DataBind Google Search Results to the DevExpress Data Grid

Use the CData ADO.NET Provider for Google Search with the DevExpress Windows Forms and Web controls to provide Google Search results to a chart.

The CData ADO.NET Provider for Google Search 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.

To search with a Google custom search engine, you need to set the CustomSearchId and ApiKey connection properties.

To obtain the CustomSearchId property, sign into Google Custom Search Engine and create a new search engine.

To obtain the ApiKey property, you must enable the Custom Search API in the Google API Console.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Google Search results. The GoogleSearchDataAdapter 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 (GoogleSearchConnection connection = new GoogleSearchConnection( "CustomSearchId=def456;ApiKey=abc123;")) { GoogleSearchDataAdapter dataAdapter = new GoogleSearchDataAdapter( "SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'", 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[] { "ViewCount" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "Title"; 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 Google Search results. The GoogleSearchDataAdapter 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 (GoogleSearchConnection connection = new GoogleSearchConnection( "CustomSearchId=def456;ApiKey=abc123;")) { GoogleSearchDataAdapter GoogleSearchDataAdapter1 = new GoogleSearchDataAdapter("SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'", connection); DataTable table = new DataTable(); GoogleSearchDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "ViewCount" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "Title"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
