Method Details
delete()
getRange()
Returns the range represented by the binding. Will throw an error if the binding is not of the correct type.
getRange(): Excel.Range;Returns
Remarks
Examples
await Excel.run(async (context) => {
const binding = context.workbook.bindings.getItemAt(0);
const range = binding.getRange();
range.load('cellCount');
await context.sync();
console.log(range.cellCount);
});
getTable()
Returns the table represented by the binding. Will throw an error if the binding is not of the correct type.
getTable(): Excel.Table;Returns
Remarks
Examples
await Excel.run(async (context) => {
const binding = context.workbook.bindings.getItemAt(0);
const table = binding.getTable();
table.load('name');
await context.sync();
console.log(table.name);
});
getText()
Returns the text represented by the binding. Will throw an error if the binding is not of the correct type.
getText(): OfficeExtension.ClientResult<string>;Returns
OfficeExtension.ClientResult<string>
Remarks
Examples
await Excel.run(async (context) => {
const binding = context.workbook.bindings.getItemAt(0);
const text = binding.getText();
binding.load('text');
await context.sync();
console.log(text);
});
load(options)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(options?: Excel.Interfaces.BindingLoadOptions): Excel.Binding;Parameters
Provides options for which properties of the object to load.
Returns
load(propertyNames)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNames?: string | string[]): Excel.Binding;Parameters
- propertyNames
-
string | string[]
A comma-delimited string or an array of strings that specify the properties to load.
Returns
Examples
await Excel.run(async (context) => {
const binding = context.workbook.bindings.getItemAt(0);
binding.load('type');
await context.sync();
console.log(binding.type);
});
load(propertyNamesAndPaths)
Queues up a command to load the specified properties of the object. You must call context.sync() before reading the properties.
load(propertyNamesAndPaths?: {
select?: string;
expand?: string;
}): Excel.Binding;Parameters
- propertyNamesAndPaths
-
{ select?: string; expand?: string; }
propertyNamesAndPaths.select is a comma-delimited string that specifies the properties to load, and propertyNamesAndPaths.expand is a comma-delimited string that specifies the navigation properties to load.
Returns
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.Binding object is an API object, the toJSON method returns a plain JavaScript object (typed as Excel.Interfaces.BindingData) that contains shallow copies of any loaded child properties from the original object.
toJSON(): Excel.Interfaces.BindingData;Returns
Event Details
onDataChanged
Occurs when data or formatting within the binding is changed.
readonly onDataChanged: OfficeExtension.EventHandlers<Excel.BindingDataChangedEventArgs>;Event Type
Remarks
Examples
// Link to full sample: https://raw.githubusercontent.com/OfficeDev/office-js-snippets/prod/samples/excel/30-events/data-changed.yaml
await Excel.run(async (context) => {
const sheet = context.workbook.worksheets.getItem("Sample");
const salesTable = sheet.tables.getItem("SalesTable");
const salesByQuarterBinding = context.workbook.bindings.add(salesTable.getRange(), "Table", "SalesByQuarter");
salesByQuarterBinding.onDataChanged.add(onSalesDataChanged);
console.log("The data changed handler is registered.");
await context.sync();
});
onSelectionChanged
Occurs when the selected content in the binding is changed.
Note*: If multiple, discontiguous cells are selected, Binding.onSelectionChanged only reports row and column information for one selection. Use Worksheet.onSelectionChanged for multiple selected ranges.
readonly onSelectionChanged: OfficeExtension.EventHandlers<Excel.BindingSelectionChangedEventArgs>;Event Type
