Question

How can I change the values in XAML based on user input from a textBox? I’m just starting off with WPF/Silverlight and like what most people say, there is a steep learning curve. In the code below I get the result in the picture below.

<TextBlock TextWrapping="Wrap" Width="250">
   <Span FontSize="20">2</Span>
   <Span BaselineAlignment="TextTop" FontSize="14">1/2</Span>
</TextBlock>

But I want the fraction to be the result of a computation. Not static like above. Is it possible to take the value of something computed in a .cs file, and add that value as a variable to the XAML file.

Any answers or points in the right direction would be appreciated. Thanks

Answer 1

Have a look (– actually one look will not be enough –) at data binding, you can create a property which holds the value of the fraction and bind the text to that. If you want actual factions like 1/2 you will probably need a proper struct with an approriate ToString override.
