Property Exists vs Property Not Set

I need a way to tell whether a page does not have a particular property defined versus having the property defined but no value set. How can I do this?

pseudo code for what I want to accomplish:

if(CurrentPage contains a property called "theProperty")
if(CurrentPage["theProperty"] != null)
do something...

I only want to apply the logic in the second "if" statement if the page has a property called "theProperty" defined.

Thanks!

If a property is not set it will not be saved in the database. But I guess you could load the actual pagetype definitions to check if your property exists.

Check out the PageType class.

There is a function in the property class:

CurrentPage.Property.ExistsLocally("MyProp")
