Hi!
I'm using the radscheduler with a custom advanced form.
Both the advanced form and the page containing it have EnableViewState to true but I'm still having post back issues.
When a control in the advanced form fires a postback, all data binded to the advanced form is cleared and the state of the controls are reset.

How do you prevent this?
thanks!

Hello Emilie,

How exactly do you implement your custom advanced form for RadScheduler? You can download a sample from here and test it by adding a postback button in AdvancedForm.ascx:

http://www.telerik.com/support/kb/aspnet-ajax/scheduler/sample-project-of-the-customizing-the-advanced-template-example.aspx

The controls in the advanced from should persist their state.


Best wishes,

Hum I downloaded the examples but to be honest, there's just so much stuff in those pages with all the panels that I can't make head and tails out of it.
Do you have any simpler example package (basic)?


We simply declared the scheduler like this :

<telerik:RadScheduler runat="server" ID="eventScheduler" 
            Width="850px" Height="100%" 
            OnAppointmentInsert="eventScheduler_AppointmentInsert" 
            OnAppointmentUpdate="eventScheduler_AppointmentUpdate" 
            OnAppointmentDelete="eventScheduler_AppointmentDelete" 
            DataKeyField="ID"  
            DataSubjectField="Subject"  
            DataStartField="Start"  
            DataEndField="End" 
            StartInsertingInAdvancedForm="true" 
            StartEditingInAdvancedForm="true" 
            OnAppointmentDataBound ="eventScheduler_AppointmentDataBound" 
            > 
    
      <AdvancedEditTemplate> 
            <uc1:AdvancedForm runat="server" EnableViewState="true" ID="AdvancedEditForm" 
                                        Subject='<%# Bind("Subject") %>' 
                                        Start='<%# Bind("Start") %>' 
                                        End='<%# Bind("End") %>'/> 
            </AdvancedEditTemplate> 
            <AdvancedInsertTemplate> 
            <uc1:AdvancedForm runat="server" ID="AdvancedInsertForm" 
                                        Subject='<%# Bind("Subject") %>' 
                                        Start='<%# Bind("Start") %>' 
                                        End='<%# Bind("End") %>'/> 
            </AdvancedInsertTemplate> 
    </telerik:RadScheduler>

Hello Emilie,

We don't have anything simpler from the demo for Q3 2009 from the kb article(SchedulerCustomAdvancedFormQ3_2009.zip)

If you need help with anything specific related to this demo, we will be glad to assist you.


All the best,

Hello Rob,

We have simplified the advanced templates since 2009. Do you use the user controls from the latest version of the Advanced Templates demo.

Hi,

is the problem already fixed? I have the problem with the latest version of Radscheduler, I have some serverside events for my radcomboboxes on the form and after autopostback nothing is repopulated and the controls are empty.

Hello,

Could you please clarify whether you are experiencing the described problem with our latest version of the Advanced Templates demo.Please watch here that demo project when the "Room" RadComboBox  is subscribed for SelectedIndexChaged server-side event and a label control to print the selected item. All existing data on the form is persisted and the RadComboBox control is repopulated. Please clarify if there is different in your project and how we can replicate the issue that you are facing.
Please find here a runnable project that contains a user control representing the RadScheduler advanced form.

Regards,
Boyan Dimitrov

Hi,

 

I'm having the same problem, I tried to add ressource combo to implement cascading dropdown.

But when I change the first combo no event is triggered to filter the second one.

I can't figure out how to implement this.

Could you help me.

Regards

Hello Davy,

For the Cascading ComboBoxes functionality in the Advanced form I would recommend reviewing the Implement related RadComboBox controls in the advanced form Code Library and the RadScheduler Resource Type Cascading Dropdown forum thread. 

If that does not help, I would like to ask you to modify the provided code library so that it implements your case or prepare a runnable sample project and send it to us in an official support ticket.

Regards,
