DataBind Halo Service Desk 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 HaloServiceDesk Profile on disk (e.g. C:\profiles\HaloServiceDesk.apip). Next, set the ProfileSettings connection property to the connection string for HaloServiceDesk (see below).

HaloServiceDesk API Profile Settings

HaloServiceDesk uses API key authentication. You can find or create API keys in HaloServiceDesk under Administration > Integrations > Halo API.

Set the following connection properties to connect:

• AuthScheme: Set this to APIKey.
• APIKey: Set this to the API key from your HaloServiceDesk account.
• Domain: Set this to the hostname of your HaloServiceDesk instance (e.g. yourcompany.haloservicedesk.com).

Windows Forms Controls

The code below shows how to populate a DevExpress chart with Halo Service Desk 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\HaloServiceDesk.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key;Domain=yourcompany.haloservicedesk.com';")) {
  APIDataAdapter dataAdapter = new APIDataAdapter(
  "SELECT Id, InventoryNumber FROM Assets WHERE ClientId = '1'", 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[] { "InventoryNumber" });
  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 Halo Service Desk 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\HaloServiceDesk.apip;AuthScheme=APIKey;ProfileSettings='APIKey=your_api_key;Domain=yourcompany.haloservicedesk.com';"))
{
  APIDataAdapter APIDataAdapter1 = new APIDataAdapter("SELECT Id, InventoryNumber FROM Assets WHERE ClientId = '1'", 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[] { "InventoryNumber" });
  series.ArgumentScaleType = ScaleType.Qualitative;
  series.ArgumentDataMember = "Id";
  series.ValueScaleType = ScaleType.Numerical;
  ((DevExpress.XtraCharts.SideBySideBarSeriesView)series.View).ColorEach = true;
}
