AJAX and required field validators

[beaniebear]

Hi,

I have an update panel with a text box and a button.

I have put a required field validator on the text box. When the button is clicked it is not doing the validation and posting the form even when there is nothing in the text box.

Any help would be much appreciated, thanks.

Make sure CausesValidation on the Button is NOT set to false:

<asp:Button ID="Button1" runat="server" Text="ValidateTextBox1" CausesValidation="true" />
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>
<asp:RequiredFieldValidator ID="rfvTextBox1" runat="server" 
            ControlToValidate="TextBox1" Display="Static" ErrorMessage="Required">
</asp:RequiredFieldValidator>

I started the page again from scratch and it all worked the second time. I will remember this tip for future though. Thanks.
