# DateTimeMaskedTextProvider class

Namespace: [Eto.Forms](https://eto.picoe.ca/api/namespace/eto.forms.md) · Assembly: [Eto](https://eto.picoe.ca/api/assembly/eto.md) · Since v2.12

```cs
public class DateTimeMaskedTextProvider : IMaskedTextProvider<DateTime?>
```

Masked text provider that edits a [DateTime](https://learn.microsoft.com/dotnet/api/system.datetime) value using a fixed, culture-aware date and/or time format.

**Remarks:** This provider encapsulates all of the date/time masking, parsing, clamping, and stepping logic so it can be used with either a [MaskedTextStepper<T>](https://eto.picoe.ca/api/type/eto.forms.maskedtextstepper-1.md) or a [MaskedTextBox<T>](https://eto.picoe.ca/api/type/eto.forms.maskedtextbox-1.md). For a stepper, the [DateTimeMaskedTextProvider.GetStepValue(int, int, int)](https://eto.picoe.ca/api/type/eto.forms.datetimemaskedtextprovider/getstepvalue.md) helper can be used from [TextStepper](https://eto.picoe.ca/api/type/eto.forms.textstepper.md)'s step handling to increment or decrement the segment at the caret. For a text box, simply assigning the provider gives masked, culture-aware date entry without stepping. The [DateTimeMaskedTextStepper](https://eto.picoe.ca/api/type/eto.forms.datetimemaskedtextstepper.md) control wraps this provider with the appropriate control configuration.
