    <p>In this instance you have to use cookieless sessions - in web.config in system.web</p> <pre><code>&lt;sessionState mode="InProc" timeout="20" cookieless="UseUri" /&gt; </code></pre> <p>what this does is insert a session id into the url so you get something like, www.host.com/(abc15284dndhjkdm)/app.aspx. thisis then unique per tab and so the user can have uniqie session per tab.</p> <p>Edit: - here is the code for the aspx pages i show at web3.adprs.net/test/test1.aspx i mention below</p> <p>Test1.aspx</p> <pre><code>&lt;%@ Page Language="vb" AutoEventWireup="false" CodeBehind="test1.aspx.vb" Inherits="WebApplication4.test1" %&gt; &lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; Enter User &lt;asp:TextBox ID="user" runat="server"&gt;&lt;/asp:TextBox&gt; &lt;asp:Button ID="go" runat="server" Text="Go" /&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt;&lt;/html&gt; </code></pre> <p>Test1.aspx.vb</p> <pre><code>Public Class test1 Inherits System.Web.UI.Page Private Sub go_Click(sender As Object, e As System.EventArgs) Handles go.Click Session("user") = user.Text Response.Redirect("test2.aspx") End Sub End Class </code></pre> <p>Test2.aspx</p> <pre><code>&lt;!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"&gt; &lt;html xmlns="http://www.w3.org/1999/xhtml"&gt; &lt;head runat="server"&gt; &lt;title&gt;&lt;/title&gt; &lt;/head&gt; &lt;body&gt; &lt;form id="form1" runat="server"&gt; &lt;div&gt; Your user from session is &lt;%=Session("user").ToString%&gt; &lt;/div&gt; &lt;/form&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>web.config</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;configuration&gt; &lt;system.web&gt; &lt;compilation debug="true" strict="false" explicit="true" targetFramework="4.0" /&gt; &lt;sessionState mode="InProc" timeout="20" cookieless="UseUri" /&gt; &lt;/system.web&gt; &lt;system.webServer&gt; &lt;modules runAllManagedModulesForAllRequests="true"/&gt; &lt;/system.webServer&gt; &lt;/configuration&gt; </code></pre> <p>HTH</p>

    2. CODid you make the web.config change - this is standard asp.net functionality i have many sites that are set up with thousands of users many of whom will log in on seperate tabs and it works ok. If you open a new tab to www.site.com/main.aspx, it will see you dont have a session token in the url and send a redirect to www.site.com/{uniqueid}/main.aspx. Maybe you are copying and pasting the full url into the new tab, you should only go to the url without the token.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
