Bitesized tidbits for building Modern (Metro) apps.
When creating your awesome layout to your awesome new app, you’ll often use Grids as a way of ensuring things are placed where you want them to be and you’d most likely use the ColumnDefinitions and RowDefinitions. Using these has a number of benefits, not least letting you specify exact heights/widths for your columns/rows, but you can also use Auto and the * values to set screen percentages. What this means is you can have a very exact UI or one that adapts as the size of the window changes.
Adapting to the size of the window is something that’s more relevant to UWPs than ever before with you bringing one UI to all possible screens the user can use your app on. But what if you still want to keep some rows at a certain screen percentage until the user hits a trigger point? Well, a small, but subtle change to xaml now allows you to do more with your Column/RowDefinitions.
