Your WPF application needs to display a list of employees and their performance ratings from a database. Explain how you would implement data binding with sorting and filtering capabilities.

  • Data binding with CollectionViewSource and ICollectionView interface
  • Data binding with Entity Framework Core
  • Data binding with DataGrid control
  • Data binding with DataSet
To implement data binding with sorting and filtering capabilities in a WPF application, you can use CollectionViewSource along with the ICollectionView interface. CollectionViewSource provides a wrapper around your data source, while ICollectionView offers sorting and filtering functionalities. You can bind your employee data to a CollectionViewSource and then apply sorting and filtering criteria through the ICollectionView interface, allowing users to interactively sort and filter the employee list in the UI. This approach provides a flexible and efficient way to handle sorting and filtering requirements while maintaining a clean separation between UI and data logic. The other options may not offer built-in support for dynamic sorting and filtering or may require more manual coding effort.

The CommandType property can be set to ___________ when executing a text-based SQL query.

  • StoredProcedure
  • TableDirect
  • Text
  • Function
The correct option is Text. When executing a text-based SQL query using ADO.NET, you can set the CommandType property of the command object to Text. This indicates that the command text contains a SQL query statement to be executed directly against the database. Setting the CommandType to Text is appropriate for executing dynamic SQL queries or stored procedures that return rows.

Which LINQ operator is used to filter elements in a sequence based on a specified condition?

  • Filter
  • OrderBy
  • Select
  • Where
The Where operator is used to filter elements in a sequence based on a specified condition. It allows you to specify a predicate function that determines which elements to include in the result sequence.

The ExecuteScalar method is suitable for retrieving a ___________ value from a SELECT statement.

  • Single
  • Multiple
  • Aggregate
  • Composite
The correct option is Option 1: Single. The ExecuteScalar method in ADO.NET is used to execute a SQL query that returns a single value, such as a count, sum, average, or any other aggregate or scalar value, typically from a SELECT statement with a WHERE clause.
