Is there a way that I can put progressbar inside the List view cell? Xamarin Forms

I just learn how simple progress bar works. But I want to make a progress graph percent or some sort of progress status.

The problem is, I'm having a problem whenever I include the progressbar inside the list view cell. Is it possible that I can put the progressbar working inside the list view cell? Here's my code.

<ListView>
    <ListView.ItemTemplate>
      <DataTemplate>
        <ViewCell>
          <StackLayout Orientation="Vertical" Padding="10">

          <Grid>
            <Grid.RowDefinitions>
              <RowDefinition Height="*" />
              <RowDefinition Height="*" />
              <RowDefinition Height="*" />
            </Grid.RowDefinitions>

            <Grid.ColumnDefinitions>
              <ColumnDefinition Width="*" />
              <ColumnDefinition Width="*" />
            </Grid.ColumnDefinitions>

            <Label Text="Dummy Me" Grid.Row="0" Grid.Column="0" />
            <Label Text="Dummy Me2" Grid.Row="0" Grid.Column="1" />
          </Grid>
          <ProgressBar x:Name="myProgressStatus" Progress="0.2" HeightRequest="200" Width="150" />

          </StackLayout>
        </ViewCell>
      </DataTemplate>
    </ListView.ItemTemplate>
  </ListView>  

Here's my Progress behind the xaml.

    protected async override void OnAppearing()
    {
        base.OnAppearing();

        myProgressStatus.ProgressTo(.2, 250, Easing.Linear);
    }

While the error says,

The name 'myProgressStatus' does not exist in the current context   ...
