DataBind Certinia Data to the DevExpress Data Grid


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

The ADO.NET Provider for Certinia 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.

There are several authentication methods available for connecting to Certinia: login credentials, SSO, and OAuth.

Authenticating with a Login and Token

Set the User and Password to your login credentials. Additionally, set the SecurityToken. By default, the SecurityToken is required, but you can make it optional by allowing a range of trusted IP addresses.

To disable the security token:

  1. Log in to Certinia and enter "Network Access" in the Quick Find box in the setup section.
  2. Add your IP address to the list of trusted IP addresses.

To obtain the security token:

  1. Open the personal information page on certinia.com.
  2. Click the link to reset your security token. The token will be emailed to you.
  3. Specify the security token in the SecurityToken connection property or append it to the Password.

Authenticating with OAuth

If you do not have access to the user name and password or do not want to require them, use the OAuth user consent flow. See the OAuth section in the Help for an authentication guide.

Connecting to Certinia Sandbox Accounts

Set UseSandbox to true (false by default) to use a Certinia sandbox account. Ensure that you specify a sandbox user name in User.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Certinia data. The CertiniaDataAdapter 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 (CertiniaConnection connection = new CertiniaConnection( "User=myUser;Password=myPassword;Security Token=myToken;InitiateOAuth=GETANDREFRESH")) { CertiniaDataAdapter dataAdapter = new CertiniaDataAdapter( "SELECT BillingState, Name FROM Account WHERE Industry = 'Floppy Disks'", 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[] { "Name" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "BillingState"; 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 Certinia data. The CertiniaDataAdapter 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 (CertiniaConnection connection = new CertiniaConnection( "User=myUser;Password=myPassword;Security Token=myToken;InitiateOAuth=GETANDREFRESH")) { CertiniaDataAdapter CertiniaDataAdapter1 = new CertiniaDataAdapter("SELECT BillingState, Name FROM Account WHERE Industry = 'Floppy Disks'", connection); DataTable table = new DataTable(); CertiniaDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Name" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "BillingState"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
