[Solved] collision detection and security

[Gompje]

Hi all,

I'm trying to see if I can use the planner for a project. But I cannot see how I can achieve the following:

• The user may not edit or change existing appointments, but is allowed to create new ones and change them.
• No double booking is allowed. eg no appointment on an already booked timeslot (collision)

For the first thing I found some threads on this forum, but it's not clear when  this will be included.

tx!

Hello Gompje,

Regarding the first requirement, the neatest solution would be the following:

1. Set AllowDelete="False"  and AllowEdit="False" for RadScheduler.
2. Use custom attributes to keep track of the user who created the appointment:

<telerik:RadScheduler ID="RadScheduler1" runat="server" CustomAttributeNames="CreatedBy" .../>

 protected void RadScheduler1_AppointmentInsert(object sender, SchedulerCancelEventArgs e)
    {
        e.Appointment.Attributes["CreatedBy"] = "currentUser";
    }

3. In the AppointmentCreated event check if the appointment was created by the current user and if yes, set the AllowEdit property to true:

protected void RadScheduler1_AppointmentCreated(object sender, AppointmentCreatedEventArgs e)
    {
        if (e.Appointment.Attributes["CreatedBy"] == "currentUser")
        {
            e.Appointment.AllowEdit = true;
        }
    }

As for the second question, please, refer to Limiting the number of simultaneous appointments online example.
