+# How to Drag and Drop Rows between WPF TreeGrid and WPF TreeViewAdv?
+
+This example illustrates how to drag and drop rows in between [WPF TreeGrid](https://www.syncfusion.com/wpf-controls/treegrid) (SfTreeGrid) and [WPF TreeViewAdv](https://help.syncfusion.com/wpf/classic/treeview/overview).
+
+You can drag and drop the items between TreeViewAdv and TreeGrid by wiring the [Drop](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridRowDragDropController.html#Syncfusion_UI_Xaml_TreeGrid_TreeGridRowDragDropController_Drop) and [DragStart](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridRowDragDropController.html#Syncfusion_UI_Xaml_TreeGrid_TreeGridRowDragDropController_DragStart) events from the [TreeGridRowDragDropController](https://help.syncfusion.com/cr/wpf/Syncfusion.UI.Xaml.TreeGrid.TreeGridRowDragDropController.html) class.

+        }
+        (AssociatedObject.treeview.ItemsSource as ObservableCollection<EmployeeInfo>).Remove(record as EmployeeInfo);
+    }
+}
+```
+
+In TreeViewAdv, you need to wire the Drop event,
+
+``` c#
+private void Treeview_Drop(object sender, DragEventArgs e)
+{
+    ObservableCollection<TreeNode> treeNodes = new ObservableCollection<TreeNode>();
+
+    if (e.Data.GetDataPresent("Nodes"))
+        treeNodes = e.Data.GetData("Nodes") as ObservableCollection<TreeNode>;
+
+    EmployeeInfo item = new EmployeeInfo();
+
+    if (treeNodes.Count == 0 || treeNodes == null)
+        return;
+
+    foreach (var node in treeNodes)
+    {
+        (AssociatedObject.sfTreeGrid.ItemsSource as ObservableCollection<EmployeeInfo>).Remove(node.Item as EmployeeInfo);
+    }
+}
+```
