Delphi 7-如何使用标题从列表视图中删除项目

问题描述

限时删除！！

我正在尝试根据标题删除列表视图项，但是我找不到解决方案，删除索引的唯一方法是使用索引：

i'm trying to delete a listview item based into caption, but I can not find a solution for this, the only way I can delete an item is using the index:

listview1.Items.Delete (0);

有人可以帮助我通过标题删除项目吗？

Can anyone help me to delete an item through the caption?

推荐答案

您可以使用类似的方法，该方法试图找到标题为 ListItem >项目2 ，并在找到它后将其删除：

You can use something like this, which attempts to locate a ListItem with the caption Item 2, and deletes it if it find it:

procedure TForm1.Button1Click(Sender: TObject);
var
  LI: TListItem;
begin
  LI := ListView1.FindCaption(0, 'Item 2', False, True, False);
  if Assigned(LI) then
  begin
    ListView1.Selected := LI;
    ListView1.DeleteSelected;
  end;
end;

另一种不需要您首先选择项目的方法是删除找到的项目索引：

An alternative which does not require you to select the item first would be to delete the found item by its Index:

procedure TForm1.Button2Click(Sender: TObject);
var
  LI: TListItem;
begin
  LI := ListView1.FindCaption(0, 'Item 2', False, True, False);
  if Assigned(LI) then
    ListView1.Items.Delete(LI.Index);
end;
