Check if selected picklist value is one among other picklist

Consider 2 picklists

<apex:inputfield value="controller.picklist1__c"/>
and the second picklist, 'picklist2__c' has some values in it, Is there any way to check if selected value in picklist1__c is in picklist2__c. Thanks.

Like, IF(Selectedvalue(picklist1) is one of the field values of (picklist2))

Are you using vf page/apex controller for this? If yes, then in controller you can do this.

Let me know if you have any specific question.

Hi bob,

You can call onchange JavaScript method to invoke action where you can check whether the selected picklist1__c is in picklist2__c.

Zedroid.

Bob,

The code in the following post is a property you can add to your controller.  The set will contain all of the picklist values that are in common between the two picklists.  You can check to see if the chosen value is a shared value with:

set_PicklistValuesInCommon.contains( chosenValue )

In the code, replace "myObject__c" with whatever your object name is.

Let me know if you have any questions.

Whoops, I see a typo on line 14:  it should reference "Picklist2__c", not "Picklist1__c" again.
