>I've created a nice hierarchical grid by instantiating a set of containers, one per level. The container holds the usual textbox, and both the container and the textbox are transparent, so the underlying color shows through (colors denote levels, as does the textbox's .left). The dynamicCurrentControl is decided by hierarchy level.

However, the textbox permanently have .fontbold=.f. and I don't really know how to make this happen (short of evaluating the DynamicFontBold expression of the column, which I expect may be slow). [update: it actually doesn't work, as I have to set it in the refresh of the container, and so it works only for the current row's container]

Hmmm.. I'm not sure whether I fully understand your grid's structure. Anyway...
First I imagined that if you don't use DynamicFontBold, that DynamicFontBold will be False all the time and dynamically set the font to non-bold all the time, no matter what you do elsewhere. After some experimenting I now think that DynamicFontBold is not tested if not specified (hence the REAL default (None), which by the way is not documented).
This opens the way to setting the fontbold in another way, but everything that I tried would only influence the fontbold of the WHOLE column. Perhaps you can define a Text2, set its fontbold to True and then influence CurrentControl.
