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. In such case, we cannot use required = “true” attribute, because it will make check for mandatory in all the scenario.

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

Sometimes I need things done quickly, easily, and preferably with as…

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. I’m a bit older now, a bit…

I recently came across an interesting discussion where adding new field to a Object broke some of existing code. It’s strange right, mostly removing or renaming fields is risky, as they could break some String expressions or merge fields.

<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.
