***************************** STEPS TO FOLLOW DURING CREATION OF 'UserControl' *******************************

STEP 1:
Any UserControl that we create in this project solution should be of type 'IVMAUserControl'. So, we have to Implement all properties of IVMAUserControl.

STEP 2:
Copy and paste below Code and do necessary changes wherever we have marked ---->(%000%)


START CODE:


    #region Page Initializer

		--------------->(%000%) /* Change Name to Corresponding 'Page' or 'UserControl' */
        public CONSTRUCTOR() 
        {
            this.InitializeComponent();			
            this.DataContextChanged += ConversationDetailedPage_DataContextChanged;
            InitilizeLocalComponent();           
        }

        private void ConversationDetailedPage_DataContextChanged(FrameworkElement sender, DataContextChangedEventArgs args)
        {
            this.OnDataContextChanged(args.NewValue);
        }

        #endregion

        #region IVMAPage
        public void InitilizeLocalComponent()
        {

        }
        
        public void OnDataContextChanged(object datacontext) 
        {

               1. You could assign any ViewModel of type IViewModel any number of times
