Question

I am currently trying to grab all the subitems from one column from every checked listviewitem, and display them in the richtextbox, but I am not sure how to do it. This is my current code.

I am also trying to do this in the ItemChecked Event.

        foreach (ListViewItem item in listView1.Items)
        {
            if (listView1.CheckedItems.Count > 0)
            {
                richTextBox2.Text = listView1.CheckedItems[0].SubItems[1].Text;

            }
        }

I thought this would work but apparently not. All help is appreciated!

Answer 1

You are replacing the content of the textbox in each loop. Try appending the text with +=. You also need to pick the correct item

richTextBox2.Text = String.Empty;
foreach (ListViewItem item in listView1.Items)
{
    if (item.Checked)
    {
        richTextBox2.Text += item.SubItems[1].Text + Environment.NewLine;
    }
}

You could also write this with a LINQ expression and String.Join

richTextBox2.Text = String.Join(Environment.NewLine,
    from item in listView1.Items.OfType<ListViewItem>()
    where item.Checked
    select item.SubItems[1].Text);
