    <p>Using asp.net identity version 1.0.0-rc1 with Entity Framework 6.0.0-rc1 (the ones that come with Visual Studio 2013 RC).</p> <p>Trying to give users an opportunity to change their <code>UserName</code>. There seems to be no function for that under <code>AuthenticationIdentityManager</code>, so I change the data using EF (get User object for current user, change UserName and save changes).</p> <p>The problem is that authentication cookies remain unchanged, and the next request fails as there is no such user.</p> <p>With forms authentication in the past I used the following code to solve this.</p> <pre><code>var formsAuthCookie = Request.Cookies[FormsAuthentication.FormsCookieName]; var isPersistent = FormsAuthentication.Decrypt(formsAuthCookie.Value).IsPersistent; FormsAuthentication.SetAuthCookie(newUserName, isPersistent); </code></pre> <p>What should I do with asp.net identity to update the cookies?</p> <p><strong>UPDATE</strong></p> <p>The following code seems to update the authentication cookie.</p> <pre><code>var identity = new ClaimsIdentity(User.Identity); identity.RemoveClaim(identity.FindFirst(identity.NameClaimType)); identity.AddClaim(new Claim(identity.NameClaimType, newUserName)); AuthenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant (new ClaimsPrincipal(identity), new AuthenticationProperties {IsPersistent = false}); </code></pre> <p>The remaining problem is: how to extract <code>IsPersistent</code> value from current authentication cookie?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
