User types text into a TextBox, e.g. for searching in a table. With the TextChanged event, you can send a query to the database every time the user hits a key.


You don’t know if the user has finished writing. If this is a huge table in your database, the select query can last a few seconds, and this is even not useful, when the search text hasn’t been written completely by the user.


Have a look at this thread on StackOverflow. They use a timer to achieve a good workaround for this problem.
