Dynamically Set the height of DataGrid

[Sannyasin Brahmanathaswami]

I am slowly getting into datagrids. Doing my homework at lessons.livecode.com.

I can't find a reference for doing the following:

How to you get a datagrid with 2 to 12 rows to "dynamically" resize itself depend on how many rows it has?  And, if has more then 12, don't resize and turn vertical scroll on. (both mobile and desktop) ?  the idea is to hide the datagrid, set its dgtext array, resize it and have to appear as a kind of contextual window.
