Part 3 – Sign Out/Sign in as a Different User
A project I am working on called for a custom implementation of the SharePoint Welcome menu control. The replacement control needed to provide the following:
- Implement the look and behaviors that the designers created.
- Exclude some default SharePoint menu items (such as My Regional Settings).
- Reuse some existing SharePoint menu items (such as Sign Out/Sign in as a Different User).
- Allow for the addition of other custom menu items in the future.
- Display thumbnail of the user’s profile picture.
I had to create a control that looked and behaved like the following:
The designers came up with some clean, semantic markup married with some jquery, for me to start from:
<div class="header">
<img class="header-logo" src="/images/header_logo.png" alt="" width="169" height="78" />
<div class="header-bar">
<div class="profile_menu">
<a href="#" class="profile_btn">
<span class="image"><img src="" style="width:20px;height:20px" /></span>
<span class="name">John Doe</span>
<span class="arrow"></span>
</a>
<div class="profile_dropdown">
<div class="dropdown_bkgrd">
<ul>
<li>Edit Profile</li>
<li>My Site</li>
<li>Log Out</li>
<li>Sign in as a Different User</li>
</ul>
</div>
</div>
</div>
</div>
</div>
This is part 3 of a three part series.
- Part 1 – Overview, Profile Picture, and User Name
- Part 2 – Edit Profile and My Site links
- Part 3 – Sign Out/Sign in as a Different User
Building the Sign Out Links
The Sign Out and Sign in as a Different User menu items are rendered by the PersonalActions control, in two methods (from Reflector):
private void SetLoginAsDifferentUserMenuItemGoToPageUrl()
{
MenuItemTemplate menuItem = base.GetMenuItem("ID_LoginAsDifferentUser");
if (menuItem != null)
{
if (SPSecurity.AuthenticationMode == AuthenticationMode.None)
{
menuItem.Visible = false;
}
else
{
string serverRelativeUrlFromUrl = this.Web.GetServerRelativeUrlFromUrl("_layouts/closeConnection.aspx?loginasanotheruser=true");
menuItem.ClientOnClickScript = "javascript:LoginAsAnother('" + SPHttpUtility.EcmaScriptStringLiteralEncode(serverRelativeUrlFromUrl) + "', 0)";
}
}
}
private void SetSignOutMenuItemGoToPageUrl()
{
MenuItemTemplate menuItem = base.GetMenuItem("ID_Logout");
if (menuItem != null)
{
if (SPSecurity.AuthenticationMode == AuthenticationMode.None)
{
menuItem.Visible = false;
}
else
{
menuItem.ClientOnClickNavigateUrl = this.Web.GetServerRelativeUrlFromUrl("_layouts/SignOut.aspx");
}
}
}
The “Sign Out” link points to “_layouts/SignOut.aspx”, and “Sign in as a Different User” points to “_layouts/closeConnection.aspx”.
To leverage this, I again adjusted the ASCX markup to include some PlaceHolder and LinkButton controls:
<div class="profile_dropdown">
<asp:PlaceHolder ID="placeHolderUserID" runat="server"></asp:PlaceHolder>
<div class="dropdown_bkgrd">
<ul>
<asp:PlaceHolder ID="placeHolderEditProfile" runat="server"><li><asp:LinkButton ID="linkButtonEditProfile" runat="server" EnableViewState="false" Text="Edit Profile"></asp:LinkButton></li></asp:PlaceHolder>
<asp:PlaceHolder ID="placeHolderMySite" runat="server"><li><asp:LinkButton ID="linkButtonMySite" runat="server" EnableViewState="false" Text="My Site"></asp:LinkButton></li></asp:PlaceHolder>
<li><asp:LinkButton ID="linkButtonLogOut" runat="server" EnableViewState="false" Text="Sign Out"></asp:LinkButton></li>
<li><asp:LinkButton ID="linkButtonLoginAsDifferentUser" runat="server" EnableViewState="false" Text="Sign in as a Different User"></asp:LinkButton></li>
</ul>
</div>
</div>
And then here is some code-behind that re-creates the output from the PersonalActions control:
// Login as another user
string loginAsAnotherUserUrl = this.ResolveClientUrl("~/_layouts/closeConnection.aspx?loginasanotheruser=true");
linkButtonLoginAsDifferentUser.OnClientClick = string.Format("LoginAsAnother('{0}', 0);return false;", SPHttpUtility.EcmaScriptStringLiteralEncode(loginAsAnotherUserUrl));
// Sign out
string signOutUrl = this.ResolveClientUrl("~/_layouts/SignOut.aspx");
linkButtonLogOut.OnClientClick = "GoToPage('" + SPHttpUtility.EcmaScriptStringLiteralEncode(signOutUrl) + "');return false;";
Summary
In this post, we deconstructed the PersonalActions control further to re-create the Sign Out and Sign in as a Different User menu items.

Hopefully you find this useful, and can take it further if need be. Leave comments if you have any questions.
very well done, i would have like to seen the css that goes along with this.
Nice work. However I want to know how you make the div to be a dropdown. Thanks.
