Property Value

Type	Default	Description
String	String.Empty	A string value that specifies the validation group’s name.

Remarks

Validation groups allow you to assign the ASPxValidationSummary to the validation controls on a page (the ASPxValidationSummary‘s ValidationGroup property should be the same named with the control’s ValidationGroup property).

When you specify a value for the ValidationGroup property, only the errors after validation of the corresponding controls on the form ares displayed within the ASPxValidationSummary.
