Question

I’m trying to bind the checkbox checkchange event to a command – MVVM
Why doesn’t this work? or do anything while the same works on button?

<CheckBox x:Name="radRefresh" IsChecked="{BindingREADY, Mode=TwoWay}" Command="{Binding Refresh_Command}" Content=" Refresh "  Margin="10,25,0,0"  />

<Button Command="{Binding Refresh_Command}" />

thanks

This will work…


<i:Interaction.Triggers>
<i:EventTrigger EventName="Click">
<cmd:EventToCommand Command="{Binding Path=YourCommand,Mode=OneWay}" CommandParameter="{Binding IsChecked, ElementName=YourCheckBox}"></cmd:EventToCommand>
</i:EventTrigger>
</i:Interaction.Triggers>


where i is

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

Add namespace for cmd

    xmlns:cmd="clr-namespace:GalaSoft.MvvmLight.Command;assembly=GalaSoft.MvvmLight.Extras.WPF4"

This is one of the preferred ways for MVVM if you are utilizing the MVVMLight Framework.
