How can I prevent users from entering data in the DataGridViewComboBoxCells?

Question

I have a project that uses several DataGridView controls. Most cells have a DataGridViewTextBoxCell conviction. I declare my controls like this:

Dim MyCell as DataGridViewCell

Later I will clarify whether they are DataGridViewTextBoxControls or DataGridViewComboBoxCells as follows:

MyCell = New DataGridViewTextBoxCell   ...or...
MyCell = New DataGridViewComboBoxCell

None of the places in my code require users to enter their own values ​​in Combo Boxes. That is, they are either hardcoded or the values ​​are collected from other data in the application.

Currently, users can highlight the list control as shown above and start typing whatever they like. For example, I have one combo box that offers the user a choice of integers from 1 to 9. I can select the combo box and enter "Hello, World!". if i wanted to.

What do you need to disable this ability? I am sure that there is property, but I still have to find it. I searched the Internet and found only the ability to add user-entered values ​​to the list and the flow of training instructions for data binding.

Thank you in advance! WITH
