DataBind WordPress Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for WordPress 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.

データに接続するには、Url を設定して認証を提供します。URL はワードプレスサイトに設定しなければなりません。そうしないと、サーバーが見つからない旨を示すエラーがスローされます。 例えば、あなたのサイトが'http://localhost/wp/wordpress' でホストされている場合、URL は'http://localhost' ではなく、'http://localhost/wp/wordpress' となるべきです。

Windows Forms Controls

The code below shows how to populate a DevExpress chart with WordPress data. The WordPressDataAdapter 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 (WordPressConnection connection = new WordPressConnection( "Url=http://www.yourwordpresshost.com;")) { WordPressDataAdapter dataAdapter = new WordPressDataAdapter( "SELECT Id, Name FROM Categories", 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 = "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 WordPress data. The WordPressDataAdapter 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 (WordPressConnection connection = new WordPressConnection( "Url=http://www.yourwordpresshost.com;")) { WordPressDataAdapter WordPressDataAdapter1 = new WordPressDataAdapter("SELECT Id, Name FROM Categories", connection); DataTable table = new DataTable(); WordPressDataAdapter1.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 = "Id"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
