Connect to DocuSign Data from PowerBuilder


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

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

    OAuthClientId=MyClientId; OAuthClientSecret=MyClientSecret; CallbackURL=http://localhost:33333; InitiateOAuth=GETANDREFRESH

    To connect to DocuSign, set the following connection properties:

    • UseSandbox: indicates whether current user account is sandbox or not (FALSE by default)
    • AccountId (optional): set it in the connection string if you have access to multiple Account Ids

    Authenticating to DocuSign

    DocuSign uses the OAuth authentication standard. To authenticate using OAuth, you will need to create an app to obtain the OAuthClientId, OAuthClientSecret, and CallbackURL connection properties. See the Help documentation more information.

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

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