如何强制ListView忽略单击/不突出显示单击的项目？

Question

由于我没有根据用户可能选择的内容处理ListView中的项目（处理总是使用列表中的所有内容），我想禁止选择可能使用户认为他将处理限制为那个项目（我已经有多选=假，所以这不是问题）。

Answer 1

There is not any property to disable item selection in the ListView .

What you can do is to handle the event that notifies that an item has been selected by attaching an event handler to ItemSelectionChanged and then deselect the item:

yourListView.ItemSelectionChanged += yourListView_ItemSelectionChanged;

private void yourListView_ItemSelectionChanged(
    object sender,
    ListViewItemSelectionChangedEventArgs e)
{
   if (e.IsSelected)
      e.Item.Selected = false;
}

Answer 2

To add to Adriano Repettis soloution, I had something similar where I grayed out the items I wanted to block, his solution prevents the blue highlight but the Item still has focus which causes a problem when the item's backcolor is set to anything but white since some of the selected line becomes white. to handle this, I suggest adding the line:

e.Item.Focused = false;

the final code:

yourListView.ItemSelectionChanged += yourListView_ItemSelectionChanged;

private void yourListView_ItemSelectionChanged(
    object sender,
    ListViewItemSelectionChangedEventArgs e)
{
    if (e.Item.BackColor == Color.LightGray)
    {
        e.Item.Selected = false;
        e.Item.Focused = false;
    }
}
