I am trying to get a modal popup to display on an onblur event, but I keep getting a "'null' or is null or not an object" js error.
I have seen many examples using
var _popup;
_popup = $find('MPE');
_popup._show();
//And
$find('MPE')._show();
//And
$object('MPE')._show()
But none of them work. I just need to fire the Modal Popup on the client side...
Code for the Modal Popup:
<cc1:ModalPopupExtender ID="MPE" runat="server"
TargetControlID="TestButton"
PopupControlID="pnlWeightMessage"
BackgroundCssClass="modalBackground"
DropShadow="true"
OkControlID="BacktoForm"
/>
Thanks...
