Use the CData API Driver for ADO.NET with the DevExpress Windows Forms and Web controls to provide Canny data to a chart.

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.

Start by setting the Profile connection property to the location of the Canny Profile on disk (e.g. C:\profiles\Canny.apip). Next, set the ProfileSettings connection property to the connection string for Canny (see below).

Canny API Profile Settings

Canny uses a secret API key to control access to the API. The API key is sent as a JSON body parameter named 'apiKey' in every HTTP POST request to the Canny API endpoints.

To authenticate with the Canny API, you need your company-level secret API key. You can find this key in your Canny account under Settings > API.

After setting the following connection properties, you are ready to connect:

  • AuthScheme: Set this to APIKey.
  • APIKey: Set this to your Canny company-level secret API key from the Settings > API page in your Canny dashboard.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Canny 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\Canny.apip;ProfileSettings='APIKey=your-canny-api-key';")) {
  APIDataAdapter dataAdapter = new APIDataAdapter(
  "SELECT Id, Name FROM Boards WHERE IsPrivate = 'false'", 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[] { "Name" });
  series.ArgumentScaleType = DevExpress.XtraCharts.ScaleType.Qualitative;
  series.ArgumentDataMember = "Id";
  series.ValueScaleType = DevExpress.XtraCharts.ScaleType.Numerical;
  chartControl1.Legend.Visibility = DevExpress.Utils.DefaultBoolean.False;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;                              
}
The complete code example and the resulting chart.

Web Controls

The code below shows how to populate a DevExpress Web control with Canny 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\Canny.apip;ProfileSettings='APIKey=your-canny-api-key';"))
{
  APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT Id, Name FROM Boards WHERE IsPrivate = 'false'", 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[] { "Name" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "Id";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
An ASP.NET application created with the ADO.NET Provider and the DevExpress Web Forms control. (Salesforce is shown.)
