Multiple modal popup extenders in update panel

Question

I have two modal popup extenders inside an update panel. Problem is when I call the show method of any modal popup both popups are shown.

Please let me know how can we solve this? thanks in advance.

My guess without seeing any code is you have them bound to the same control.

<asp:button id="SAME_ID" runat="server" />

<ajaxtoolkit:modalpopupextender 
    id="ModalPopupExtender" 
    runat="server"    
    targetcontrolid="SAME_ID"> 
</ajaxtoolkit:modalpopupextender> 

<ajaxtoolkit:modalpopupextender 
    id="ModalPopupExtender2" 
    runat="server"    
    targetcontrolid="SAME_ID"> 
</ajaxtoolkit:modalpopupextender>
