Hai friends,
I came with new post, This Post illustrates how to display Multiselect Picklist on Vfpage and how the values are populating into multiselect picklist.I am giving example like, we can field Type picklist on account pagelayout,now i am taking that field and populating that fields data in to multiselect picklist and selected values in to new field 'Selected values' custom field and while editing that record,loading values in to multiselect picklist.
First we need to get the picklist values,for this we need to use describe object methods.
Schema.DescribeFieldResult fieldResult = Schema.sObjectType.Account.fields.Type.getSObjectField().getDescribe();
List<Schema.PicklistEntry> ple = fieldResult.getPicklistValues();
for( Schema.PicklistEntry f : ple)
{ options .add(new SelectOption(f.getLabel(), f.getValue())); originalvalues.add(f.getLabel()); system.debug('********PICK*******'+originalvalues); }
for( Schema.PicklistEntry f : ple)
{ options .add(new SelectOption(f.getLabel(), f.getValue())); originalvalues.add(f.getLabel()); system.debug('********PICK*******'+originalvalues); }
we can use above code to get all the picklist values from Type field from Account object.
Now we need to load this values in to select options and process the remaining functionality,i am giving total code for that please go through that you can understand the functionality
Controller

Vfpage1:-

<apex:form >
<apex:pageBlock tabStyle="Contact">

<apex:panelGrid columns="10" id="abcd">
<apex:outputLabel > Type:</apex:outputLabel>
<apex:selectList id="sel1" value="{!leftselected}" multiselect="true" style="width:150px" size="5">
<apex:selectOptions value="{!unselectedvalues}" />
</apex:selectList>
<apex:panelGroup >
<br/>
<apex:image value="{!$Resource.multiselect}">
<apex:actionSupport event="onclick" action="{!selectclick}" reRender="abcd"/>
</apex:image>
<br/><br/><apex:image value="{!$Resource.multiunselect}">
<apex:actionSupport event="onclick" action="{!unselectclick}" reRender="abcd"/>
</apex:image>
</apex:panelGroup>
<apex:selectList id="sel2" value="{!rightselected}" multiselect="true" style="width:150px" size="5">

</apex:selectList>
</apex:panelGrid>
<apex:commandButton value="Save" action="{!Save}"/>
</apex:pageBlock>
</apex:form> </apex:page>
Execute this by passing id to this page as Query string parameter.
please make sure before trying this,create a field "Selected_Values__c".
and upload select and unselect arrows in the static resources
