Try this instead:
Markup:
Create a placeholder DIV
to show the modal content within, like this:
<a data-target="#myModal" class="quick-btn" data-toggle="modal" href="/SystemSettings/NewUser.aspx">Click Me</a>
<div class="modal hide fade" id="myModal">
</div>
JavaScript:
Add the .aspx
page's content to an iframe
, like this:
$(document).ready(function() {
$('[data-toggle="modal"]').click(function(e) {
e.preventDefault();
var url = $(this).attr('href');
$(".modal-body").html('<iframe width="100%" height="100%" frameborder="0" scrolling="no" allowtransparency="true" src="'+url+'"></iframe>')
});
});
