2 content holders

Hi Sam,

Two solution for this:

1. use the findcontorl method to find out the contorl,and then register the control as a trigger by calling theRegisterAsyncPostBackControl(Control) method, and then refreshe theUpdatePanel control programmatically by calling theUpdate() method.

2.hide a button out of the placeholders, and set it to be a trigger of the updatepanel, then you can access to the button by using "document.getElementById('Button1')" in content placeholdes.
