I need to save and then restore listview columns settings (mainly column width and column order) when the user changes these settings:
1. How do I save and restore the columns width and order
2. Which event can I use to trap a user's column width and/or order change
I have not found a method like the save and restore layout of the radgridview ..
Thanks in advance

Hello Pierre-jean,
Thank you for contacting Telerik Support.
Our RadListView does not support save/load layout functionality similar to the one available for the RadGridView. However, you can handle the ListViewDetailColumn's width changes, by subscribing to the PropertyChanged event and using the following code:
As to the columns reordering, you can use the RadListView.Columns.CollectionChanged event in order to trace changes in columns order.
I hope this information helps. Should you have further questions, I would be glad to help.

Thanks with your help I managed to trap the events and write a save/restore function for the column widths.
However I have not found a solution to save and restore the columns order, this is however not really important to my application.

Hello Pierre-Jean,
Thank you for writing back.
It is possible to handle when columns are being reordered as well via the ColumnDragDropService:
Thus, you can implement the logic for saving columns order.
Please do not hesitate to contact us if you have any additional questions.

this.radListView1.ViewType = Telerik.WinControls.UI.ListViewType.DetailsView;DetailListViewElement el = this.radListView1.ListViewElement.ViewElement as DetailListViewElement;if (el != null){ el.ColumnDragDropService.PreviewDragDrop += ColumnDragDropService_PreviewDragDrop;}private void ColumnDragDropService_PreviewDragDrop(object sender, RadDropEventArgs e){ DetailListViewHeaderCellElement target = e.HitTarget as DetailListViewHeaderCellElement; DetailListViewHeaderCellElement drag = e.DragInstance as DetailListViewHeaderCellElement; if (target != null && drag != null) { ListViewDetailColumn targetColumn = target.Data; ListViewDetailColumn dragColumn = drag.Data; int targetColumnIndex = this.radListView1.Columns.IndexOf(targetColumn.Name); int dragColumnIndex = this.radListView1.Columns.IndexOf(dragColumn.Name); }}Thus, you can implement the logic for saving columns order.

I have tried using:
Private Sub lvEquip_ColumnWidthChanged(sender As Object, e As PropertyChangedEventArgs) If e.PropertyName = "Width" Then Dim Ini As New IniFile(GetAppDataPath() & "\dat.ini") For I As Integer = 0 To lvEquip.Columns.Count - 1 Ini.PutVar("Settings", "ColSize_Equip_" & I, lvEquip.Columns(I).Width) Settings.ColSize_Equip(I) = lvEquip.Columns(I).Width Next End IfEnd Sub
With:
AddHandler lvEquip.Columns.PropertyChanged, AddressOf lvEquip_ColumnWidthChanged
^^ In the load event. It does not capture when the width of a column is changed. I set a breakpoint directly on [If e.PropertyName = "Width" Then] and it never gets hit. What am I missing?

Hello, Brandon,
If you want to detect when a column's width in RadListView is changed, it is necessary to iterate the Columns collection and subscribe to the PropertyChanged event for each ListViewDetailColumn:
