Detailsview itemupdating event
A Form View Update Event Args object is passed to the event-handling method, which allows you to determine the value of an optional command argument sent to the Form View control and to indicate that the update operation should be canceled.The command argument value corresponds to the Command Argument property of the Update button.To cancel the update operation, set the collections, if necessary, before the values are passed to the data source.A common way to use these collections is to HTML-encode the values supplied by the user before they are stored in the data source. For more information about handling events, see NIB: Consuming Events.
This allows you to provide an event-handling method that performs a custom routine, such as HTML encoding the values of a record before updating it in the data source, whenever this event occurs.
Are you able to debug your Event Receiver when you modify an item in the list? It appears no matter what you do to the after properties it doesn't change anything It is nice to update Title in Item Adding and Item Updating events since extra Updates are avoided (without Disable Event Firing), and the "Edit Properties view" will already have the Title filled in Some code example to update title based on filename. For working with Title in Lists, ["Title"] needs to be used.
I have loged the value before an after changing and can see the value change.
A Details View Inserted Event Args object is passed to the event handler, which allows you to determine the number of rows affected and any exceptions that might have occurred.
Hi Everyone, I am having a massive issue trying to get custom data into my DV. I created a Item Updating mode to handle the item update. I create a USER and EMAILUSER class and populated them with their corresponding attributes.
