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?
推荐答案
在的ListView
控件不支持在分项图像本身。最容易做的事情是切换到的DataGridView
和使用 DataGridViewImageColumn
。如果这是不可能的,那么你就需要使用自定义绘制支持,在的ListView
控制自己绘制的图标。要做到这组 ListView.OwnerDraw = TRUE
并办理 ListView.DrawSubItem
和的ListView。 DrawColumnHeader
事件。
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;
}
