Hello,
I have a custom C# aspx page that was created to be used inside of SharePoint 2010. It uses several people-picker controls.
<SharePoint:PeopleEditorid="peopleEditor"runat="server"AutoPostBack="true"CssClass="ms-usereditor"></SharePoint:PeopleEditor>
It worked great in 2010. But in SharePoint 2013 when I click on the browse icon nothing pops up. So I found this:
<SharePoint:ScriptLinkname="clienttemplates.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="clientforms.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="clientpeoplepicker.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="autofill.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="sp.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="sp.runtime.js"runat="server"LoadAfterUI="true"Localizable="false"/><SharePoint:ScriptLinkname="sp.core.js"runat="server"LoadAfterUI="true"Localizable="false"/>
Now when I click on the browse icon this is what appears: A white blank pop up window. And the actual people picker popup. I can keep clicking on the browse icon and it will keep adding more popups.
I must be missing some kind of reference. It obviously is not displaying correctly, Any ideas?
Even the ClientPeoplePicker doesn't display correctly:
<SharePoint:ClientPeoplePickerrunat="server"ID="PeoplePickerControlName"Required="true"ValidationEnabled="true"InitialHelpText="text"VisibleSuggestions="3"Rows="1"AllowMultipleEntities="false"CssClass="ms-long ms-spellcheck-true"/>
I should add when I create a sharepoint page and add an iframe with the source being the aspx page. The 2010 people picker works. The ClientPeoplePicker still has display issues.

Can you help me please ?
Best regards
