Connect to Freshdesk Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Freshdesk in PowerBuilder, showcasing the ease of use and compatibility of these standards-based controls across various platforms and development technologies that support Microsoft .NET, including Appeon PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Freshdesk to perform reads and writes.

1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties. Below is a typical connection string:

   Domain=MyDomain;APIKey=myAPIKey;

   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.
2. Add the DataGrid control from the .NET controls.
3. Configure the columns of the DataGrid control. Below are several columns from the Account table:

   <DataGrid AutoGenerateColumns="False" Margin="13,249,12,14" Name="datagrid1" TabIndex="70" ItemsSource="{Binding}">
   <DataGrid.Columns>
    <DataGridTextColumn x:Name="idColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" />
    <DataGridTextColumn x:Name="nameColumn" Binding="{Binding Path=Id}" Header="Id" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Freshdesk assembly.

Connect the DataGrid

Once the visual elements have been configured, you can use standard ADO.NET objects like Connection, Command, and DataAdapter to populate a DataTable with the results of an SQL query:

System.Data.CData.FreshDesk.FreshDeskConnection conn 
conn = create System.Data.CData.FreshDesk.FreshDeskConnection(connectionString)

System.Data.CData.FreshDesk.FreshDeskCommand comm 
comm = create System.Data.CData.FreshDesk.FreshDeskCommand(command, conn)

System.Data.DataTable table
table = create System.Data.DataTable

System.Data.CData.FreshDesk.FreshDeskDataAdapter dataAdapter
dataAdapter = create System.Data.CData.FreshDesk.FreshDeskDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

The code above can be used to bind data from the specified query to the DataGrid.
