LinkedIn ADO.NET Provider
A straightforward interface to connect any .NET application with LinkedIn integration capabilities including People, Profiles, Companies, Groups, Jobs, and more!
Use the CData ADO.NET Provider for LinkedIn with the DevExpress Windows Forms and Web controls to provide LinkedIn data to a chart.
The CData ADO.NET Provider for LinkedIn 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.
LinkedIn uses the OAuth 2 authentication standard. You will need to obtain the OAuthClientId and OAuthClientSecret by registering an app with LinkedIn. For more information refer to our authentication guide.Windows Forms Controls
The code below shows how to populate a DevExpress chart with LinkedIn data. The LinkedInDataAdapter 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 (LinkedInConnection connection = new LinkedInConnection(
"OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXXInitiateOAuth=GETANDREFRESH")) {
LinkedInDataAdapter dataAdapter = new LinkedInDataAdapter(
"SELECT VisibilityCode, Comment FROM CompanyStatusUpdates", 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[] { "Comment" });
series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
series.ArgumentDataMember = "VisibilityCode";
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 LinkedIn data. The LinkedInDataAdapter 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 (LinkedInConnection connection = new LinkedInConnection(
"OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:portNumber;CompanyId=XXXXXXXInitiateOAuth=GETANDREFRESH"))
{
LinkedInDataAdapter LinkedInDataAdapter1 = new LinkedInDataAdapter("SELECT VisibilityCode, Comment FROM CompanyStatusUpdates", connection);
DataTable table = new DataTable();
LinkedInDataAdapter1.Fill(table);
DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
WebChartControl1.Series.Add(series);
series.DataSource = table;
series.ValueDataMembers.AddRange(new string[] { "Comment" });
series.ArgumentScaleType = ScaleType.Qualitative;
series.ArgumentDataMember = "VisibilityCode";
series.ValueScaleType = ScaleType.Numerical;
((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
