using microsoft.aspnet.signalr; using system; using system.collections.generic; using system.linq; using system.web; using system.web.ui.webcontrols; namespace signalr { public class seekerhub : hub { public void sayhellotoall(string message) { clients.all.sayhellotome(message); var callingclient = context.connectionid; } } } thanks in advance can give me.
the problem trying call client method sayhellotome client.
replace line of code:
helloconnection.client.sayhellotome = function (message) { alert(message); }; with this:
helloconnection.on('sayhellotome ', function(message) { alert(message); }); this way have handler on client side listening server side trigger being sayhellotome
