u take one treeview and one [combobox](https://www.mindstick.com/articles/57/display-record-according-to-combobox-selection-in-csharp-dot-net) and [textbox](https://www.mindstick.com/articles/320/textbox-control-in-vb-dot-net) and 3 buttons . one [button](https://www.mindstick.com/articles/63/how-to-add-button-in-datagridview-in-csharp-dot-net) name is add parentnode ,[second](https://answers.mindstick.com/qa/41761/how-did-the-second-industrial-revolution-influence-women-s-roles-in-society) button name is addchildnode and third button name is deletenode button.\
if u enter the text in textbox .we [click](https://www.mindstick.com/articles/12423/social-login-magento-2-one-click-to-register-social) the [parent](https://www.mindstick.com/blog/154/how-to-find-parent-of-control-in-wpf) node or child node. that text will be added into the [treeview control](https://www.mindstick.com/articles/411/treeview-control-in-c-sharp-dot-net) and also saves in the combobox. like that if u [delete](https://www.mindstick.com/forum/33620/how-to-delete-record-from-list-in-mvc-using-ajax) the any parent node that time delete the parent and under child nodes and also at the same time removes the parentnode and uder childnodes removes the combobox.
