What is it for ?

  I have been blogging & publishing videos for Salesforce Developers for quite sometime. But, it looks like more of a one way communication. So, i thought to create a community where we actively discuss about various development issues & get to know about each other & help each other. Here's the few things i'm expecting to deliver through this community,

• Tutorials
• Share Development Tips & Tricks
• Online Events (like coding puzzles, bootcamp, etc)
• Weekly Hangouts
• Personalized Training (one to one)

What is next ?

  As soon as i reach 10 members in the community, i'm going to schedule a launch event & discuss about the community & chit chat with the people to get to know about each other.

Visualforce - Beyond Basics Series 47 - Extend standard sObject

What is the purpose of extending the sObject ?

There's no inheritance to standard sObject. So, if one wants to extend the record, one need to create a wrapper to store the record inside it.

The wrapper is a Apex Class which will have the record and other extended fields. So, in visualforce page, both standard and extended fields can be used seamlessly.

Visualforce - Beyond Basics Series 46 - Treat each User differently

What is Personalization ?

Sometimes Visualforce page needs to behave or look differently for different set of users. This is called Personalization.

How do achieve this ?

In salesforce, we can use 'Custom Settings' to store the personalization data for User, Profile or entire Organization. We need to be very careful in not misusing this. If any data that does n't different between user, then it's App Configuration which should be stored in 'Custom Metadata'.

Visualforce - Beyond Basics Series 45 - Keep the pages alive

What is keep-alive for the page ?

For every visualforce page, there's a timout for session, after which the session expires. This is configurable under security controls in Salesforce Setup. Normally, it will be few minutes in best secured Org.

How to prevent that ?

But, practically, you might have a visualforce page which requires more time for the User to work on it. Say, if they take 30min to configure products for an opportunity, then, they were pulled for a meeting. So, when they come back after 30 min & click save, they should be disappointed to see login page & potentially losing all the effors.

To avoid such scenarios, we can use actionPollar to poll for an empty request to server, so that session will be kept alive forever.

The best way to achieve inlineEdit for fields in Visualforce is using mode = 'InlineEdit' in PageBlock tag. This is the best and efficient way to do it. However, there's only one inconvenience, it opens up only one field for editing.
