This is a very useful feature for
any graphical user interface which makes it easy for users to fill in
applications or forms by suggesting them suitable words or phrases in
appropriate text boxes. So, while it may look like a tough job; its actually
quite easy to use this feature. The text boxes in C Sharp contain an
AutoCompleteMode which can be set to one of the three available choices i.e.
Suggest , Append or SuggestAppend. Any choice would do but my favourite is the
SuggestAppend. In SuggestAppend, Partial entries make intelligent guesses if
the ‘So Far’ typed prefix exists in the list items. Next we must set the
AutoCompleteSource to CustomSource as we
will supply the words or phrases to be suggested through a suitable data source.
The last step includes calling the AutoCompleteCustomSouce.Add() function with
the required. This function can be used at runtime to add list items in the
box.
