c# ListView sorting problem

I have a ListView which I can sort by clicking the columns. This works just fine. But I have a method which deletes a listview item and adds it again. After this the item is at the bottom and not at the same position as befor. I want it where it was. I tried it with lsvListView.Sort(); but its allways at the bottom..


I sort the columns with the ListViewColumnSorter class from Microsoft..

I'm sure I'm not getting something..
I have it like in the link for the columns clicks and it works..
but when I add a new list item it should automatically sort after the last sorting criteria..
private ListViewColumnSorter lvwColumnSorter;
 
this.lstvReports.ListViewItemSorter = lvwColumnSorter;
 
//Lists for faster filtering
lstvicOnlyErrors = new ListViewGroup();
lstvicAllReports = new ListViewGroup();
 
 
 
lstvicAllReports.Items.Add(lviReportItems);
 
lstvReports.Items.Clear();
lstvReports.Items.AddRange(lstvicAllReports.Items);
 
 
lstvReports.Sort();

Open in new window

I think I found the problem. When I click the standard column twice to sort it again then it works...
Just have to find out how to do it without that..

Somehow the lstvListview.Sort(); method doesn't know the standard sorting.. so when I start the app and I remove and add the ListviewItem it doesn't work. But when I first click a column to sort it, then it works.. Anybody know where to set this?

adding a item adds at the end, it does not "sort" automatically at the place according to the sorting.
so, after adding a new item, you have to sort explicitly once according to the sort you want.

I just did

            //Standart sort = Column 1
            lvwColumnSorter.SortColumn = 1;
            lvwColumnSorter.Order = SortOrder.Descending;


in the constructor

that does not sort implicitly.
as I said, after each new insert (or bulk of inserts), you need to call the sort() method explicitly.
