Set the value for Dynamically Created Dropdowns

Hi,

I am creating a set of controls on a tap over some button. It contains some editors and a drop down (combination of a label and image) each. When I click on the drop down label, it opens a popup, populates the drop down items. On tapping on any item, it will set that drop down label value to that selected value. I can do that with single drop down through the x:Name. But for the dynamically created blocks, I can not set the selected value at popup back to the drop down label. Please help.
