How can I make this even always work whether I check a radio button first or if I check combobox item first? Currently it only works if radio button is checked first. Thank you.

```
private void comboBox1_SelectedIndexChanged(object sender, EventArgs e)
{
    if ( comboBox1.Text == "Test1" && radioButton1.Checked)
    {
        StreamReader sr = new StreamReader(@"my path");
        string str = sr.ReadToEnd();
        textBox1.Text = str;
    }
}

```
