EditContext.IsValidationFaulted Method

Definition

Namespace:

Microsoft.AspNetCore.Components.Forms

Assembly:

Microsoft.AspNetCore.Components.Forms.dll

Package:

Microsoft.AspNetCore.Components.Forms v11.0.0-preview.5.26302.115

Overloads

Name	Description
IsValidationFaulted()	Returns true if the most recent ValidateAsync(CancellationToken) pass observed an unhandled exception from any OnValidationRequestedAsync handler. A subsequent successful ValidateAsync(CancellationToken) pass clears the flag; a caller-cancelled pass preserves it. Use this to detect that validation itself failed (not just produced validation messages). For per-field validator faults from AddValidationTask(FieldIdentifier, Task, CancellationTokenSource), use the IsValidationFaulted(FieldIdentifier) overload.
IsValidationFaulted(FieldIdentifier)	Returns true if the specified field's last async validation faulted (threw a non-cancellation exception).
IsValidationFaulted<TField>(Expression<Func<TField>>)	Returns true if the field identified by the accessor expression's last async validation faulted (threw a non-cancellation exception).

member this.IsValidationFaulted : unit -> bool

Public Function IsValidationFaulted () As Boolean

Returns

Boolean

true if the most recent ValidateAsync(CancellationToken) pass faulted; otherwise false.

IsValidationFaulted(FieldIdentifier)

Source:

EditContext.cs

Returns true if the specified field's last async validation faulted (threw a non-cancellation exception).

public bool IsValidationFaulted(in Microsoft.AspNetCore.Components.Forms.FieldIdentifier fieldIdentifier);

member this.IsValidationFaulted : FieldIdentifier -> bool

Public Function IsValidationFaulted (ByRef fieldIdentifier As FieldIdentifier) As Boolean

Parameters

fieldIdentifier

FieldIdentifier

Identifies the field to query.

Returns

Boolean

true if the field's last async validation faulted; otherwise false.

IsValidationFaulted<TField>(Expression<Func<TField>>)

Source:

EditContext.cs

Returns true if the field identified by the accessor expression's last async validation faulted (threw a non-cancellation exception).

public bool IsValidationFaulted<TField>(System.Linq.Expressions.Expression<Func<TField>> accessor);

member this.IsValidationFaulted : System.Linq.Expressions.Expression<Func<'Field>> -> bool

Public Function IsValidationFaulted(Of TField) (accessor As Expression(Of Func(Of TField))) As Boolean

Type Parameters

TField

The type of the field.

Parameters

accessor

Expression<Func<TField>>

An expression that identifies the field, e.g. () => model.Email.

Returns

Boolean

true if the field's last async validation faulted; otherwise false.
