 ## Customize AI Response Rendering with ViewTemplateSelector in SfAIAssistView
+Use the [ViewTemplateSelector](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.Chat.SfAIAssistView.html#Syncfusion_UI_Xaml_Chat_SfAIAssistView_ViewTemplateSelector) property to assign a DataTemplateSelector that controls how messages (including AI responses) are rendered in SfAIAssistView. The selector can return different DataTemplates based on the message type or role (user/assistant/system), enabling rich presentations such as:
+- Markdown (via a Markdown viewer like MdXaml)
+- FlowDocument-based layouts
+- Images and custom visuals
+- HTML (via a WebBrowser control or third-party HTML renderer)
 
- ViewTemplateSelector allows you to control how AI responses are visually rendered in SfAIAssistView. By assigning a custom DataTemplate, you can format messages using markdown, HTML, or other visual layouts to enable rich, styled content in the message view.
