Summary: In this video, we are covering three points: Control tree,
AssociatedControlId, and Literal control. First we start with the control tree.
To do that, we created a page that contains few controls (label, dropdownlist,
and a button). Then we added trace=true to the page so that the trace
information will show when we load the page into the browser. This trace
information is very helpful for debugging specially when we look at the control
tree and see how the page is structures. Next, we look at the label control. We
created a label control with a textbox. We view the source in the browser and
see that the label turns into a span tag with all the properties that we set.
After that, we added the property AssociatedControlId to associate the label
with the textbox (helpful for hearing aid technologies). Doing that help us see
the label staying as a label when displayed into the browser (instead of a
span). Finally, we looked at the literal control to dynamically affect the
display of the title.

conceptualization of new technology, which has good coding standard and
simplified design to illustrate the key points.
