DataBind Amazon DynamoDB Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Amazon DynamoDB 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.

The connection to Amazon DynamoDB is made using your AccessKey, SecretKey, and optionally your Domain and Region. Your AccessKey and SecretKey can be obtained on the security credentials page for your Amazon Web Services account. Your Region will be displayed in the upper left-hand corner when you are logged into DynamoDB.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Amazon DynamoDB data. The AmazonDynamoDBDataAdapter 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 (AmazonDynamoDBConnection connection = new AmazonDynamoDBConnection( "Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;")) { AmazonDynamoDBDataAdapter dataAdapter = new AmazonDynamoDBDataAdapter( "SELECT Industry, Revenue FROM Lead", 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[] { "Revenue" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Industry"; 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 DynamoDB data. The AmazonDynamoDBDataAdapter 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 (AmazonDynamoDBConnection connection = new AmazonDynamoDBConnection( "Access Key=xxx;Secret Key=xxx;Domain=amazonaws.com;Region=OREGON;")) { AmazonDynamoDBDataAdapter AmazonDynamoDBDataAdapter1 = new AmazonDynamoDBDataAdapter("SELECT Industry, Revenue FROM Lead", connection); DataTable table = new DataTable(); AmazonDynamoDBDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Revenue" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Industry"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
