+# How to drag and drop between two WinUI TreeView
+
+This example describes how to drag and drop between two [WinUI TreeView](https://www.syncfusion.com/winui-controls/treeview) (SfTreeView).
+
+You can customize the dragging operation between two treeview by using the [SfTreeView.ItemDragStarting](https://help.syncfusion.com/cr/winui/Syncfusion.UI.Xaml.TreeView.SfTreeView.html#Syncfusion_UI_Xaml_TreeView_SfTreeView_ItemDragStarting), [SfTreeView.ItemDropping](https://help.syncfusion.com/cr/winui/Syncfusion.UI.Xaml.TreeView.SfTreeView.html#Syncfusion_UI_Xaml_TreeView_SfTreeView_ItemDropping) and [SfTreeView.ItemDropped](https://help.syncfusion.com/cr/winui/Syncfusion.UI.Xaml.TreeView.SfTreeView.html#Syncfusion_UI_Xaml_TreeView_SfTreeView_ItemDropped) events.
