VB.NET ListView在第一行插入项目。 [英] VB.NET ListView Insert item in first row.

问题描述

我正在创建一个从ftp服务器下载文件的程序。

将所有下载的文件和下载文件放在ListView中。

我想优先考虑下载文件所以我想在第一个索引中添加项目。



我尝试使用这个示例代码但它不起作用。

I'm creating a program that downloads file from ftp server.
Putting all downloaded files and downloading files in a ListView.
I want to prioritize the downloading file so I want to add the item in first index.

I try using this sample code but it doesn't work.

'FIRST DOWNLOAD
With lstDownload.Items.Add("Sample", 0)
        .SubItems.Add(2)
        .SubItems.Add(3)
        .SubItems.Add(4)
        .SubItems.Add(5)
        .SubItems.Add(6)
        .SubItems.Add(listDownload.Count - 1)
    End With
'SECOND DOWNLOAD
    With lstDownload.Items.Add("Sample1", 0)
        .SubItems.Add(2)
        .SubItems.Add(3)
        .SubItems.Add(4)
        .SubItems.Add(5)
        .SubItems.Add(6)
        .SubItems.Add(listDownload.Count - 1)
    End With

在该示例中，我想首先在ListView中显示Sample1。



任何人都可以向thi发布代码/建议s。



感谢先进...完全赞赏

In that example I want to display the "Sample1" first in the ListView.

Can anyone post a code/suggestion to this.

Thanks in advanced... totally appreciated

推荐答案

你好，



解决方案是使用Insert而不是Add。

Hello,

A solution is to use Insert instead of Add.

'FIRST DOWNLOAD
With lstDownload.Items.Add("Sample", 0)
    .SubItems.Add(2)
    .SubItems.Add(3)
    .SubItems.Add(4)
    .SubItems.Add(5)
    .SubItems.Add(6)
    .SubItems.Add(listDownload.Count - 1)
End With
'SECOND DOWNLOAD
With lstDownload.Items.Insert(0, "Sample1", 0)
    .SubItems.Add(2)
    .SubItems.Add(3)
    .SubItems.Add(4)
    .SubItems.Add(5)
    .SubItems.Add(6)
    .SubItems.Add(listDownload.Count - 1)
End With

你可以试试像

you could try something like

Dim listDownloads as New List(of ListViewItem)

Dim lvItem as ListViewItem

lvitem = New ListViewItem()
lvitem.text = "Sample"
lvitem.subitems.add(2)
lvitem.subitems.add(3)
lvitem.subitems.add(4)
lvitem.subitems.add(5)
lvitem.subitems.add(6)
'Set your colour and stuff here
'lvitem.backcolor

listDownloads.add( lvitem ) 'Add the item to an array

'Now add the items to the listview
Dim iCount as integer

For iCount = yourlistview.items.count -1 to 0 step -1
  yourlistview.items.add( lvitem )
Next

private void aboutToolStripMenuItem_Click(object sender, EventArgs e)
{
        ListViewItem lvi = new ListViewItem("Add "+DateTime.Now);
        ListViewItem.ListViewSubItem lvsi = new ListViewItem.ListViewSubItem();
        lvsi.Text = DateTime.Now.ToString();
        lvi.SubItems.Add(lvsi);
        _list.Insert(0, lvi);
        listView1.Invalidate();
}
