thank you

Hi,

You don't need to call ElementFromPoint - the event args give you the element. So you can skip that and go straight to calling GetContext on the element.

Thanks for pointing me to the right direction.  Since I have a treeview with details view, and rows 18 columns wide. I had to spend some time figuruing out over which cell mouse is over but I think I finally got it.   If you think there is a better solution, please let me know.

    Private Sub tvTicket_MouseEnterElement(ByVal sender As Object, ByVal e As Infragistics.Win.UIElementEventArgs) Handles tvTicket.MouseEnterElement
        Dim nodeAtPoint As UltraTreeNode = tvTicket.GetNodeFromPoint(e.Element.Rect.X, e.Element.Rect.Y)

        If nodeAtPoint IsNot Nothing Then
            Dim pt As New Point(e.Element.ControlElement.CurrentMousePosition.X, e.Element.ControlElement.CurrentMousePosition.Y)
            Dim child As Infragistics.Win.UIElement = e.Element.ElementFromPoint(pt)
            If child IsNot Nothing Then
                Dim cell As UltraTreeNodeCell = TryCast(child.GetContext(GetType(UltraTreeNodeCell)), UltraTreeNodeCell)
                If cell IsNot Nothing Then
                    UltraToolTipManager2.SetUltraToolTip(tvTicket, New Infragistics.Win.UltraWinToolTip.UltraToolTipInfo(cell.Text, Infragistics.Win.ToolTipImage.Default, "Test", Infragistics.Win.DefaultableBoolean.True))
                    UltraToolTipManager2.ShowToolTip(tvTicket)
                ElseIf UltraToolTipManager2.IsToolTipVisible Then
                    UltraToolTipManager2.HideToolTip()
                End If
            ElseIf UltraToolTipManager2.IsToolTipVisible Then
                UltraToolTipManager2.HideToolTip()
            End If
        ElseIf UltraToolTipManager2.IsToolTipVisible Then
            UltraToolTipManager2.HideToolTip()
        End If
    End Sub

Hi Nick,

Placing the UltraToolTipManager on the form has no effect on the tree. The properties of the UltraToolTipManager only affect tooltips that are displayed by the UltraToolTipManager. The tree has it's own built-in tooltips and there is no connection between the two.

If you want to control the delay, I think what you need to do is turn off the tree's built-in tooltips (using the TipStyleCell property on the column) and then you could add your own tooltips using the UltraToolTipManager.

Hello Nick,

I tried this and it always works fine for me so I attached my sample to this post for you. Please review it and feel free to let me know if I misunderstood you or if you have any other questions.
