Answer 1

you can have access to that textbox in the event "TextChanged" like this

    private void NomeTextBox_TextChanged(object sender, TextChangedEventArgs e)
{
    var textbox = (TextBox)sender;

    var obj = textbox.DataContext;
}

Here you get access to the control and the object inside of it.

u can make it also in the selection changed event of the item control to get the data context of your custom object LISTACLIENTE.
