# Validate data template field values

To validate data entered into data template fields, you configure [validation rules](https://doc.sitecore.com/xp/en/developers/105/sitecore-experience-manager/validation-rules-and-options.html "Validation rules and options") in the data template field definition items.

To configure validation rules for a data template field:

1. In the Template Manager or the Content Editor, click the data template that you want to add validation to.
2. On the **Content** tab, in the **Validation Rules** section, select the relevant validation rules.
