Question

I have a listview with few items. I am using foreach loop to check if there is a match. The code I am using looks like this:

foreach (ListViewItem test in listView1.Items)
{
   if (test.SubItems[1].ToString() == item.SubItems[1].ToString())
   {
      test.Tag = item.Tag;
   }
}

What I am trying to do is, check the 2nd index and if there is a match replace the old item ‘test’ with the new one ‘item’.

Apparently there is no change in the listview. Is the way I am replacing the object wrong?

Answer 1

you can clone the item and assign directly to the list view item. but you need to change foreach loop to for loop.

for (int i = 0; i < listView1.Items.Count; i++)
{
    if (listView1.Items[i].SubItems[1].ToString() == item.SubItems[1].ToString())
    {
        listView1.Items[i] = (ListViewItem)item.Clone();
    }
}
