Silverlight parent form passed value to ChildWindow

On the internet to find a lot of columns, some do not understand, some too troublesome.

Now there are two ways to be simple and practical, to share to everyone!

First: Use the constructor to pass a value

1. Create a new constructor for the child page

1   PublicChildwindowtest (stringtexts)2         {3           4 InitializeComponent ();5             //the value passed by the parent class .6              This. Text1.Text =texts;7         }8 9 //texts is the value passed from the parent page.

2. Parent Page object that creates a child page

1 // you need to pass a value in the ChildWindow constructor 2 New Childwindowtest ("ChildWindow Usage: Parent page, sub-page mutual value ");

3, the sub-page constructor parameter texts is "ChildWindow Usage: Parent page, sub-page mutual value"

The second type:

1. Define a method on the sub-page

1  Public void UPDATETEXT (string2        {3             tbname.text = Str; 4         }

2. Create a child Page object on the parent page

1 New Childwindowtest ();

3. How to invoke a child page when the child page is facing the parent page:

1 childwindow.updatetext ("ChildWindow Usage: Parent page, sub-page mutual value ");

In the method UpdateText (string Str) of the child page, you can manipulate the passed value.
