I use a number of telerik controls but for testing purposes i am trying to reskin a raddocking control. (Although i have test on gridviews/radpanes/toolbar e.t.c and nothing works.
No matter what theme i use , my visuals dont change. Am i missing something here ? Below is my xaml, i can change the theme to anything and its visual state doesnt change from its default behaviour.
I have all the theme references setup as well.
<telerik:RadDocking x:Name="Docking" Grid.Row="1" Grid.Column="0" Grid.ColumnSpan="3" ElementLoaded="Docking_ElementLoaded" PaneStateChange="Docking_PaneStateChange" telerik:StyleManager.Theme="Office_black">

In the XAML snippet you posted, there is a minor spelling mistake, the theme should read "Office_Black" with "B" being a capital letter. The more important thing, however, is that you are applying the default theme, which is by default already applied, so a visual change in the RadDocking control will not be observed.
Please, also verify that you have added assembly reference to each theme you wish to use. If you are still experiencing difficulties using any theme, please share more details on your scenario. It would be best if you could send a sample project duplicating the issue.

What telerik controls support themes ?
Grids/radpanes/raddocking/radtoolbar e.t.c ?
All RadControls are supported in our Theming mechanism, i.e. all RadControls use themes.
I attach here a very basic sample using the Vista theme.
If you still have difficulties working with themes, please, send us a sample reproducing your issue which we can test.

I do have another question though.
On my ribbon bar i have a theme selector combo (see below). This will then change my CurrentTheme property in my viewmodel. I then have my ribbon bar stylemanager set to bind to the currenttheme. This works in that it reskins the ribbon, however it doesnt reskin any of the menus/submenus/text on that ribbonbar. Do i need to somehow refresh its content ?
EDIT : The ribbonbar goes completely blacnk, if i minimise it and try to maximise it i get the following error
"
SCRIPT5022: Unhandled Error in Silverlight Application

Currently the ToggleTHeme command simply does
public void ToggleTheme(string theme)
{
this.CurrentTheme = ThemeManager.FromName(theme as string);
}
and my ribbonbar xaml
<telerik:RadRibbonBar ApplicationButtonVisibility="Collapsed" TitleBarVisibility="Collapsed" telerik:KeyTipService.IsKeyTipsEnabled="True" MinimizeButtonVisibility="Visible" telerik:StyleManager.Theme="{Binding CurrentTheme}">
a little more information about the problem here

would appreciate any help :)
This is a known issue in the ribbon implementation. Currently you can change the theme of the control in run-time from outside the control. Basically if you move the RadRibbonSplitButton with the Themes outside of the RadRibbonBar definition, the theme of the control will be properly changed.

Also, due to the many known limitations of the current implementation of the RadRibbonBar control, with the Q2 release of the RadControls for Silverlight and WPF we announced the new RadRibbonView control. It keeps the RibbonBar API but it significantly improves the design-time and databinding support of the control, as well as its functionality. In this blog post you can find more info about the differences between the two controls and a list of improvements that the RadRibbonView control brings to the "ribbon" UI.
Unfortunately the run-time theme change issue is not resolved in the RibbonView control as well, but it is logged in our PITS and we will do our best to fix it as soon as possible.
Moreover, please keep in mind that the RadContextMenu control is designed to behave as a ContextMenu that is opened on an element after a right-click action. And when it is used as a DropDownContent of a Button it might not behave properly. This is why we recommend using a RadMenu or a ListBox control to define a list of options inside the RadRibbonSplit/DropDownButtons.

I also see the same behaviors with docking controls, is that also a known issue ?
<telerik:RadComboBox x:Name="comboTheme" Visibility="Collapsed" SelectionChanged="comboTheme_SelectionChanged" SelectedIndex="0" HorizontalContentAlignment="Center" Width="150">
<telerik:Office_BlackTheme/>
<telerik:Office_BlueTheme/>
<telerik:Office_SilverTheme/>
<telerik:MetroTheme/>
<telerik:VistaTheme/>
<telerik:Windows7Theme/>
<telerik:SummerTheme/>
<telerik:Expression_DarkTheme/>
</telerik:RadComboBox>
<telerik:RadRibbonBar x:Name="RibbonBarControl" ApplicationButtonVisibility="Collapsed" TitleBarVisibility="Collapsed" telerik:KeyTipService.IsKeyTipsEnabled="True" MinimizeButtonVisibility="Visible" telerik:StyleManager.Theme="{Binding ElementName=comboTheme,Path=SelectedItem,Mode=TwoWay}">
<telerik:RadRibbonTab Header="Home">
Could you please check out our test project which demonstrates how the theme of RadRibbonBar and RadDocking is changed dynamically and let us know if we have missed something?
