The CData ADO.NET Provider for Box 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.
Box は、認証にOAuth スタンダードを使用します。Box への認証には、登録アプリのOAuthClientId、OAuthClientSecret、CallbackURL を入力します。詳細はヘルプドキュメントの「はじめに」を参照してください。
The code below shows how to populate a DevExpress chart with Box data. The BoxDataAdapter 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 (BoxConnection connection = new BoxConnection(
"OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;")) {
BoxDataAdapter dataAdapter = new BoxDataAdapter(
"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;
}
The code below shows how to populate a DevExpress Web control with Box data. The BoxDataAdapter 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 (BoxConnection connection = new BoxConnection(
"OAuthClientId=MyOAuthClientId;OAuthClientSecret=MyOAuthClientSecret;CallbackURL=http://localhost:33333;"))
{
BoxDataAdapter BoxDataAdapter1 = new BoxDataAdapter("SELECT Name, Size FROM Files", connection);
DataTable table = new DataTable();
BoxDataAdapter1.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;
}
