ADOAdapter employeesDA =
   (ADOAdapter)thisXDocument.DataAdapters["Employees"];
// Get employee’s ID from the main DOM
string employeeID = 
   thisXDocument.DOM.selectSingleNode("//my:field2").text;
// Change the ADOAdapter’s command to retrieve the record 
// of the Employee's ID entered by the user
employeesDA.Command = 
   "select * from Employees where EmployeeID="+employeeID;
// Get DataObject from the DataObjects collection and 
// call Query to refresh the data object.
DataSourceObject employeesDO =
   (DataSourceObject)thisXDocument.DataObjects["Employees"];
employeesDO.Query();
