问题 in my Windows Phone 8.1 application I have a RichTextBlock with Hyperlinks in it. I've added some block of code in the click event of the Hyperlink. The problem is that whenever I click on the Hyperlink, my application crashes with an 'Access Violation' exception. This only happens when the keyboard is visible.

阅读更多关于 UWP: Compute text height in a RichTextBlock gives weird results

问题 I need a reliable method to get the height of the text contained in a RichTextBlock , even before it is actually drawn on the scene. Using the normal Measure() method produces a weird result, as it can be seen in the MVCE: https://github.com/cghersi/UWPExamples/tree/master/MeasureText (I want to keep fiexed the width, and measure the final height, but the result of DesiredSize is far different from the actual height!!).
