Hi, I'm looking to change the color aspect of some controls (upload, menu, window...) directly by program.
So I'm asking if there any way to change the skin parameters (color, fonts, dimensions ...) programmatically.

thank's

error in accesing child controls inside RadDock

I recently upgraded to prometheus, and my existing code which was working broke. Previously I used to access child controls inside raddock using code below

Label Label1 = (Label)RadDock2.FindControl("lblEvents");
Label1.Text = "my string here";

ASP.NET code

<telerik:RadDock ID="RadDock2" runat="server" Text="Events">
<ContentTemplate>
<asp:Label ID="lblEvents" runat="server"></asp:Label>
</ContentTemplate>
</telerik:RadDock>

Now, its throwing System.NullReferenceException at Label1.Text = "my string here";

Any help appreciated.
Thanks,
ABy

Visual problem with Menu on firefox 2.0

I am having a bit of a problem with the menu control when running on Firefox, The menu works fine, but the visuals are a bit messed up. It looks like the rignt gif of the menu item is aligning to the immediate right of the menu text, and not to the right side of the the actual menu item.

Is there a style element that I missed somewhere that fixes this?

Thanks
Lance

are there limitations in trial version radcontrols (treeview)?

I downloaded the trial version's radcontrols 'cause i need a treeview that works with several context menus, but i follow the steps describe at http://www.telerik.com/help/aspnet-ajax/tree_contextmenusdesign.html
Controls --> RadTreeview --> ContextMenus

i follow those steps, but i didn't write about that that namespace because would appear errors, i don't know, maybe this that example was created with VS 2003, so only i put the others steps only to get the contextmenu (appear), but anything happened. Actually in the RadContextMenu Item Builder dialog i created several menus and then i close the dialog box so i wanna try to see again those menus so i open the dialog box again and oh surprise theose ones don't appear there, but if i try to create one with the same name the next message is shown:
"There's other component with that name"

I was thinking that's 'cause the trial version

Refresh radScheduler

Hi.
I am showing a RadScheduler and on dropdown selection i want to refresh it.
Also when I move to another date and using the NavigationCommand event I call the refresh routine when I take the values from the dropdownlist and pass them to my Objectdatasource, in few words something like

    
            Dim curLogon As Logon = WebUtils.GetLogon(Me)  
        
            If Me.ddlMedicos.SelectedValue.Trim().Length > 0 Then  
        
             Dim arrString() As String = WebUtils.UnJoinCedula(Me.ddlMedicos.SelectedValue)  
        
              Me.RadSchedulerCita.DataSource = CitaMedicoList.List(curLogon,     
        
                                                       Me.ddlSucursal.SelectedValue,    
        
                                                  Me.ddlEspecialidad.SelectedValue, arrString(0),    
        
                                                arrString(1), Now())  
        
                 Me.RadSchedulerCita.Rebind()  
        
            End If

But the RadScheduler does not get refresh .... :-(

Any help ?

Viewstate and paging

I looked at your demo here...

http://www.telerik.com/demos/aspnet/Grid/Examples/Programming/ViewState/DefaultCS.aspx

And managed to get most of it working locally. The paging does work for me when I click on a number but it doesn't work when I click on either of the arrows. I noticed in your demo that when you mouseover the arrows you get...

__doPostBack.....

On mine I get......

default.aspx

My number links work correctly. What am I doing wrong that the arrows don't work?

Thanks.
