None of them feels natural to me, so quite frequently - especially if I haven't written that code in a while - I spent way more time than I should rediscovering what approach I should use the hard way.So I'm taking a few minutes - for my own sake - to write this stuff down so I can look it up next time I have a brain fart Using a Button Field you can specify a Command Name which in turn provides the On Row Command event some context as to what type of operation you are dealing with in Code Behind.For a while now I’m trying to figure out why my method, triggered by the Grid View.Row Updating event, doesn’t work as all samples say it should do. As the values are inserted into an Ordered Dictionary - you can use the field names to access the changed data 2.
Therefore the Check Box_Check Changed and Drop Down List_Selected Index Changed events where not being fired.
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.
I don't know about you, but I cringe every time I need to create a Grid View based layout that needs to create a few custom link handlers off that grid.
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.
