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

The CData ADO.NET providers are easy-to-use, standards-based controls that can be used from any platform or development technology that supports Microsoft .NET, including PowerBuilder. This article shows how to use the CData ADO.NET Provider for eBay in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for eBay 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:

    AppId=MyAppId;CertId=MyCertId;DevId=MyDevId;SiteId=MySiteId;RuName=MyRuName;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH

    If you will be accessing your own account, you can generate an OAuthAccessToken from your developer account dashboard. You can also allow other users to securely access their own accounts.

    Both of these methods require you to create an application key set to obtain values for the following connection properties: AppId, CertId, DevId, and SiteId.

    The user consent flow additionally requires the RuName and CallbackURL.

    See the "Getting Started" chapter in the help documentation for a guide to using OAuth.

  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=Title}" Header="Title" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for eBay 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.Ebay.EbayConnection conn conn = create System.Data.CData.Ebay.EbayConnection(connectionString) System.Data.CData.Ebay.EbayCommand comm comm = create System.Data.CData.Ebay.EbayCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Ebay.EbayDataAdapter dataAdapter dataAdapter = create System.Data.CData.Ebay.EbayDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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