在.net 2010中循环计数列表视图中的数据 [英] Looping the data in listview with counted number in .net 2010

问题描述

大家好，

基于该主题，我已经访问了一些与我搜索将文本框中的数据添加到列表视图"有关的站点，并且打赌该步骤是可以接受的.但是现在，我想根据您在文本框中插入的数据量在listview中查看一个数字.我知道代码就像FOR xx到xxx ....下一步，但是详细编码，我无法编码.这是我访问的网站的代码示例.如果有人可以教，那是我的荣幸.

假设列表视图中有2个文本框但3列

第一栏:编号
第2栏:txt1
第三栏:txt2

原始代码示例:-

Hi all,

Based from the subject, I already visit some sites that relate to what I searching "Adding data from textbox to listview" and I bet that the step was acceptable. But right now, I want to view a number in listview based on how many data you inserted in textbox. I know the code was like FOR xx to xxx.... NEXT but the details coding, I failed to code. Here are the sample of code from site i visit. If someone can teach, it''s my pleasure.

Assume there are 2 textbox but 3 column in list view

Column 1st: Numbering
Column 2nd: txt1
Column 3rd: txt2

Sample of Original Code:-

dim li as new ListViewItem
li = ListView1.items.add(Textbox1.Text)
li.subitems.add(Textbox2.Text)

推荐答案

每次添加新项时，请使用:

Each time whe you add new item, use:

Dim lvi As System.Windows.Forms.ListViewItem = Nothing
Dim lvs1 As System.Windows.Forms.ListViewItem.ListViewSubItem = Nothing
Dim lvs2 As System.Windows.Forms.ListViewItem.ListViewSubItem = Nothing

Try
    lvi = New System.Windows.Forms.ListViewItem(ListView1.Items.Count + 1)
    lvs1 = New System.Windows.Forms.ListViewItem.ListViewSubItem(lvi, TextBox1.Text)
    lvi.SubItems.Add(lvs1)
    lvs2 = New System.Windows.Forms.ListViewItem.ListViewSubItem(lvi, TextBox2.Text)
    lvi.SubItems.Add(lvs2)
    ListView1.Items.Add(lvi)
    ListView1.Refresh()

Catch ex As Exception
    MsgBox(ex.Message, MsgBoxStyle.Exclamation, "Error...")

Finally
    lvi = Nothing
    lvs1 = Nothing
    lvs2 = Nothing
End Try

好，您需要在ListView中添加列以反映子项并设置ListView.View = Details的属性.这是一个可以逐步帮助您的链接...
