.NET Forum / Windows Forms / WinForm General / July 2006ListView exception
Hello, When i am trying to remove the last item in a listview: lstServers.Items.Remove(item); i get the exception: A first chance exception of type 'System.ArgumentOutOfRangeException' occurred in system.windows.forms.dll Additional information: Specified argument was out of the range of valid values. Does anyone know why that is? Thanx, Yael. What is the type of "item"? Is it an integer? You get this error if you try to access an item with an index that is larger then the iondex of the last item, for example if you have 5 items in the listbox then they have indexes 0 to 4, and you will get this error if try to acces an item using the value 5 as its index. To remove the last item, try lstServer.Items.remove(lstServer.Items.Count-1) Joris > Hello, > [quoted text clipped - 14 lines] > Thanx, > Yael. item is of type ListViewItem. The item is taken from the selectedItems, and the list view does remove it but it throws the exception. > What is the type of "item"?

It sounds like you have some kind of recurssive behavior going on that is causing it to try and remove it the first time but fails and when it tries again it does it, or even vice versa...
