You can bind Workbook and Worksheet events using bind and unbind or unbindAll to unbind all the events. For example:
You can suspend Spread or a Sheet events using suspendEvent. Suspended events can be resumed using resumeEvent. This improved performance during long updates to Workbook content. For example:
<template>
<div class="sample-tutorial">
<gc-spread-sheets class="sample-spreadsheets" @workbookInitialized="initSpread">
<gc-worksheet></gc-worksheet>
<gc-worksheet></gc-worksheet>
<gc-worksheet></gc-worksheet>
</gc-spread-sheets>
<div class="options-container">
<div class="option-row">
<label>Click the sheet tab to change the active sheet. Click the cell or select range to edit.</label>
</div>
<div class="option-row">
<textarea id="showSpreadEvents" cols="40" rows="8" style="width: 90%" :value="eventLog"></textarea>
</div>
</div>
</div>
</template>
