C wpf textbox validating
This is the working code that changes the Background of a Text Box in case of error.The validated event works the same, only pass it the name textbox instead.Here is just the validating event handler’s code: The event driven validation model in Win Forms is powerful and flexible enough to allow you to create high quality apps that implement robust and maintainable validation code in your forms.A Text Box control is used to display, or accept as input, a single line of text. It can contain only unformatted text in its Text property.
So I should use it to change the color of the Background. The default property values of the properties that are set by Template Binding can be set by other Setters.
