datasource as readonly - C#

Question

I have a DataGridView with properties DataSource = datatable() and readonly = false. readonly must be false since there are other columns that can be editable. How do I make all the columns in DataSource read only (not editable)?

The code is as follows:

type = new DataGridViewComboBoxColumn();
        table= new DataGridView
                         {
                             DataSource = datatable(), // this returns a DataTable object
                             AllowUserToAddRows = false,
                             AllowUserToDeleteRows = false,
                             RowHeadersVisible = false,
                             MultiSelect = false,
                             Name = "AgentTable",
                             AutoSize = true,
                             ReadOnly = false,
                         };
        table.Columns.Add(CreateStartButton());        
        type.Items.Add(" some table");
        type.ReadOnly = false;
        table.Columns.Add(type);

EDIT: the datagridview will contain 4 columns.

First column, each cell is a button (readonly doesnt matter)
second column, each cell is a drop down box (readonly is false)
third and fourth columns are created as DataTable object so (readonly must be true)

so my question is how to make the third and forth column read-only?

You mean: the columns in the data table should be readonly and the added columns editable? — Gert Arnold

It should be easy to iterate the columns after you create them all. I'd use something like this, but I'm calling it pseudocode because I don't know if DataColumn is the correct data type:

foreach(DataColumn col in table.Columns) {
    col.ReadOnly = true;
}
