How to open navigation Page in Listview local:view ?

<DataTemplate> <StackLayout HorizontalOptions="FillAndExpand" BackgroundColor="White"> <local:NewListView/> </StackLayout> </DataTemplate>
In NewListView.xmal.cs
<Image Grid.Column="13" Source="Reply_UnChecked.png"> <Image.GestureRecognizers> <TapGestureRecognizer Tapped="OnClickReply" NumberOfTapsRequired="1" /> </Image.GestureRecognizers> </Image>
In NewListView.cs
private void OnClickReply(object sender, EventArgs e) { var page = new ReplyPage(); Navigation.PushAsync(page); System.Diagnostics.Debug.WriteLine("Replay Page Open"); }
when i tapped OnClickReply the Debug was showed but the page did not create and open

I already tried await navigation.pushasync but also did not open new page.

I think the local:??? is in listview, so the navigation.pushasync is not work.

How can i create and open the new page when upper case?
