If you are working on webapplication (I assume its .net), then you can use javascript function as below

XML

<script type="text/javascript">
       function blanktextbox() {
           var textbx = document.getElementById('<%=TextBox1.ClientID%>');
           if (textbx.value == '0.00')
               textbx.value = '';
       }

       function filltextbox() {
           var textbx = document.getElementById('<%=TextBox1.ClientID%>');
           if (textbx.value == '')
               textbx.value = '0.00';
       }
   </script>

And in HTML your textbox will be

ASP.NET

<asp:textbox id="TextBox1" runat="server" onfocus="blanktextbox();" onblur="filltextbox();" xmlns:asp="#unknown"></asp:textbox>

and you are done :)

Though your solution to the question literally is right, I think this really isn't what OP is looking for.
What's the use of a textbox which cannot be used to enter any value. Yes, your code will always make the value 0.00 on blur, no matter what I enter.

revisite my code again. It will only make 0.00 if the value in textbox is blank. And thats what the request was.
