***Urgent Help*** adding Command link to rerender few dynamic fields on VF

Hi All,

 

I have a requirment in the VF page as :

required+Optional is a link and on clicking on which the 5 fields mentioned below need to be re rendered.

by default office name , Address 1 , city and state would be seen. After clicking on Required+optional link, the page should show Address2  and the link name should get changed to "Required Only". And another click on the          "Require Only" link should changed back to "Required+Optional" Can someone please help me with the code. All the fields are created in a object called Office Location.

 

                                 Required+optional

 


Office name

Address 1                                                                            -- This field will have to be shown only when link is clicked

Address 2

City

State

 

 

Thanks

Hi Ashish,

 

Thanks for your reply.

 

I tried the  code u had given , what it does is when the page is loaded, the Address 2 field is hidden coz of the rendered functionality, but the link Required+only stay as it is.

 

At first I will display Required+only Link. with the address2 field hidden. 

When i click on Required+Only The field Address2 should be visible and the link name should change to Required

 

similarly when the Required  is visible and clicked on it, it should hide the address2 field and change the link name to Required+Optional

 

 

Please help me with your expertise.

 

Thanks

Ashish,

 

Please take a look at my code :

 

VF page :

 

<apex:pageBlocksection id="section" columns="2" title="Personal Information" collapsible="false">
              <apex:panelGrid width="700" columns="3">
              <apex:outputlabel ></apex:outputlabel>
              <apex:outputlabel ></apex:outputlabel>
              <apex:commandLink value="(Required + Optional)" action="{!Test}" reRender="section" rendered="{!visible!='hi'}"/>
              <apex:commandLink value="(Required Only)" action="{!Test1}" reRender="section" rendered="{!visible=='heloo'}"/>
              
                    <apex:outputLabel value="Prefix" for="prefix" rendered="{!visible=='hi'}"/>
                    <apex:inputText required="false" id="prefix" value="{!prefix}" rendered="{!visible=='hi'}"/>
                    <apex:outputlabel ></apex:outputlabel>
                    <apex:outputLabel value="First Name" for="fname"/>
                    <apex:inputText required="false" id="fname" value="{!fname}"/>
                    <apex:outputlabel ></apex:outputlabel>
                    <apex:outputLabel value="Last Name" for="lname"/>
                    <apex:inputText required="false" id="lname" value="{!lname}"/>
                    <apex:outputlabel ></apex:outputlabel>
                    <apex:outputLabel value="Middle Initial" for="mini"/>
                    <apex:inputText required="false" id="mini" value="{!mini}"/>
            </apex:panelgrid>
            </apex:pageblockSection>

 

 

and have added the two methods as suggested in My controller :

 

 public PageReference Test(){
            visible = 'hi';
            return null;
        }
        
        public PageReference Test1(){
                     visible = 'heloo';
                     return null;
                }

.

What is happening is,

it is showing the Required+Optional link with the prefix field hidden.

I want the prefix field hidden with Required+Optional and on click of it, the link name should change to Required Only and prefix field to be visible.

 

Please correct me.

 

Thanks

Manju

Hi

   You need to change this line

             <apex:commandLink value="(Required Only)" action="{!Test1}" reRender="section" rendered="{!visible=='heloo'}"/>

      please write

            <apex:commandLink value="(Required Only)" action="{!Test1}" reRender="section" rendered="{!visible=='hi'}"/>.

 

  when you run the page Prefix field will be hidden ..when you click on Required+optional then Prefix is visible and link is changed ti Required only .

 After that when you click on Required only link then again Prefix field will be hidden and link is changed to Required+optional

 

Did this answers your problem ...please mark it solved

 

thanks

Hi,

 

No luck ashish..

 

I dont know what is causing this issue. The prefix field is hidden when the page is first loaded, but is not visible on click.

Any other thing we can do ? Please help.

 

Also just wanted to know, in the test method,

 

we set the visible = 'hi' and return null. should we make any changes here ?

 

Thanks

Hi Ashish,

 

Is there anyway we can fix the alignment of the required+optional link and required only link?

I mean, required only should be replaced in the same place where required+optional will be present at first instance..

 

Thanks
