User Control displayed with a loop

[Pi]

Hi guys,

I have created a web user control that has 2 datagrids on a panel. What
I need to do is to go through a collection and depending on the count
of the collection, display my control with the datagrids populated/
bound with the collections.

Although the code doesn't give me any errors, the control is not being
displayed on the webpage. I am adding the code here for both my web
control and the page that uses it. I hope someone can help me in
figuring this out.
