Rifleman Displaying Return Values of Functions in SelectList
In my controller, I have this function, which calls a utility function to get all subordinate users to the currently logged in user:
public string getUsers() {
Set<Id> userlist = new Set<Id>();
userlist.add(UserInfo.getUserId());
userlist.addAll(RoleUtils.getRoleSubordinateUsers(UserInfo.getUserId()));
String retValue = ':All;';
Integer iCount = 0;
for (User usr: [select Name from User where Id in :userlist and isActive = true and Employee_Group__c like '%Sales%' order by Name]) {
retValue += usr.Name + ':' + usr.Name;
iCount++;
if (iCount < userlist.size()) {
retValue += ';';
}
}
return retValue;
}
How can I display the retValue, which is the list of users, in a SelectList on my VFPage? I imagine this is a fairly easy answer, but I just got handed a project and I've just started learning VF. Thanks for your help!
List<SelectOption> listOptions = new List<SelectOption>();
listOptions.add(new SelectOption('','--None--'));
List<String> strList = new List<String>();
strList = retValue.split(';');
for(String str : strList){
listOptions.add(new SelectOption(str,str));
}
VF Page
<apex:selectList id="selected_list" size="1" style="width:250px">
<apex:selectOptions value="{!listOptions}">
</apex:selectOptions>
</apex:selectList>

List<SelectOption> listOptions = new List<SelectOption>();
listOptions.add(new SelectOption('','--None--'));
List<String> strList = new List<String>();
strList = retValue.split(';');
for(String str : strList){
listOptions.add(new SelectOption(str,str));
}
And how would I call getUsers() to actually get the retValue?
You dont need to call getUsers(). Make retValue as a public variable and add the above code after retValue is populated.
public String retValue = ':All;';
public string getUsers() {
Set<Id> userlist = new Set<Id>();
userlist.add(UserInfo.getUserId());
userlist.addAll(RoleUtils.getRoleSubordinateUsers(UserInfo.getUserId()));
Integer iCount = 0;
for (User usr: [select Name from User where Id in :userlist and isActive = true and Employee_Group__c like '%Sales%' order by Name]) {
retValue += usr.Name + ':' + usr.Name;
iCount++;
if (iCount < userlist.size()) {
retValue += ';';
}
}
return retValue;
}
public List<SelectOption> getOptions(){
List<SelectOption> listOptions = new List<SelectOption>();
List<String> strList = new List<String>();
strList = retValue.split(';');
for(String str : strList){
listOptions.add(new SelectOption(str,str));
return listOptions;
}
VF Page
<apex:selectList id="selected_list" size="1" style="width:250px">
<apex:selectOptions value="{!Options}">
</apex:selectOptions>
</apex:selectList>
