Retrieve Custom Setting values

Question

Can we get custom setting field values in visualforce component without using controller

Answer 1

For a List Custom Setting, you can't directly access the settings directly by a formula. For a hierarchy setting, you can use $Setup.CustomSettingName__c.FieldName__c. See $Setup for more details on how this works.

If you want to insert/update/delete List settings, however, you can use remote objects. I suggest you read the manual for more information. Note that this only allows you to access the settings by JavaScript; you won't be able to use them in formulas.
