I have some line code that is written in VB6 and now I use Datagridview in C# but I do not know how to coding for datagridview that is it handle event the same code in VB6.

this is event TextTipFetch of control Fpspread in VB6.

Private Sub SpreadAccident_TextTipFetch(ByVal Col As Long, ByVal Row As Long, MultiLine As Integer, TipWidth As Long, TipText As String, ShowTip As Boolean)    
    If Col = 1 And Row = 0 Then 
        TipText = "This is ID column"
        MultiLine = 1
        TipWidth = 8000
        ShowTip = True
    End If 
End Sub

Corresponding this event, which event should I use of datagridview and how to coding?

Addition on there are code in VB6 as below:

1. SpreadAccident.TypePictPicture=LoadPicture("")
2. SpreadAccident.TypePictPicture = PicA.Image;

(PicA is Picturebox in VB6)

So how is Coding in datagridview(C#) to handle 2 this line code in vb6?
