Connect to Greenhouse Data from PowerBuilder


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

This article demonstrates using the CData ADO.NET Provider for Greenhouse 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 Greenhouse to retrieve data.

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

    APIKey=YourAPIKey;

    You need an API key to connect to Greenhouse. To create an API key, follow the steps below:

    1. Click the Configure icon in the navigation bar and locate Dev Center on the left.
    2. Select API Credential Management.
    3. Click Create New API Key.
      • Set "API Type" to Harvest.
      • Set "Partner" to custom.
      • Optionally, provide a description.
    4. Proceed to Manage permissions and select the appropriate permissions based on the resources you want to access through the driver.
    5. Copy the created key and set APIKey to that value.

  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 Greenhouse 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.Greenhouse.GreenhouseConnection conn conn = create System.Data.CData.Greenhouse.GreenhouseConnection(connectionString) System.Data.CData.Greenhouse.GreenhouseCommand comm comm = create System.Data.CData.Greenhouse.GreenhouseCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Greenhouse.GreenhouseDataAdapter dataAdapter dataAdapter = create System.Data.CData.Greenhouse.GreenhouseDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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