Is it possible to add a DiscreteObjectKeyFrame into CompoundSettings.Sequence?

[GF-Huang]

What I want to do?

• Set Visibility to Visible before FadeIn.
• Set Visibility to Collapsed after FadeOut.

In vanilla way, it looks like this:

<Style TargetType="hc:SimplePanel">
  <Setter Property="Visibility" Value="Collapsed" d:Value="Visible" />
  <Style.Triggers>
    <DataTrigger Binding="{Binding IsLoading}" Value="True">
      <DataTrigger.EnterActions>
        <BeginStoryboard>
          <Storyboard>
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility">
              <DiscreteObjectKeyFrame KeyTime="0:0:0" Value="{x:Static Visibility.Visible}" />
            </ObjectAnimationUsingKeyFrames>
            <DoubleAnimation Storyboard.TargetProperty="Opacity" From="0" To="1" Duration="0:0:0.5" />
          </Storyboard>
        </BeginStoryboard>
      </DataTrigger.EnterActions>
      <DataTrigger.ExitActions>
        <BeginStoryboard>
          <Storyboard>
            <DoubleAnimation Storyboard.TargetProperty="Opacity" From="1" To="0" Duration="0:0:0.5" />
            <ObjectAnimationUsingKeyFrames Storyboard.TargetProperty="Visibility">
              <DiscreteObjectKeyFrame KeyTime="0:0:0.5" Value="{x:Static Visibility.Collapsed}" />
            </ObjectAnimationUsingKeyFrames>
          </Storyboard>
        </BeginStoryboard>
      </DataTrigger.ExitActions>
    </DataTrigger>
  </Style.Triggers>
</Style>

Hi @GF-Huang I apologize for the long delay, I will get back to you as soon as I can 👍

@GF-Huang aahh, I understand what you want, and this has been a feature I've not yet implemented. I've wanted to implement a property such as xf:Animations.HideOnFaded="True", which when an element reaches an Opacity of 0 (and vice-vrsa), I would essentially set IsHitTestVisible="False" and maybe even set Visibility like you mention here. I hope I can eventually achieve it because there are some scenarios that it can be useful, and yours is one of them. I'm currently working on a version to bump the nuget packages for Uno.
