At first glance, it looks like your imgAddToCart_Click method is not
bound to the click event of the button. In VB.net, you would declare
the method:
protected sub imgAddToCart_Click(object sender, ImageClickEventArgs e)
handles imgAddToCart.Click
Notice the _handles imgAddToCart.Click_ after the method declaration.
I use the OnClick HTML attribute when I want the button to call some
client-side Javascript before firing the server-side Click event.
