If you can, use 2 way databinding, if your control doesn't have a useful property to bind against and you need to do some more logic to get the right value then use Find Control.
I Often see people abusing find control and not understand that it is NOT recursive by default and complain when code like this Throws a null reference exception.
My advice is use Use Find Control as a last resort.
event is raised when a row's Update button is clicked, but before the Grid View control updates the row.
This enables you to provide an event-handling method that performs a custom routine, such as canceling the update operation, whenever this event occurs.
Each data control has a method which is responsible for populating a dictionary of name value pairs from field name to value.
Here is a mapping of data control to method used to extract values: Grid View = public Extract Item Values As we can see with the exception of List View these oh so useful methods are protected, that means we can't call them from our code if we are using these built in controls.
A Grid View Update Event Args object is passed to the event-handling method, which enables you to determine the index of the current row and to indicate that the update operation should be canceled.
To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.
Uses Most data controls support writing custom commands and handling some Command event(Row Command for Grid View).Tags: Adult Dating, affair dating, sex dating
