Gridview rowupdating new value

So what you need to do is store the data source (maybe in Session) and only bind rebind the data when you absolutely need to (Like during the Is Not Post Back) Do you understand?

When I click edit on the grid and change the value of the textbox and click update the label will just display the original value of the textbox. "When I click edit on the grid and change the value of the textbox and click update the label will just display the original value of the textbox." So lets say there is "test" in the textbox originally and then I edit it to "asd" then click update.

Now, when an user edit a row then click update, I'm having problem getting the new values in gridview's rowupdating event, it always returns the old values. With that being said you could go directly after the form post data perhaps, i usually find it's easiest to debug then search through and find your key value pair. I'll take a closer look at your posts maybe tomorrow, and definitely Monday, but I'm just a hack, and I so close to dumping this whole thing and lettting someone else do it...whooops there isn't anyone else... The new values are not being retrieved, just the old values. Excuse my crude Msg Box methos; it only goes to prove what a hack I am. Controls Dim dcfc Cell As Data Control Field Cell = o Ctl If dcfc Cell Is DBNull. Controls Dim cell As Data Control Field Cell = Try Cast(control, Data Control Field Cell) If cell Is Not Nothing And Also cell. By the way, when I attempted to cut and paste your code, the compiler would not accept the arguments (String, Object) at the end of IDictionary, saying that IDictionary has no parameters, and also in the return values portion below it complains that Dictionary is not a type. Dictionary is a generic type and you have to include System. I'm not sure whats going on in your case Yes I am getting the exact data that's in the edit row. It's a record that looks similar to the other data in the database, but it is defintiely different values so I am confident that I am looking at the edit row.

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.

Without seeing your markup, it's hard for me to tell if you've created .

Although this isn't as big of a problem when you're referencing the text from web controls, getting in the habit now will prevent you from serious headaches and inefficiently checking for null and empty later. NET 4.0, you should have access to event, you need to pull the new values out of the front-end controls, and then re-bind your data.

If I had written the code, I would explicitly create all the front-end controls and use a binding command (if you aren't familiar, it looks like How should I create all front-end controls in the markup?
