In order to prevent the close action on a Kendo UI Mobile ModalView, you can execute preventDefault() in the close event of the widget, as shown in this example:
I have a few remarks about your setup:
1. Attaching click events with onclick, will not work reliably well in mobile device, please check the above example on how to attach a click handler that will work correctly on mobile touch devices.
2. $("#modalview-login").kendoMobileModalView("close"); - this is not the correct API way for closing the ModalWindow, please check the above example for the correct way of calling the close() method. Same is valid for the open() method as well.
I hope this information will be helpful.
