How to set borderstyle of a datagridview column at runtime (.Net Framework 4.0)?
I have a readonly datagridview that is bound to a datasource. It has two columns. Now I want the first column to have no cell borderstyle; and the second one to have 'All' (i.e. all sides of the cell shall have a border) as cell borderstyle. Before binding the datagridview to the datasource, I'm writing something like mentioned below but it's taking no effect. Assume the column in question is named DisplayName.
Code:
With newStyle
.Top = DataGridViewAdvancedCellBorderStyle.Single
.Left = DataGridViewAdvancedCellBorderStyle.Single
.Bottom = DataGridViewAdvancedCellBorderStyle.Single
.Right = DataGridViewAdvancedCellBorderStyle.Single
End With
DisplayName.CellTemplate.AdjustCellBorderStyle(newStyle, newStyle, True, True, True, True)
Please rectify or suggest a better way. Regards.

Code:
Private Sub dgvLegends_CellPainting(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellPaintingEventArgs) Handles dgvLegends.CellPainting
'Draw custom cell borders.
'If current column is DisplayName...
If dgvLegends.Columns("DisplayName").Index = e.ColumnIndex AndAlso e.RowIndex >= 0 Then
Dim Brush As New SolidBrush(dgvLegends.ColumnHeadersDefaultCellStyle.BackColor)
e.Graphics.FillRectangle(Brush, e.CellBounds)
Brush.Dispose()
e.Paint(e.CellBounds, DataGridViewPaintParts.All And Not DataGridViewPaintParts.ContentBackground)
ControlPaint.DrawBorder(e.Graphics, e.CellBounds, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid, dgvLegends.GridColor, 1, ButtonBorderStyle.Solid)
e.Handled = True
End If
End Sub
