    <p>Another better option, roll your own PageStatePersister. Here's mine, heavily inspired by <a href="http://aspalliance.com/72" rel="noreferrer">http://aspalliance.com/72</a>:</p> <pre><code>using System.Web.UI; ... in your page class: PageStatePersister pageStatePersister; protected override PageStatePersister PageStatePersister { get { // Unlike as exemplified in the MSDN docs, we cannot simply return a new PageStatePersister // every call to this property, as it causes problems return pageStatePersister ?? (pageStatePersister = new BetterSessionPageStatePersister(this)); } } ... in your BetterSessionPageStatePersister.cs: /// &lt;summary&gt; /// This class allows the viewstate to be kept server-side, so that postbacks are as small as possible. /// It is similar to the built-in 'SessionPageStatePersister', but it yields smaller postbacks, /// because the SessionPageStatePersister still leaves some viewstate (possibly it leaves the controlstate) /// in the postback. /// &lt;/summary&gt; class BetterSessionPageStatePersister : PageStatePersister { public BetterSessionPageStatePersister(Page page) : base(page) { } const string ViewStateFieldName = "__VIEWSTATEKEY"; const string ViewStateKeyPrefix = "ViewState_"; const string RecentViewStateQueue = "ViewStateQueue"; const int RecentViewStateQueueMaxLength = 5; public override void Load() { // The cache key for this viewstate is stored in a hidden field, so grab it string viewStateKey = Page.Request.Form[ViewStateFieldName] as string; // Grab the viewstate data using the key to look it up if (viewStateKey != null) { Pair p = (Pair)Page.Session[viewStateKey]; ViewState = p.First; ControlState = p.Second; } } public override void Save() { // Give this viewstate a random key string viewStateKey = ViewStateKeyPrefix + Guid.NewGuid().ToString(); // Store the view and control state Page.Session[viewStateKey] = new Pair(ViewState, ControlState); // Store the viewstate's key in a hidden field, so on postback we can grab it from the cache Page.ClientScript.RegisterHiddenField(ViewStateFieldName, viewStateKey); // Some tidying up: keep track of the X most recent viewstates for this user, and remove old ones var recent = Page.Session[RecentViewStateQueue] as Queue&lt;string&gt;; if (recent == null) Page.Session[RecentViewStateQueue] = recent = new Queue&lt;string&gt;(); recent.Enqueue(viewStateKey); // Add this new one so it'll get removed later while (recent.Count &gt; RecentViewStateQueueMaxLength) // If we've got lots in the queue, remove the old ones Page.Session.Remove(recent.Dequeue()); } } </code></pre>

    3. COThis code only allows X tabs to be open at the same time, in this example, opening 6 tabs will remove the viewstate for the first tab.

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).
