I have used a required field validator followed by a regular expression validator but the required field validator is not working.....

<asp:TextBox ID="txtSummary" runat="server" TextMode="MultiLine" Width="700px"

 CssClass="txtStyle"  Font-Names="Arial" MaxLength="1000" 

ValidationGroup="Valtxt" TabIndex="2" Rows="4"></asp:TextBox> <asp:RegularExpressionValidator ID="regValSummary" runat="server" ControlToValidate="txtSummary"

Display="Dynamic" ValidationExpression="[^<>&#!]*"

ValidationGroup="Valtxt">Invalid characters(^<>&#!) are not allowed.

  </asp:RegularExpressionValidator>   <asp:RequiredFieldValidator ID="reqvalSummary"  

runat="server"

ControlToValidate="txtSummary"

ErrorMessage="Summary is required"

ValidationGroup="Valtxt"

Display="Dynamic">

</asp:RequiredFieldValidator>

can anyone sees the problem???
