Winforms - How to alternate the color of strings in a ListView control?

Question

Using C # Winforms (3.5).

Is it possible to set the colors of the lines for automatic rotation in the list?

Or do I need to manually set the color of the line every time a new line is added to the list?

Based on the MSDN article, a manual method would look like this:

//alternate row color if (i % 2 == 0) { lvi.BackColor = Color.LightBlue; } else { lvi.BackColor = Color.Beige; } 

Answer 1

I am afraid that this is the only way in Winforms. XAML allows this to be used in styles.

Answer 2

Set the ListView OwnerDraw property to true, and then execute the DrawItem handler:

  private void listView_DrawItem(object sender, DrawListViewItemEventArgs e) { e.DrawDefault = true; if ((e.ItemIndex%2) == 1) { e.Item.BackColor = Color.FromArgb(230, 230, 255); e.Item.UseItemStyleForSubItems = true; } } 

This example is simple, you can improve it.

Answer 3

As far as I know, WPF allows you to set the style for any control using <Styles/> But in winforms I am afraid that this is the only way.

Answer 4

You can also use the owner’s drawing, rather than setting properties explicitly. Owner pattern is less vulnerable to reordering items.

Here's how to do it in Better ListView (a third-party component that offers both free and advanced versions) - it's just a matter of handling the DrawItemBackground event:

 private void ListViewOnDrawItemBackground(object sender, BetterListViewDrawItemBackgroundEventArgs eventArgs) { if ((eventArgs.Item.Index & 1) == 1) { eventArgs.Graphics.FillRectangle(Brushes.AliceBlue, eventArgs.ItemBounds.BoundsOuter); } } 

result:

Answer 6

  for (int i = 0; i <= listView.Items.Count - 1; i = (i + 2)) { listView.Items[i].BackColor = Color.Gainsboro; } 

Set the main background in the properties menu, then use this code to set an alternate color.
