Row updating event in grid view

the good old problem of getting the data from the row that is being currently edited within a Grid View. Accessing the "Controls": This method gets you access to the control in the Grid View, which might be useful based on what you are doing.Obviously the simplest method is to use Data Key Names on the Grid View and then you should have the data in your Grid View Update Event Args as part of e. (In the following example, I cast to a Check Box as I know I have a checkbox at the col Index You Are Interested In - you should cast to whatever control you have in that column).

But for this demo, I’ll show you the simple version, that also doesn’t work 🙂Let’s bind the data to our Grid View and have it autogenerate our columns, as well as an edit button.

When we edit a row in our Grid View and press the “Update” button, at some time it’s received in the Row Updating method.

But as I noted in the comments in that method, some collections that should contain the columns (names, old values and new values) are always empty. And the Row Updated method is never even touched!!! NET Forums that I need to use a Data Source control.

Row Updating event, doesn’t work as all samples say it should do.

All samples of course assume you’re doing everything in your page, but I have to do everything in my code-behind, because on forehand I don’t know what I’ll be binding to my Grid View.

Check out what I’m trying to do, maybe you can help?

First, I load up some data: After that, I’m doing some work to make my Grid View look beautifull, adding all columns by hand.

In my case this was happening because I was binding to a List of custom objects.

Note A common mistake that a lot of people do is that they perform a databind each and every-time the Page_Load method is called.

This will lead to problems like "Grid View does not show updated values", "Grid View looses values changed by user". In your Page_load, this is typically only inside a block where you check to make sure that Page_Load is not being called during a post-back call.

For a while now I’m trying to figure out why my method, triggered by the Grid View.
