Let's say I have a rectangle, the size of which has been computed at runtime. Now, I want to use XTP / XAML to draw a string into that rectangle using the largest font size that will fit.

Does anyone have any suggestions for computing the maximum font size as efficiently as possible?

My first thought was to use XTPMarkupMeasureElement to measure an CXTPMarkupUIElement object in a loop, increasing the XAML FontSize attribute until it no longer fits. But this strikes me as being fairly inefficient. I suppose this could be further improved through use of a binary search technique (e.g. to reduce the number of test cases).

Anyone know a better way?

I also see only this way.
