ContainerControl.Validate Method (Boolean)

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

Namespace:  System.Windows.Forms
Assembly:  System.Windows.Forms (in System.Windows.Forms.dll)

public bool Validate(
	bool checkAutoValidate
)

Parameters

checkAutoValidate
Type: System.Boolean

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

Return Value

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

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.
