RED Bar on Fields in VisualForce

Some times we need to show vertical Red Bar on few fields, which are mandatory on certain scenario, such as mandatory only while creation but should be optional on editing exisiting records.

This can be handled by adding few more lines to the visual force page, so that validation…

A better way to work with jQuery selectors and Visualforce Component Ids

This tricky topic had me puzzled for some time and in earlier posts I went the way of using CSS classes to identify DOM elements; but was always a touch dissatisfied with the solution. Not only is it less efficient – valid XHTML pages should only have one element with any Id, although CSS classes can be shared by many elements – but it also feels all hacky ‘n stuff.

Cancelling out of HTML5 browser validations !

This post is based on a short scary movie, I was working on a cool HTML-5 page

 <apex:page .... docType="html-5.0"/>

But all the coolness disappeared when powers of CANCEL button are gone. The typical Cancel button in salesforce, which is always tough enough to get out of any validation, i.e.

<apex:commandButton action="{!cancel}" value="Cancel" immediate="true" />

On hitting the cancel…

Best Practices – Salesforce

2. Try using standard set controller pagination option provided by Salesforce when doing pagination. Now we have also got OFFSET keyword which…
