Plaid ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with Plaid account data including Assets, Investments, Liabilities, Transactions, and more!



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

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 Plaid in PowerBuilder.

This article shows how to create a basic PowerBuilder application that uses the CData ADO.NET Provider for Plaid 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:

    AccountId=123456789;InitiateOAuth=GETANDREFRESH

    You can connect to Plaid using the embedded OAuth connectivity. When you connect, the Plaid OAuth endpoint opens in your browser. Log in and grant permissions to complete the OAuth process. See the OAuth section in the online Help documentation for more information on other OAuth authentication flows.

    Optionally set the Account Id property to return data related to a specific Account.

  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=AccountId}" Header="AccountId" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for Plaid 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.Plaid.PlaidConnection conn conn = create System.Data.CData.Plaid.PlaidConnection(connectionString) System.Data.CData.Plaid.PlaidCommand comm comm = create System.Data.CData.Plaid.PlaidCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Plaid.PlaidDataAdapter dataAdapter dataAdapter = create System.Data.CData.Plaid.PlaidDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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