The data specific to content controls of type 'ComboBox'.

Extends
OfficeExtension.ClientObject

Remarks

[ API set: WordApi BETA (PREVIEW ONLY) ]

Examples

// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/word/99-preview-apis/insert-and-change-combo-box-content-control.yaml

// Places a combo box content control at the end of the selection.
await Word.run(async (context) => {
  let selection = context.document.getSelection();
  selection.getRange(Word.RangeLocation.end).insertContentControl(Word.ContentControlType.comboBox);
  await context.sync();

  console.log("Combo box content control inserted at the end of the selection.");
});

Properties

context

The request context associated with the object. This connects the add-in's process to the Office host application's process.
listItems

Gets the collection of list items in the combo box content control.

Methods

addListItem(displayText, value, index)

Adds a new list item to this combo box content control and returns a Word.ContentControlListItem object.
deleteAllListItems()

Deletes all list items in this combo box content control.
load(propertyNames)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths)

Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
toJSON()

Overrides the JavaScript toJSON() method in order to provide more useful output when an API object is passed to JSON.stringify(). (JSON.stringify, in turn, calls the toJSON method of the object that is passed to it.) Whereas the original Word.ComboBoxContentControl object is an API object, the toJSON method returns a plain JavaScript object (typed as Word.Interfaces.ComboBoxContentControlData) that contains shallow copies of any loaded child properties from the original object.
track()

Track the object for automatic adjustment based on surrounding changes in the document. This call is a shorthand for context.trackedObjects.add(thisObject). If you're using this object across .sync calls and outside the sequential execution of a ".run" batch, and get an "InvalidObjectPath" error when setting a property or invoking a method on the object, you need to add the object to the tracked object collection when the object was first created. If this object is part of a collection, you should also track the parent collection.
untrack()

Release the memory associated with this object, if it has previously been tracked. This call is shorthand for context.trackedObjects.remove(thisObject). Having many tracked objects slows down the host application, so please remember to free any objects you add, once you're done using them. You'll need to call context.sync() before the memory release takes effect.
