Hello,​

Welcome to our Microsoft Q&A platform!

You could get the MenuItem via the sender, then get the BindingContext of the menuItem to retrive the data.

Check the code:

   void OnItemClicked(object sender, EventArgs e)  
   {  
       // The sender is the menuItem  
       MenuItem menuItem = sender as MenuItem;  
       var contextItem = menuItem.BindingContext as Employee;  
     
      DisplayAlert("Your Name is ",contextItem.Name,"Ok");  
   }
