| 23 | +## Description |
| 24 | + |
| 25 | +I want to add clickable hyperlinks in Scheduler appointments. Including plain URLs in the Description field without having to write full `<a>` tags would be good. |
| 26 | + |
| 27 | +## Solution |
| 28 | + |
| 29 | +To achieve clickable hyperlinks in Scheduler appointments, implement a method to automatically detect and convert plain URLs in the Description field into clickable links. |
| 30 | + |
| 31 | +1. Use the [`ItemTemplate`](slug:scheduler-templates-appointment) of the Scheduler to customize appointment rendering. |
| 32 | +2. Apply a helper method to parse the Description field and convert plain URLs to clickable links. |
| 33 | + |
| 34 | +Here’s an example: |
| 35 | + |
| 36 | +````Razor |
| 37 | +<TelerikScheduler Data="@Appointments" @bind-Date="@StartDate" @bind-View="@CurrView" Height="600px" Width="800px"> |
| 38 | + <ItemTemplate> |
| 39 | + @{ |
| 40 | + var appointment = context as SchedulerAppointment; |
| 41 | + var formattedDescription = ConvertUrlsToLinks(appointment.Description); |
| 42 | + } |
| 43 | + <div style="padding: 10px;" @onclick:stopPropagation> |
| 44 | + @((MarkupString)formattedDescription) |
| 45 | + </div> |
| 46 | + </ItemTemplate> |
| 47 | +
|
| 48 | + <AllDayItemTemplate> |
| 49 | + @{ |
| 50 | + var appointment = context as SchedulerAppointment; |
| 51 | + } |
| 52 | + @appointment.Title |
| 53 | + <span> |
| 54 | + Starts on @appointment.Start.Date.ToShortDateString() |
| 55 | + ends on @appointment.End.Date.ToShortDateString() |
| 56 | + </span> |
| 57 | + </AllDayItemTemplate> |
| 58 | +
|
| 59 | + <SchedulerViews> |
| 60 | + <SchedulerDayView StartTime="@DayStart" /> |
| 61 | + <SchedulerWeekView StartTime="@DayStart" /> |
| 62 | + <SchedulerMonthView> |
| 63 | + <ItemTemplate> |
| 64 | + @{ |
| 65 | + var appointment = context as SchedulerAppointment; |
| 66 | + if (appointment.IsAllDay) |
| 67 | + { |
| 68 | + <span>@appointment.Title</span> |
| 69 | + } |
| 70 | + else |
| 71 | + { |
| 72 | + <div title="@appointment.Title" style="font-size: small"> |
| 73 | + @appointment.Start.ToShortTimeString() to @appointment.End.ToShortTimeString() |
| 74 | + </div> |
| 75 | + } |
| 76 | + } |
| 77 | + </ItemTemplate> |
| 78 | + </SchedulerMonthView> |
| 79 | + </SchedulerViews> |
| 80 | +</TelerikScheduler> |
| 81 | +
|

| 136 | + }); |
| 137 | + } |
