Connect to Zoho Projects Data from PowerBuilder via ADO.NET

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

   InitiateOAuth=GETANDREFRESH;

   The connector uses OAuth to authenticate with Zoho Projects. CData Software has already registered an OAuth application with Zoho Project which is embedded and used to authenticate.

   If you use the embedded credentials, set the InitiateOAuth connection property to "GETANDREFRESH".

   If you would prefer to use your own custom OAuth app, see the Help documentation.

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 Zoho Projects 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.ZohoProjects.ZohoProjectsConnection conn 
conn = create System.Data.CData.ZohoProjects.ZohoProjectsConnection(connectionString)

System.Data.CData.ZohoProjects.ZohoProjectsCommand comm 
comm = create System.Data.CData.ZohoProjects.ZohoProjectsCommand(command, conn)

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

System.Data.CData.ZohoProjects.ZohoProjectsDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ZohoProjects.ZohoProjectsDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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