Error when trying to run method
<p>I have made this program and I dont know how to make it run. I usualy run my methods inside the 2 big methods that I have <code>button1_Click</code> (<code>private void button1_Click(object sender, EventArgs e)</code>)  and <code>button2_Click</code>  (<code>private void button2_Click(object sender, EventArgs e)</code>).</p>

<p><strong>I write <code>this.Lista();</code> in the button1_Click method and it gives me the error: <em>No overload for method 'Lista' takes 0 arguments.</em></strong></p>

<pre><code>public void Lista(object sender, EventArgs e)
{
    string[] col2 = new string[dataGridView1.Rows.Count];

    for (int i = 0; i &lt; dataGridView1.Rows.Count; i++)

            if (col2[i] == "Browse From File...")
            {
                DialogResult result2 = openFileDialog2.ShowDialog();
                if (result2 == DialogResult.OK)
                {
                   // filename = openFileDialog1.FileName;
                }
}
}
</code></pre>
