See also the TextMaskFormat property to determine how the mask is stripped when reading the Text property.

TextMaskFormat

MaskFormat: Since 3.2.8 Returns or sets a value that determines whether literals and prompt characters are included in the Text value when the DateTimePicker also specifies a Mask. (Default: IncludeLiterals)

This property lets you control the value returned by the Text property when there is an edit Mask. The default is to remove the prompt and keep the literal in order to return a text value that can be parsed to a valid date: i.e. "1_/10/__23" is retuned as "1/10/23".Since 3.2.8 Note that when the value is null or empty, and regardless of the mask, the Text property returns an empty string.
