如何设置ControlTemplate的子项的属性？

Question

I have ControlTemplate control, it's x:Name="MyControlTemplate" . It contains ListBox it's x:Name="MyListBox" .

Then in my XAML code I have:

<ContentControl Template="{StaticResource MyControlTemplate}" x:Name="MyContentControl"/>

I need to assign ItemsSource property to MyListBox in C# code of MainPage.xaml.cs .

How can I do it?

First you need to find the list box then just set the property.

ListBox listBox = (ListBox) MyContentControl.Template.FindName("MyListBox", MyContentControl);
listBox.ItemsSource = new List<string>() { "1", "2", "3" };
