So how can I use the wpf themes such as Onyx, Office2kBlack, LunaSilver, etc on the shared controls? More importantly use the current theme (Infragistics.Windows.Themes.ThemeManager.CurrentTheme) which is just a string. My app allows users to pick the theme via drop down box. When user selects a different Theme I set the Infragistics.Windows.Themes.ThemeManager.CurrentTheme property and whole app changes. With the shared controls seems that this is not possible. The solution you provided is hard coded.

I tried this but did not work:

ResourceDictionary dic = Infragistics.Windows.Themes.ThemeManager.GetResourceSet(Infragistics.Windows.Themes.ThemeManager.CurrentTheme, "Editors");
if (dic != null)
{
xamComboEditorType.Resources.MergedDictionaries.Add(dic);
}

Thanks

Hello, 

As the XamComboEditor you are using is a shared control and in Silverlight themes are not supported even though you are using WPF the Theme property could not be set. You could still use a theme for the editor by adding it as ResourceDictionary:

<ResourceDictionary>

            <ResourceDictionary.MergedDictionaries>

                <igThemes:ResourceWasher>

                    <igThemes:ResourceWasher.SourceDictionary>

                        <ResourceDictionary Source="Themes/Metro.xamComboEditor.xaml" />

                    </igThemes:ResourceWasher.SourceDictionary>

                </igThemes:ResourceWasher>

            </ResourceDictionary.MergedDictionaries>

        </ResourceDictionary>

I have modified the project in order to apply the Metro theme.

If you have any other questions on the matter, please do not hesitate to ask.

I found the problem. The namespace I was using was http://schemas.infragistics.com/xaml/wpf instead of http://schemas.infragistics.com/xaml.

But now that control does not have Theme property. I use that to set to current theme of application ie: Theme="[current]". How do I do this with the shared controls?

Well I think the issue is that I also have InfragisticsWPF4.Editors.v12.2.dll reference since I am using xamDataGrid. Also in the help under General Concepts->Assemblies->NetAdvantage Assemblies that dll is listed as deprecated but it is listed as a dependent of InfragisticsWPF4.DataPresenter.v12.2.dll. Which is not deprecated.
