C# ListView - control checkBox event
提问by user366312
Suppose I need to change the status of an item from active = true to active = false and vise versa and at the same time persist my change in the database table.
假设我需要将一个项目的状态从 active = true 更改为 active = false ，反之亦然，同时在数据库表中保留我的更改。
I tested ItemChecked event like the following:
我测试了 ItemChecked 事件，如下所示：
private void listView1_ItemChecked(object sender, ItemCheckedEventArgs e)
{
ListViewItem item = (ListViewItem)sender;
if (item != null)
{
Book b = (Book) item.Tag;
b.MakeActive(item.Checked);
}
}
I failed.
我失败了。

in this case object senderis ListViewand not ListViewItemyour code should be this
在这种情况下object sender是ListView而不是ListViewItem你的代码应该是这样的
private void listView1_ItemChecked(object sender, ItemCheckedEventArgs e)
{
ListViewItem item = e.Item as ListViewItem;
if (item != null)
{
Book b = (Book) item.Tag;
b.MakeActive(item.Checked);
}
}
