Boolean CommandParameter in XAML
This might be a bit of a hack but you can derive from the KeyBinding class:
public class BoolKeyBinding : KeyBinding{ public bool Parameter { get { return (bool)CommandParameter; } set { CommandParameter = value; } }}Usage:
<local:BoolKeyBinding ... Parameter="True"/>And another not so weird solution:
xmlns:s="clr-namespace:System;assembly=mscorlib"<Application.Resources> <!-- ... --> <s:Boolean x:Key="True">True</s:Boolean> <s:Boolean x:Key="False">False</s:Boolean></Application.Resources>Usage:
<KeyBinding ... CommandParameter="{StaticResource True}"/>
The easiest is to define the following in the Resources
<System:Boolean x:Key="FalseValue">False</System:Boolean><System:Boolean x:Key="TrueValue">True</System:Boolean>and use it like:
<Button CommandParameter="{StaticResource FalseValue}"/>
Or, maybe that:
<Button.CommandParameter> <s:Boolean>True</s:Boolean></Button.CommandParameter>Where s is the namespace:
xmlns:s="clr-namespace:System;assembly=mscorlib"
