Listbox is inaccessible due to its protection level Error in Windows Phone 8.1

I'm trying to add some text to a listBox in a form, from another form, but I get red underlines in the code that should add to the listBox. Isn't it possible to pass data to a form in a class from another class that I'm trying to do? I'm using VisualStudio 2013

I have this code I'm using in the MainForm class:

    // Local object of SearchResultForm
    SearchResultForm frmSearchResult = new SearchResultForm();
    frmSearchResult.Show();
    frmSearchResult.listBox.IsEnabled == false;

Error message: inaccessible due to its protected level

Add a Parameter To your class SearchResultForm class here my class is showvideolbx 

      public class showvideolbx
      {
         public ListBox SVListBox { get; set; }
      }

Assign ListBox Id to Class Parameter

     showvideolbx lbbox = new showvideolbx();
        lbbox.SVListBox = lbxSongsList;

Then Now You call the Create class and then ListBox Parameter as

     showvideolbx svlbox;
     if (svlbox.SVListBox.IsEnabled == false)
                svlbox.SVListBox.IsEnabled = true;

It will Work please try once.

Looks like your listBox is a private member of SearchResultForm; that means it's not accessible from outside the SearchResultForm class. You can make make the listBox variable public or internal, but a better way do to it is to create a mutator method in the SearchResultForm class something like: 

public void AddItemToListBox(string text) 
{
    listBox.Items.Add(text);
}

and then from your main form you will do: 

  // Local object of SearchResultForm
SearchResultForm frmSearchResult = new SearchResultForm();
frmSearchResult.Show();
frmSearchResult.AddItemToListBox("test");

This way you can update the listBox without exposing your SearchResultForm class implementation details.
