title: Button Click Event Won't Return Value to Textbox
body: <p>I have two buttons on my web form.  When clicking on the first button, the event does not fire.  Here's what I've placed in the click event handler:</p>
  
  <pre><code>protected void btnRFC_Click(object sender, EventArgs e)
  {
      string strDOB = drpDay.SelectedValue + "/" + drpmonth.SelectedValue + "/" + txtyear.Text;
      string strRFC = CURPRFC.CalcularRFC(txtfirstname.Text, txtmiddlename.Text, txtlastname.Text, strDOB );
      txtrfc.Text = strRFC;
  }
  </code></pre>
  
  <p>strDOB is needed to get the date fields into one string used in CalcularRFC for the date value.  The event handler for the second button is too large to post, but currently works as expected.  But, the above handler does not return a value to txtrfc.  Can someone point me in the right direction?</p>
  
  <p>Thanks,
  Sid</p>
