Regular Expression for (dd-mm-yyyy) not working properly
<p>I have a RegularExpressionValidator in my ASP.Net page</p>

<p>I am using it for checking the valid date including leap year against the TextBox Control.</p>

<p>The code is:</p>

<pre><code>&lt;asp:RegularExpressionValidator ID="RegularExpressionValidator1" runat="server"   
ErrorMessage="Enter Valid Date" Display="Dynamic" Font-Bold="true" ForeColor="Red" 
ValidationExpression=
"^(((0[1-9]|[12]\d|3[01])(-|\/)(0[13578]|1[02])(-|\/)((19|[2-9]\d)\d{2}))|((0

[1-9]|[12]\d|30)(-|\/)(0[13456789]|1[012])(-|\/)((19|[2-9]\d)\d{2}))|((0[1-9]|1      
\d|2[0-8])(-|\/)02(-|\/)

((19|[2-9]\d)\d{2}))|(29(-|\/)02(-|\/)((1[6-9]|[2-9]\d)(0[48]|[2468][048]|[13579]
[26])|   ((16|[2468]

[048]|[3579][26])00))))$" ControlToValidate="txtbdate"&gt;  
&lt;/asp:RegularExpressionValidator&gt;
</code></pre>

<p>All dates are checked fine but the date : 09-09-2000 cannot be checked..</p>

<p>Please help..</p>

<p>Thanks in advance.</p>
