Connect to Xero Data from PowerBuilder


This article demonstrates how to access Xero data from Appeon PowerBuilder using the CData ADO.NET Provider for Xero.

This article demonstrates using the CData ADO.NET Provider for Xero 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 Xero to perform reads and writes.

  1. In a new WPF Window Application solution, add all the Visual Controls needed for the connection properties.

    To connect, set the Schema connection property in addition to any authentication values. Xero offers authentication for private applications, public applications, and partner applications. You will need to set the XeroAppAuthentication property to PUBLIC, PRIVATE, or PARTNER, depending on the type of application configured. To connect from a private application, you will additionally need to set the OAuthAccessToken, OAuthClientId, OAuthClientSecret, CertificateStoreType, CertificateStore, and CertificateStorePassword.

    To connect from a public or partner application, you can use the embedded OAuthClientId, OAuthClientSecret, and CallbackURL, or you can register an app to obtain your own OAuth values.

    See the "Getting Started" chapter of the help documentation for a guide to authenticating to Xero.

  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=Name}" Header="Name" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Xero 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.Xero.XeroConnection conn conn = create System.Data.CData.Xero.XeroConnection(connectionString) System.Data.CData.Xero.XeroCommand comm comm = create System.Data.CData.Xero.XeroCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Xero.XeroDataAdapter dataAdapter dataAdapter = create System.Data.CData.Xero.XeroDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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