求教listview删除选定项问题

Question

for (int i = listView1.SelectedItems.Count - 1; i >= 0; i--)
{
     ListViewItem item =listView1.SelectedItems[i];
     listView1.Items.Remove(item);
}
listView1.Refresh();

Answer 1

报错啊，myListBox4.SelectedItems[i];为Object类型，缺少强制转换

Answer 2

for(int i=LVCompany.Items.Count - 1; i >= 0;i--)
{
if (this.LVCompany.Items[i].Checked == false)      
continue;
this.LVCompany.Items[i].Remove();
}
这个是根据是否选中为条件来进行删除的

Answer 3

this.listView1.BeginUpdate();
            if (this.listView1.Items > 0)
            {
                foreach (ListViewItem item in this.listView1.SelectedItems)
                {
                    this.listView1.Items.Remove(item);
                }
            }
            this.listView1.EndUpdate();
或直接            this.listView1.SelectedItems.Clear();

Answer 4

if (this.myListBox.SelectedItems != null && this.myListBox.SelectedItems.Count != 0)
            {
                this.myListBox.Items.Remove(this.myListBox.SelectedItems[0]);
            }

Answer 5

for (int i = this.myListBox.Items.Count - 1; i >= 0; i--)
            {
                if (this.myListBox.GetSelected(i))
                {
                    this.myListBox.Items.RemoveAt(i);
                }
            }
安心用吧，关键点在于倒序

Answer 6

是不是这个异常：
System.InvalidOperationException
Operation is not valid while ItemsSource is in use. Access and modify elements with ItemsControl.ItemsSource instead.
？WPF，System.Windows.Controls(not Forms).ListBox/ListView？是的话，就往下看（这里我用ListView, ListBox应该也差不多）。假定ListView里每一行对应一个MyItem，MyCollection　定义如下：
public class MyCollection: ObservableCollection<MyItem>如果想remove，像这样（myListView 是一个ListView对象）：ICollectionView view = (ICollectionView)CollectionViewSource.GetDefaultView(myListView.ItemsSource);
MyCollection items = (MyCollection)view.SourceCollection;
items.RemoveAt(...); // 或者Remove() ...

这两个帖子好象重复了:http://topic.csdn.net/u/20070823/15/7f701696-5191-4260-8505-fc6dff2f53b5.html?seed=1311380912

Answer 8

            if (listView1.Items.Count == 0)
            {
                MessageBox.Show("未发现!", "提示");
                return;
            }
            else
            {
                if (listView1.SelectedItems.Count == 0)
                {
                    MessageBox.Show("Please select!", "Attention");
                    return;
                }
            }
            if (listView1.SelectedItems.Count != 0)
            {
                foreach (ListViewItem lv in listView1.SelectedItems)
                {                    this.listView1.Items.Remove(lv);
                }
            }
