Building Visualforce pages for Standard Pages : Part 3 – Case Edit Page

Building Visualforce pages for Standard Pages : Part 3 – Case Edit Page

Continuing my series of posts about building Visualforce pages that mimic standard Salesforce pages, here’s the code for the Case Edit page. This one needs an extension class as well, since some of the functionality cannot  be achieved using just Visualforce. Checkout how the Assignment rules are being set in Apex.

Steps to use this template
1. Create a Visualforce page (I used the name “CaseEdit”), and copy all the code below.
2. Create an Apex Class (I used the name “CaseEditExtension”), and copy all the code from the Apex extension below.
2. Save the page, and test it by visiting the URL below, making sure to pass an existing case ID as a parameter (refer to my article here if you are fuzzy about Salesforce URLs)  :-

https://{your org}.visual.force.com/apex/CaseEdit?id=005E000000HCekM&retURL=%2F005E000000HCekM

3. Create a custom “Edit” button for Case, that takes you to this page when clicked.
