Submit form after asp:RegularExpressionValidator check form valid?

Question

I have a form with this markup:

<asp:TextBox ID="txtMeMail" runat="server" Width="250px" ToolTip="error"></asp:TextBox>
<asp:RegularExpressionValidator CssClass="mandatory msg" ID="RegularExpressionValidator1" runat="server" Display="Dynamic" ValidationGroup="validEmail" ValidationExpression="\w+([-+.]\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*" ControlToValidate="txtMeMail" ErrorMessage="error" EnableClientScript="true" />
<button class="button noMarginLeft" runat="server" validationgroup="validEmail" accesskey="S" id="btnSave" onserverclick="BtnSave_Click" value="Page.FIUserEdit.SaveButton.Label">
    <asp:Label runat="server" Text="label"></asp:Label>
</button>

When I input "abc" and remove the focus from the text box, the invalid email message shows up. After that, I correct the text box with a valid email and I keep the focus on the text box, then I click the submit button. The validation message disappears but the form does not submit.

Is there any way to validate and then submit the form?

Try using

<asp:Button class="button noMarginLeft" runat="server" ValidationGroup="validEmail" accesskey="S" ID="btnSave" OnServerClick="BtnSave_Click" value="Page.FIUserEdit.SaveButton.Label" />

The problem is that you use the ordinary html Button tag. Although it can work it is not recommended because you lose functionality, see How can I use the button tag with ASP.NET?

If you do want content inside the button then use the LinkButton.

It works if you replace `OnServerClick` by `OnClick`. :-) – ConnorsFan Aug 03 '16 at 13:50
If I try that the button still does a postback even when the email is invalid. – VDWWD Aug 03 '16 at 13:55
still not working, I debug the javascript and see that on change event of the text box return true, and the submit was not call. – Phan Đức Bình Aug 04 '16 at 02:18
Think I find out the root cause was when the validate message show up, it make the submit button moving, and my click not on the button. – Phan Đức Bình Aug 04 '16 at 02:40
