I am working on an auction site which is in 3-Tier architecture.There is one server side method in AuctionHub.cs file as follows:

C#

public BAL.LiveAuctionBAL AuctionBid(string Lot_Id, string InputAmt, string vendorid, string V_AuctionID, string AddModBy, string OpenBidAmt, string Decrementbid, string LastBidAmount, string auctionEndTimer)
{
BAL.LiveAuctionBAL BAL = new BAL.LiveAuctionBAL();
string result = "";
string msg = "", message = "";
try
{
BAL.Auction_Id = Convert.ToInt32(V_AuctionID);
BAL.Lot_Id = Convert.ToInt32(Lot_Id);
BAL.Vendor_Id = Convert.ToInt32(vendorid);
BAL.Bid_Amount = Convert.ToDouble(InputAmt);
if (auctionEndTimer != "")
{
BAL.AuctionEndTimer = DateTime.Parse(auctionEndTimer.ToString());
}
else
{
BAL.AuctionEndTimer = Convert.ToDateTime("01/01/1900");
}

BAL.AddMod_By = AddModBy;

result = BAL.AddAuctionBid();

if (result != "")
{
msg = result;
this.Clients.All.bidUpdated(result);
}
}
catch
{

}
return BAL;
}
}

Now I am trying to call this method at client side as follows:

JavaScript

var chat = $.connection.auctionhub;
$(function () {
$.connection.hub.start().done(function () {
chat.server.auctionbid(Lot_Id, InputAmt, vendorid, V_AuctionID, AddModBy, OpenBidAmt, Decrementbid, LastBidAmount, auctionEndTimer);
 });
});

but the method is not getting called at client side...Can anyone help me please? its urgent.

It's only the first char that changes to lowercase:

JavaScript

var chat = $.connection.auctionhub;
$(function () 
  {
      $.connection.hub.start().done(function () {
          chat.server.auctionBid(
                Lot_Id, 
                InputAmt, 
                vendorid, 
                V_AuctionID, 
                AddModBy, 
                OpenBidAmt, 
                Decrementbid, 
                LastBidAmount, 
                auctionEndTimer
         ).done(function(returnVal)
                  {
                     //only if you need this
                  });
     });
  });

You can check the browser resources. There will be a subfolder called signalr that contains hub.js. This is the clientside code for interacting with the server.
