Depending on how your data looks like, you probably get a data object to each button that contains the text. You can find that object in the buttons data context.

    private void calender_btn_Click(object sender, RoutedEventArgs e)
    {
        var dataObject = ((Button)sender).DataContext;
    }

If you are using ItemsSource you can get the selected value by binding to ListView SelectedItem (SelectedValue in some cases).

SelectedItem="{Binding SelectedData, Mode=TwoWay}"

Assuming that you have SelectedData property in your DataContext with same type as your data in the shown collection.

Google for MVVM
