 This section walks you through the UI customization options supported in the [SfPdfViewer](https://help.syncfusion.com/cr/maui/Syncfusion.Maui.PdfViewer.SfPdfViewer.html).
 
-## Customize the loading indicator
-
-You can customize the loading indicator’s properties by applying a style with the `TargetType` property to `ActivityIndicator`. You may also need to set the [ApplyToDerivedTypes](https://learn.microsoft.com/en-us/dotnet/maui/user-interface/styles/xaml?view=net-maui-7.0#apply-a-style-to-derived-types) property to `True` to get the style applied to the derived classes. See the following code example to customize the color of the loading indicator.
+## Customize the loading indicator 
+ 
+You can customize the loading indicator's color while loading the pdf and rendering the pages, merge the `SfPdfViewerTheme` key into application resources, you can customize the appearance of SfPdfViewer without merging common theme resource and control style resource dictionaries. Set the color of the loading indicator using the [Themes key for .NET MAUI PdfViewer](https://help.syncfusion.com/maui/themes/keys). Refer the code example below to disable the loading indicator.
