Change item list

Question

How can I make it so that ListViews control the background color for elements, varying from element to element, for example, in WinAmp, as well as changing the colors of column headers?

If you look carefully, you will see that the first element is dark gray, and the second is black, etc.

Answer 1

You can set the property ListViewItem.BackColor, however, this must be done manually for each alternating line. Alternatively, you can use DataGridViewone that has a property AlternateRowStylethat will do this automatically - although you need to bind data to your rows in a collection, which is a whole different topic.

For a simple case:

foreach (ListViewItem item in listView1.Items)
{
    item.BackColor = item.Index % 2 == 0 ? Color.Red : Color.Black;
}

Answer 2

DrawItem DrawMode OwnerDrawVariable. DrawItemEventArgs BackColor, ( arg).

Answer 3

I suppose you add lines (subitems) in a loop? If so, use a loop counter to find out what color you want.

string[] strings = new string[]{"dild", "dingo"};
int i = 0;
foreach (var item in strings)
{
    Color color = i++ % 2 == 0 ? Color.LightBlue :  Color.LightCyan;
    ListViewItem lv = listView1.Items.Add(item);
    lv.SubItems[0].BackColor = color;
}

Answer 4

for (int index = 0; index <= ListView1.Items.Count; index++) 
{
    if (index % 2 == 0) 
    {
        ListView1.Items(index).BackColor = Color.LightGray;
    }

}

Answer 5

private static void RepaintListView(ListView lw)
{
    var colored = false;
    foreach (ListViewItem item in lw.Items)
    {
        item.BackColor = colored ? Color.LightBlue : Color.White;
        colored = !colored;
    }
}

You can call this method after adding an item. Or use it directly when adding
