I don't know what you mean by "long", but our body of code that does this
is:
1) The HTML file at 332 lines
2) The processing file at 155 lines
3) About 200 lines of code in our main library
Each table also has a separate file that defines all of its parameters, but
these are computer-generated so we don't really think about length.
So anyway, your basic approach seems sound, but I'll warn you of one thing
we ran into. We allow two states, a browse of search results, and a
one-row detail view. This complicates the code a bit.
We've done away with the switch-to-edit-mode, it is not really necessary.
When a user views a row, they can save or not save, they are always in edit
mode.
We've done away with fancy client-side javascript control of the page and do
lots of round trips to the server. Here is one reason. If the user is
editing a row, then the column "state" might be a drop-down list of US
States. But if the user is in "search" mode, then you want free-form entry
there.
Hope this helps, we have done a complete version of this so I'd be happy to
answer any questions I can.
