How to Disable Header and Footer Editing in ASP.NET Core DOCX Editor

27 Aug 20265 minutes to read

You can use the [restrictEditing] property to disable header and footer editing based on selection context type.

RestrictEditing allows you to restrict the document modification and makes the document read-only mode. So, by using this property, and if the selection is inside header or footer, you can set this property as true.

The following example code illustrates how to disable header and footer edit in the DocumentEditorContainer instance.

<ejs-documenteditorcontainer id="container" serviceUrl="/api/DocumentEditor/" enableToolbar=true created="onCreated" .selectionChange="onSelectionChanged" height="590px"></ejs-documenteditorcontainer>

<script>
    var documenteditor;
    var container;
    function onCreated() {
        var documenteditorElement = document.getElementById("container");
        container = documenteditorElement.ej2_instances[0];
    }
    function onSelectionChanged() {
        // Check whether selection is in header
        if (container.documentEditor.selection.contextType.indexOf('Header') > -1 ||
        // Check whether selection is in Footer
          container.documentEditor.selection.contextType.indexOf('Footer') > -1) {
          // Change the document to read only mode
          container.restrictEditing = true;
        } else {
          // Change the document to editable mode
          container.restrictEditing = false;
        }
    }
</script>

Otherwise, you can disable clicking inside Header or Footer by using the [closeHeaderFooter] API in the selection module.

The following example code illustrates how to close header and footer when the selection is inside header or footer in the DocumentEditorContainer instance.

<ejs-documenteditorcontainer id="container" serviceUrl="/api/DocumentEditor/" enableToolbar=true created="onCreated" selectionChange="onSelectionChanged" height="590px"></ejs-documenteditorcontainer>

<script>
    var documenteditor;
    var container;
    function onCreated() {
        var documenteditorElement = document.getElementById("container");
        container = documenteditorElement.ej2_instances[0];
    }
    function onSelectionChanged() {
        // Check whether selection is in header
        if (container.documentEditor.selection.contextType.indexOf('Header') > -1 ||
        // Check whether selection is in Footer
          container.documentEditor.selection.contextType.indexOf('Footer') > -1) {
          // Close header Footer
          container.documentEditor.selection.closeHeaderFooter();
        }
    }
</script>

Like restrictEditing, you can use the [isReadOnly] property in the DOCX Editor to disable header and footer edit.

The following example code illustrates how to disable header and footer edit in the DocumentEditor instance.

<ejs-documenteditor isReadOnly=false id="container" selectionChange="onSelectionChanged"></ejs-documenteditor>

<script>
    var documentEditor;
    document.addEventListener('DOMContentLoaded', function () {
        documentEditor = document.getElementById("container").ej2_instances[0];
        documentEditor.enableAllModules();
    });
    function onSelectionChanged() {
        // Check whether selection is in header
        if (documentEditor.selection.contextType.indexOf('Header') > -1 ||
          // Check whether selection is in Footer
          documentEditor.selection.contextType.indexOf('Footer') > -1) {
          // Change the document to read only mode
          documentEditor.isReadOnly = true;
        } else {
          // Change the document to editable mode
          documentEditor.isReadOnly = false;
        }
    }
</script>
