DataBind Azure Table Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Azure Table 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.

Specify your AccessKey and your Account to connect. Set the Account property to the Storage Account Name and set AccessKey to one of the Access Keys. Either the Primary or Secondary Access Keys can be used. To obtain these values, navigate to the Storage Accounts blade in the Azure portal. You can obtain the access key by selecting your account and clicking Access Keys in the Settings section.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Azure Table data. The AzureTablesDataAdapter 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 (AzureTablesConnection connection = new AzureTablesConnection( "AccessKey=myAccessKey;Account=myAccountName;")) { AzureTablesDataAdapter dataAdapter = new AzureTablesDataAdapter( "SELECT Name, Price FROM NorthwindProducts", 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[] { "Price" }); 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 Azure Table data. The AzureTablesDataAdapter 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 (AzureTablesConnection connection = new AzureTablesConnection( "AccessKey=myAccessKey;Account=myAccountName;")) { AzureTablesDataAdapter AzureTablesDataAdapter1 = new AzureTablesDataAdapter("SELECT Name, Price FROM NorthwindProducts", connection); DataTable table = new DataTable(); AzureTablesDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Price" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
