Execute a command when the Enter key is pressed

[Method]

<telerik:RadMaskedNumericInput Value="{Binding Quantity, Mode=TwoWay}">
    <telerik:RadMaskedNumericInput.InputBindings>
        <KeyBinding Key="Enter" Command="{Binding DoSomethingCommand}" />
        <KeyBinding Key="Tab" Command="{Binding DoSomethingCommand}" />
    </telerik:RadMaskedNumericInput.InputBindings>
</telerik:RadMaskedNumericInput>

I am trying to call to a command when the Enter key is pressed like an exemple above.
The Tab KeyBinding works perfectly, but the Enter doesn't work.

This behavior works in a TextBox, is this possible in a MaskedInput?

[Method]

 Problem solved.

 I just set the property AcceptsReturn to False.
