I am also facing the same issue , popover is not getting displayed over the modal.Can you help how you fixed your issue.
Here is sample code how I am launching the popover
<button id="marksButton" type="button"' +
'data-toggle="popover" data-placement="auto right" data-container="body" ' +
'data-content="' + kendo.htmlEncode(marks) + '"' +
'data-title="Marks" data-trigger="click" data-role-me="content-popover" > Marks</button>
This is working fine when we are calling this directly in the html page but while calling inside a modal popover is not coming at all.
Can you please help to fix this issue.
Thank you in Advance
