nbk How to hide page block section
Hi Everybody,
My visualforce page having 2 sections(Account and Contacts). If the Account having any contacts need to display Contacts section other wise display only Account section.
Used following statement in VFP, but contacts section visible even no records exists on Contact object to corresponding Account Id
<apexageblockSection columns="5" Title="Contacts" rendered="{!NOT(ISNULL(contactsLst))}">
Can you please share your ideas.
Thanks,
Krishna
Hi Krishna,
Instead of check NULL for the contact list, try using the list size.
something like
<apex:pageBlockSection rendered="{!IF(contactsLst.size>0, true, false)}">

You may also use:
<apex:pageBlockSection rendered="{!NOT(contactsLst.empty)}">Hi,
I have 2 Page Blocks in my Visualforce page.
1) In which i will give Email as input text for searching any record is there in the Data base with that Email Address if there a record found in DB then it will pull the record and Display it in the VF Page.
On fetching the record with the Email Address i want to Hide/Display 2nd Page block section.
In 2nd PageB lock Section we have fields like Name, Email, First Name, Last Name to create a New Contact record and Email as Unique record to fetch the Record details from the Data BAse.
2) When a user gives Email Address and Search for a Record in the data base using the Email as input text if there is NoRecord found in the DataBase i want to See the Page Block section where User can give the Input for creating the New Conatct Record.
can anyone provide me sample Example for this................
I can able to fetch the Record using the Email Address and when i fetch the record i can see the Form page which i don't want to see when the record is found in the Data BAse . I want to hide it when a matching record is found with the Email Address
