如果内容字符串宽度大于 ListBox 宽度，Winforms DotNet ListBox 项目以自动换行?

问题描述

嗯，嗯，这意味着有些行的大小应该是两行.我的老板认为这是更简单的解决方案，而不是限制显示的文本以适合宽度并且不喜欢水平滚动条>_<

Ehm, umm, this means some lines should be two-lined in size. My boss think this is more simple solution, than limit displayed text to fit width and don't like horizontal scroll bar >_<

推荐答案

lst.DrawMode = System.Windows.Forms.DrawMode.OwnerDrawVariable;
lst.MeasureItem += lst_MeasureItem;
lst.DrawItem += lst_DrawItem;

private void lst_MeasureItem(object sender, MeasureItemEventArgs e)
{
    e.ItemHeight = (int)e.Graphics.MeasureString(lst.Items[e.Index].ToString(), lst.Font, lst.Width).Height;
}

private void lst_DrawItem(object sender, DrawItemEventArgs e)
{
    e.DrawBackground();
    e.DrawFocusRectangle();
    e.Graphics.DrawString(lst.Items[e.Index].ToString(), e.Font, new SolidBrush(e.ForeColor), e.Bounds);
}
