I need an update panel to update ddl after div becomes visible, I have a code as shown below but I can not remember (or find on the net)
According to your description, I couldn’t understand your requirement clearly.
You say that when the div becomes visible="true/false", then update your dropdownlist, but in your code, there are 2 divs, which one do you mean?
And what do you want to do to change the value of visible?
And in your code behind, there are 4 methods, I don't see where to call them.
Please describe your requirements in detail and post your complete code.
