Many thanks

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  
        
            Imports System.Collections.Specialized

                    h.name = a.Subject

                    Dim resources As New List(Of Resource)()  
        
                    Dim db As New hoursDataContext

                    For Each T In tasks  
        
                        Dim r As New Resource  
        
                        r.Key = T.taskid  
        
                        r.Type = "Task" 
        
                        r.Text = T.name  
        
                        resources.Add(r)

                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

Combination of Tab Strip and Panel Bar Question

Hi

I am trying to get the functionality of a combined tab strip and panel bar, where I have a horizontal row of tab, but when they are click they act like a panel bar row, opening a layer vertically, so that more than one layer can be seen on the screen at the same time.

The full functionality I desire is shown here: http://www.talkfreelance.com/z_test/CS2/Images/layer_show_hide_with_tabs.gif

Can you advise if this is possible?

Thanks

[Solved] Treeview Load on demand & FindNodeByValue

Hello, I'm new user of Telerik and it's the first time I write a message here.

I have a RadTreeView which is loaded with "Load on demand" method (with SQL query) And I want to use a search field ID to expand the treeview on the result node.
I use the FindNodeByValue method (server-side) to do this but I have a problem.
When I click on the search button which fire this method, it return null value because it don't find de corresponding node.
but when I click after have expanded and collapsed nodes of the treeview, this method works well and I retrieve the good node by the value.

I understand that when I expand the nodes (manually with the mouse), they are loaded in memory and the method FindNodeByValue works but If I don't do this, it not works.

Thanks you very much for your help.

Info : I use ServerSideCallBack as expandmode
