Element already child of other element error in Silverlight User Control

问题

I've placed some UIElements in a row of the grid at different column positions, now I have a + button if I click on that a new row containing same UIElements should be added below the first row. but it gives me error like "Element is already child of other element".

How can i get rid of this error. I need to add an duplicate copy(new reference) of the control below it in the new row. how can i do it? Any help would be appreciated....

Thanks, Gk Prajapati
