flex textflow dyniamic height

Question

Hi,

In my flex application I have scenerio like this: parent to child Vbox->Canvas->Sprite->Textflow

In this scenerio now I need to have dynamic height of the textflow & its parents. Here the root parent is the itemrenderer of the datagrid I have.

I need the heights of rows to be adjust according the content in it.

Right now I am importing the xml to textflow, then getting the number of lines, text height. Then removing the textflow & adding it again with the measured height according to the number of lines & text height.

How can I achieve it without removing & adding it again, coz it is taking much time in updating?

Thanks in advance.
