WPF 绑定注意事项二

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}}" />
