WPF 一种带有多个子集的类ComBox 解决方法
在最近的工作中遇到很多，类似这种layUI风格的Combox：
因为WPF原本的控件，并不具备这种功能，尝试重写Combox的模板，发现无从下手。
于是尝试从多个控件组合来实现这个功能。
这里使用了Popup 来存放数据，发现还不错。
将popup分为三列，每个列的列宽设置位自动，当点击其中一个选项的时候，检索所选，根据字典查到数据，再加载其他列。
即可实现这种效果
代码如下：
UI：
<Button x:Name="btn1"
Height="54"
Margin="0,10,0,0"
Click="Button_Click">
<Button.Template>
<ControlTemplate TargetType="{x:Type Button}">

<TextBlock

Margin="10,0,0,0"
VerticalAlignment="Center"
Foreground="White"
FontSize="32" />
</Grid>
</Border>
</ControlTemplate>
</Button.Template>
</Button>
