Validates and updates the result schema available on the client after confirming the execution of associated queries (the result schema can be accessed using the SqlDataSource.Result property). This command does not affect the actual database schema on the server.

public void RebuildResultSchema( Predicate<IEnumerable<SqlQuery>> confirmExecution )
Public Sub RebuildResultSchema( confirmExecution As Predicate(Of IEnumerable(Of SqlQuery)) )
A method that defines a set of criteria to determine whether or not the specified SqlQuery strings have been executed.
If errors occur during data connection, a DatabaseConnectionException is thrown.
All queries are validated one by one. When validation errors occur, they are collected and returned by throwing a AggregateException. Use its InnerExceptions property to access a collection of QueryExecutionException objects (use their InnerException property to access an actual ValidationException).
If the validation succeeds, all queries are executed one by one. If any errors occur during the execution of each query, these errors are collected and returned by throwing a AggregateException. Use its InnerExceptions property to access a collection of QueryExecutionException objects (use their InnerException property to access an actual DevExpress.DataAccess.Native.Sql.SqlExecutionException).
When using a SqlDataSource to bind an XtraReport to data, call the RebuildResultSchema method to make the data source structure displayed in the Field List of an End-User Report Designer. For a code sample, see Bind a Report to a Microsoft SQL Server Database (Runtime Sample).
