Aspxgridview updating rows
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.
but Now I don't know how to do edit, update, new, delete function work in MVC4 with aspxgridview.
Please refer these below links: MVC Grid View - CRUD operations example crud in gridview in mvc with sql Grid View - How to implement CRUD operations Few related one: MVC Grid View - How to implement CRUD operations with Data Table Gridview - How to implement CRUD operations Hope these help you learn from scratch.
it just shoes the progressbar runnning and doesn't invokes the updating event ?
Second, when I click a Delete button, I need to loop through and delete only the rows that are checked for delete.
I need to do this only in the web page, and not the database.
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.
