Server controls like Datagrid, DataList, Repeater can have other child controls inside them.
for example, DataGrid can have combo box inside datagrid.
These child control do not raise there events by themselves, rather they pass the event to the container parent (which can be a datagrid, datalist, repeater), which
is passed to the page as “ItemCommand” event. As the child control send there events to parent this is termed as event bubbling.

Shadowing:
When two elements in a program have same name, one of them can hide and shadow the other one. So in such cases the element which shadowed the main element is referenced.
