Partial Views question

Question

I am using some partial views in my app, just to keep code organized and also to reuse some views.
My partial views have a ViewModel as well, but I don't understand how to make data from the partial view available to the parent view.

For example:

ParentPage:

<ContentPage.Content>
    <views:PartialView1 />
    <views:PartialView2 />
</ContentPage.Content>

Can the ParentPage read data from PartialView1 or PartialView2?
Let's say that in PartialView1ViewModel I have a property public List<Post> Posts { get; set; } how can I read the value from ParentPageViewModel?

Hello,

Welcome to Microsoft Q&A!

The best way is to create a PartialView1ViewModel instance inside ParentPageViewModel , initial and populate data , then you can access the data inside ParentPageViewModel.

For example

   public class PartialView1ViewModel  
       {  
           public List<Post> Posts { get; set; }  
       }  

       public class ParentPageViewModel  
       {      
           PartialView1ViewModel model;  
           public ParentPageViewModel()  
           {  
               model = new PartialView1ViewModel { Posts = new List<Post>() };  
           }  


           void somewhereYouWantToAccess()  
           {  
               var list = model.Posts;  
           }  

       }  

Thank you.
