How can we apply a filter in quick consumer application in RFA.net to get only Ask/Bid Prices.

Sample code:

FieldList fieldList = payload as FieldList;
///Console.WriteLine("FieldList's entry count: " + fieldList.StandardDataCount);
short fieldId;
foreach (FieldEntry fieldEntry in fieldList)
{
fieldId = fieldEntry.FieldID;
try
{
RDMFidDef fidDef = rdmFieldDictionary.GetFidDef(fieldId);

}

There are two ways to do this:

a. In the foreach iterator, compare each fieldId to the one you desire (BID, ASK) and ignore others.

b. Send a view request, whereby only the fids that are requested are returned in the update messages. This capability is a licenseable feature, and has to be enabled on your ADS. Look at StarterConsumer_BatchView example for details.

Currently i am using first approach only. I am filtering out based on the Field names like BID or ASK but i am filtering after information coming from server.

Can i do the filtering before sending the request like based on Field ID (22 or 25) for Ask or BID? Will this number be changed or it will remain same?

This is the View feature, presented in the option (b) above.
