DataBind Wasabi Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Wasabi 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 authorize Wasabi requests, provide the credentials for an administrator account or for an IAM user with custom permissions. Set AccessKey to the access key Id. Set SecretKey to the secret access key.

Note: You can connect as the AWS account administrator, but it is recommended to use IAM user credentials to access AWS services.

For information on obtaining the credentials and other authentication methods, refer to the Getting Started section of the Help documentation.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Wasabi data. The WasabiDataAdapter 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 (WasabiConnection connection = new WasabiConnection( "AccessKey=a123;SecretKey=s123;")) { WasabiDataAdapter dataAdapter = new WasabiDataAdapter( "SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'", 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[] { "OwnerId" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Name"; 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 Wasabi data. The WasabiDataAdapter 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 (WasabiConnection connection = new WasabiConnection( "AccessKey=a123;SecretKey=s123;")) { WasabiDataAdapter WasabiDataAdapter1 = new WasabiDataAdapter("SELECT Name, OwnerId FROM Buckets WHERE Name = 'TestBucket'", connection); DataTable table = new DataTable(); WasabiDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "OwnerId" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
