Hi,

 Here is a way to get the Row Index, Column Index, and the Text of the row and column of the clicked item in a ListView. The FullRowSelect must be set True for this to work. You can use the ListView_DoubleClick event or the ListView_Click event like this

Public Class Form1

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        'This property can be set in the designer window instead of here
        ListView1.FullRowSelect = True
    End Sub

    Private Sub ListView1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles ListView1.Click
        Dim sp As New Point(MousePosition.X - Me.PointToScreen(ListView1.Location).X, MousePosition.Y - Me.PointToScreen(ListView1.Location).Y)
        Dim ht As ListViewHitTestInfo = ListView1.HitTest(sp)
        Select Case ht.Location
            Case ListViewHitTestLocations.Label
                Dim cwb, cwe, cnt As Integer
                For Each col As ColumnHeader In ListView1.Columns
                    cwe += col.Width
                    If sp.X > cwb And sp.X < cwe Then
                        Exit For
                    End If
                    cnt += 1
                    cwb = cwe
                Next
                TextBox1.Text = "Selected Text=" & ht.SubItem.Text & "   Row Index=" & ht.Item.Index.ToString & "   Column Index=" & cnt.ToString
            Case Else
                TextBox1.Text = "Selected Text=" & ht.Item.Text & "   Row Index=" & ht.Item.Index.ToString & "   Column Index=0"
        End Select
    End Sub
End Class

Worked perfectly! Just what I was looking for!

Let me ask you another question, regarding listview events, how do you get the value of the scrollbar when using listview procedures?

Thank you in advance.

Hey,

 I don`t think there is a scrollBar value you can get but, you can get the (TopItem.Index) which tells you which row index is showing at the top of the Listview.

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim indx As Integer = ListView1.TopItem.Index
        MessageBox.Show(indx.ToString)
    End Sub

Please don`t forget to mark my above post as the answer so others can find it when looking for an answer for the same question.  :)
