ContainerControl.Validate ContainerControl.Validate ContainerControl.Validate ContainerControl.Validate Method

Definition

Verifies the value of the control losing focus by causing the Validating and Validated events to occur, in that order.

Overloads

Validate() Validate() Validate() Validate()

Verifies the value of the control losing focus by causing the Validating and Validated events to occur, in that order.

Validate(Boolean) Validate(Boolean) Validate(Boolean) Validate(Boolean)

Verifies the value of the control that is losing focus; conditionally dependent on whether automatic validation is turned on.

Validate() Validate() Validate() Validate()

Verifies the value of the control losing focus by causing the Validating and Validated events to occur, in that order.

public:
 bool Validate();
public bool Validate ();
member this.Validate : unit -> bool
Public Function Validate () As Boolean

Returns

true if validation is successful; otherwise, false. If called from the Validating or Validated event handlers, this method will always return false.

Remarks

The Validate method validates the last child control that is not validated and its ancestors up through, but not including, the current container control. This overloaded version always performs validation, regardless of the value of the AutoValidate property of the control's parent. Therefore use it to unconditionally force validation.

Verifies the value of the control that is losing focus; conditionally dependent on whether automatic validation is turned on.

public:
 bool Validate(bool checkAutoValidate);
public bool Validate (bool checkAutoValidate);
member this.Validate : bool -> bool
Public Function Validate (checkAutoValidate As Boolean) As Boolean

Parameters

checkAutoValidate
Boolean Boolean Boolean Boolean

If true, the value of the AutoValidate property is used to determine if validation should be performed; if false, validation is unconditionally performed.

Returns

true if validation is successful; otherwise, false. If called from the Validating or Validated event handlers, this method will always return false.

Remarks

The Validate method validates the last child control that is not validated and its ancestors up through, but not including, the current container control. This overloaded version performs validation based on the following conditions:

  • If the checkAutoValidate parameter is true, validation always occurs for child controls that are not validated.

  • If the checkAutoValidate parameter is false, validation occurs only if the AutoValidate property of the control's parent is enabled.
