lets start from zero:
[list=1][]Create a table named:  player with 3 columns:  idplayer, firstname, lastname,  and add some players to it:[list=1][][indent]
idplayer	firstname		lastname[/indent][indent]
----------------------------------------------------------------[/indent][indent]
1, 		‘name player 1’, 	‘last name player 1’[/indent][indent]
2, 		‘name player 2’, 	‘last name player 2’
[i]
[/i][/indent][/list][*]using Gii, create a model named [b]Player.php
[/b][]again using Gii, create a controller for that model, name: ‘player’, with an action: ‘list’[]Creates the actionList on player controller:
public function actionList()
	{
		// for demo propouses, list all players
		$dataProvider = Player::model()->search();
		$this->render('list',array('dataProvider'=>$dataProvider));
	}
[*]In your view:  views/player/list.php (this file was created by Gii when you creates your controller, step 3) put the following:[/list]
[indent]
<h1>My Players</h1>
<?php
$this->widget('zii.widgets.grid.CGridView', array(
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'idplayer',
        'firstname',
        'lastname',
    ),
));
?>
[/indent][indent]
[/indent][indent]6. Test your view:  http://localhost/tes...p?r=player/list   (use your own URL) it will display a CGridView with your players created in step 1.
[/indent][indent]7. Create a new action in your player controller, named: ‘actionAjaxCreate’[/indent]
[indent]
	public function actionAjaxCreate() {
		$p = new Player();
		$p->firstname = 'new Player firstname';
		$p->lastname = 'new Player lastname';
		if($p->save()){
			echo "OK"; // echo or not, if an exception dont occur then is OK.
		}
		else{
			throw new Exception("Sorry, cant create a player",500);
		}
	}
[/indent]
[indent]
- create a "New Player" Button with auto refresh of your grid:[/indent]
[indent]
<h1>My Players</h1>
<!--  CODE TO INSERT NEW PLAYER BEGINS -->
<div id='results'>...</div>
<script>
	function allFine(data) {
		// display data returned from action
		$("#results").html(data);
		// refresh your grid
		$.fn.yiiGridView.update('player-grid');
	}
</script>
<?php echo CHtml::ajaxButton("Insert New Player", array('player/ajaxcreate'), array('success'=>'allFine')); ?>
<!--  CODE TO INSERT NEW PLAYER ENDS -->
<?php
$this->widget('zii.widgets.grid.CGridView', array(
	'id'=>'player-grid',
    'dataProvider'=>$dataProvider,
    'columns'=>array(
        'idplayer',
        'firstname',
        'lastname',
    ),
));
?>
[/indent]
[indent]
- test it.  It works fine, and will insert a new player refreshing your grid inmediatly.[/indent]
