DataBind Office 365 Data to the DevExpress Data Grid

The ADO.NET Provider for Office 365 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.

Office 365 uses the OAuth authentication standard. To authenticate requests, obtain the OAuthClientId, OAuthClientSecret, and OAuthCallbackURL by registering an app with Office 365. See the "Getting Started" chapter of the help documentation for a guide to using OAuth.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Office 365 data. The Office365DataAdapter 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 (Office365Connection connection = new Office365Connection(
"OAuthClientId=MyApplicationId;OAuthClientSecret=MyAppKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;")) {
 Office365DataAdapter dataAdapter = new Office365DataAdapter(
 "SELECT Name, Size FROM Files ORDER BY Size", 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[] { "Size" });
 series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
 series.ArgumentDataMember = "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 Office 365 data. The Office365DataAdapter 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 (Office365Connection connection = new Office365Connection(
"OAuthClientId=MyApplicationId;OAuthClientSecret=MyAppKey;OAuthCallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;"))
{
 Office365DataAdapter Office365DataAdapter1 = new Office365DataAdapter("SELECT Name, Size FROM Files ORDER BY Size", connection);
 DataTable table = new DataTable();
 Office365DataAdapter1.Fill(table);
 DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
 WebChartControl1.Series.Add(series);
 series.DataSource = table;
 series.ValueDataMembers.AddRange(new string[] { "Size" });
 series.ArgumentScaleType = ScaleType.Qualitative;
 series.ArgumentDataMember = "Name";
 series.ValueScaleType = ScaleType.Numerical;
 ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
