Web Data Grid
version 2.0
Web Data Grid is a component written in Javascript and must be used in a
html page to show a dinamic data grid.
Its most important objective is to separate the data from the way to present them
into the page: this purpose is reached loading the data from a special file in
an analogous mode to that XML do, even if the tecnology utilized is different.
Its principal features are:
division of table in several data-pages;
with the keys 

is possible to choose and visualize the data contained into the previous
and the next pages.
data subsequent sorting on the basis of the table's fields;
clicking the left button on every column's header the grid ordering is set according
to the associated field in ascending mode and, clicking the next time, in descending mode;
if you click the right button instead you set the next fields that estabilish the
grid's progressive sorting.
visualized values filtering;
with the key
the row for inserting values to filter the records appear under the table's headers;
Predefinited criterion for every filter's field is "equal to";
to change the criterion you must double-click on the filter's field:
in this way appear a pop-up with the list of every criterion to select;
values for "included", "not included", "on the list", "not on the list" must be separated by the inclusion character defined by the "charInclusive" parameter, that is by default the character "-";
when you've defined all of the filtering rules, filter have to be executed with the key
, to avoid it you have to click on
.
job division between client and server;
for large size databases it's possible to activate server-side functionality:
the records number trasferred to the browser correspond to those visualized for every page only;
sorting and filtering operations are executed from server and works with the same previous point data trasferred division on the base of the records number for page.
