NameDescription
System_CAPS_pubpropertyErrorMessage

Gets or sets an error message to associate with a validation control if validation fails.(Inherited from ValidationAttribute.)

System_CAPS_pubpropertyErrorMessageResourceName

Gets or sets the error message resource name to use in order to look up the ErrorMessageResourceType property value if validation fails.(Inherited from ValidationAttribute.)

System_CAPS_pubpropertyErrorMessageResourceType

Gets or sets the resource type to use for error-message lookup if validation fails.(Inherited from ValidationAttribute.)

System_CAPS_protpropertyErrorMessageString

Gets the localized validation error message.(Inherited from ValidationAttribute.)

System_CAPS_pubpropertyOtherProperty

Gets the property to compare with the current property.

System_CAPS_pubpropertyOtherPropertyDisplayName

Gets the display name of the other property.

System_CAPS_pubpropertyRequiresValidationContext

Gets a value that indicates whether the attribute requires validation context.(Overrides ValidationAttribute::RequiresValidationContext.)

System_CAPS_pubpropertyTypeId

When implemented in a derived class, gets a unique identifier for this Attribute.(Inherited from Attribute.)

NameDescription

System_CAPS_pubmethodGetType()

Gets the Type of the current instance.(Inherited from Object.)

System_CAPS_pubmethodGetValidationResult(Object^, ValidationContext^)

Checks whether the specified value is valid with respect to the current validation attribute.(Inherited from ValidationAttribute.)

System_CAPS_pubmethodIsDefaultAttribute()

When overridden in a derived class, indicates whether the value of this instance is the default value for the derived class.(Inherited from Attribute.)

System_CAPS_pubmethodIsValid(Object^)

Determines whether the specified value of the object is valid. (Inherited from ValidationAttribute.)

System_CAPS_protmethodIsValid(Object^, ValidationContext^)

Determines whether a specified object is valid.(Overrides ValidationAttribute::IsValid(Object^, ValidationContext^).)

System_CAPS_pubmethodMatch(Object^)

When overridden in a derived class, returns a value that indicates whether this instance equals a specified object.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfo(UInt32, UInt32, IntPtr)

Retrieves the type information for an object, which can be used to get the type information for an interface.(Inherited from Attribute.)

System_CAPS_pubinterfaceSystem_CAPS_privmethod_Attribute::GetTypeInfoCount(UInt32%)
