Hi Jagadesh,
U can hava a java that extends Grid.. Let's say:
public class MyGrid extends org.apache.tapestry5.corelib.components.Grid {
}
The class doesn't have anything inside...
For this class u create a template that overrides the Tapestry Grid.
Something like this:
MyGrid.tml
<div class="t-data-grid" xmlns:t="
http://tapestry.apache.org/schema/tapestry_5_0_0.xsd";>
<div t:id="pagerTop"/>
<table t:id="table">
<thead t:id="columns"/>
<tbody>
<tr t:id="rows"/>
</tbody>
</table>
<div t:id="pagerBottom"/>
<t:block>
<div t:id="pager"/>
</t:block>
<t:block id="empty">HERE IS YOUR DEFAULT BLOCK</t:block>
</div>
Maybe there is a way to do it without rewriting all the tml. But i'm not
aware of it.
I Hope it helps
