FindName searches across siblings!

03-25-2008 7:44 PM |

So I have some Xaml that looks like the following:

<StackPanel x:Name="Parent">

<StackPanel x:Name="Child1" />

<StackPanel x:Name="Child2" />

</StackPanel>

In code behind I add a child to Child2 named "grandChild".  I then try to find "grandChild" under Child1 by Child1.FindName("grandChild").  You would think it would return null but instead it is actually returning the "grandChild" that is a child of Child2!  So it seems that the FindName function is working across siblings, which of course is not what is expected.

So as a test I moved Child2 outside the Parent thereby effectively making it a sibling of "Parent".  The same FindName above now returns a null as expected.
