+# How to autofit item height based on content in WPF TreeView
+
+This repository describes how to autofit item height based on content in [WPF TreeView](https://www.syncfusion.com/wpf-controls/treeview) (SfTreeView)
+
+The `TreeView` allows adjusting height of items based on the content measured size while loaded by setting the `Height` argument with value returned from [QueryNodeSizeEventArgs.GetAutoFitNodeHeight](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeView.QueryNodeSizeEventArgs.html#Syncfusion_UI_Xaml_TreeView_QueryNodeSizeEventArgs_GetAutoFitNodeHeight) method.
+
+#### XAML
+
+``` xml
+<syncfusion:SfTreeView x:Name="sfTreeView"
+                       Margin="10"
+                       QueryNodeSize="SfTreeView_QueryNodeSize"    
+                       ExpandActionTrigger="Node"
+                       ItemsSource="{Binding Menu}" />
+```
+
+#### C#
+
+``` csharp
+sfTreeView.QueryNodeSize += SfTreeView_QueryNodeSize;
+
+private void SfTreeView_QueryNodeSize(object sender, Syncfusion.UI.Xaml.TreeView.QueryNodeSizeEventArgs e)
+{
+    if (e.Node.Level == 0)
+    {
+        //Returns specified item height for items.
+        e.Height = 30;
+        e.Handled = true;
+    }
+    else
+    {
+        // Returns item height based on the content loaded.
+        e.Height = e.GetAutoFitNodeHeight();
+        e.Handled = true;
+    }
+}
+```
