[Solved] Incorrect Appointment shown after clicking 24 hours button

Hi,

I experienced the above problem in my application and it also re-producable on the telerik demo page.

http://demos.telerik.com/aspnet-ajax/scheduler/examples/webservice/defaultcs.aspx

The followings are the steps to re-produce the issue.

1. Goto http://demos.telerik.com/aspnet-ajax/scheduler/examples/webservice/defaultcs.aspx

2. Create a appointment on an empty timeslot. (say. Thu 5, 10:00am )

3. Click the 24 hours link.

4. The appointment ( created in step 3 ) will be shown up in incorrect start time. ( It will shown up as Thu 5, 2:00 am)

Any workaround solution for it?

Thanks

Wilson

Not-allowed cursor not shown when dragging from grid to tree

The "not-allowed" cursor is not shown on tree nodes having property "allowDrop = false" when dragging from a RadGrid to a RadTreeView.
Is there any way that the "allowDrop" can work the same way as when dragging nodes inside the tree?

Also, when dragging a node to itself and the node is "allowDrop = false" the "not-allowed" cursor keeps showing on every mouseover (even when not dragging nodes).

Custom provider not working

Hi,

I've tried to implement a custom data provider with a database backend accessed through linq.

I've created the following base environment:

    
            Imports System  
        
            Imports System.Collections.Generic

                End Function 
        
            End Class

Then I created a new rad scheduler in a web page in the same project and wrote the following code in the loading event of the page

    
            Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                    If Not IsPostBack Then 
        
                        RadScheduler1.DataKeyField = "ID" 
        
                        RadScheduler1.DataStartField = "Start" 
        
                        RadScheduler1.DataEndField = "End" 
        
                        RadScheduler1.DataSubjectField = "Subject" 
        
                        RadScheduler1.DataRecurrenceField = "RecurrenceRule" 
        
                        RadScheduler1.DataRecurrenceParentKeyField = "RecurrenceParentID" 
        
                    End If 
        
                    Dim s As New MyDbSchedulerProvider  
        
                    RadScheduler1.DataSource = s  
        
                End Sub

When starting the apps throws an exception:
Data source is an invalid type. It must be either an IListSource, IEnumerable, or IDataSource.

I've been playing around with this for the last couple of hours but can't find a solution. I also tried to inherit from dbschedulerprovider but that didn't work as well.

When i change the loading event to

    
              Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load  
        
                    If Not IsPostBack Then 
        
                        RadScheduler1.DataKeyField = "ID" 
        
                        RadScheduler1.DataStartField = "Start" 
        
                        RadScheduler1.DataEndField = "End" 
        
                        RadScheduler1.DataSubjectField = "Subject" 
        
                        RadScheduler1.DataRecurrenceField = "RecurrenceRule" 
        
                        RadScheduler1.DataRecurrenceParentKeyField = "RecurrenceParentID" 
        
                    End If 
        
                    Dim s As New MyDbSchedulerProvider  
        
                    RadScheduler1.DataSource = s.GetAppointments(RadScheduler1)  
        
                End Sub

the scheduler diplays properly

Custom Command Question

Maybe I missed it somewhere but how do I/can I set the image of a custom command. When I've tried to add one to a RadDock all I can get to show up is the "gear" looking circle. For example, I would like to add a custom command for help. I would like this to show an image of a question mark "?".

Also when I add the commands using the following code from an example I found somewhere:

DockCommand command = new DockCommand();
command.AutoPostBack = true;
command.Name = "Command1";
dock.Commands.Add(command);

I lose the Minimize command that is there by default. I do have my RadDock's DefaultCommand set to ExpandCollapse.

Thanks!

ADO.NET Data Services question

Hi,

I have two entities, User and ContactDetails which are modelled using the Entity Framework. A single "user" record maps to a single "ContactDetails" record.

What I want to do is list various fields from the User and Contact details and show them in the grid, as this is a 1:1 link I need to show them one a single grid line.

In DataServices I can do this efficiently using something along the lines of "http://server/DataService.svc/UsernameSet?$expand=ContactDetails" which will return me what I need. However I cannot see how to do this with the grid control as I can only specify a single table name in the client settings.

Regards,

Richard
