RadDatePicker SelectedDate from codebehind does not populate RadDateInput

I am trying to understand why the RadDatePicker will not populate the Input field with just calling the following statement in the PreRender method?

    
                protected void RadDatePickerStart_PreRender(object sender, EventArgs e) 
        
                { 
        
                    if (!RadDatePickerStart.SelectedDate.HasValue) 
        
                    { 
        
                        RadDatePickerStart.SelectedDate = DateTime.Today.AddDays(-1); 
        
                    } 
        
                }

For me to get the value to populate to the DatePicker textbox I have to add this assignment:

    
            RadDatePickerStart.DateInput.SelectedDate = DateTime.Today.AddDays(-1);

Can someone please explain why that is needed?

I have a RadComboBox and upon selection of its SelectedIndexChanged event method that works without even having to set the additional DateInput.SelectedDate as you can see in this little code snippet.

    
                protected void rcbDateRange_SelectedIndexChanged(object sender, EventArgs e) 
        
                { 
        
                    //Dates should be disabled unless Custom has been selected 
        
                    RadDatePickerStart.Enabled = false; 
        
                    RadDatePickerEnd.Enabled = false; 
        
                    switch (rcbDateRange.SelectedValue) 
        
                    { 
        
                        case "WeekSun": 
        
                            RadDatePickerStart.SelectedDate = DateTime.Today.AddDays(-5); 
        
                            RadDatePickerEnd.SelectedDate = DateTime.Today.AddDays(-1); 
        
                            break; 
        
                        case "custom": 
        
                            RadDatePickerStart.SelectedDate = DateTime.Today.AddDays(-1); 
        
                            RadDatePickerEnd.SelectedDate = DateTime.Today.AddDays(-1); 
        
                            RadDatePickerStart.Enabled = true; 
        
                            RadDatePickerEnd.Enabled = true; 
        
                            break; 
        
                        default: 
        
                            RadDatePickerStart.SelectedDate = DateTime.Today.AddDays(-1); 
        
                            RadDatePickerEnd.SelectedDate = DateTime.Today.AddDays(-1); 
        
                            break; 
        
                    } 
        
                }

I am not sure why you have to set the DateInput.SelectedDate in the PreRender to make it bubble up to the DatePicker's textbox.

I am using the SharedCalendar control and not sure if that makes a difference.

Just for completeness here is the aspx telerik elements:

    
                                  <telerik:RadComboBox ID="rcbDateRange" AllowCustomText="false" Skin="WebBlue" OnSelectedIndexChanged="rcbDateRange_SelectedIndexChanged"

RadScheduler and Events

For layout purposes I am trying to use the RadScheduler control in Sitefinity 4.0. I want to modify the template so that when it's clicked it goes to the event's home page. It seems that the event page in the events widget needs the DateCreated value. How can I cast an appointment object as an event object? I'm trying to do something to the effect of this:

Container doesn't exist. Is this even possible? Or the dataitem doesn't exist. Something gives me an object not set to instance error.

<telerik:RadScheduler runat="server" ID="Scheduler1" SelectedView="MonthView" height="100%" allowedit="false" allowdelete="false" allowinsert="false">
    <appointmenttemplate>
        <h6>
            <a href="<%=this.EventUrl %>
                <%#((Event)Container.Appointment.DataItem).DateCreated.Year.ToString() %>
                /<%#((Event)Container.Appointment.DataItem).DateCreated.Month.ToString() %>
                /<%#((Event)Container.Appointment.DataItem).DateCreated.Day.ToString() %>
                /<%#Eval("Subject").ToString().Replace(" ", "-").ToLower() %>">
                <%#Eval("Subject") %>
            </a>
        </h6>
    </appointmenttemplate>
</telerik:RadScheduler>

RadComboBox+RadTreeView item; server side - the combobox doesn't resize when tree expands

This is a follow up for

http://www.telerik.com/community/forums/aspnet-ajax/combobox/radcombobox-radtreeview-serverside.aspx

After applying the suggested workaround, I found that the combobox doesn't resize when tree nodes are expanded.
Instead, H/V scrolls are shown. Does someone know how to get rid of these scrolls and have the combo resizing when a
treenode expands?

Thanks,
Cris
