<i: Interaction.Behavior> option is not coming for applying beahviour

Question

I have been trying to implement a behavior on a wpf window therefore I have added reference to System.Winodws.Interactivity in my current solution and then wrote the desired behavior. but in order to apply this behavior, I have to write something like this in Windows XAML.

<Window x:Class="WpfApplication5.MainWindow" 
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
        Title="MainWindow" Height="350" Width="525" 
        xmlns:behav ="clr-namespace:WpfApplication5" 
        xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity;assembly=System.Windows.Interactivity">
    <Window.Resources>
        <i:Interaction.Behaviors>
            <behav:DialogIconRemoveBehavior></behav:DialogIconRemoveBehavior>
        </i:Interaction.Behaviors>
    </Window.Resources>
    <Grid>

    </Grid>
</Window>

but this is not valid tag because I might have to add reference to any other assembly apart form System.Windows.Interactivity, So, please suggest what else I have to do in order to use tag in XAML

Answer 1

After wasting my one hour I came to know that only I had to include System.Windows.Interactivity as reference and which I had already done.

the issue was that Behaviors can not be declared in the Resource part of any control.

the moment I took the following

<i:Interaction.Behaviors>

</i:Interaction.Behaviors>

out of the resources then it worked fine.

So, conclusion only System.Windows.Interacivity is the only required.

Never declare that behavior part in the resources or style.

As of 2019, see this and note the namespace is now http://schemas.microsoft.com/xaml/behaviors (previously, like in your question: http://schemas.microsoft.com/expression/2010/interactivity) – Whitecollar
