DataBind Smartsheet Data to the DevExpress Data Grid

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

The CData ADO.NET Provider for Smartsheet 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.

Smartsheet uses the OAuth authentication standard. To authenticate using OAuth, you will need to register an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties.

However, for testing purposes you can instead use the Personal Access Token you get when you create an application; set this to the OAuthAccessToken connection property.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Smartsheet data. The SmartsheetDataAdapter 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 (SmartsheetConnection connection = new SmartsheetConnection( "OAuthClientId=MyOauthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH")) { SmartsheetDataAdapter dataAdapter = new SmartsheetDataAdapter( "SELECT TaskName, Progress FROM Sheet_Event_Plan_Budget", 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[] { "Progress" }); series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative; series.ArgumentDataMember = "TaskName"; 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 Smartsheet data. The SmartsheetDataAdapter 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 (SmartsheetConnection connection = new SmartsheetConnection( "OAuthClientId=MyOauthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH")) { SmartsheetDataAdapter SmartsheetDataAdapter1 = new SmartsheetDataAdapter("SELECT TaskName, Progress FROM Sheet_Event_Plan_Budget", connection); DataTable table = new DataTable(); SmartsheetDataAdapter1.Fill(table); DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar); WebChartControl1.Series.Add(series); series.DataSource = table; series.ValueDataMembers.AddRange(new string[] { "Progress" }); series.ArgumentScaleType = ScaleType.Qualitative; series.ArgumentDataMember = "TaskName"; series.ValueScaleType = ScaleType.Numerical; ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true; }
