I have a CommandButton when the user clicks it adds the selected records and post it to the controller but it repaint the entire page and I'm wondering how can I do using async in VFP without reloading the entire page?

   <apex:pageblock id="Selected_PBS" title="{!IF(SelectedContacts != NULL && SelectedContacts.size > 0,'Selected Contact','There are no records selected')}">   
        <div align="center" style="padding:15px;" rendered="{!IF(SelectedContacts != NULL && SelectedContacts.size > 0,'Selected Contact','There are no records selected')}">            
              <apex:commandButton value="Add to Work Order!" action="{!addToWO}" disabled="{!If(selectedContacts != null && selectedContacts.size > 0,false, true)}" />
        </div>
        <apex:pageBlockTable value="{!SelectedContacts}" var="contact" rendered="{!IF(SelectedContacts != NULL && SelectedContacts.size > 0,true,false)}">
             <apex:column value="{!contact.Name}"/>
             <apex:column value="{!contact.Email}"/>
             <apex:column value="{!contact.Phone}"/>
        </apex:pageBlockTable>
    </apex:pageBlock>

  • just what ever you need to or nothing at all. But it does not make a good user experience to execute an action and have absolutely no indicator on the page that it actually happened. If you choose to serenader nothing simply add rerender=""

You can use the rerender attribute on the tag. Give your pageBlockTable an id, then you can do something like:

<apex:commandButton rerender="[myPageBlockTableId]" ... /> 

This should make your action an ajax call.

Alternatively you can create remote actions in your controller and handle the dom manipulation yourself with a different client side framework. It's more low level but gives you more control.
