  • 1. Leverage StandardSetController inApex and VisualforceDeveloper Track 2012Nebojsa (Nash) Zgonjanin, CRM DeveloperOnPath Ottawa, Ontario, Canada (www.onpath.com)Nebojsa.zgonjanin@onpath.com@Nzgonca.linkedin.com/in/nashzgonjanin
  • 2. Abstract• Do you use list view filters?• Would you like to use that same logic in your Visualforce pages?• Don’t reinvent the wheel• Save time, and make your admin happier as well
  • 3. Nebojsa (Nash) Zgonjanin CRM Developer • Salesforce MVP (winter 2012), • Salesforce developer more than 6 years, • Senior developer (MS .NET) more than 15 years, • Work for www.OnPath.com, Ottawa, Ontario, Canada
  • 4. Session Objectives• StandardSetController and List View Filter Criteria (logic)• jQuery Table Sort and Visualforce page• Hierarchy Custom Setting used to control functionality per org (profile or user level)• Demo ”Add to Campaigns” of implemented technology
  • 5. Session Objectives• Short live demo of application to familiarize audience with topic• Use of Eclipse to browse code and point to key moments• Code in PPT presentation is used as reference
  • 6. Solution Intro I• StandardSetController and List View Filter Criteria• Define StandardSetController (SOQL query)• Apply Filter Criteria from List View to StandardSetController• Execute SOQL and use in Apex code
  • 7. Solution Intro IIjQuery Table Sort and Visualforce Page• jQuery Setting • Static resources • <apex:includeScript>• Mash up of: • standard HTML table tags • <apex:repeat> tag • jQuery <script> code
  • 8. Solution Intro IIIHierarchy Custom Settings (Levels of use)• Org default• Profile (group of users)• User (individual)• Use of setting values in Apex code• Use of setting values in Visual Force page• Demo: User (Serbian) vs. Org Default (English)

  • 11. Solution intro I always wanted to leverage platform functionality and addmore of client side functionality that browser bring in game. Combination of APEX controller extension and standardcontrollers (ApexPages.StandardController andApexPages.StandardSetController) give me option to leverage standardplatform functionality and add more flexibility and user interfacefunctionality to Visual Force page using jQuery Table sorter(jquery.tablesorter.min.js) add on, that enable sorting of multiplecolumns. Using Custom setting I made available different set ofparameters to be used per Org; Profile or User (labels, list views forfiltering, Error Messages…) that enable easy internationalization ifneeded.
  • 12. Objectives and Solution I What is the Add to Campaigns app Salesforce.com provides features for adding many people to asingle campaign, but what about an organization that managesmultiple, ongoing campaigns like newsletters, customer programs,annual events, and even holiday card lists? Manually adding a single person to multiple campaigns one byone is a pain, and contributes to poor adoption, and incomplete orunusable data. This app application in salesforce.com allows users to add asingle contact or lead to multiple campaigns with as few clicks aspossible.
  • 13. Objectives and Solution II There are two portions to this application: end-user and administrator (non-developer). NOTE: Custom Settings, Standard List View filter, Standard Controller,StandardSetController are used to give end user (administrator) flexibility to manage dataset used for app in combination with visual force pageADDTOCAMPAIGNS_LISTVIEWFILTER or using standard List View management underCampaigns tab. The end-user portion of the application works the same for both contacts andleads. Add a custom button to the Campaign History related list for both Leads andContacts called "Add to Campaigns". When the end-user clicks this button display a list ofcampaigns with check boxes and a "check all" option. (The query for the list of campaignswill be determined in the administrator portion of the application.) When the end-usersubmits the form, insert the contact/lead to the campaign as member with the defaultstatus for that campaign and return the user back to the standard contact/lead detailspage.

  • 22. Custom Setting Hierarchy type overviewHierarchy Custom Settings: A type of custom setting that uses a built-in hierarchical logic that lets you “personalize” settings for specific profiles or users. The hierarchy logicchecks the organization, profile, and user settings for the current user and returns the most specific, or “lowest,” value. In the hierarchy, settings for an organization areoverridden by profile settings, which, in turn, are overridden by user settings.https://na14.salesforce.com/help/doc/user_ed.jsp?loc=help&target=cs_manage_data.htm&section=integrate
