DataBind Respond.io 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.

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

Respondio API Profile Settings

Respond.io uses API key authentication. To obtain an API key:

1. Log in to your Respond.io account.
2. Navigate to Settings in your workspace.
3. Select Developer under the Integrations section.
4. Copy the API key displayed on the page.

After obtaining your API key, set the following connection properties:

• AuthScheme: Set this to APIKey.

Set the following in the ProfileSettings connection property:

• APIKey: Set this to your Respond.io API key.

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Respond.io 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\Respondio.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';")) {
  APIDataAdapter dataAdapter = new APIDataAdapter(
  "SELECT Id, Email FROM Contacts WHERE Identifier = 'id:438180634'", 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[] { "Email" });
  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;                              
}

Web Controls

The code below shows how to populate a DevExpress Web control with Respond.io 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\Respondio.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key';"))
{
  APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT Id, Email FROM Contacts WHERE Identifier = 'id:438180634'", 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[] { "Email" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "Id";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
