Resize a BorderContainer

[CraigMcDade]

In my old app I resized a ContentPane when a search button was clicked with the following code:

dojo.style(dijit.byId("map"), "height", "83%");

Now I have wrapped the map div in a dijit.layout.BorderContainer with another content pane. The same code structure doesn't seem to work to be able to resize the entire BorderContainer.

Any clues on what I'm missing or how to achieve my goal?

I've posted a better description of what I'm trying to do over at Stack Overflow. Any help would be appreciated. It seems like the TOC widget might be stepping on some of my HTML, but thats just a wild guess.
