我可以在控件中容纳多少个字符，WP7 Silverlight

Question

I want to take a dynamic string of text, and break it up so that it will fit in one or more textboxes or textblocks. Preferably textboxes. So let's say I get a string of text thats 132 characters long, but I can only display 40 characters in the textbox before it goes out of view. So, I want to break up the text into 4 textboxes. I want to find out programatically how many characters can be displayed.

I tried ActualWidth, but get 0.0.

There isn't a way to measure text on the phone. If you were only ever going to use a fixed text size you could measure all the characters in advance and calculate accordingly.

However, you may find it easier to use the same method as in http://nerdplusart.com/texttrimming-textblock-for-silverlight to override MeasureOverride and trim the text until it fits.
