ASP:NET Confirm Password field

Question

Im creating a simple registration form in asp.net. Here's my problem: If my confirm passwordfield is empty it still submits the form. I'm using compareToValidate do I also need to use a requiredvalidator. I'm new to asp.net but shouldnt the comparevalidator generate an error if lets say password is 123 and the confirmpassword is empty.

        <fieldset>
       <legend>Enter your data</legend>
       <table>
        <tr>
       <td align="right">User Name :</td>
       <td>&nbsp;</td>
         <td align="left">
        <asp:TextBox ID="tbUsername" runat="server"></asp:TextBox>
    <asp:RequiredFieldValidator ID="rfvUserName" runat="server" 
        ControlToValidate="tbUsername" 
        CssClass="ValidationError"
        ErrorMessage="&laquo; (Required)"
        ToolTip="User Name is a REQUIRED field"
        ></asp:RequiredFieldValidator>
        </td>
</tr>`enter code here`
<tr >
<td align="right">Password&nbsp;:&nbsp;</td>
<td>&nbsp;</td>
<td align="left"> 
    <asp:TextBox ID="tbPassword" runat="server" TextMode="Password"></asp:TextBox>
    <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" 
     ErrorMessage="&laquo; (Required)" 
     ControlToValidate="tbPassword"
     CssClass="ValidationError"

    ToolTip="Password is a REQUIRED field"
    ></asp:RequiredFieldValidator>
</td>

</tr>
<tr >
<td align="right">Confirm Password&nbsp;:&nbsp;</td>
<td>&nbsp;</td>
<td align="left"> 
    <asp:TextBox ID="ConfirmPass" runat="server" TextMode="Password"></asp:TextBox>
     <asp:CompareValidator ID="CompareValidator1" runat="server" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ControlToCompare="tbPassword"
     ErrorMessage="No Match" 
     ToolTip="Password must be the same" />

</td>

</tr>

You must provide a required validator as well! Compare validator will only compare the value with the target control and alert the user.

<td align="left"> 
    <asp:TextBox ID="ConfirmPass" runat="server" TextMode="Password"></asp:TextBox>

    <asp:CompareValidator ID="CompareValidator1" runat="server" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ControlToCompare="tbPassword"
     ErrorMessage="No Match" 
     ToolTip="Password must be the same" />

    <asp:RequiredFieldValidator ID="RequiredFieldValidator2" runat="server" 
     ErrorMessage="&laquo; (Required)" 
     ControlToValidate="ConfirmPass"
     CssClass="ValidationError"
     ToolTip="Compare Password is a REQUIRED field">
    </asp:RequiredFieldValidator>
</td>

Hopes this help you!
