I have a listview with the columns Dealer, RecievedDate, ResolvedDate, Aging and Status(active and closed). I need to update all the rows that are still Active, where the Aging is the difference of the Current date and the RecievedDate every load of the form.

ListView? Which one? In .NET FCL, there are at least 3 classes under this simple name. Please, give us a full type name.

Are you serious? How else could you understand my question about ListView classes? I'm just curious.

Most of the times I've started out with a ListView, I've almost always reconsidered and went with a DataGridView instead. It can be customized to largely resemble a ListView, but has many more capabilities.

Right. As a rule of thumb, this is a better idea than ListView, in many cases.

stebo0728 gave you a pretty good idea. From your question, it looks like you want to use the View = System.Windows.Forms.View.Details.
In many cases, you can get much better results using System.Windows.Forms.DataGridView: https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridview%28v=vs.110%29.aspx[^].

You don't need to update the view; it is updated when you modify data, in this case, System.Windows.Forms.DataGridViewCell.Value property:
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.value(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.datagridviewcell.valuetype(v=vs.110).aspx[^].

Same thing goes with System.Windows.Forms.ListView. The view is changes when you modify ListViewItem or ListViewItem.ListViewSubItem. Please read the documentation carefully, including the code sample, and try it out:
https://msdn.microsoft.com/en-us/library/system.windows.forms.listview%28v=vs.110%29.aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.listviewitem(v=vs.110).aspx[^],
https://msdn.microsoft.com/en-us/library/system.windows.forms.listviewitem.listviewsubitem(v=vs.110).aspx[^].

If you are using the database, first of all, consider using binding. Please see:
