RadScheduler Resource Type Cascading Dropdown

[Ayub]

How do you create cascading Dropdown for Resource Type. We have two resources added to appoint. Class and teacher. We want during time of creation of appointment. When user selects class. The teacher drop down should filter the data and show only teacher for that class. We are using Linqdatasource

question 1: For teacher Linqsource how can we pass parameter as class dropdown control value.
question 2: How can we define on selected index change event for dropdown class.
question 3: How can you make teacher dropdown invisible as default. and make it visible on selected index change event of Class dropdown.

This solution is for Q3 2008. We are using Q2 2008. Need a solution example for Q2 2008

[Ayub]

We are trying to use the advance form example in Q2 Live demo folder scheduler example. We copied DefaultTemplates but we are getting all sort of error related to telerik.Quick start and already defined attributes error. Do you have any working Q2 2008 advance form example

[Ayub]

Ok the example link given above. After lot of struggle we were able to make the Code work. We are using two dropdowns in Custome Attributes as shown in example. But the Selected index change is not working. On selected index change the form is posted back and all the data is lost.

Can you provide working selected index change event for given example.

Secondly in all the examples for User and room the data source is XML file. Do we have any User and Room example which uses Linq as datasource.

Hello Ayub,

I am not sure why you experience this problem at your end. If you can send us a workig project demonstrating the issue, we will be able to tell what the problem is. To be able to attach files, you need to open a support ticket.

As for the other question, here is a LINQ data source online demo with RadScheduler:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/linqdatasource/defaultcs.aspx

Also, there is a kb article with LINQ:

Peter,

The link you posted (http://www.telerik.com/support/kb/aspnet-ajax/scheduler/implement-related-dropdownlist-controls-in-the-advanced-form.aspx) is dead.

Do you have and example that could help me to apply styles dynamically to a Scheduler event? I wrote the following code but the scheduler just ignores it and the style isn't applied:

@Page_PreRender:

...         Scheduler1.DataSource = userEvents;         Scheduler1.DataBind();         foreach (var eventTypes in events.sp_Select_EventTypesByOrgID(orgId))

{

string color = eventTypes.Color;

string absencetype = eventTypes.AbsenceType;

RadScheduler1.Resources.Add(new Resource("EventType", eventTypes.EventTypeID, eventTypes.EventType.Trim()));

RadScheduler1.ResourceStyles.Add(new ResourceStyleMapping("Calendar", eventtype, "rsCategory" + color.Trim()));

}

I have a column named Color and it is being correctely populated so it is matching Telerik's (16) styles. I even tried applying styles during the Databound but it didn't work as well:

@RadScheduler1_AppointmentDataBound:

 

        if (e.Appointment.Resources.GetResourceByType("Calendar") != null )
        {
            string eventType = e.Appointment.Resources[0].Text.Trim();
            if (eventType != null)
            {
                switch (eventType)
                {
                    case "Meeting":
                        e.Appointment.CssClass = "rsCategoryOrange";
                        break;
                    /// more here
                    default:
                        e.Appointment.CssClass = "rsCategoryBlue";
                        break;
                }
            }

I noticed that (e.Appointment.Resources.GetResourceByType("Calendar") is always null.

It works thou if I hardcode the styles to the HTML but it crashes if my Org passes an event not coded there.

Maybe I'm applying the styles at a wrong place... any clue?

Thanks!
Gilberto

Hello Gilberto,

The kb article you refer to has been updated and its url has changed (aplogies for this). Here is the correct url in case you need it for reference:
http://www.telerik.com/support/kb/aspnet-ajax/scheduler/implement-related-radcombobox-controls-in-the-advanced-form.aspx

As for the other issue, I am not sure why you need to handle Page_PreRender, but this event might be too late for the styles to be applied and to declare resources. Can you move your logic in Page_Init or  Page_Load instead.

Alternatively, you can declare resource style mapping inline as in this demo:
http://demos.telerik.com/aspnet-ajax/scheduler/examples/resourceavailability/defaultcs.aspx

<ResourceStyles>
             <telerik:ResourceStyleMapping Type="User" Text="Alex" ApplyCssClass="rsCategoryBlue" />
             <telerik:ResourceStyleMapping Type="User" Text="Bob" ApplyCssClass="rsCategoryOrange" />
             <telerik:ResourceStyleMapping Type="User" Text="Charlie" ApplyCssClass="rsCategoryGreen" />
         </ResourceStyles>

All the best,

I have the same issue as above.  Has there been a solution to the above thread? Please provide an example for me to follow.

Hi Kevin,

What is the exact problem that you experience?
Do you want to apply styles dynamically to RadScheduler or something different?

Kind regards,

I created dropdowns using resource type in the Radscheduler.  This is the event I want to happen.  When selecting from the first dropdown, the value which I selected determines what will be populated on the second dropdown.  When selecting from the second dropdown, the value selected will determine the populating of the third dropdown and so on.  I guess they call that Radscheduler resource type cascading dropdown.  Can I accomplish this?  I don't see any of your demo for the radscheduler that has this feature.  What I see is single data source dropdown, no cascading.
This is what I did and can't cascade.

 

 

ResourceTypes

 

 

 

telerik:ResourceType DataSourceID="SqlDataSource2" ForeignKeyField="Programs"

 

 

 

KeyField="Description" Name="ProgramType" TextField="Description"

 

 

 

telerik:ResourceType DataSourceID="SqlDataSource1" ForeignKeyField="Users"

 

 

 

KeyField="Full_Name" Name="All_Users" TextField="Full_Name"

 

 

 

telerik:ResourceType DataSourceID="SqlDataSource3" ForeignKeyField="ROOMS"

 

 

 

KeyField="ROOMNAME" Name="NameOfRoom" TextField="ROOMNAME"

Hi Kevin,

Have you tried the approach used in this kb article -
http://www.telerik.com/support/kb/aspnet-ajax/scheduler/implement-related-radcombobox-controls-in-the-advanced-form.aspx?

Note that you need to use custom attributes instead of resources to achieve the related comboboxes functionality.
