        colPorsionDescription = New System.Windows.Forms.DataGridViewTextBoxColumn

        colPorsionToSelect = New System.Windows.Forms.DataGridViewComboBoxColumn
 

        colPorsionDescription.ReadOnly = True

        colPorsionDescription.CellTemplate.Style.Alignment = DataGridViewContentAlignment.MiddleRight

        colPorsionToSelect.CellTemplate.Style.Padding = New Padding(5, 11, 5, 11)
 

        colPorsionToSelect.Width = 120

        colPorsionToSelect.DropDownWidth = 80

        colPorsionToSelect.MaxDropDownItems = 3

        colPorsionToSelect.FlatStyle = FlatStyle.Flat
 

        lblSelectPorsionsCaption.Font = New System.Drawing.Font("Microsoft Sans Serif", 10.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))
 

        With grdPorsions

            .DefaultCellStyle.Font = New System.Drawing.Font("Microsoft Sans Serif", 10.0!, System.Drawing.FontStyle.Regular, System.Drawing.GraphicsUnit.Point, CType(0, Byte))

            .BorderStyle = BorderStyle.Fixed3D

            .BackgroundColor = Color.OldLace

            .SelectionMode = DataGridViewSelectionMode.CellSelect

            .DefaultCellStyle.BackColor = Color.White

            .DefaultCellStyle.SelectionBackColor = Color.White

            .DefaultCellStyle.SelectionForeColor = Color.Black

            .MultiSelect = False

            .EditMode = DataGridViewEditMode.EditOnEnter

            .RowHeadersVisible = False

            .ColumnHeadersVisible = False

            .Columns.AddRange(New System.Windows.Forms.DataGridViewColumn() {colPorsionDescription, colPorsionToSelect})

            .ScrollBars = ScrollBars.None
 

            .Columns(0).Width = 272

            .Columns(1).Width = 120

            .AllowUserToAddRows = False

            .AllowUserToResizeColumns = False

            .AllowUserToResizeRows = False

            For iRowCount = 0 To 4

                .Rows.Add()

                .Rows(iRowCount).MinimumHeight = 47

            Next iRowCount
 

            .Rows(0).Cells(0).Value = "Item 1 : "

            .Rows(1).Cells(0).Value = "Item 2 : "

            .Rows(2).Cells(0).Value = "Item 3 : "

            .Rows(3).Cells(0).Value = "Item 4 : "

            DropDownColumn = grdPorsions.Columns(1)

            For i = 0 To 200

                DropDownColumn.Items.Add(i & "")

                DropDownColumn.DisplayMember = i & ""
