Answer 1

private class TabSource 
{ 
    private string dataForTab = string.empty; 
    public string DataForTab { get { return dataForTab; } } 
    public void GetRealData() 
    { 
     dataForTab = "Real Data"; 
     NotifyPropertyChanged("DataForTab"); 
    } 
} 


public Button_Click_2(...) 
{ 
    MyTabSource.GetRealData();  
}
