Good.
Server side TextChanged event handling is a bad idea - it means that each keypress by the user has to make a round trip to the server and back, which is slow and wasteful.

So instead, use Javascript TextChanged event handling, and store the changed control information there for final processing server side when the user has completed the page and submits it.

Solution 2

That's highly inefficient and requires a sh*t-ton of needless code. Just save the whole entity and be done with it. If your entities and DAL are properly designed, this shouldn't be an issue.
