HxValidationMessage #
Displays a list of validation messages for a specified field within a cascaded HxValidationMessage.EditContext.
Reimplementation of Blazor ValidationMessage as Bootstrap 5 validation.
Used by HxInputBase and derived components.
You usually don't use the HxValidationMessage in your code directly. It is encapsulated in HxInputXy components.
Display modes #
You can select a display mode by setting the Mode parameter. It allows you to choose between Regular, Tooltip, Floating, and None.
For
HxInputXy components, the default ValidationMessageMode is Floating.
You can change the application-wide default by setting the HxInputBase.Defaults.ValidationMessageMode static property.
Custom validation message #
You can disable the encapsulated validation message with ValidationMessageMode="ValidationMessageMode.None" and use
your own instance of HxValidationMessage.
