DataBind Pushbullet Data to the DevExpress Data Grid

The CData API Driver for ADO.NET 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.

Using API Key Authentication

Pushbullet uses token-based authentication (Access Token). To obtain an Access Token:

1. Log in to your Pushbullet account at https://www.pushbullet.com
2. Navigate to Settings > Account
3. Click "Create Access Token"
4. Copy the generated token

After obtaining your Access Token, set the following connection properties:

• AuthScheme: Set this to APIKey.

• APIKey: Set this to your Pushbullet Access Token.

Example Connection String

Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;

Connecting to Pushbullet

Once the authentication is configured, you can connect to Pushbullet and query data from any of the available tables such as Users, Pushes, Devices, Chats, Subscriptions, and Channels.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Pushbullet data. The APIDataAdapter 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 (APIConnection connection = new APIConnection(
"Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;")) {
  APIDataAdapter dataAdapter = new APIDataAdapter(
  "SELECT ,  FROM Users WHERE  = ''", 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[] { "" });
  series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
  series.ArgumentDataMember = "";
  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 Pushbullet data. The APIDataAdapter 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 (APIConnection connection = new APIConnection(
"Profile=C:\profiles\Pushbullet.apip;ProfileSettings='APIKey=your_access_token;';AuthScheme=APIKey;"))
{
  APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT ,  FROM Users WHERE  = ''", connection);
  DataTable table = new DataTable();
  APIDataAdapter1.Fill(table);
  DevExpress.XtraCharts.Series series = new Series("Series1", ViewType.Bar);
  WebChartControl1.Series.Add(series);
  series.DataSource = table;
  series.ValueDataMembers.AddRange(new string[] { "" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
