C# object sender - getting the Method from which it was called
<p>I've got these Methods:</p>

<pre><code>    private void button_Click(object sender, EventArgs e)
    {
          //Changes the Text in the RichBox, EXAMPLE:
          richtTextBox.Text = "Now Changed and calling Method richTextBox_TextChanged";
    }
</code></pre>

<p>And,</p>

<pre><code> private void richTextBox_TextChanged(object sender, EventArgs e)
 {
         //Wants something like that
         if(called from button_click)
         {
           //DO SOMETHING
         }
         else
         {
           //DO SOMETHING
         }
 }
</code></pre>

<p>How can I handle this, to know if it was called from the Button_click?
Do I have to use the object sender to get informations? But how?</p>

<p>Hope u guys can help me</p>
