I have a DataGridView that gets me values from a SQL Server table, I select a product and when I give click to the next cell, I get its price, this is generated with the event CellEndEdit , but I require change the price value manually.

How do I deactivate that event so I can enter the new price, can it?

What do I want to do with a CheckBoxColumn when I am selected to let me edit and when not, can not be per row or how could it work?

Suppose the following:

In your DataGridView the first column is type CheckBoxColumn whereby it will be the index = 0; and column 3 is the Precio in the event CellValueChanged of your DataGridView can do something like this:

private void DataGridView1_CellValueChanged(object sender, DataGridViewCellEventArgs e)
{
    if (e.ColumnIndex == 1)
    {
        object value = DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
        if (value == true) 
        {
            DataGridView1.Rows[e.RowIndex].Cells[3].ReadOnly = true;
        } else 
        {
            DataGridView1.Rows[e.RowIndex].Cells[3].ReadOnly = false;
        }
    }
}

If this gives you an exception:

object value = DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value;
if (value == true)

You can also do it like this:

if (Convert.ToBoolean(DataGridView1.Rows[e.RowIndex].Cells[e.ColumnIndex].Value) == true)

With this no you are disabling the event CellEndEdit as such, what you are doing is the cell Precio that you want to modify whether or not it is editable.
