Hi, I would like to bind some events to some relay commands that I have defined using MVVM. I have installed the nuget package for xaml behaviors but it's absolutely not triggering my command 😦

xmlns:behavior="http://schemas.microsoft.com/xaml/behaviors"
 <Grid>
        <TreeView ItemsSource="{Binding RootNodes}">
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate ItemsSource="{Binding Items}">
                    <TextBlock Text="{Binding Title}">
                        <behavior:Interaction.Triggers>
                            <behavior:EventTrigger EventName="MouseClick">
                                <behavior:InvokeCommandAction Command="{Binding Mode=OneWay, Path=Action}"/>
                            </behavior:EventTrigger>
                        </behavior:Interaction.Triggers>    

                    </TextBlock>
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>
    </Grid>

xmlns:behavior="http://schemas.microsoft.com/xaml/behaviors"
 <Grid>
        <TreeView ItemsSource="{Binding RootNodes}">
            <TreeView.ItemTemplate>
                <HierarchicalDataTemplate ItemsSource="{Binding Items}">
                    <TextBlock Text="{Binding Title}">
                        <behavior:Interaction.Triggers>
                            <behavior:EventTrigger EventName="MouseClick">
                                <behavior:InvokeCommandAction Command="{Binding Mode=OneWay, Path=Action}"/>
                            </behavior:EventTrigger>
                        </behavior:Interaction.Triggers>    

                    </TextBlock>
                </HierarchicalDataTemplate>
            </TreeView.ItemTemplate>
        </TreeView>
    </Grid>

Why is my RelayCommand Action not triggered?

step 1: check for binding errors step 2: confirm that MouseClick is the proper event

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
