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 ADO.NET Provider for Google Search 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.
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;
}
