DataBind RSS Feeds to the DevExpress Data Grid


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

The ADO.NET Provider for RSS 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.

You can connect to RSS and Atom feeds, as well as feeds with custom extensions. To connect to a feed, set the URL property. You can also access secure feeds. A variety of authentication mechanisms are supported. See the help documentation for details.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with RSS feeds. The RSSDataAdapter 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 (RSSConnection connection = new RSSConnection( "URI=http://broadcastCorp/rss/;")) { RSSDataAdapter dataAdapter = new RSSDataAdapter( "SELECT Pubdate, Author FROM RSSFeed", 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[] { "Pubdate" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Author"; 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 RSS feeds. The RSSDataAdapter 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 (RSSConnection connection = new RSSConnection( "URI=http://broadcastCorp/rss/;")) { RSSDataAdapter RSSDataAdapter1 = new RSSDataAdapter("SELECT Pubdate, Author FROM RSSFeed", connection); DataTable table = new DataTable(); RSSDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Pubdate" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Author"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
