Hello Kasi,

One possible solution is to customize the advanced form as you want.
Please, take a look at our Advanced Template Demo where you can customize your form as you want. In your case you can put RequiredFieldValidators like it is done for the Subject field.

Another way is to validate on Insert/Update event like here:

protected void RadScheduler1_AppointmentInsert(object sender, AppointmentInsertEventArgs e)
   {
       String csname1 = "PopupScript";
       Type cstype = this.GetType();
       // Get a ClientScriptManager reference from the Page class.
       ClientScriptManager cs = Page.ClientScript;
       // Check to see if the startup script is already registered.
       if (String.IsNullOrEmpty(e.Appointment.Description))
       {
           String cstext1 = "alert('The duration field should not be empty!');";
           cs.RegisterStartupScript(cstype, csname1, cstext1, true);
           e.Cancel = true;
       }
   }
   protected void RadScheduler1_AppointmentUpdate(object sender, AppointmentUpdateEventArgs e)
   {
       String csname1 = "PopupScript";
       Type cstype = this.GetType();
       // Get a ClientScriptManager reference from the Page class.
       ClientScriptManager cs = Page.ClientScript;
       // Check to see if the startup script is already registered.
       if (String.IsNullOrEmpty(e.Appointment.Description))
       {
           String cstext1 = "alert('The duration field should not be empty!');";
           cs.RegisterStartupScript(cstype, csname1, cstext1, true);
           e.Cancel = true;
       }
   }

You can also look at this KB article to see how to accomplish this client side.

Hope this will helps
