Christopher Pezza Convert a deduped List to a Select Options in apex
Ok so I am trying to create a Select List in Visualforce of a list that was just deDuped with this code below:
When I do this the public List<SelectOption> won't let me save i get this Error: "Expression must be a list type: SET<String>" The line is: "options.add" line
public with sharing class CustomerHealth{
Set<String> cmSet = new Set<String>();
public CustomerHealth() {
for(Customer_Health__c ch : [SELECT Customer_Success_Manager__c FROM Customer_Health__c WHERE Customer_Success_Manager__c <> ' ']){
cmSet.add(ch.Customer_Success_Manager__c);
}//END for
}//END public
public List<SelectOption> getCSMItems() {
List<SelectOption> csmoptions= new List<SelectOption>();
Decimal i;
for (i=0; i < cmSet.size(); i++) {
options.add(new SelectOption(cmSet[i], cmSet[i]));
}
return csmoptions;
}
}//END public with sharing
When I do this the public List<SelectOption> won't let me save i get this Error: "Expression must be a list type: SET<String>" The line is: "options.add" line
This is what im trying to output it in in visualforce:
Help please :)
<apex:selectList size="1" styleClass="btn btn-green btn-xs" value="{!CSMFilter}" onchange="RefreshTable1()">
<apex:selectOption value="{!cmSet}"></apex:selectOption>
</apex:selectList>

We Can't Use Set as array So We have to use List instead of Set or We have to itrate set values.
i.e,
Controller----
public with sharing class CustomerHealth { Public String CSMFilter {get ; set;} public Set<String> cmSet {get; set;} public CustomerHealth() { cmSet = new Set<String>(); for(Customer_Health__c ch : [SELECT Customer_Success_Manager__c FROM Customer_Health__c WHERE Customer_Success_Manager__c <> ' ']){ cmSet.add(ch.Customer_Success_Manager__c); }//END for }//END public public List<SelectOption> getCSMItems() { List<SelectOption> csmoptions= new List<SelectOption>(); for (String s : cmSet) { csmoptions.add(new SelectOption(s, s)); } return csmoptions; } }Vf Page---
<apex:page controller="CustomerHealth" > <apex:form > <apex:selectList size="1" styleClass="btn btn-green btn-xs" value="{!CSMFilter}" onchange="RefreshTable1()"> <apex:SelectOptions value="{!csmItems}"/> </apex:selectList> </apex:form> </apex:page>Change Select Options Value With csmItems
