I have a problem with ListView. I am trying to call AddToListView function which is in UCForm from MainForm but nothing shows up on the ListView. Strangely, when I call AddToListView on UCForm initialization everything works correctly. AddToListView function:

public void AddToListView()
{
    var item1 = new ListViewItem(new[] { "text1", "text2", "text3", "text4" });
    listView.Items.Add(item1);
}

Button click in MainForm:

UCForm uf = new UCForm();
private void btnAddToList_Click(object sender, EventArgs e)
{
     uf.AddToListView();
}

More info: There are 4 columns already set up. FullRowSelect is set to true. GridLines are set to true. What I've tried: Add item to ListView from another class and How to access a ListView control on another form.

Both of the posts didn't help me. My goal is to add values to ListView from another class.

If you have `UCForm` in the designer, then this `UCForm uf = new UCForm();` creates a different one. If so, you need to access the one in the designer. Like `UCForm1.AddToListView();`. – dr.null Apr 24 '21 at 15:45
What is UCForm? Can you post it too? – Serge Apr 24 '21 at 15:48
@Sergey it's a Form with a ListView and it also contains AddToListView function inside. – Anonymous-User Apr 24 '21 at 15:53
