DataBind Bugzilla Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Bugzilla 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.

Bugzilla アカウントには以下の接続プロパティで接続します:

  • URL: Bugzilla 開発者ページの(Home ページ)。
  • ApiKey: Bugzilla 開発者ページのPreferences -> API Keys で生成したAPI Key。

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Bugzilla data. The BugzillaDataAdapter 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 (BugzillaConnection connection = new BugzillaConnection( "Url=http://yourdomain/Bugzilla;APIKey=abc123;")) { BugzillaDataAdapter dataAdapter = new BugzillaDataAdapter( "SELECT Id, Summary FROM Bugs WHERE Creator = 'user@domain.com'", 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[] { "Summary" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Id"; 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 Bugzilla data. The BugzillaDataAdapter 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 (BugzillaConnection connection = new BugzillaConnection( "Url=http://yourdomain/Bugzilla;APIKey=abc123;")) { BugzillaDataAdapter BugzillaDataAdapter1 = new BugzillaDataAdapter("SELECT Id, Summary FROM Bugs WHERE Creator = 'user@domain.com'", connection); DataTable table = new DataTable(); BugzillaDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Summary" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
