DataBind Salesforce Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Salesforce 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.

Salesforce への接続にはLogin、OAuth、SSO の種類があります。Login 方式では、Username、Password、Security Token を使って接続します。

Username、Password を使用しない/できない場合、OAuth 認証を使用することができます。

SSO (シングルサインオン) は、SSOProperties、SSOLoginUrl、TokenUrl プロパティを設定することでIdentity プロバイダ経由で利用できます。詳細はヘルプドキュメントの「はじめに」を参照してください。

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Salesforce data. The SalesforceDataAdapter 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 (SalesforceConnection connection = new SalesforceConnection( "User=username;Password=password;SecurityToken=Your_Security_Token;")) { SalesforceDataAdapter dataAdapter = new SalesforceDataAdapter( "SELECT Contact.Name, SUM(Account.AnnualRevenue) FROM Contact, Account GROUP BY Contact.Name", 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[] { "AnnualRevenue" }); 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 Salesforce data. The SalesforceDataAdapter 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 (SalesforceConnection connection = new SalesforceConnection( "User=username;Password=password;SecurityToken=Your_Security_Token;")) { SalesforceDataAdapter SalesforceDataAdapter1 = new SalesforceDataAdapter("SELECT Contact.Name, SUM(Account.AnnualRevenue) FROM Contact, Account GROUP BY Contact.Name", connection); DataTable table = new DataTable(); SalesforceDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "AnnualRevenue" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Industry"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
