Excel ADO.NET Provider

Easily connect .NET applications with real-time data from Excel spreadsheets. Use Excel to manage the data that powers your applications.



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

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 Excel in PowerBuilder.

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

    Excel File='C:/MyExcelWorkbooks/SampleWorkbook.xlsx';

    The ExcelFile, under the Authentication section, must be set to a valid Excel File.

  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 Excel 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.Excel.ExcelConnection conn conn = create System.Data.CData.Excel.ExcelConnection(connectionString) System.Data.CData.Excel.ExcelCommand comm comm = create System.Data.CData.Excel.ExcelCommand(command, conn) System.Data.DataTable table table = create System.Data.DataTable System.Data.CData.Excel.ExcelDataAdapter dataAdapter dataAdapter = create System.Data.CData.Excel.ExcelDataAdapter(comm) dataAdapter.Fill(table) datagrid1.ItemsSource=table.DefaultView

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