Ich habe Asp. NET SignalR verwendet und meine Web-Anwendung-Index-Seite funktionierte gut mit SignalR, aber als ich begann, Detailseite mit dieser Push-Benachrichtigungen System habe ich Fehler - SignalR ruft die Methode meines Clients nicht auf der Detailseite auf.ASP.Net SignalR nicht Client-Methode
Hier ist meine Details Seite Code Rasierer:
<h2>last bidders</h2>
<table class="table-info" style="width: 500px;">

<th>bidder</th>
<th>price</th>
<th>time</th>
<th>state</th>
</thead>
@for (int i = 0; i < 10; i++)
{
if (i < ViewBag.count) // Bidder exists
{

<td id="@Html.Raw("price" + i)">@ViewBag.prices[i]</td>
<td id="@Html.Raw("time" + i)">@ViewBag.times[i]</td>

else // No bidder - fill with blank

Hier ist meine Serverlogik. Ich verwende MyHub.cs als Hub-Klasse und Registry als Timer. Ich habe Code der Datenbankzugriffe und einige Berechnungen gereinigt, weil dieser Teil kein Problem hat, und ich wollte 350 Zeilen Code vermeiden, also habe ich gerade wichtigen Code in diesen SignalR-Interaktionen gelassen.
Ich habe Probleme mit Clients.All.auctionDetailsUpdate (...), während der Anwendung Webdebuggen es ist alles in Ordnung, und andere Verfahren SignalR Methoden sagt funktioniert, aber ich erhalte keine Benachrichtigung von meinen Angaben Seite angegeben in auctionDetailsUdate() -Methode wie es aus irgendeinem Grund hat Hub es nicht aufgerufen.
