Connect to SharePoint Excel Services Data from PowerBuilder via ADO.NET

This article demonstrates using the CData ADO.NET Provider for SharePoint Excel Services 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 SharePoint Excel Services 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:

   URL=https://myorg.sharepoint.com;[email protected];Password=password;File=Book1.xlsx;

   The URL, User, and Password properties, under the Authentication section, must be set to valid credentials for SharePoint Online, SharePoint 2010, or SharePoint 2013. Additionally, the Library property must be set to a valid SharePoint Document Library and the File property must be set to a valid .xlsx file in the indicated Library.

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=Name}" Header="Name" Width="SizeToHeader" />
   		...
   	</DataGrid.Columns>
   </DataGrid>
   

4. Add a reference to the CData ADO.NET Provider for SharePoint Excel Services 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.ExcelServices.ExcelServicesConnection conn 
conn = create System.Data.CData.ExcelServices.ExcelServicesConnection(connectionString)

System.Data.CData.ExcelServices.ExcelServicesCommand comm 
comm = create System.Data.CData.ExcelServices.ExcelServicesCommand(command, conn)

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

System.Data.CData.ExcelServices.ExcelServicesDataAdapter dataAdapter
dataAdapter = create System.Data.CData.ExcelServices.ExcelServicesDataAdapter(comm)
dataAdapter.Fill(table)	
datagrid1.ItemsSource=table.DefaultView

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