Update content between tabs

Question

Hello i am using a tabbed app and I have a button in one tab, and I'm not sure how to do it that when the user presses it I want to update content in another tab. I tried experimenting with binding but I couldn't figure it out.

Hello,

Welcome to Microsoft Q&A!

You can simply use MessagingCenter, it is a publish-subscribe pattern, allowing message-based communication between components that are inconvenient to link by object and type references.

Send in Button Click event

   private void Button_Clicked(object sender, EventArgs e)  
   {  
        MessagingCenter.Send<object>(this, "Hi");  
   }  

Subscribe in another tab(page)

   public Page3()  
   {  
        InitializeComponent();   
        MessagingCenter.Subscribe<object>(this, "Hi", (o) => {   
                    //do something  
         });  
    }
