Need to include Zoom option in GanttView

[kanna]

Hi,
I am using GanttView for Silverlight and i am using collection to Bind the data(not in MVMM method in online example).
Please let me know how to include the Zoom option to the collection and also i want a suggestion to add the dependency for the below code (binding data to Collection).

Please find my code as below.
Regards,
Kannan
