Hello there, could I get some help on troubleshooting why MouseDoubleClick is not working, here are some context:

I created an inventory grid with slots in it, the slot (item) has a few interactions:

Hover, Click - Different visual states, and they are handled via Visual State Manger
Drag to move the item - it's a custom function we created to allow players to drag item to a different spot in the inventory. But this function listens to MouseLeftButtonDown / MouseLeftButtonUp

We need to create a different way to equip an item from the inventory grid, we thought double clicking is the most natural way to do that.

<b:EventTrigger EventName="MouseDoubleClick">
                    <b:InvokeCommandAction
                        Command="{Binding DataContext.EquipItem, ElementName=InventoryRoot}"
                        CommandParameter="{Binding}">
                    </b:InvokeCommandAction>
                </b:EventTrigger>

This is where it stops working, If the event is MouseDoubleClick, it wont do anything, but if I do MouseEnter, the command will work, so I know the command and the binding are correct, it's just the double click is not being listened.

Hello, the DoubleClick event is defined by the Control class, so you'll have to set the EventTrigger in a Control-like element, for example:

<ContentControl>
  <b:Interaction.Triggers>
    <b:EventTrigger EventName="MouseDoubleClick">
      <b:InvokeCommandAction .../>
    </b:EventTrigger>
  </b:Interaction.Triggers>
  <Grid>...</Grid>
</ContentControl>

Could you try that?

Thanks for looking into this. I added a ContentControl to the listboxitem template, and wrapped everything within it. Unfortunately, MouseDoubleClick is still not firing, but MouseEnter works with this setup as well.

Is your integration properly injecting Double Click events to the View?

    /// Notifies that a mouse button was double clicked. Origin is in the upper-left corner.
    /// When a double click happens the following sequence of events are expected:
    ///  - MouseButtonDown (first click)
    ///  - MouseButtonUp
    ///  - MouseDoubleClick (second click)
    ///  - MouseButtonUp
    /// See https://docs.microsoft.com/en-us/windows/win32/learnwin32/mouse-clicks#double-clicks
    /// Returns true if event was handled
    virtual bool MouseDoubleClick(int x, int y, MouseButton button) = 0;

Could you please verify this with the person in charge of the integration?
