+# highlight-nodes-on-search-treeview-xamarin
+
+You can highlight the TreeViewNode when searching in Xamarin.Forms SfTreeView. You can also refer to the search nodes in the SfTreeView document
+
+## Sample
+
+### XAML
+Bind the model property to customise the BackgroundColor of the ItemTemplate.
+```xaml
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+
+```
+
+### Behavior
+```csharp
+public class Behavior : Behavior
+{
+ SearchBar SearchBar;
+ SfTreeView TreeView;
+
+ protected override void OnAttachedTo(ContentPage bindable)
+ {
+ SearchBar = bindable.FindByName("searchBar");
+ TreeView = bindable.FindByName("treeView");
+
+ SearchBar.TextChanged += SearchBar_TextChanged;
+
+ base.OnAttachedTo(bindable);
+ }
+
+ private void SearchBar_TextChanged(object sender, TextChangedEventArgs e)
+ {
+ this.TraverseNodes(TreeView.Nodes, e.NewTextValue);
+ }
+
+ ///
+ /// Recursively traverse all the nodes in the TreeView and sets the BackgroundColor for the searched nodes.
+ ///
+ /// Represents the TreeViewNodes.
+ /// Represents the search key word.
+ private void TraverseNodes(TreeViewNodeCollection nodes, string searchText)
+ {
+ foreach (var child in nodes)
+ {
+ (child.Content as FileManager).NodeColor = (child.Content as FileManager).ItemName.ToLower().StartsWith(searchText.ToLower()) ? Color.Teal : Color.Transparent;
+
+ if (string.IsNullOrEmpty(searchText)) (child.Content as FileManager).NodeColor = Color.Transparent;
+
+ if (child.ChildNodes != null)
+ {
+ this.TraverseNodes(child.ChildNodes, searchText);
+ }
+ }
+ }
+}
+```
