Question

I have this xaml:

<DataGrid.InputBindings>
        <KeyBinding Key="a" Command="{Binding Path=Function}" CommandParameter="{Binding ElementName=dataGrid1,Path=SelectedItem}"></KeyBinding>
        <KeyBinding Key="s" Command="{Binding Path=Function}" CommandParameter="{Binding ElementName=dataGrid1,Path=SelectedItem}"></KeyBinding>
</DataGrid.InputBindings>

When i select a row and press a or s i bind the selected item to KeyPressed. My problem is how can i know which key i have pressed ? (I want to bind key pressed and selected item)

If you have 2 keybindings, it would be more clear to have 2 distinct commands :

<DataGrid.InputBindings>
    <KeyBinding Key="a" Command="{Binding Path=ACommand}" CommandParameter="{Binding ElementName=dataGrid1,Path=SelectedItem}"></KeyBinding>
    <KeyBinding Key="s" Command="{Binding Path=SCommand}" CommandParameter="{Binding ElementName=dataGrid1,Path=SelectedItem}"></KeyBinding>
</DataGrid.InputBindings>
