 Now just you need  to  ; 

 ; ; ; 1-Replace the ownerclass name with your custom control name and just after the "typeof(ownerclass)" there is "new propertyMetadata(0)" replace it with null.

 ; ; ; 2- Change the return type of this property according to the control

Here is the proper dependency property  after changing  in balck ractangle as showing in the below picture:
