DataBind Google Drive Data to the DevExpress Data Grid


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

The ADO.NET Provider for Google Drive 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.

You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Google Drive data. The GoogleDriveDataAdapter 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 (GoogleDriveConnection connection = new GoogleDriveConnection( "InitiateOAuth=GETANDREFRESH")) { GoogleDriveDataAdapter dataAdapter = new GoogleDriveDataAdapter( "SELECT Name, Size FROM Files", 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 Google Drive data. The GoogleDriveDataAdapter 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 (GoogleDriveConnection connection = new GoogleDriveConnection( "InitiateOAuth=GETANDREFRESH")) { GoogleDriveDataAdapter GoogleDriveDataAdapter1 = new GoogleDriveDataAdapter("SELECT Name, Size FROM Files", connection); DataTable table = new DataTable(); GoogleDriveDataAdapter1.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; }
