Checkboxes

  • 2 minutes to read

The RichEditControl allows you to view and export a document containing checkbox form fields. These form fields are interactive, so end-users can toggle their state as needed. The resulting document can be exported to PDF or HTML format.

IMPORTANT

Currently, RichEditControl supports only checkbox form fields. ActiveX and form control checkboxes are not supported.

RichEditControl does not support using checkboxes in OpenDocument Text (.odt) and HTML documents.

Checkboxes in API

Use members from the table below to manage checkboxes in code.

An FormFieldIncorrectSubDocumentException occurs on attempt to insert the checkbox into a comment, header, footer or text box.

FormField.Name

Specifies a bookmark name associated with the checkbox.

CheckBox.State

CheckBox.SizeMode

Defines the checkbox's size mode. Use the CheckBox.Size property to specify the exact size.

FormField.HelpTextType

FormField.StatusTextType

Specifies the type of instructional text that accompanies the checkbox.

FormField.HelpText

FormField.StatusText

Gets or sets the checkbox's instructional text. With the ...TextType property set to FormFieldTextType.Auto, make sure that the ...Text property value is equal to one of the document's AutoText gallery entries.

A complete sample project is available at https://github.com/DevExpress-Examples/wpf-richedit-document-api-t213968.

DocumentPosition currentPosition = document.CaretPosition;
DevExpress.XtraRichEdit.API.Native.CheckBox checkBox = document.FormFields.InsertCheckBox(currentPosition);
checkBox.Name = "check1";
checkBox.State = CheckBoxState.Checked;
checkBox.SizeMode = CheckBoxSizeMode.Auto;
checkBox.HelpTextType = FormFieldTextType.Custom;

Checkboxes in the User Interface

End-users can change the checkbox's state by double-clicking the object. The state defined by an end-user is passed to the CheckBox.DefaultState property.

RichEditControl has the following limitations when working with checkboxes in the UI:

  • It does not provide user interface elements to manage checkboxes.
  • It cannot display instructional text provided for the checkbox.
  • It does not support macros assigned with the checkbox.
