Properties

AcceptsWhiteSpaces

Get or set whether white space characters can be accepted or not.

public bool AcceptsWhiteSpaces { get; set; }

Property Value

bool

IsTextValid

Override this property to change the style for a control class, returning the type that you wish the elements to be styled as.

ValidationDelay

Get or set the delay of validating text after user typing in milliseconds.

public int ValidationDelay { get; set; }

Property Value

int
