 In [WPF TreeViewAdv](https://help.syncfusion.com/wpf/classic/treeview/overview) to search and highlight the item, **Search** method has been implemented which is used to compare the search text with model items and highlighted the matched text in TextBlock inside the [TreeViewItemAdv](https://help.syncfusion.com/cr/wpf/Syncfusion.Windows.Tools.Controls.TreeViewItemAdv.html).
 
-``` c#
+```csharp
 if (mainitem != null && MatchSearchText(model.Header))
 {
     // Function which is used to apply inline to the TextBlock
     ApplyInline(mainitem, false);
 }
 ```
+
 Options like Search, FindPrevious, Find Next, SearchType (Contains, EndsWith, StartsWith options) has been used to match search text using ApplyInline method and apply the SearchBrush for highlighting the search text.
 
-``` c#
+```csharp
 if (!string.IsNullOrEmpty(tempSearchText))
 {
     if (this.SearchType == SearchType.StartsWith)
