Columntemplate: format tpl text

Hi!

I intend to build a component constituted by a border layout with a grid in the center, and a detail panel on east.

This means that the width of the grid (and the rows tpl) change when the detail east panel collapses.

The problem to solve is to format the text widthin tpl, so that fit the width of the row and do not exceed the limits, as happens now.

Fiddle:

How to solve this?

Thanks in advance.
