Heads Up: Custom Home Page Components Using iFrames may stop working in Summer 15

SidebarSummary

In preparation for my upcoming Visualforce course on Lynda, I discovered something that I think may have a big impact on some people out there that are using iFrames to embed a Visualforce page in the Sidebar. I have seen this technique used by several people over the years to display data in the sidebar and up until just recently the only way to accomplish this was to create a […]

Top 5 Tips for Improving Visualforce Pages

top5

#1 – Reduce or eliminate view state   View State is not your friend when it comes to page performance, so if you do not need it (as in your page does need to persist data between page requests), then do not use it at all. This is especially true for pages that will run on the Salesforce1 mobile platform!!! How do you not use it all? Do not include the […]

Considerations when using Javascript in Visualforce

JS

As part of my research for the new Lynda.com course I am doing on Visualforce, I have been going through posts on the Salesforce forums. I ran across this one in which the poster was asking what was the best way to select multiple checkboxes on a Visualforce page when a “Check All” checkbox was selected. The best answer that was chosen was a recommendation by someone to use the […]

Add Audio/Video Conferencing to Any Visualforce Page with GoInstant

It is very likely you missed the announcement less than two years ago about Salesforce acquiring a Canadian-based company named GoInstant. It is also likely that even if you attended Dreamforce in late 2013, you missed a very informative session titled, “Build Real-time Multi-User Apps with Visualforce, GoInstant and AngularJS“. From what I can tell, not much fuss has been made so far about the Backend-as-a-Service provider that was founded […]

Book Review: Visualforce Development Cookbook

VisualforceDevelopmentCookbook

Not a book for beginners, but GREAT for seasoned Apex developers I recently had the honor of reviewing the recently published, Visualforce Development Cookbook. The code recipes are great and could really go far in demonstrating the potential of the platform. It is obvious that the author, Keir Bowden has implemented many, if not all of these recipes in real-world scenarios. However, I think this is a dangerous book for […]

Custom Components Not Rendering Properly

CustomComponentsShot1

After much searching, I have finally figured out what was causing two frustrating issues I have run into several times and thought I would share it with everyone. Both issues involve creating a Custom Component that includes HTML. If you use an iframe tag to reference an existing Visualforce page and do not include a certain switch in your URL, the component will not be rendered properly and instead of […]

Proper Use of ActionStatus component

ActionStatusProblemCode

In preparation for the Advanced Developer exam, I have been painstakingly going page by page through the Visualforce Developers Guide (which can be found online here). Almost every single person that has passed the exam has suggested that you become intimate with this document, but I wonder how many people truly are. I keep finding that the code listed in the tutorials does not work as it should. My last […]

Setting Tab Order – Use TabOrderHint instead of TabIndex

In the last few days, I have been preparing for the Advanced Developer Certification by going page by page through the recommended Salesforce Developers Guide. I was shocked when I received an error trying to save a sample page using the code supplied in the online guide (page 39). The sample page involved setting the tab order for fields in a form and the code referenced an attribute named TabIndex. […]

Dynamic Visualforce Components and Tips

DynamicComponents

Dynamic Visualforce Components Instead of markup, these components are designed in Apex Allows you to create pages that render based on a variety of states, such as user’s: Permissions Behavior Organization preferences Data attributes This can be useful when you need two users to view the same page, but customized for their needs. However, this should not be the main way a developer creates pages. These should only be used […]
