Connect to Microsoft Planner Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for Microsoft Planner 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 Microsoft Planner 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:

   OAuthClientId=MyApplicationId;OAuthClientSecret=MySecretKey;CallbackURL=http://localhost:33333;InitiateOAuth=GETANDREFRESH;

   You can connect without setting any connection properties for your user credentials. Below are the minimum connection properties required to connect.

   • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to avoid repeating the OAuth exchange and manually setting the OAuthAccessToken.
   • Tenant (optional): Set this if you wish to authenticate to a different tenant than your default. This is required to work with an organization not on your default Tenant.

   When you connect the Driver opens the MS Planner OAuth endpoint in your default browser. Log in and grant permissions to the Driver. The Driver then completes the OAuth process.

   1. Extracts the access token from the callback URL and authenticates requests.
   2. Obtains a new access token when the old one expires.
   3. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
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=TaskId}" Header="TaskId" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for Microsoft Planner 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.MicrosoftPlanner.MicrosoftPlannerConnection conn 
conn = create System.Data.CData.MicrosoftPlanner.MicrosoftPlannerConnection(connectionString)

System.Data.CData.MicrosoftPlanner.MicrosoftPlannerCommand comm 
comm = create System.Data.CData.MicrosoftPlanner.MicrosoftPlannerCommand(command, conn)

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

System.Data.CData.MicrosoftPlanner.MicrosoftPlannerDataAdapter dataAdapter
dataAdapter = create System.Data.CData.MicrosoftPlanner.MicrosoftPlannerDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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