Good day everyone please i have a datagridview where i store name,date and time, and i have a button that i don't want it to be visible if the row in the datagridview is greater than 1
but the button does not work properly

What I have tried:

if (exam.dataGridView1.Rows.OfType<DataGridViewRow>().Take(1).Count() > 1)
            {
                inexaminfo.Enabled = false;

if (exam.dataGridView1.Rows.Count >1)
            {
                inexaminfo.Enabled = false;
              
            }

So when the DataGridView displays the rows, only row 1 will have a button?
