Smita Set TreeView.TreeViewNodeSorter property to instance of IComparer class (which you might need to code yourself) and TreeView control will keep the nodes sorted at all times. Refer to MSDN article for details: http://msdn.microsoft.com/en-us/library/system.windows.forms.treeview.treeviewnodesorter.aspx If you're only storing strings to the TreeView then you can use already available StringComparer class to do the comparison so you need no coding at all. Refer to MSDN article for that too: http://msdn.microsoft.com/en-us/library/system.stringcomparer.aspx Zoran

Hi Just before loading the data to TreeView sort it. For moving the node You need to dynamically create drag & drop event for the node which is parent.
