        e.Handled = true;
    }
}

VB.NET

Private gridView1.CustomDrawCell += AddressOf GridView1_CustomDrawCell

Private Sub GridView1_CustomDrawCell(ByVal sender As Object, ByVal e As RowCellCustomDrawEventArgs)
    Dim view As GridView = TryCast(sender, GridView)
    If column.ColumnType Is GetType(Date) Then
        e.Cache.FillRectangle(Color.Salmon, e.Bounds)
        e.Appearance.DrawString(e.Cache, e.DisplayText, e.Bounds)
        e.Handled = True
    End If
End Sub

Note

Columns return valid ColumnType property values only after a Grid is completely initialized. Call the GridControl.ForceInitialize() method to ensure you do not read the ColumnType property too early.
