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,
Peter

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"

ResourceTypes
