VB.net Listview Populate
提问by Naffel
I'm trying to populate a Listview in VB.net with items from my access database.
我正在尝试使用访问数据库中的项目填充 VB.net 中的 Listview。
So far, i've managed to fill it with all the items I want, but I need to the items under the right columns. (User and Comment)
到目前为止，我已经设法用我想要的所有项目填充它，但我需要右列下的项目。（用户和评论）
Here's all the relevant code:
这是所有相关代码：
Dim count As Integer
Dim comments As New DataSet
comments = GetComments(classid)
With CommentsView
.View = View.Details
.Columns.Add("User")
.Columns.Add("Comment")
End With
count = CountRecords() - 1
For i As Integer = 0 To count
CommentsView.Items.Add(comments.Tables(0).Rows(i).Item(2))
CommentsView.Items.Add(comments.Tables(0).Rows(i).Item(3))
Next
So essentially I want Item(2) under Users and Item(3) under comments. Any ideas?
所以基本上我想要用户下的 Item(2) 和评论下的 Item(3) 。有任何想法吗？
Thanks.
谢谢。

You are adding Items which equate to rows in a LV, you need to add User and Comment as SubItems (which visually equates to columns).
您正在添加相当于 LV 中的行的项目，您需要将用户和评论添加为子项目（在视觉上相当于列）。
Dim LVI as ListViewItem
' no need for a count temp var
For i As Integer = 0 To CountRecords() - 1
LVI = New ListViewItem
' whatever you want to show in columns 0
LVI.Text = (What_Ever_Text_For_Col_0)
' add subitem text
' this is adding strings from a dataset, but could be any string
LVI.SubItems.Add(comments.Tables(0).Rows(i).Item(2)) ' maybe .ToString?
LVI.SubItems.Add(comments.Tables(0).Rows(i).Item(3))
' add completed LVI to the LV
CommentsView.Items.Add(LVI)
Next
