This property returns the value of the DataGridViewComboBoxCell.Items property of the System.Windows.Forms.DataGridViewComboBoxCell returned by the DataGridViewComboBoxColumn.CellTemplate property.
The DataGridViewComboBoxColumn.Items or DataGridView.DataSource properties are used to populate the selections of the combo boxes.
If strings are added to DataGridViewComboBoxColumn.Items, then the DataGridViewComboBoxColumn.ValueMember and DataGridViewComboBoxColumn.DisplayMember properties do not need to be set because each string added will be used for both value and display.
System.Windows.Forms.DataGridViewComboBoxColumn does not support the use of multiple items with identical display values.
If the DataGridViewComboBoxColumn.DataSource property is set, then DataGridViewComboBoxColumn.Items cannot be used.
