Email ADO.NET Provider

The easiest way to integrate powerful Email send and receive capabilities with .NET applications. Send & Receive Email through POP3, IMAP, and SMTP, Verify Addresses, and more!



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

The CData ADO.NET Provider for Email 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 User and Password properties, under the Authentication section, must be set to valid credentials. The Server must be specified to retrieve emails and the SMTPServer must be specified to send emails.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Email data. The EmailDataAdapter 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 (EmailConnection connection = new EmailConnection( "User=username@gmail.com;Password=password;Server=imap.gmail.com;Port=993;SMTP Server=smtp.gmail.com;SMTP Port=465;SSL Mode=EXPLICIT;Protocol=IMAP;Mailbox=Inbox;")) { EmailDataAdapter dataAdapter = new EmailDataAdapter( "SELECT Mailbox, RecentMessagesCount FROM Mailboxes", 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[] { "RecentMessagesCount" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Mailbox"; 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 Email data. The EmailDataAdapter 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 (EmailConnection connection = new EmailConnection( "User=username@gmail.com;Password=password;Server=imap.gmail.com;Port=993;SMTP Server=smtp.gmail.com;SMTP Port=465;SSL Mode=EXPLICIT;Protocol=IMAP;Mailbox=Inbox;")) { EmailDataAdapter EmailDataAdapter1 = new EmailDataAdapter("SELECT Mailbox, RecentMessagesCount FROM Mailboxes", connection); DataTable table = new DataTable(); EmailDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "RecentMessagesCount" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Mailbox"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
