windows phone 7 - Check if the WrapPanel is overflowed? -

i'm doing pagination things. know if can check whether textblock inside of wrappanel overflowed or not? way ask if know pagination please give me tuts. i'm doing split big sized string pages , display them phone screen. thanks.

microsoft.phone.controls.wrappanel wrappanel = new   microsoft.phone.controls.wrappanel(); wrappanel.width = calculatedwidth; wrappanel.height = calculatedheight; wrappanel.margin = new thickness(pageformat.leftmargin,pageformat.topmargin,pageformat.rightmargin,pageformat.bottommargin);  textblock tbl = new textblock(); tbl.text = " text here ... ";  wrappanel.children.add(tbl); 

since mango sdk, there property call texttrimming.

so xaml

<textblock text="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaa" texttrimming="wordellipsis" width="200" /> 

will produce somehting "aaaaaaa....."

so code like:

tb1.textwrapping=textwrapping.wordellipsis

edit there property called wrap u can set both in xaml , c#. <textblock text={binding text} textwarapping="wrap" />

or in c# as

mytextblock.textwrapping=textwrapping.wrap;
