When overridden in a derived class, validates the text displayed in the up-down control.
[Visual Basic] Protected Overridable Sub ValidateEditText() [C#] protected virtual void ValidateEditText(); [C++] protected: virtual void ValidateEditText(); [JScript] protected function ValidateEditText();
Some examples of validation include comparing the text entered to the data type set in your derived class, comparing it to a list of values, or verifying it 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 property of the up-down control. This method will be called if the UserEdit property is set to false when the Text property is set.
