Remarks
Validation groups allow you to assign validation editors on a page to a specific category. Each validation group can be validated independently from other validation groups on the page. Use the ValidationGroup property to specify the name of the validation group for the current editor.
When the ValidationSettings.CausesValidation property is set to true, the ValidationGroup property specifies a validation group that is validated when the editor posts back to the server. If you do not specify a value for this property and the ValidationSettings.CausesValidation property is set to true, all validation controls on the page that are not assigned to a validation group are validated when the editor posts back to the server.
In order to validate a group of input controls on the client, you can use the following client methods: ASPxClientEdit.ValidateGroup, ASPxClientEdit.ValidateEditorsInContainer, ASPxClientEdit.ValidateEditorsInContainerById.
