But it often cannot, or it is too difficult to make it do so, so resorting to SQL is the way to go.
This cost is much more severe if we unnecessarily create many server roundtrips for a task that could be done in a single roundtrip, namely by using a SQL bulk .
If doing everything in a single statement isn't possible due to the limitations of SQL, we can still save roundtrips by grouping statements in a block, either by using an anonymous block in databases that support them: (You can easily send these anonymous blocks over JDBC, as well!
Protected Sub Page_Load(By Val sender As Object, By Val e As System. Load Dim i Col As Integer, c As Integer = 0, i Chx As Integer 'If In Str(Http Context.

I believe that databinding on every postback is the cause but that's not something that I can change right now, same goes with the autogeneratedcolumns setting. I'm not sure if I know what you mean about 2 way binding. If you meanam I using Bind instead of Eval in my HTML, then yes. And the result of your code is no different than my version or what I was doing before, which was just using the findcontrol method, and that just returns what was in the grid when it was first binded to the database on page load. Yes ok i think i know what you are probably doing wrong.
I'd like to know if there are any other ways to retrieve the new values? I have been using the web site successfully for just over a year, and I am presently using a Select button in the row to launch a detailsview, and I edit the database that way. Net a year and a half ago, and VB programmer forever before that, but I feel pretty confident in this large and powerful website I have created, but the users don't like the details view have expressed a desire to edit on the fly in the gridview. My user base has a hold of management's ear, and my management wants to dump ASP. This could be the straw that broke the camel's back - a person's job hangs in the balance - MINE!! If you are databinding in page_load then you need to only do it if(! The difference is much more drastic if each call to the SQL engine has to be done over the network from another process.Again, the benchmark code is available from a gist, and I will paste it to the end of this blog post as well.I've attached my code for what it's worth, but it will probably be too dificult to determine everything that I am doing. Is there a flag I can turn on or off when I am doing row updating so that I can detect and not rebind? This does save a lot of time on the network and all the layers in between.
