Excel.BindingCollection class

Represents the collection of all the binding objects that are part of the workbook.

Extends

Remarks

[ API set: ExcelApi 1.1 ]

Properties

context

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

count

Returns the number of bindings in the collection.

items

Gets the loaded child items in this collection.

Methods

add(range, bindingType, id)

Add a new binding to a particular Range.

add(range, bindingTypeString, id)

Add a new binding to a particular Range.

addFromNamedItem(name, bindingType, id)

Add a new binding based on a named item in the workbook. If the named item references to multiple areas, the InvalidReference error will be returned.

addFromNamedItem(name, bindingTypeString, id)

Add a new binding based on a named item in the workbook. If the named item references to multiple areas, the InvalidReference error will be returned.

addFromSelection(bindingType, id)

Add a new binding based on the current selection. If the selection has multiple areas, the InvalidReference error will be returned.

addFromSelection(bindingTypeString, id)

Add a new binding based on the current selection. If the selection has multiple areas, the InvalidReference error will be returned.

getItem(id)

Gets a binding object by ID.

getItemAt(index)

Gets a binding object based on its position in the items array.

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