# Resetting Form Fields

[RadPdfProcessing](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/overview) supports resetting form fields starting with Q1 2025. The `ResetFormAction` class represents an action that resets specific form fields in a document. The `Fields` property contains the list of field names that are *included* in the reset operation or *excluded* from it.

The `ResetFormType` property defines the type of the reset form behavior. The available options are:

| Value     | Description                                                       |
| --------- | ----------------------------------------------------------------- |
| `Include` | Specifies that the reset form includes the specified form fields. |
| `Exclude` | Specifies that the reset form excludes the specified form fields. |

## Creating a PushButtonWidget with a ResetFormAction

The following example shows how to create a document from scratch, add a form field (for example, `CheckBoxField`), and a push button that triggers the reset action for the checkbox when you click the button.

```C#
RadFixedDocument fixedDocument = new RadFixedDocument();
RadFixedPage fixedPage = fixedDocument.Pages.AddPage();
string fieldName = "SampleCheckBox";
CheckBoxField checkBoxField = new CheckBoxField(fieldName);
checkBoxField.IsChecked = true;

TwoStatesButtonWidget CheckBoxWidget = checkBoxField.Widgets.AddWidget();
CheckBoxWidget.Rect = new Rect(200, 200, 20, 20);

fixedDocument.AcroForm.FormFields.Add(checkBoxField);
fixedDocument.Pages[0].Annotations.Add(CheckBoxWidget);

PushButtonField pushButtonFieldReset = new PushButtonField("SamplePushButton");
PushButtonWidget buttonWidgetReset = pushButtonFieldReset.Widgets.AddWidget();
buttonWidgetReset.Rect = new Rect(0, 0, 250, 50);
buttonWidgetReset.HighlightingMode = HighlightingMode.InvertBorderOfAnnotationRectangle;

ResetFormAction resetFormAction = new ResetFormAction(new List<string>() { fieldName }, ResetFormType.Include);
buttonWidgetReset.Actions.MouseUp.Add(resetFormAction);

buttonWidgetReset.AppearanceCharacteristics.Background = new RgbColor(123, 165, 134);
buttonWidgetReset.AppearanceCharacteristics.NormalCaption = "Reset";

buttonWidgetReset.TextProperties.FontSize = 20;
buttonWidgetReset.TextProperties.Font = FontsRepository.Courier;
buttonWidgetReset.TextProperties.Fill = new RgbColor(0, 0, 0);
buttonWidgetReset.RecalculateContent();

fixedDocument.AcroForm.FormFields.Add(pushButtonFieldReset);
fixedDocument.Pages[0].Annotations.Add(buttonWidgetReset);
```

> important In **.NET Standard/.NET (Target OS: None)** environments, fonts beyond the [14 standard ones](https://www.telerik.com/document-processing-libraries/documentation/libraries/radpdfprocessing/concepts/fonts#standard-fonts) require a [FontsProvider implementation](https://www.telerik.com/document-processing-libraries/documentation/knowledge-base/pdfprocessing-implement-fontsprovider) to be resolved correctly.

## Updating an Existing Document with a Field

If the document already contains form fields and a `PushButtonWidget`, you can access the existing button and add the `ResetFormAction`.

```C#
PushButtonWidget resetPushButtonWidget = ((PushButtonField)fixedDocument.AcroForm.FormFields.Last()).Widgets.First();
ResetFormAction? resetAction = resetPushButtonWidget.Actions.MouseUp.First() as ResetFormAction;
string fieldNameToReset = fixedDocument.AcroForm.FormFields.First().Name;
if (resetAction != null)
{
    resetAction.Fields.Add(fieldNameToReset);
    resetAction.ResetFormType = ResetFormType.Include;
}
```
