how to wrap a merged cells of datagridview column in vs2010 (vb.net)

Can you be more descriptive in stating what you need? What you want to accomplish?

I have a column in datagrid with merged cells. I need to wrap the text in merged cells.  I am able to do the text wrapping unmerged cells

Can you post the code how you are merging and un-merging cells in your code

Column to be merged in datagridview -  2
       
dgv1.Columns(2).Width = 200
 dgv1.Columns(2).DefaultCellStyle.Alignment = DataGridViewContentAlignment.MiddleCenter   in form load event

  If e.ColumnIndex = 2 AndAlso e.RowIndex <> -1 Then

            Using gridBrush As Brush = New SolidBrush(Me.dgv1.GridColor), backColorBrush As Brush = New SolidBrush(e.CellStyle.BackColor)

                Using gridLinePen As Pen = New Pen(gridBrush)
                    ' Clear cell  
                    e.Graphics.FillRectangle(backColorBrush, e.CellBounds)

                    ' Draw line (bottom border and right border of current cell)  
                    'If next row cell has different content, only draw bottom border line of current cell  
                    If e.RowIndex < dgv1.Rows.Count - 1 AndAlso dgv1.Rows(e.RowIndex + 1).Cells(e.ColumnIndex).Value.ToString() <> e.Value.ToString() Then
                        e.Graphics.DrawLine(gridLinePen, e.CellBounds.Left, e.CellBounds.Bottom - 1, e.CellBounds.Right - 1, e.CellBounds.Bottom - 1)
                    End If

                    ' Draw right border line of current cell  
                    e.Graphics.DrawLine(gridLinePen, e.CellBounds.Right - 1, e.CellBounds.Top, e.CellBounds.Right - 1, e.CellBounds.Bottom)

                    ' draw/fill content in current cell, and fill only one cell of multiple same cells  
                    If Not e.Value Is Nothing Then
                        If e.RowIndex > 0 AndAlso dgv1.Rows(e.RowIndex - 1).Cells(e.ColumnIndex).Value.ToString() = e.Value.ToString() Then
                        Else
                            e.Graphics.DrawString(CType(e.Value.ToString, String), e.CellStyle.Font, Brushes.Black, e.CellBounds.X + 2, e.CellBounds.Y + 5, StringFormat.GenericDefault)
                        End If
                    End If

                    e.Handled = True
                End Using
            End Using
        End If

dgv1.Columns(2).DefaultCellStyle.WrapMode = DataGridViewTriState.True
