Datagridview Combobox Cell Max Dropdown无法正常工作

Question

不知何故，当我要求时，它仍然会显示超过10个值。这是否是正确的方式？

               Dim c3 As New DataGridViewComboBoxColumn()

c3.HeaderText = "Stripes"
c3.DataSource = BndSrc

c3.Name = "Stripes"

c3.DataPropertyName = "Stripes"
c3.DisplayMember = "Stripes"
c3.ValueMember = "Stripes"

c3.DisplayStyleForCurrentCellOnly = False
c3.DisplayStyle = DataGridViewComboBoxDisplayStyle.Nothing
c3.FlatStyle = FlatStyle.Standard
c3.SortMode = DataGridViewColumnSortMode.Automatic
c3.maxdrodownitems = 3 
Me.DataGrid.Columns.Add(c3)
