Larger ModernButton w/ IconData from versus standard button w/ PNG icon

Apr 9, 2013 at 7:51 PM
I'm trying to get a larger ModernButton using the IconData that is available from, however those appear to be sized specific for the WP7/8 app bar.

What would be the best way to get a a larger icon?

I have thought about using the PNGs that are available from the download and just using that as the a standard button's image, however I am not what I would do upon detecting that the ThemeSource has changed and thus I would need to swap out each button's image (light or dark depending on the current theme).

any ideas what I could do here?

The nice thing about using the IconData for the icons in a ModernButton is that it works regardless of which theme is being used.

I have not yet used the ModernButton, but maybe you should have a look at Syncfusion MetroStudio (it's free!). You can export to XAML, so the icons scale as you like. I really like it :)

All icons from come with a XAML version as well (located in the xaml folder). The vector based paths can be stretched to any size you like and support changing themes as well.

How exactly do I stretch these vector based paths? Simply changing the width/height of the button in my page's xaml doesn't seem to work. Is this something I need to do in blend (stretch the icon) to get the new path data that I can use on the button? I've never used blend, so I am not exaclty how to work with xaml icons..

ModernButton has a default style (in Themes\ModernButton.xaml) that has a Grid with a fixed size of 18x18px for icons. Furthermore the IconWidth and IconHeight properties are used to properly size icons within this grid. For larger icons you'll need to create a custom ModernButton style and set your own sizing.

Try applying a ScaleTransform like this:
<mui:ModernButton IconData="F1 M 42.3542,38L 26.5208,53.8333L 37.2083,53.8333L 53.8333,38L 37.2083,22.1667L 26.5208,22.1667L 42.3542,38 Z ">
        <ScaleTransform ScaleX="5" ScaleY="5"/>
