Question

I am trying to bind the SelectionChanged event of ComboBox using RoutingCommand(same as we bind the command for Buttons). But not able to achieve it. I dnt like to use any third party control or to write the code in the property.

Answer 1

You can use System.Windows.Interactivity dll.

The code will be something like that:

<UserControl
 ...
 xmlns:ei="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"
 ...>    
 ...
 <Combobox>
    <ei:Interaction.Triggers>
       <ei:EventTrigger EventName="SelectionChanged">
           <ei:InvokeCommandAction Command="{Binding Command}"/>
       </ei:EventTrigger>
    </ei:Interaction.Triggers>
 </Combobox>
 ...    
</UserControl>
