row expression

Being able to set per row attribute expressions in GridView etc would be handy.

I’m trying to add a value attribute (I know it’s not valid) so it can be used by some js and i’m currently using


'rowCssClassExpression' => '"\" value=\"" . $data->dataID'

which doesn’t look too elegant.

I needed this too and ended up extending CGridView. I had to completely override renderTableRow and I’m not too fond of it either.


public function renderTableRow($row) {


	$data = $this->dataProvider->data[$row];


	if($this->rowTitleExpression !== null)

		$title = CHtml::encode($this->evaluateExpression($this->rowTitleExpression, array(

			'row' => $row,

			'data' => $data

		)));


	if($this->rowCssClassExpression !== null)

		echo '<tr class="'.$this->evaluateExpression($this->rowCssClassExpression, array(

			'row' => $row,

			'data' => $data

		)).'"'.

		($title ? ' title="'.$title.'"' : '').'>';

	else if(is_array($this->rowCssClass) && ($n = count($this->rowCssClass)) > 0)

		echo '<tr class="'.$this->rowCssClass[$row % $n].'"'.

		($title ? ' title="'.$title.'"' : '').'>';

	else

		echo '<tr>';


	foreach($this->columns as $column)

		$column->renderDataCell($row);


	echo "</tr>\n";

}

IMPORTANT: If somebody’s using this, please note that you won’t get a title-tag when there is no rowCssClass- or rowCssClassExpression-property!

So yes, I too think that would be a useful feature!
