Re: DataTable cell link

[Michael O'Cleirigh]

Hi Daniel,

If you subclass DefaultDataTable there is a protected method call 
newCellItem(...) that you can use to attach the onclick class onto the <td>.

like:

class MyDataTable extends DefaultDataTable {
/* (non-Javadoc)
    * @see 
org.apache.wicket.extensions.markup.html.repeater.data.table.DataTable#newCellItem(java.lang.String, 
int, org.apache.wicket.model.IModel)
    */
   @Override
   protected Item newCellItem(String id, int index, IModel model) {


       Item cell = super.newCellItem(id, index, model);


       cell.add(new AttributeAppender("onclick", new Model 
("someJavascriptCall();"));

       return cell;
   }
}

Alternately you can use a custom column implementation like the 
FragrementColumn and add the onclick when the cell is created like:

class MyOnClickColumn extends AbstractColumn {
...
public void populateItem(Item cellItem, String componentId, IModel rowModel)
   {
      Label cell = new Label(componentId, new PropertyModel(rowModel, 
property))

       cell.add (new AttributeAppender("onclick", new Model 
("someJavascriptCall();"));

       cellItem.add(cell);
   }
}


I think the second version would attach the onclick to the label within 
the <td></td> of a cell.

Regards,

Mike
I dont know wicketopia project (and any of its classes like FragmentColumn)
so I can misunderstand your idea but as far as I am able to read that code
It looks like you are adding a link to the table cell, not making a cell
itself a link.

If I understand your code it is familar to:

<td>&lt;a&gt;text&lt;/a&gt;</td>

but Im wondering how to achive:
<td on click="xyz">text</td>

where xyz is code generated by Wicket (like in Link component class)

If I misundestood you could you give me some more details hot to make cell
itself a link ? (not adding a link to the cell) ?

Regards 
Daniel

Hi

I have one short question:
How to make entire cell in a DataTable a link ?
I've read that Link component can be attached not only to &lt;a&gt; tags
but
also to any other html elements (like <tr> and <td>) but I dont know how
to
use it with DataTable API.

Regards Daniel
