                                ASPxGridView - How to implement showing/hiding columns in the manner similar to ASPxPivotGrid


                                The example demonstrates how to implement showing/hiding ASPxGridView columns in the manner similar to ASPxPivotGrid. To accomplish this, perform the following steps:

                                1. Place the ASPxPopupMenu control on a page. Add two items with such names as "HideColumn" and "ShowHideList".

                                2. Handle the client-side ASPxClientGridView.ContextMenu event. Show a popup menu if a user clicks on the grid's header.

                                3. Handle the client-side ASPxClientPopupMenu.ItemClick event. Check on which item the user has clicked and perform proper manipulations. If an item's name is "HideColumn", perform a grid's callback via the ASPxClientGridView.PerformCallback method and pass the required column name. In the ASPxGridView.CustomCallback event handler hide a column whose name we can get using e.Parameters. If an item's name is "ShowHideList", show or hide the grid's CustomizationWindow.
