Hi All,

I need help to get the picklist values and using these values in visualforce page to hide/show the pageblock.

My requirement.
I have a object called Book in may app . Book have one field called sample1(picklist) and  it has two values..(Yes, No).

Then , I have to show entire panel based of these values( yes, or no) . Below is my code.

Apex class :
public class bookcontrol
{
public list<Book__c> allbooks {get; set;}

public list<Book__c> getBooks()
{
allbooks= [select sample1__c from Book__c where sample2 = :object2.field2 limit 1 ];
return allbooks;
}
}
(there is some logic behind the above SOQL query, it is checking another condition)


Here my question is above returened " allbooks" have my field picklist values are not?

can i use above variable in visualforce page.

My visualforce page is :
.........
......
<apex:panelGroup rendered = "{! IF(allbooks.sample1__c == 'Yes' , true, false)">
........
.......
</apex:panelGroup>

Will that above code wii work?

How to get those picklist values to my visualforce page to compare the logic. I need to show that entire panel if my field value is Yes.

Appreciate your help. 

Thanks

    for(Account a : Trigger.new){
      if(a.Description == NULL)
         a.addError('You must add a value');
    }
}

Hi, 

I have two objects employee__c and department__c where employee__c is the child object for department__c. My requirement is if a child record is added then the description__c field in master record should get updated. Below  is my code but it is showing Error: Compile Error: IN operator must be used with an iterable expression at line 3 column 36. Any help is appreciated.

map<id, employee__c> myid = new map<id, employee__C>([select id, department__r.id from employee__c where id in:trigger.new]);
list<department__c> depstoupdate = [select name, description__c from department__C where id in:myid];
for(department__c d : depstoupdate){
d.description__c = 'The last employee added to this department is on ' +system.today();
}
update depstoupdate;
