Bing Search ADO.NET Provider
Easy-to-use Bing search client enables .NET-based applications to easily search Microsoft Bing and filter search results.
Use the CData ADO.NET Provider for Bing Search with the DevExpress Windows Forms and Web controls to provide Bing Search results to a chart.
The CData ADO.NET Provider for Bing 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 connect to Bing, set the ApiKey connection property. To obtain the API key, sign into Microsoft Cognitive Services and register for the Bing Search APIs.
Two API keys are then generated; select either one.
When querying tables, the SearchTerms parameter must be supplied in the WHERE clause.
Windows Forms Controls
The code below shows how to populate a DevExpress chart with Bing Search results. The BingDataAdapter 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 (BingConnection connection = new BingConnection(
"APIKey=MyAPIKey;")) {
BingDataAdapter dataAdapter = new BingDataAdapter(
"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 Bing Search results. The BingDataAdapter 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 (BingConnection connection = new BingConnection(
"APIKey=MyAPIKey;"))
{
BingDataAdapter BingDataAdapter1 = new BingDataAdapter("SELECT Title, ViewCount FROM VideoSearch WHERE SearchTerms = 'WayneTech'", connection);
DataTable table = new DataTable();
BingDataAdapter1.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;
}
