+## Description
+
+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.
+
+## Solution
+
+To achieve clickable hyperlinks in Scheduler appointments, implement a method to automatically detect and convert plain URLs in the Description field into clickable links.
+
+1. Use the [`ItemTemplate`](slug:scheduler-templates-appointment) of the Scheduler to customize appointment rendering.
+2. Apply a helper method to parse the Description field and convert plain URLs to clickable links.
+
+Here’s an example:
+
+````Razor
+<TelerikScheduler Data="@Appointments" @bind-Date="@StartDate" @bind-View="@CurrView" Height="600px" Width="800px">
+    <ItemTemplate>
+        @{
+            var appointment = context as SchedulerAppointment;
+            var formattedDescription = ConvertUrlsToLinks(appointment.Description);
+        }
+        <div style="padding: 10px;" @onclick:stopPropagation>
+            @((MarkupString)formattedDescription)
+        </div>
+    </ItemTemplate>
+
+    <AllDayItemTemplate>
+        @{
+            var appointment = context as SchedulerAppointment;
+        }
+        @appointment.Title
+        <span>
+            Starts on @appointment.Start.Date.ToShortDateString()
+            ends on @appointment.End.Date.ToShortDateString()
+        </span>
+    </AllDayItemTemplate>
+
+    <SchedulerViews>
+        <SchedulerDayView StartTime="@DayStart" />
+        <SchedulerWeekView StartTime="@DayStart" />
+        <SchedulerMonthView>
+            <ItemTemplate>
+                @{
+                    var appointment = context as SchedulerAppointment;
+                    if (appointment.IsAllDay)
+                    {
+                        <span>@appointment.Title</span>
+                    }
+                    else
+                    {
+                        <div title="@appointment.Title" style="font-size: small">
+                            @appointment.Start.ToShortTimeString() to @appointment.End.ToShortTimeString()
+                        </div>
+                    }
+                }
+            </ItemTemplate>
+        </SchedulerMonthView>
+    </SchedulerViews>
+</TelerikScheduler>
