关于在列表视图中删除行时的行号的问题 [英] Question about row number when delete Row in listview

问题描述

现在我已经在数据库中添加了行号

但是删除行时出现问题

Now i''ve add row number in database already

but i''ve problem when i''ve delete row

private void listView1_MouseDoubleClick(object sender, MouseEventArgs e)
       {
           for (int i = 0; i <= listView1.SelectedItems.Count - 1; i++)
           {
               ListViewItem lvi = listView1.SelectedItems[i];
               listView1.Items.Remove(lvi);
           }
       }

示例我删除了第3行，我删除了5行

第一行编号为12345
当我删除它时会显示1245
我希望它成为1234

我找到了解决此问题的方法，但是它在VB中

推荐答案

我认为，您正在使用数据表来绑定列表视图.那么您可以从数据表中删除，而不是从列表视图中删除.再次删除将数据表绑定到列表视图后.

它将解决您的问题.

不要忘记标记它是否是您的解决方案.

永远与您在一起:-)

Hi,

as i think, you are using datatable to bind list view. then you can remove from datatable not from list view. after removing bind datatable to list view again.

It will solve your problem.

Don''t forget to mark if it is your solution.

With you for you always :-)

也许删除后的绑定应该可以.

Perhaps a bind after remove should do it.

               if (listView1.Items[i].Selected == false) //<< inverse Select
               {
                   countnum += 1;
                   data_new[0] = (countnum).ToString();
                   data_new[1] = listView1.Items[i].SubItems[1].Text;
                   data_new[2] = listView1.Items[i].SubItems[2].Text;

                   data_new[6] = listView1.Items[i].SubItems[6].Text;

                   dt1.Rows.Add(data_new); //datatabel ใหม่ที่ลบแล้ว
               }
           }

               {
                   subitems[i] = o[i].ToString();
               }
               ListViewItem item = new ListViewItem(subitems);
               listView1.Items.Add(item);
