Hi there,
There is an issue working with button click event. The button is put
within DATAGRID as a column AND I have to fetch ID for whichever row
the button is clicked.
Here is the more details.
==================
There is a MXML page named "WhatsOnAdminView.mxml".
In this page there is a method like this.
..
..
<mx:Script>
public function cmdView_click():void
{
Alert.show(grdWhatsOn.selectedIndex.toString());
}
</mx:Script>
..
..
<mx:DataGrid x="10" y="271" id="grdWhatsOn" height="130" width="698">
<mx:columns>
<mx:DataGridColumn headerText="Event" dataField="title" width="350"/>
<mx:DataGridColumn headerText="Type" dataField="articaltypeName"
width="100"/>
<mx:DataGridColumn headerText="Date" dataField="createdDate"
labelFunction="dateFormat" width="100"/>
<mx:DataGridColumn width="148" headerText="View Details"
textAlign="center">
<mx:itemRenderer>
<mx:Component>
<mx:HBox horizontalAlign="center"
xmlns:mx="http://www.adobe.com/
2006/mxml">
<mx:Script>
<![CDATA[
import view.admin.WhatsOnAdminView;
private var obj:WhatsOnAdminView = new
WhatsOnAdminView();
private function
btnClickAction():void{
obj.cmdView_click();
}
]]>
</mx:Script>
<mx:Button label="Open"
click="btnClickAction()" width="80"/>
</mx:HBox>
</mx:Component>
</mx:itemRenderer>
</mx:DataGridColumn>
</mx:columns>
</mx:DataGrid>
..
...
..
In above MXML code look at datagrid code.
There is a 4th column named VIEW DETAILS. For this column I have put
OPEN button as a value for each row. Upon clicking this button I have
to fetch ID (primary key) that was bound with grid during page load.
You would see that finally I am calling the same page cmdView_click()
method to work with grid.
But when I click on button I get following error.
"TypeError: Error #1009: Cannot access a property or method of a null
object reference."
Can somebody advise how to resolve this error?
Thanks in advance.
Regards.
