Validation in Service Manager Custom Forms

Author by John Hennen

Building on my good buddy Christopher's recent blog posts about custom forms in Service Manager (Part 1, Part 2) today I'd like to talk about how to add validation to your custom forms.  This post assumes you know some of the basics about how to create custom forms using Visual Studio.  Also, it is worth pointing out that there are multiple ways to accomplish form validation.  Today I'll talk about how to use the validation that is built in to Service Manager. The first step is to add the necessary assembly as a reference to your project.  Specifically, you need to add Microsoft.EnterpriseManagement.UI.FormsInfra.dll, which is located in C:Program FilesMicrosoft System Center 2012Service Manager.

Next time - more on validation (including validation templates, which you can see I am using) and some other WPF tricks I've picked up along the way!
