Filter grid component using a textfield and listener method

[Eldred Mullany <el...@easypay.co.za>]

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. Even with a search
functionality, my result set returned from the search will still be very
big. So by allowing the user to type in the specific value,that would
filter the list more effectively. 

 

Is this possible in T5.0.1.5?

 

Thanking you in advance.

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>

Take a look at GridDataSource to allow efficient searches.
