How to Hide Other Month Cells in Month View
Environment
Product | Scheduler for Blazor |
Description
I need to hide the dates from other months in the Scheduler component's current month view because it may confuse the users.
Solution
To hide the dates from other months in the month view of the Scheduler component:
- Define
SlotTemplate
. - Use an
if
block to render conditionally the dates based on the selected month.
@using Telerik.SvgIcons

<div class="scheduler-set-item-template">S.Item: @(((Appointment)context).Title)</div>
