[flexcoders] Failed to disable shadow of ToolTip...

[sanjaypmg]

Hi, 

I want to remove shadow of the tooltip in my flex screen but failed 
to do the same... I have used 

(In MXML file)

StyleManager.getStyleDeclaration("ToolTip").setStyle
("dropShadowEnabled",false); 


or

StyleManager.getStyleDeclaration("ToolTip").setStyle
("dropShadowEnabled","false"); 


(In CSS file)

ToolTip { 
  dropShadowEnabled: false;
}

But It is not working.....

Can anyone pls do let me know, how can I remove the shadow from the 
tooltip.

Thanks in Advance,
Sanjay Sharma
