How to display public group users,when i had given group name in search bar need to display the users to particular group name in visualforce page? anybody help me.....

Answer 1

You can add the list of available groups using the below code change.

VF PAGE

<apex:selectList size="1">
    <apex:selectOptions value="{!Groups}"></apex:selectOptions>
</apex:selectList>

CONTROLLER

public List<SelectOption> getGroups(){
    List<SelectOption> ansprojoptions = new List<SelectOption>();    
    for(Group g: [select id ,name from group]){
        if(g.name!=null){
            ansprojoptions.add(new SelectOption(g.name,g.name));
        }
    }       
    return ansprojoptions ;
}

Use the value of {!Groups} in your code if you want to implement search from this.

Answer 2

I have built a Vf Page and custom controller to display the username using a wrapper which holds UserName and the GroupMember details if more userInformation is required you can modify the wrapper and the User SOQL query to fetch and map it accordingly in the wrapper.

VF PAGE

<apex:page controller="fetchUsers">
    <apex:form >
        <apex:inputText value="{!searchText}"/>
        <apex:commandButton value="Search Results" action="{!findUsers}" reRender="pb1"/>
        <apex:pageBlock id="pb1">
            <apex:pageBlockTable value="{!listUserGroupMemberWrapper}" var="lg" id="pbt1">
                <apex:column headerValue="Group" value="{!lg.grpMember.Group.name}"/>
                <apex:column headerValue="User" value="{!lg.UserName}"/>
            </apex:pageBlockTable>
        </apex:pageBlock>
    </apex:form>
</apex:page>

CONTROLLER

public with sharing class fetchUsers {

Public String searchText {get;set;}


public list<UserGroupMemberWrapper> listUserGroupMemberWrapper {get;set;}

public list<GroupMember> listGroupMember = new list<GroupMember>();
private list<Group> listGroup = new list<Group>();
private Map<Id,User> MapUser;
Private set<ID> groupIds = new set<ID>();
Private set<ID> UserIds= new set<ID>();

    public PageReference findUsers() {
        String SrcText='%'+searchText+'%';
        For(Group g : [select id from group where name like :SrcText]){
            groupIds.add(g.id);
        }
        listGroupMember = [Select id, Group.name,groupId,UserOrGroupId from GroupMember where groupId IN:groupIds]; 
        for(GroupMember gm : listGroupMember ){
            if(String.valueof(gm.UserOrGroupId).contains('005')){
                UserIds.add(gm.UserOrGroupId);
            }
        }
        MapUser = new Map<Id,User>([select id,name from user where Id IN:UserIds]);
        listUserGroupMemberWrapper = new List<UserGroupMemberWrapper>();
        for(GroupMember gm : listGroupMember ){
            if(String.valueof(gm.UserOrGroupId).contains('005')){
                UserGroupMemberWrapper ugmWrap = new UserGroupMemberWrapper();
                ugmWrap.UserName=MapUser.get(gm.UserOrGroupId).name;
                ugmWrap.grpMember=gm;
                listUserGroupMemberWrapper.add(ugmWrap);
            }
        }

        return null;

    }

    public class UserGroupMemberWrapper{
        public String UserName{get;set;}
        public GroupMember grpMember{get;set;}

        private UserGroupMemberWrapper(){
            grpMember = new GroupMember();
        }

    }
}
