This extended text box adds several capabilities to the Framework version, such as autocomplete, data validation, and watermarking.
Watermarks help prompt the user by providing some additional hints on the data that needs to be entered into the text box.
The autocomplete control simplifies data input by providing end users with possible matches as soon as they start typing. There are several modes available to assist data entry: suggest, append, or both.
The suggested text can be appended to the original text or it can be displayed in a drop-down list so that users can choose from different options.
This way, extended text box control can be populated with a predefined list of items, which will assist the user while typing.
Users can choose one item from the filtered list.
There is an option to filter the typed text based on the number of characters.
It is also possible to position the autocomplete pop-up at the top or bottom.
It is also possible to place constraints on the input data.
