I've got a multiline asp.textbox input control.

I don't know if my issue is with ASP.NET, the Multiline control, or something else, but the onblur and onfocus are not working.

```
<script type="text/javascript">
  var defaultMsg = 'Write your message here or or call my voice at (xxx) xxx-xxxx.';
  var controlMsg = doc.createElement("input");
  controlMsg.id = "txtMessage";
  controlMsg.type = "text";
  controlMsg.value = defaultMsg;
  controlMsg.onfocus=function jpFocus() { if (this.value == defaultMsg) this.value = ''; }
  controlMsg.onblur=function jpBlur() { if (this.value == '') this.value = defaultMsg; }
</script>

```

And later....

```
<asp:TextBox ID="txtMessage" Columns="30" Rows="6" runat="Server" TextMode="MultiLine" />

```

Does anyone see a reason why this should not be working?
