DropDownButton and SplitButton doesn't works #2051
Description
Today I've installed MathApps.Metro and trie dto add DropDownButton into a new MetroWindow, but nothing happend. I mean, there is a new control on window, but some properties doesn't work: background always same color (even if I changed it), DropDownList is empty even if it contains some items.
Here how it looks
And here is XAML
<Controls:MetroWindow x:Class="MahApps.Metro.Application1.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:Controls="http://metro.mahapps.com/winfx/xaml/controls"
Title="MainWindow"
Height="350"
Width="525">
<Grid>
<Controls:DropDownButton HorizontalAlignment="Left" Margin="223,107,0,0" VerticalAlignment="Top" Height="89" Width="120" Background="#FFCB4C4C">
<Controls:DropDownButton.Items>
<Button/>
<Button/>
</Controls:DropDownButton.Items>
</Controls:DropDownButton>
</Grid>
</Controls:MetroWindow>
