This post provides a code example for a multi-purpose Visualforce page that dynamically switches between Salesforce Classic and Lightning Experience (LEX) views based on the detected user setting. At some future stage (perhaps Dreamforce ’16 will enlighten us here) the platform will likely provide support for auto-conversion of legacy Visualforce assets to the new Lightning […]
Once again the annual Dreamforce event has been and gone leaving most practitioners with an uncomfortable knowledge deficit in terms of the real detail of the wealth of new innovations announced. This autumn period, post-Dreamforce, is often a time for investigation; piecing together information gathered from press releases, blog post, social media and event session […]
A quick post to outline an informal convention for the definition of a Visualforce controller class, key maintainability characteristics being predictable structure, readability and prominent revision history. All developers have a subjective preference in this regard, however consistency is key, particularly in the Salesforce context where multiple developers/consultancies contribute to a codebase over its lifetime. […]
At the time I started writing this post we were living in a Chatter Mobile world, this is no longer the case. As announced recently at Dreamforce ’13 we have entered the Salesforce1 era, the direction of which will no doubt become clearer as we transition to the Spring ’14 release. What is clear now […]
A real frustration with inline Visualforce pages (added to standard page layouts) is the static nature of the height setting. From the layout we can set a specific height, but ideally we want the height set dynamically from the content height. Sounds like a simple enough requirement, however, the fact that the VF page section […]
The newly released Salesforce Touch Platform Guide provides a very useful consolidation of both technical information and design guidance pertinent to mobile development on the Force.com platform. Topics covered include Identity, Connected Apps, Mobile Components for Visualforce etc. All in all an essential read for anyone considering mobile app development. Of particular interest is the […]
This tip introduces a simple pattern used by many AppExchange solutions to manipulate standard layouts. In short, a custom sidebar component is added which contains JavaScript code which manipulates the page at the DOM level. The following simple example shows how the country fields on the account layout can be changed to lists – a […]
In the very early 90s I was employed as a professional Visual Basic programmer (and no that isn’t a contradiction in terms) enjoying greatly the development of client-server accounting systems. Good times. In those days tips and tricks sites were a big part of how the community shared knowledge. Following some recent reminiscing, through this […]
As of the Summer ’12 release FieldSets can be accessed through Dynamic Apex (or Apex Describe). Remember, FieldSets are admin configured arbitrary groupings of fields, added on the object detail page within setup. With the upcoming release, controller code can now dynamically build a soql query that retrieves the data for the fields in the […]
The code below provides an example of a page action method used to detect a mobile user-agent and perform redirection. Alternatively the same approach could be used with dynamic Visualforce components to switch between mobile/web optimised page composition. [sourcecode language=”java”] public PageReference redirectDevice(){ String userAgent = ApexPages.currentPage().getHeaders().get(‘USER-AGENT’); //& some devices use custom headers for the […]
