Gets or sets a value that determines how an input character that matches the prompt character should be handled.
true if the prompt character entered as input causes the current editable position in the mask to be reset; otherwise, false to indicate that the prompt character is to be processed as a normal input character. The default is true.
The MaskedTextBox can treat two categories of characters—spaces and prompt characters—specially. Typically, each input character will be tested against the mask and either accepted or rejected. Assuming that the PromptChar property is set to non-a null reference (Nothing in Visual Basic), then setting the ResetOnPrompt property to true will result in special processing for the prompt character. When the user enters the prompt character into the mask, it causes the current mask character position to be cleared and the current position to be advanced to the next editable character.
