I have a image inside a ViewCell, I've added a TapGestureRecognizer to the image, now when the user clicks the image I want to Access the data from data ViewCell

How can I do that?

    You can create custom ViewCell and use it as you wish. your first page should be like this

    and your MyViewCell Class Should be Inherit ViewCell in both cs and Xaml Page.In your CustomViewCell you have full Controll in all Controls.

    EDIT: See better solution next post. But leaving this post as is as some might like the idea of having a view model for the view cell.

    I think easiest is to have a view model for your ViewCell and then use Command instead of Tapped to handle the image click. With Command you can pass a parameter.


                Command="{Binding ImageTapCommand}"
                CommandParameter="{Binding .}"/>

    Binding . passes the current item in the list, the ViewCell's view model, whose image was tapped.

    In the ViewCellViewModel:

    public ICommand ImageTapCommand { get; private set; }
    public ViewCellViewModel()
            ImageTapCommand = new Command(ImageTapped);
    void ImageTapped(object obj)
            var item = obj as ViewCellViewModel;
            // obj is this ViewCellViewModel instance
            // so in reality you do not even need to use the obj variable
            // as you can just access the properties of the ViewCellViewModel
            // directly.

    I've attached a sample with this in action, modified from this sample.
