History in ASP.NET MVC DOCX Editor
14 Aug 20261 minute to read
The ASP.NET MVC DOCX Editor (Document Editor) tracks the history of all editing actions done in the document, which allows undo and redo functionality.
Enable or disable history
Inject the EditorHistory module in your application to provide history preservation functionality for DocumentEditor.
@Html.EJS().DocumentEditor("container").IsReadOnly(false).EnableEditor(true).EnableSelection(true).EnableSfdtExport(true).Render()
<script>
var documenteditor;
document.addEventListener('DOMContentLoaded', function () {
documenteditor = document.getElementById("container").ej2_instances[0];
documenteditor.enableEditorHistory = true;
});
</script>You can enable or disable history preservation for a Document Editor instance at any time using the enableEditorHistory property.
editor.enableEditorHistory = false;Undo and redo
You can perform undo and redo by using the Ctrl+Z and Ctrl+Y keyboard shortcuts. The Document Editor exposes APIs to do it programmatically. To undo the last editing operation in the Document Editor, refer to the following sample code.
editor.editorHistory.undo();To redo the last undone action, refer to the following code example.
editor.editorHistory.redo();Stack size
The history of editing actions will be maintained in a stack, so that the last item will be reverted first. By default, the Document Editor limits the size of the undo and redo stacks to 500 each, respectively. However, you can customize this limit.
editor.editorHistory.undoLimit = 400;
editor.editorHistory.redoLimit = 400;
