<?php
class TActiveDataGrid extends TDataGrid 
{
private $_PagingRecord;

public function onPreRender ($param)
{
parent::onPreRender($param);
if(!$this->Page->IsCallBack)
{
$this->getPage()->getClientScript()->registerEndScript("JS".$this->getID(), '
function Paging'.$this->getID().'(command, param)
{
new Prado.Callback(\'callbackPageItem'.$this->getID().'\', 
{CommandName:command, CommandParameter:param}, null,  
{\'CausesValidation\':false, \'onSuccess\': LoadNewData});
}
function LoadNewData(request, result){/*Success*/}
');
}
}

public function onLoad($param)
{
parent::onLoad($param);
$t1 = new TCallBack();
$t1->setID("callbackPageItem".$this->getID());
$t1->attachEventHandler("OnCallBack", array($this, "Paging"));
$this->getParent()->getControls()->add($t1);

$t = new TActivePanel();
$t->setID("DataGridPanel".$this->getID());
$this->getParent()->getControls()->add($t);
$t->getControls()->add($this->getParent()->FindControl($this->getID()));
}

public function getPagingRecord()
{
return $this->_PagingRecord;
}

public function setPagingRecord($v)
{
$this->_PagingRecord = $v;
}

public function Paging($s, $p)
{
if($p->Parameter->CommandParameter=='>') $p->Parameter->CommandParameter = $this->getCurrentPageIndex()+2;
else if($p->Parameter->CommandParameter=='<') $p->Parameter->CommandParameter = $this->getCurrentPageIndex();
$this->setCurrentPageIndex($p->Parameter->CommandParameter-1);
$this->DataSource = call_user_func(array($this->Page, $this->getPagingRecord()), ($p->Parameter->CommandParameter-1)*$this->getPagesize(), $this->getPagesize());
$this->DataBind();
$this->renderDataGrid();
}

public function renderDataGrid()
{
$panel = $this->getParent()->FindControl("DataGridPanel".$this->getID());
$panel->renderControl($this->getPage()->getResponse()->createHtmlWriter());
}

protected function createPagerButton($buttonType,$enabled,$text,$commandName,$commandParameter)
{
if($buttonType==='LinkButton')
{
if($enabled)
$button=new THyperLink();
else
{
$button=new TLabel;
$button->setText($text);
return $button;
}
}
else
{
$button=new THyperLink();
if(!$enabled)
$button->setEnabled(false);
}
$button->Attributes->OnClick = "Paging".$this->getID()."('page', '$text')";
$button->setText($text);
$button->setNavigateUrl("javascript:void(0);");
return $button;
}
}
?>

Hi maisam,

I'm very interested by tour Datagrid, but It doesn't work...
There just the js script of your OnPreRender method wich is parse in the HTML...

rendered HTML code:

Code:

<form id="ctl0" method="post" action="/demos/personal/index.php?page=test"><div>
<input type="hidden" name="PRADO_PAGESTATE" id="PRADO_PAGESTATE" value="eJxVjU0OAiEUg+/CCXgIIz63JsbdXKH8GSK4EHYT7y4zG2JX/Zo2ld5ocsEFHQgGycIYWmAlJTtSk5xT7uwVmHjLLK+HaaxZ+F6kGHyaTDtL3r6NlRoJSnHwrxXP+Oix1pgb6uzQhcUNHfdPDivesczCcbKw+J/s+gH56ji4" />
</div>
<script type="text/javascript" src="/demos/personal/assets/256d30f8/clientscripts.php?js=prado,logger,effects,ajax&amp;mode=debug"></script>




<div>Press ALT-D (Or CTRL-D on OS X) to toggle the javascript log console (<a href="http://gleepglop.com/javascripts/logger/" target="_blank">more info</a>).</div>

<div id="DataGridPanelmeisam"></div><script type="text/javascript">
/*<![CDATA[*/

function Pagingmeisam(command, param)
{
new Prado.Callback('callbackPageItemmeisam',
{CommandName:command, CommandParameter:param}, null, 
{'CausesValidation':false, 'onSuccess': LoadNewData});
}
function LoadNewData(request, result){/*Success*/}

/*]]>*/

Code:

public function Paging($s, $p)
{
if($p->CallbackParameter->CommandParameter=='>') $p->CallbackParameter->CommandParameter = $this->getCurrentPageIndex()+2;
else if($p->CallbackParameter->CommandParameter=='<') $p->CallbackParameter->CommandParameter = $this->getCurrentPageIndex();
$this->setCurrentPageIndex($p->CallbackParameter->CommandParameter-1);
$this->DataSource = call_user_func(array($this->getTemplateControl(), $this->getPagingRecord()), ($p->CallbackParameter->CommandParameter-1)*$this->getPagesize(), $this->getPagesize());

Thanks.  It works.

By the way, I saw you post on http://www.pradosoft.com/forum/index.php/topic,5721.0.html did you managed to resolve the issue? I was falling into that trap too.

Tq.

[gori]

Yes! It's works.

Your $Carma ++;

And now i can add active button to operate with data in grid?

Thanks a lot for fix.

[Knut]

[maisam]

yes, resolved.
use from this method (for example):

Code:

$button->attachEventHandler("onCallback", array($this, "Paging"));

[maisam]

Thanks maisam.

Great! Now avaible for TRepeater
maisam, is it difficult to add dynamic sorting to your component? and how to add Ajax buttons exit/delete/custom ? Can you make small example for me?
Thanks in advance!

[maisam]

hello to all
for insert paging a datagrid,.. into special cell or layer you can not use from activedatagrid
you can user from activepager.

[gori]

So, ActiveGrid is out of date? Ok. Let's use Active pages untill offcial ActiveGrid realise, or i think maisam's become official

I add small function to Active grid for own use, but maybe it will be usefull for someone

Code:

public function Refresh()
{
$this->DataSource = call_user_func(array($this->getTemplateControl(), $this->getPagingRecord()), ($p->CallbackParameter->CommandParameter-1)*$this->getPagesize(), $this->getPagesize());
$this->DataBind();
$this->renderDataGrid();
}

Code:

$this->DataGrid->Refresh();
