动态将按键绑定添加到按钮

Question

As you can see on this question I need dynamic buttons. Now I need to add some KeyBinding s to those buttons. The shortcuts are stored in my Product class as string. I tried using a ListBox / ListView like I used for creating my buttons, but I can't add KeyBindings there.

Example: Button is bound to object "Coke" where "C" is the shortcut. If I click on this button my OrderCommand command is executed and my bound object is used as its parameter. The same should work if I press "C".

Also I need it to work with dupes, let's say I have two products with the shortcut "C", and if I press "C" not the first button is pressed. Pressing "C" will switch between those two buttons and if I press enter, the Command will be executed.

Answer 1

You can restyle buttons inside the list control to set their InputBindings

<ListBox ItemsSource={Binding Buttons}>
    <ListBox.Resources>
         <Style x:Key="{x:Type Button}" BasedOn="{x:Type Button}">
              <Setter Property="Button.InputBindings"/>
                   <Setter.Value>
                        <KeyBinding Key="C" Command="{Binding OrderCommand}" />     
                   </Setter.Value>
              </Setter>
         </Style>
    </ListBox.Resources>
</ListBox>

Answer 2

you have to define the Keybinding for the command in DataContext that you can do like below:

<Window.InputBindings>
  <KeyBinding Key="C" Command="{Binding OrderCommand}" />
</Window.InputBindings>
