hiding a rows in DataGridViewComboBoxColumn

[Nik Edmiidz]

After a value from the combobox has been selected in a previous row of the
DataGridView, I would like to hide that value from being selectable in the
combobox in a new row of the DataGridView.

Here is a visual sample of what I'm trying to do:

I've found code to hide rows from DataGridView, but not from the
DataGridViewComboBoxColumn.

Any help much appreciated.

thanks,

The only solution i've found until now is the following:

- Add all available values to the ComboBoxColumn
- Handle the EditingControlShow event of the DataGridView: check if
e.Contol is a ComboBox, and remove the values that shouldn't be
available at that time from the Items collection on that ComboBox.
