ModalPopupExtender has to use a panel to display as the modal popup frame.
This code:
<asp:scriptmanager id="ScriptManager1" runat="server" xmlns:asp="#unknown">
<asp:modalpopupextender cancelcontrolid="cancelLoginButton" id="loginModalPopuExtender" targetcontrolid="loginLinkButton" popupdraghandlecontrolid="PopupHeader" popupcontrolid="loginPanel" runat="server" xmlns:asp="#unknown">
<asp:panel style="display:none;" runat="server" id="loginPanel" xmlns:asp="#unknown">
      <div id="PopupHeader" class="modalPopup-header">Login</div>
         <table class="modalPopup-Content">
               <td style="width:50px;">
                  <asp:label id="Label1" runat="server" text="Email"></asp:label>
               <td style="width:200px;">
                        <asp:textbox id="emailTextBox" style="width:200px;" runat="server"></asp:textbox>
                   <asp:label id="Label2" runat="server" text="Passwort"></asp:label>
                   <asp:textbox id="passwordTextBox" style="width:200px;" runat="server" textmode="Password"></asp:textbox>
             <tr class="clear hideSkiplink">
                   <asp:button id="cancelLoginButton" runat="server" text="Abbrechen" cssclass="modalPopup-button" />
                <td style="text-align:right;">
                   <asp:button id="loginButton" runat="server" text="Login">
                            onclick="loginButton_Click" cssclass="modalPopup-button"/>

Looks like this on My Page[^]. To expand the popup, click on "Login" in the top right corner.
Feel free to view the page source, it might help you a bit...
