private void ListView1_DrawColumnHeader(object sender, System.Windows.Forms.DrawListViewColumnHeaderEventArgs e) {
    e.DrawDefault = true;
}

private void ListView1_DrawSubItem(object sender, System.Windows.Forms.DrawListViewSubItemEventArgs e) {
    if (!(e.Item.SubItems(0) == e.SubItem)) {
        e.DrawDefault = false;
        e.DrawBackground();
        e.Graphics.DrawImage(My.Resources.Image1, e.SubItem.Bounds.Location);
        e.Graphics.DrawString(e.SubItem.Text, e.SubItem.Font, new SolidBrush(e.SubItem.ForeColor), (e.SubItem.Bounds.Location.X + My.Resources.Image1.Width), e.SubItem.Bounds.Location.Y);
    }
    else {
        e.DrawDefault = true;
    }
}

You can do this by implementing your own HttpHandler for the image. This is a .ashx file that implements the IHttpHandler interface.

So if you built one called ImageHandler you could use it declaratively in your ListView, something like this:

<asp:ListView 
     ID="ImageListView" 
     runat="server"
     DataKeyNames="Id">
        <ItemTemplate>        
            <img id="img1" src='<%#"~/ImageHandler.ashx?Id=" + Eval("Id") %>' />
        </ItemTemplate>
</asp:ListView>

ListView does not support this.

I found another answer, suggesting that you switch it with DataGridView.

How can I set an icon for a ListViewSubItem?

You could of course, do custom painting of the ListView if you wish, but I must say that things will get very complicated this way.
