DataBind Twitter Data to the DevExpress Data Grid


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

The ADO.NET Provider for Twitter 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.

All tables require authentication. You can connect using your User and Password or OAuth. To authenticate using OAuth, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL or you can register an app to obtain your own.

If you intend to communicate with Twitter only as the currently authenticated user, then you can obtain the OAuthAccessToken and OAuthAccessTokenSecret directly by registering an app.

See the Getting Started chapter in the help documentation for a guide to using OAuth.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Twitter data. The TwitterDataAdapter 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 (TwitterConnection connection = new TwitterConnection( "InitiateOAuth=GETANDREFRESH")) { TwitterDataAdapter dataAdapter = new TwitterDataAdapter( "SELECT From_User_Name, Retweet_Count FROM Tweets", 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[] { "Retweet_Count" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "From_User_Name"; 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 Twitter data. The TwitterDataAdapter 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 (TwitterConnection connection = new TwitterConnection( "InitiateOAuth=GETANDREFRESH")) { TwitterDataAdapter TwitterDataAdapter1 = new TwitterDataAdapter("SELECT From_User_Name, Retweet_Count FROM Tweets", connection); DataTable table = new DataTable(); TwitterDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Retweet_Count" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "From_User_Name"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
