Login control in an ASP.NET AJAX toolkit PopupControlExtender with a close button--write by Laurent Kempé

I remember when I tried to implement a Login control in a ModalPopup with one of the early release of what was called at that time Atlas and is now called ASP.NET AJAX. I had lots of difficulties and now it works like a charm.

This time I would like to have a Login control in an ASP.NET AJAX PopupControlExtender from the ASP.NET AJAX Control Toolkit.

The implementation is really straight, a panel with a asp:Login in it:

<asp:Panel ID="loginPanel" runat="server" Style="display: none">
    <asp:Login ID="LoginCtrl" runat="server"
CssSelectorClass="THBLogin"
        FailureText="Identifiant incorrect ! Essayez ? nouveau..."
        LoginButtonText="S'identifier"
PasswordLabelText="Mot de Passe"
PasswordRequiredErrorMessage="Le mot de passe est requis."
        RememberMeText="Se souvenir de moi la prochaine fois."
TitleText="S'identifier"
        UserNameLabelText="Email"
UserNameRequiredErrorMessage="L'email est requis."
CreateUserText="S'enregistrer"
CreateUserUrl="/Register.aspx"
PasswordRecoveryText="Mot de passe oubli? ?"
PasswordRecoveryUrl="/PasswordRecovery.aspx" />
</asp:Panel>

Then you had the PopupControlExtender:

<ajaxToolkit:PopupControlExtender ID="PopEx" runat="server"
    TargetControlID="loginHyperLink"
    PopupControlID="loginPanel"           
    Position="Left" />

I also need a target control that will initiate the Popup display:

<asp:HyperLink ID="loginHyperLink" runat="server">S'identifier</asp:HyperLink>

Till now nothing really special.

Then I wanted to add a close button to this Popup, so I a added a div closeLoginPanel with an embedded link:

<asp:Panel ID="loginPanel" runat="server" Style="display: none">
    <div class="closeLoginPanel">
        <a title="Fermer">X</a>
    </div>
    <asp:Login ID="LoginCtrl" runat="server" 

This is not enough because I need to have the close action started when a user click on the link (X). I first looked at the javascript of the PopupControlExtender and saw that it handles the onclik of the body element so I added

<a onclick="document.body.click(); return false;" title="Fermer">X</a>

This was working fine on Internet Explorer 7 but was raising an error on FireFox 2. Looking in more detail in the javascript I finally changed my code to:

<a onclick="AjaxControlToolkit.PopupControlBehavior.__VisiblePopup.hidePopup(); return false;" title="Fermer">X</a>

This is working on both Internet Explorer and FireFox 2.

Here is the css I used:

.closeLoginPanel
{
    font-family: Verdana, Helvetica, Arial, sans-serif;
    line-height: 17px;
    font-size: 11px;
    font-weight: bold;

    position: absolute;
    top:8px;
    right: 10px;
}

.closeLoginPanel a
{
    background-color: #6699CC;
    cursor: pointer;
    color: #FFFFFF;
    text-align: center;
    text-decoration: none;
    padding: 5px;
}

Here is the result:
