1.通用静态快捷键绑定命令
cs：
public static Key BtnReferHotKey = Key.F7;
xaml：
<UserControl.InputBindings>
<KeyBinding Key="{x:Static common:Common.BtnReferHotKey}" Command="{Binding CmdSelectFromMaterial}" CommandParameter="{Binding ElementName=DgDataItem}" />
</UserControl.InputBindings>
2.xaml中的计算绑定
xmlns:Cal="clr-namespace:CalcBinding;assembly=CalcBinding"
<DataGridTextColumn Width="130" Header="实际未税价" IsReadOnly="True" Binding="{Binding Cal:Binding MarketPrice*DiscountRate,StringFormat={}{0:f2}}" />
