Google Calendars ADO.NET Provider

An easy-to-use database-like interface for .NET applications access to live Google Calendar data (Calendars, Events, Attendees and more).



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

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 Google Calendar in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Google Calendar to perform reads and writes.

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

    You can connect to Google APIs on behalf of individual users or on behalf of a domain. Google uses the OAuth authentication standard. See the "Getting Started" section of the help documentation for a guide.

  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=Summary}" Header="Summary" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Google Calendar 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.GoogleCalendar.GoogleCalendarConnection conn conn = create System.Data.CData.GoogleCalendar.GoogleCalendarConnection(connectionString) System.Data.CData.GoogleCalendar.GoogleCalendarCommand comm comm = create System.Data.CData.GoogleCalendar.GoogleCalendarCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.GoogleCalendar.GoogleCalendarDataAdapter dataAdapter dataAdapter = create System.Data.CData.GoogleCalendar.GoogleCalendarDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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