Hi there…

Okay what I after is how to detect the length of the string populated from array…then auto rescale the height of the title\_mc as shown in my AS as well as the dynamic created textfield …so the textfield will display long string + “newline” for long string…(autowrapper)…

eg:

// for short text keep remain the standard size of height  
mc.title\_mc.tf.text = “short text”;

//for long string it will expandable the title\_mc.height as well…dynamically  
mc.title\_mc.tf.text = “standard width title\_mc”+newline;  
//by the time string move to newline the title\_mc.height also will increase

so how to determines the long string and auto rescale the title\_mc.height

here’s the code currently I’m using…

```auto
