Hi I'm new in flex, I think my datas are already displayed in my datagrid because there is already a scroll bar in my datagrid only, it is not visible. I haven't set it as visible="false". If you want to clearly understand my question, I've uploaded the screenshot of my datagrid. (I can't clearly state my question properly because I'm having a hard time in speaking in English, I'm not an American..)

I will just show you my code..:D

(mxml code)

<mx:DataGrid width="584" height="172" horizontalCenter="0" verticalCenter="1" id="dgcandidate" dataProvider="{cangrid.lastResult.datas.data}" creationComplete="cangrid.send()">
                                <mx:columns>
                                    <mx:DataGridColumn headerText="canid" dataField="id1" visible="false"/>
                                    <mx:DataGridColumn headerText="Last Name" dataField="ln1"/>
                                    <mx:DataGridColumn headerText="First Name" dataField="fn1"/>
                                    <mx:DataGridColumn headerText="Year" dataField="yr1"/>
                                    <mx:DataGridColumn headerText="Course" dataField="kurs1"/>
                                    <mx:DataGridColumn headerText="Position" dataField="pos1"/>
                                </mx:columns>
                            </mx:DataGrid>

<mx:HTTPService id="cangrid" url="cangrid.php" useProxy="false" showBusyCursor="false" method="POST">
    <mx:request xmlns="">
    </mx:request>
</mx:HTTPService>

this is my php code  in connecting with my flex (cangrid.php)

$query  = "SELECT candidate.candidateid, candidate.lastname, candidate.firstname, candidate.year,candidate.course,position.description
FROM candidate inner join position where candidate.positionid = position.positionid";

$result = mysql_query($query);

print "<datas>";
    while ($recordset = mysql_fetch_object($result) ) {
        print "<data><id1>".$recordset->canID."</id1>
           <ln1>".$recordset->canLname."</ln1>
               <fn1>".$recordset->canFname."</fn1>
        <yr1>".$recordset->canYr."</yr1>
        <kurs1>".$recordset->kurs."</kurs1>
           <pos1>".$recordset->canPos."</pos1>
       
        </data>";
    }
print "</datas>";
