ListView中没有项目的行缩进 [英] No row indentation for items in ListView

问题描述

我目前正在开发某些软件，客户对特定的UI更改感到僵硬，这给我带来了一些麻烦:

I'm currently working on some software and the customer is dead-set on a specific UI change that has been giving me some trouble:

我希望ListView中的项目没有缩进.为了说明，我更改了ListView和项目的背景色.

I would like items in a ListView to not have any indentation. To illustrate I changed the backcolor of the ListView and the items.

现在，每个项目左侧的小块也应该是白色的.有什么想法吗?

Now, the little piece to the left of each item should also be white. Any ideas?

推荐答案

您可以设置

You can set the OwnerDraw property of ListView to true and using DrawItem, DrawColumnHeader and DrawSubItem draw the list view yourself.

例如:

private void listView1_DrawItem(object sender, DrawListViewItemEventArgs e)
{
    e.Graphics.DrawString(e.Item.Text, e.Item.Font, Brushes.Black, 
         new Rectangle(e.Bounds.Left-2, e.Bounds.Top, e.Bounds.Width, e.Bounds.Height));
}

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

private void listView1_DrawSubItem(object sender, DrawListViewSubItemEventArgs e)
{
    if(e.ColumnIndex>0)
        e.DrawDefault = true;
}

注意:

• 上面的呈现只是一个示例，它向您展示了如何在所需位置绘制项目文本，例如使用的ListView控件的rel ="nofollow"> OwnerDraw 属性.

• The above rendering is just an example and shows you how you can draw item text in desired location for example using using Graphics.DrawString.
• Also it shows you how to set e.DrawDefault = true; to perform default rendering.
• The first subitem of each ListViewItem object represents the parent item itself
• To avoid issues with graphics flickering when owner drawing, override the ListView control and set the DoubleBuffered property to true.
• To learn more, read documents of OwnerDraw property of ListView control.
