This post describes how you can suppress global item validation rules for individual items using version 6.4 of the Sitecore ASP.NET web CMS.
The Client Configuration Cookbook provides information validating data with Sitecore. Sitecore 6.4 introduces the ability to suppress specific validation rules for individual items. With 6.4, you can disable global item validation rules for individual items.
In the Content Editor, entries in the validation bar (to the right of the editing pane) indicate item validation violations. If you right-click on an entry, Sitecore presents available validation actions to resolve the violation. Sitecore 6.4 adds a default item validation action to suppress the validator for the item. If you click that action, Sitecore adds the validator to the __Suppressed Validation Rules field defined in the standard template. The validation bar does not process the validators specified in this field.
In the 6.4 technical preview, the __Suppressed Validation Rules field uses the obsolete "memo" field type. I expect that before release, Sitecore will change the field type to something more appropriate, such as Treelist.
Is there a way to reverse the Suppressed Validation Rule for the item once it has been suppressed.
@John: Sorry for the delayed response. I would expect that you just clear the __Suppressed Validation Rules field?
I'm guessing it's not possible but, is there a way to have the validation rule only apply to one template instead of the other way around? I have a client who wants to require one selection on tagging for our News template but no other.
@Ben: possibly some pointers in www.sitecore.net/.../All-About-Validation-with-the-Sitecore-ASPNET-CMS.aspx and sdn.sitecore.net/.../Client Configuration Cookbook.aspx If I understand correctly: How to Configure Validation Rules for a Specific Data Template Field To configure validation rules for a specific data template field: 1. In the Template Manager or the Content Editor, select the data template field definition item. 2. In the Validation Rules section, configure field validation rules. One problem would be if you inherit that field from another data template, in which case options would include custom validators and possibly other approaches.
