Hi,
Hi!
I would like to filter a grid component by typing in a string into a
text field that has listener method that filters the results dynamically
without any method calls to the database.
Tapestry does not support this out of the box yet. One suggestion: put
your Grid inside a Zone. Use a Form to update this zone automatically.
Then use a little bit of JavaScript to submit the form when the text field
is updated. Some not tested code:
<form t:type="Form" t:zone="zone">
<input t:type="TextField" t:id="search" id="search">
<input type="submit" id="submitForm"/>
<script type="text/javascript">
Event.observe('search', 'keyup', function() {
$('submitForm').click();
});
</script>
</form>
<div t:type="Zone" t:id="zone">
<table t:type="Grid" ...>
</table>
</div>
Even with a search
functionality, my result set returned from the search will still be very
big.
Take a look at GridDataSource to allow efficient searches.
