How do I get the RegularExpressionValidator to work with a gridview during 
an update?  The error message displays briefly -- very briefly, you don't 
even see it unless you are stepping through the code, but the update 
continues as if nothing happened.  If I have to use the RowUpdating event, 
then what's the purpose of the validator?  It appears the 
requiredfieldvalidator works, but not the regularexpressionvalidator.  This 
is my gridview template:

<asp:TemplateField HeaderText="Preferred">

<EditItemTemplate>

<asp:TextBox ID="txtPreferredPhone" runat="server" Text='<%# 
Bind("PhoneNumber") %>' ></asp:TextBox>

<asp:RegularExpressionValidator ControlToValidate="txtPreferredPhone" 
id="valPhoneNumbers" runat="server" ErrorMessage="Please use phone number 
format (111-111-1111)" ToolTip="111-111-1111" 
ValidationExpression="((\(\d{3}\) ?)|(\d{3}-))?\d{3}-\d{4}" 
ValidationGroup="PhoneNumberValidator" Display="Dynamic">Incorrect 
format!</asp:RegularExpressionValidator>

</EditItemTemplate>

<ItemTemplate>

<asp:Label ID="Label1" runat="server" Text='<%# Bind("[Preferred #]") 
%>'></asp:Label>

</ItemTemplate>

</asp:TemplateField>

Hi,

do you also do Page.IsValid check in code (yes it needs to be done in order 
to ensure nothing passes server-side validation)?

Does the regexvalidator catch the error at client-side at all? (Do you have 
ValidationSummay on the Page and does it show anything)?
