Hi, I'm having trouble solving a problem in asp.net.
I have a web application that have four buttons which is link to a Sql server database where I can Add, Get, Update, Delete clients. I have set CausesValidation to true for the Add button and the Update button on all textboxes (ID, FirstName, LastName, Email, Confirm Email). However, each time I retrieve a client and try to update some of the fields, the confirm email validation comes up with the RequiredFieldValidator error "Confirmation email required!". My Confirm Email consist of two validation, a RequiredFieldValidator and a CompareValidator.
How can I disable this RequiredFieldValidator error from popping up for the Update button only?
My database consist of ID, FirstName, LastName, Email. Thanks

Thanks, but I do need the Require validation for my Add button. If I remove it I can add any clients without confirming their email.

Change your Required Field Validator on that control to a custom validator. You can then either validate on the back-end, depending on which button was pressed or, better, add a custom JavaScript validation function. If you then use a page global flag which you set using a Javascript OnClientClick function on your update button. You can then check this flag in your custom validation function, returning true when set and checking your text box if not (returning the appropriate state.)

Note that you can still validate on both client and server side if that is required.

Typically, if you need different sets of validation for different buttons on the same page, the simplest solution is to use validation groups:

Basically, you would choose a meaningful group name, and set it as the ValidationGroup on the validator controls and the buttons which should trigger the validators in that group.

However, you would need to duplicate the validator controls which apply to both groups.

ASP.NET

<asp:TextBox id="Email" runat="server" ... />
<asp:RequiredFieldValidator runat="server" ControlToValidate="Email" ValidationGroup="Add" ... />
<asp:RequiredFieldValidator runat="server" ControlToValidate="Email" ValidationGroup="Update" ... />

<asp:TextBox id="ConfirmEmail" runat="server" ... />
<asp:RequiredFieldValidator runat="server" ControlToValidate="ConfirmEmail" ValidationGroup="Add" ... />
<%-- NB: Not required for the "Update" group --%>

<asp:Button runat="server" Text="Add" ValidationGroup="Add" ... />
<asp:Button runat="server" Text="Update" ValidationGroup="Update" ... />
