TopContainer Property always Null

[Adam]

Hi, I am trying to write a behavior for a radcarousel panel such that when the top most item gets a MouseEnter event a state is activated.  However, the TopContainer property always comes up as null.  Is this because the TopContainer property is not set at this point?  Below is the line of code I am running.

this.AssociatedObject.TopContainer.MouseEnter += new MouseEventHandler(TopContainer_MouseEnter);

Thanks,

Hi Adam,

The null result is caused by the fact that the TopContainer is not yet realized. I am sending you a sample project illustrating a slightly different approach for achieving the required behavior - you need to subscribe to the TopContainerChanged event first and only then to invoke the MouseEnter and MouseLeave events. Thus you will ensure that the TopContainer will be available.
 

All the best,

Maya,

I suspected that was the case but didn't know how to get it to realize, thank you very much!
