Excel.WorksheetCustomPropertyCollection class

Contains the collection of worksheet-level custom property.

Extends

Remarks

[ API set: ExcelApi 1.12 ]

Properties

context

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

items

Gets the loaded child items in this collection.

Methods

add(key, value)

Adds a new custom property that maps to the provided key. This overwrites existing custom properties with that key.

getCount()

Gets the number of custom properties on this worksheet.

getItem(key)

Gets a custom property object by its key, which is case-insensitive. Throws an error if the custom property does not exist.

getItemOrNullObject(key)

Gets a custom property object by its key, which is case-insensitive. If the custom property doesn't exist, then this method returns an object with its isNullObject property set to true. For further information, see *OrNullObject methods and properties.

load(options)

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

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 Excel.WorksheetCustomPropertyCollection object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.WorksheetCustomPropertyCollectionData) that contains an "items" array with shallow copies of any loaded properties from the collection's items.
