After googling i got some idea about this ,,means PreRender is the event that takes place just before the HTML for a given control/page is generated (to later be sent to the browser). So by setting an item.Visible = false here it will not be rendered to the HTML (however it's ViewState will). In this case it looks like the code is hiding all rows in the RadGrid when a user is editing/inserting an item I presume for less distractions for the end user.
