|
|
Generic HTML template class. Template is a re-usable HTML
|
|
fragment aimed to produce markup as part of a larger
|
|
object (control).
|
|
|
|
Template can either be a simple element or a complex HTML structure
|
|
and may include calls to other templates as part of the output.
|
|
|
|
Templates can access properties of the parent control,
|
|
so the template output will be different depending on
|
|
the control's data. Templates can also accept parameters
|
|
allowing to generate lists or tables of data with the
|
|
single instance of the template.
