And use InitialValue property of your validator control to specify the default value should be consider as empty

<asp:TextBox ID="TextBox1" runat="server" Text="Default Text"></asp:TextBox>
         <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server"
             ErrorMessage="Enter your text" InitialValue="Default Text"
             ControlToValidate="TextBox1" ValidationGroup="sub"></asp:RequiredFieldValidator>
         <br />
         <br />
         <asp:TextBox ID="TextBox2" runat="server" Text="Default Text"></asp:TextBox>
         <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" ErrorMessage="Enter your text" InitialValue="Default Text" ControlToValidate="TextBox2"></asp:RequiredFieldValidator>
         <br />
         <br />
         <asp:Button ID="Button1" runat="server" Text="Submit" ValidationGroup="sub" />

Two things:

http://msdn.microsoft.com/en-us/library/system.windows.forms.control.lostfocus%28v=vs.71%29.aspx

2> Use of Javascript Validation on Client Side:
