DataBind LinkedIn Data to the DevExpress Data Grid


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

The ADO.NET Provider for LinkedIn 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.

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; }
