How to use Apex Repeat with Set Collection in Salesforce?
My Controller returns a list of strings in a SET variable to Visualforce page. I want to use an apex repeat to iterate over the SET collection but when I save the Visualforce page, It gives me an error. Is that we cannot use SET in apex:repeat in Salesforce?

You can definitely use a Set in a repeat.
In the Controller. The property and initializing it in the Constructor, for example’s sake:
public with sharing class TestController {
public Set<String> aset { get; set; }public TestController () {
aset = new Set<String>{‘a’,’b’,’c’};
}
}The Visualforce snippet:
<apex:repeat value=”{!aset}” var=”a”>
<apex:outputText value=”{!a}”/><br/>
</apex:repeat>
