I dont think I saw something like this, i searched through net but all i could find is using foreach loop.

here I have the Listviews

What I wanted to do was If listview1 dont have any items named "Joshua", it will change listview2's "Joshua" from "Incomplete" to "Complete".

listview1 can have 2 or more "Joshua", so until all the "Joshua" are gone the listview2 must stay "Incomplete". when all the "Joshua" are gone in Listview1, thats when listview2's "joshua" be "Complete".

this must be the output.

I had put this in the timer1_tick since listview1 Items can be removed when time expires.(working and doing its job removing listview items that expires)

What I have tried:

I used for loop, but it doesnt change incomplete to complete. i think i might be wrong at the looping itself.

this is my code

for (int lst = 0; lst < listView2.Items.Count; lst++)
{
    for (int dgv = 0; dgv < dataGridView1.Rows.Count; dgv++)
    {
        if (listView2.Items[lst].SubItems[0].Text == listView1.Items[dgv].SubItems[0].Text )
        {
            continue;
        }
        else if (listView2.Items[lst].SubItems[0].Text != listView1.Items[dgv].SubItems[0].Text ) 
        {
            listView2.Items[lst].SubItems[1].Text = "Complete";
        }
    }
}
