TaxJar ADO.NET Provider

Rapidly create and deploy powerful .NET applications that integrate with TaxJar.



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

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 TaxJar in PowerBuilder.

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

    APIKey=3bb04218ef8t80efdf1739abf7257144;

    To authenticate to the TaxJar API, you will need to first obtain the API Key from the TaxJar UI.

    NOTE: the API is available only for Professional and Premium TaxJar plans.

    If you already have a Professional or Premium plan you can find the API Key by logging in the TaxJar UI and navigating to Account -> TaxJar API. After obtaining the API Key, you can set it in the APIKey connection property.

    Additional Notes

    • By default, the CData connector will retrieve data of the last 3 months in cases where the entity support date range filtering. You can set StartDate to specify the minimum creation date of the data retrieved.
    • If the API Key has been created for a sandbox API account please set UseSandbox to true, but not all endpoints will work as expected. For more information, refer to the TaxJar developer 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=TransactionID}" Header="TransactionID" Width="SizeToHeader" /> ... </DataGrid.Columns> </DataGrid>
  4. Add a reference to the CData ADO.NET Provider for TaxJar 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.TaxJar.TaxJarConnection conn conn = create System.Data.CData.TaxJar.TaxJarConnection(connectionString) System.Data.CData.TaxJar.TaxJarCommand comm comm = create System.Data.CData.TaxJar.TaxJarCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.TaxJar.TaxJarDataAdapter dataAdapter dataAdapter = create System.Data.CData.TaxJar.TaxJarDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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