The CData ADO.NET Provider for Freshdesk 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.
FreshDesk makes use of basic authentication. To connect to data, set the following connection properties:
- Domain: Set this to the domain associated with your FreshDesk account. For example, in your URL: https://my_domain.freshdesk.com.
- APIKey: Set this to the API key associated with your FreshDesk account. To retrieve your API key, Log into your support Portal -> Click on profile picture in the top right corner -> profile settings page. The API key will be available below the change password section to the right.
The code below shows how to populate a DevExpress chart with Freshdesk data. The FreshDeskDataAdapter 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 (FreshDeskConnection connection = new FreshDeskConnection(
"Domain=MyDomain;APIKey=myAPIKey;")) {
FreshDeskDataAdapter dataAdapter = new FreshDeskDataAdapter(
"SELECT Id, Name FROM Tickets WHERE Status = '2'", 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 code below shows how to populate a DevExpress Web control with Freshdesk data. The FreshDeskDataAdapter 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 (FreshDeskConnection connection = new FreshDeskConnection(
"Domain=MyDomain;APIKey=myAPIKey;"))
{
FreshDeskDataAdapter FreshDeskDataAdapter1 = new FreshDeskDataAdapter("SELECT Id, Name FROM Tickets WHERE Status = '2'", connection);
DataTable table = new DataTable();
FreshDeskDataAdapter1.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;
}
