c# - How can I set an icon for a ListViewSubItem?

Question

In a ListView you can have icons on each item.
When viewing in Details-mode, the icon is shown in the left-most column.

Can I show an icon in some other column?

Answer 1

The ListView control does not support images in sub-items natively. The easiest thing to do is switch to a DataGridView and use a DataGridViewImageColumn. If that is not possible, then you'll need to draw the icons yourself using the custom draw support in the ListView control. To do this set ListView.OwnerDraw = true and handle the ListView.DrawSubItem and ListView.DrawColumnHeader events.

private void listView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
{
    // Only interested in 2nd column.
    if (e.Header != this.columnHeader2)
    {
        e.DrawDefault = true;
        return;
    }

    e.DrawBackground();
    var imageRect = new Rectangle(e.Bounds.X, e.Bounds.Y, e.Bounds.Height, e.Bounds.Height);
    e.Graphics.DrawImage(SystemIcons.Information.ToBitmap(), imageRect);
}

private void listView1_DrawColumnHeader(object sender, DrawListViewColumnHeaderEventArgs e)
{
    e.DrawDefault = true;
}
