Hi Somanna,

Thank you for posting to Infragistics Community!

I have been looking into your question and you are correct that styling the Infragistics.Controls.Editors.XamComboEditor based on any of the predefined themes would not be as straightforward as the Infragistics.Windows.Editors one, however, it is still possible. Hence, I am wondering if your question is about the approach to achieve this?

Assuming this is the case, and that the target theme would be RoyalLight, I will describe the approach to add a custom style to the Infragistics.Controls.Editors.XamComboEditor based on this theme.

It involves copying the RoyalLight.xamComboEditor.xaml and its dependent files (RoyalLight.Styles.xaml and RoyalLight.Theme.Colors.xaml) from the Infragistics DefaultStyles directory to your app. They can be found under:

C:\Program Files (x86)\Infragistics\*your version*\WPF\Themes\ RoyalLight

Once the relevant files are included, they can be merged in a ResourceDictionary and the custom style can be based on the corresponding RoyalLight one:

<Window.Resources>
        <ResourceDictionary>
            <ResourceDictionary.MergedDictionaries>
                <ResourceDictionary Source=" RoyalLight.xamComboEditor.xaml" />
            </ResourceDictionary.MergedDictionaries>
            <Style TargetType="{x:Type ig:XamComboEditor}"
                   BasedOn="{StaticResource XamComboEditorStyle}">
                <Style.Setters>
                    <Setter Property="Background"
                            Value="#FFFBC6C6" />
                </Style.Setters>
            </Style>
            <local:DataUtil x:Key="DataUtil" />
        </ResourceDictionary>
    </Window.Resources>

Attached you will find a sample demonstrating this. Please, test it on your side and if you require any further assistance on the matter, please let me know.

The default styles are saved in the mentioned directory when installing the product with the installer. However, as of the latest version 23.2 and as per our documentation here, the Infragistics traditional installer has been removed, and so the WPF controls are now supported exclusively through NuGet moving forward. So, I assume your app is using the NuGet packages in this case, isn’t it?

Anyways, it is still possible to download these resources, as they are needed for scenarios such as the current. They can be found on the Customer Portal, under downloads. Under the WPF Product section you will find a bundle named “Ultimate UI for WPF 2023 Vol. 2 Product And Samples”. This will download an archive containing three installers. The one you need is named “Infragistics_WPF_20232”. After running it, the Default Styles directory should be under the following path, as mentioned: C:\Program Files (x86)\Infragistics\2023.2\WPF\DefaultStyles.

Just for the sake of the demo, I am also attaching a sample with the same code for styling the XamComboEditor (input), only in a project targeting .NET 6 and having the 23.2 latest release of Ultimate UI for WPF Trial installed as a NuGet package. As you will see, the result is the same.

If you require any further information, please, let me know.

Best regards,
