I am using PeopleEditor in an application page which has master page file as follows:
DynamicMasterPageFile="~masterurl/default.master"
Code
<SharePoint:PeopleEditor ID="pp" MultiSelect="true" runat="server" BorderWidth="1px" Width="250px" SelectionSet="User" />
It works fine.
But when I use same PeopleEditor in an application page which has not master page then the page (that opens in browser) becomes very slow and I cannot even click inside PeopleEditor control to write anything as browser stops responding. I had to close the browser then. It happens only in IE.
Code
<form runat="server"><SharePoint:PeopleEditor ID="pp" MultiSelect="true" runat="server" BorderWidth="1px" Width="250px" SelectionSet="User" /></form>
Looks like it requires some SharePoint JS/CSS files to work properly which are available only when using master page in an application page.
Has anyone used PeopleEditor in an application page which has no master page?
