Connect to Todoist Data from PowerBuilder


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

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

    Profile=C:\profiles\Todoist.apip;Authscheme=OAuth;OAuthClientId=your_client_id;OAuthClientSecret=your_client_secret;CallbackUrl=your_callback_url;InitiateOAuth=GETANDREFRESH

    Start by setting the Profile connection property to the location of the Todoist Profile on disk (e.g. C:\profiles\Todoist.apip). Next, set the ProfileSettings connection property to the connection string for Todoist (see below).

    Todoist API Profile Settings

    To authenticate to Todoist, and connect to your own data or to allow other users to connect to their data, you can use the OAuth standard.

    First, you will need to register an OAuth application with Todoist. To do so, go to App Management Console, create a new application and configure a valid OAuth redirect URL. Your Oauth application will be assigned a client id and a client secret.

    After setting the following connection properties, you are ready to connect:

    • AuthScheme: Set this to OAuth.
    • InitiateOAuth: Set this to GETANDREFRESH. You can use InitiateOAuth to manage the process to obtain the OAuthAccessToken.
    • OAuthClientId: Set this to the client_id that is specified in you app settings.
    • OAuthClientSecret: Set this to the client_secret that is specified in you app settings.
    • CallbackURL: Set this to the Redirect URI that is specified in your app settings

  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 Todoist 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.API.APIConnection conn conn = create System.Data.CData.API.APIConnection(connectionString) System.Data.CData.API.APICommand comm comm = create System.Data.CData.API.APICommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.API.APIDataAdapter dataAdapter dataAdapter = create System.Data.CData.API.APIDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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