When overridden in a derived class, validates the text displayed in the spin box (also known as an up-down control).
Assembly: System.Windows.Forms (in System.Windows.Forms.dll)
Some examples of validation include comparing the text entered to the data type set in your derived class, comparing the text to a list of values, or verifying the text to be within a range of values.Notes to Inheritors
When overriding this method in a derived class, be sure to add code in this method to validate the text of the spin box. This method will be called if the UserEdit property is set to false when the Text property is set.
