Answer 1

I thought I'd mention that there is a ShowItemToolTips boolean attribute on ListView, if you want to use that instead of a ListBox. Set that attribute to true and then assign the ToolTipText values on the ListView items.

If you want to do it in a listbox you will need to do it manually. Add a tooltip to the form and update the tooltip based on the mouses postion. An easier way to do this might be to use a DataGridView control like this:

    DataGridView1.RowHeadersVisible = False
    DataGridView1.ColumnHeadersVisible = False
    DataGridView1.Columns(0).AutoSizeMode = DataGridViewAutoSizeColumnMode.AllCellsExceptHeader
    Dim mydata As String() = {"Item 1", "Item 2", "Item 3", "Item 4", "Item 5", "Item 6"}
    For Each dataitem As String In mydata
        DataGridView1.Rows.Add(dataitem)
    Next
    For Each row As DataGridViewRow In DataGridView1.Rows
        row.Cells(0).ToolTipText = "ToolTip for " & row.Cells(0).Value
    Next row

I able to resolve thorough below ways:

'tooltip
Dim toolTip As ToolTip = New ToolTip()
    Private Sub lstReports_MouseMove(sender As Object, e As MouseEventArgs) Handles lstReports.MouseMove
    Dim index As Integer = lstReports.IndexFromPoint(e.Location)
    If (index <> -1 AndAlso index < lstReports.Items.Count) Then
        If (toolTip.GetToolTip(lstReports) <> lstReports.Items(index).ToString()) Then
            toolTip.SetToolTip(lstReports, lstReports.Items(index).ToString())
        End If
    End If
End Sub

Sadly, there is no implemented way to show ToolTips on each individual ListBox Item.

You can create your own ListBox control that allows you to do that, like this one: http://www.codeproject.com/Articles/457444/Listbox-Control-with-Tooltip-for-Each-Item
