You get the values for the columns fromthe subitems, e.g
Dim LView As New ListView
LVItem.SubItems(0).Text = "First Column"
LVItem.SubItems(1).Text = "Second Column"

Open in new window

Or you can retrieve all the items in a listview and iterate over them
Dim LView As New ListView
For Each x As ListViewItem In LView.Items
    Dim First = x.SubItems(0)
    Dim Second = x.SubItems(1)
Next

Use the same to set values, e.g
Dim LView As New ListView
For Each x As ListViewItem In LView.Items
    x.SubItems(0).Text = "Set First Column"
    x.SubItems(1).Text = "Set Second Column"
Next

Hi Nepaluz,

I am trying to add two columns, and has about 5 rows. The data is fed from the database using an OledbDataReader.

The first column will have ID number and the second column will have names, could you please show me the code to achieve that grammatically.

Thanks in advance.

I have tried to mimic your returned datatable with a manual one, here goes....
Dim LVTable As DataTable = New DataTable("LVTbl")
LVTable.Columns.AddRange({New DataColumn With {.ColumnName = "FirstCol"}, New DataColumn With {.ColumnName = "SecondCol"}})
LVTable.Rows.Add({"First", "First Value"})
LVTable.Rows.Add({"Second", "Second Value"})
LVTable.Rows.Add({"Third", "Third Value"})
Dim LView As New ListView
'hereswhere youadd theitems
For Each x As DataRow In LVTable.Rows
    Dim LVItem As New ListViewItem
    LVItem.SubItems(0).Text = x.Item(0)
    LVItem.SubItems(1).Text = x.Item(1)
    LView.Items.Add(LVItem)
Next
