AmazonMarketplaceConnection connection = new AmazonMarketplaceConnection( "AWS Access Key Id=myAWSAccessKeyId;AWS Secret Key=myAWSSecretKey;MWS Auth Token=myMWSAuthToken;Seller Id=mySellerId;Marketplace=United States;")) { AmazonMarketplaceDataAdapter dataAdapter = new AmazonMarketplaceDataAdapter( "SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True", 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[] { "OrderStatus" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "AmazonOrderId"; 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 Amazon Marketplace data. The AmazonMarketplaceDataAdapter 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 (AmazonMarketplaceConnection connection = new AmazonMarketplaceConnection( "AWS Access Key Id=myAWSAccessKeyId;AWS Secret Key=myAWSSecretKey;MWS Auth Token=myMWSAuthToken;Seller Id=mySellerId;Marketplace=United States;")) { AmazonMarketplaceDataAdapter AmazonMarketplaceDataAdapter1 = new AmazonMarketplaceDataAdapter("SELECT AmazonOrderId, OrderStatus FROM Orders WHERE IsReplacementOrder = True", connection); DataTable table = new DataTable(); AmazonMarketplaceDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "OrderStatus" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "AmazonOrderId"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
