abstract member AddAndTrackValidationAttributes : Microsoft.AspNetCore.Mvc.Rendering.ViewContext * Microsoft.AspNetCore.Mvc.ViewFeatures.ModelExplorer * string * System.Collections.Generic.IDictionary<string, string> -> unit
override this.AddAndTrackValidationAttributes : Microsoft.AspNetCore.Mvc.Rendering.ViewContext * Microsoft.AspNetCore.Mvc.ViewFeatures.ModelExplorer * string * System.Collections.Generic.IDictionary<string, string> -> unit

Parameters

viewContext: ViewContext

A ViewContext instance for the current scope.

modelExplorer: ModelExplorer

The ModelExplorer for the expression.

expression: String

Expression name, relative to the current model.

attributes: IDictionary<String,String>

The Dictionary<TKey,TValue> to receive the validation attributes. Maps the validation attribute names to their String values. Values must be HTML encoded before they are written to an HTML document or response.

Tracks the expression in the current FormContext to avoid generating duplicate validation attributes. That is, validation attributes are added only if no previous call has added them for a field with this name in the <form>.
