Dealing with DOM events

There are some events that will help us to achieve some tasks that are not directly visible through standard events. These are DHTML events and they are invisible in intellisense or properties window of the IDE simply because ASP.NET doesn't know them, and  they will be rendered to the client. There are number of DOM events as such and you can find more details in the MSDN site.
