Hi Tracy,
Thanks for the response. But i am constructing a string called
Button1, Button2 ... ButtonN and I want to access the element with
the id in mxml document called Button1 which gives me a type error.
So, how can i remove the type error from the following peice of code?
// assuming id's with names Button1 - ButtonN exist
var buttonName:String;
buttonName = "";
for( var i:Number = 1; i <= N ; i++) {
buttonName = "Button"+i;
buttonName.height = buttonName.height + 10;
// What is the right way to set it in flex?
// In JS I would use getElementById(buttonName).height
// What should I use in AS/Flex?
}
Any help is appreciated.
Thanks,
-S-
