Why does button’s click subroutine not execute when RequiredFieldValidator is false?

I’ve got a simple page that should display the string “OK” when the user clicks the button. It works fine untill I put a RequiredFieldValidator on the page. Now it seems like there is an implicit conditional in the source code that prevents the “OK” from being displayed unless the text box has text in it. I put no such conditional in the code; why is it behaving like this?

<%@ Page Language="VB" AutoEventWireup="false" CodeFile="pageIsValidTest.aspx.vb" Inherits="pageIsValidTest" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml" >
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>
    <form id="form1" runat="server">
    <div>
         Textbox:
        <asp:TextBox ID="TextBox" runat="server"></asp:TextBox>
        <asp:RequiredFieldValidator ID="RequiredFieldValidator1" runat="server" ControlToValidate="TextBox"
            ErrorMessage="enter text"></asp:RequiredFieldValidator><br />
        <asp:Button ID="Button1" runat="server" Text="Button" /><br />
        Label:
        <asp:Label ID="Label" runat="server"></asp:Label></div>
    </form>
</body>
</html>

Partial Class pageIsValidTest
    Inherits System.Web.UI.Page

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
        Label.Text = "OK"
    End Sub
End Class

That is because the RequiredFieldValidator has the ControlToValidate set to the text box. It is working as it should, if no text is in the ControlToValidate the RequiredFieldValidator will prevent your server side code from running.

Thanks! Didn’t mention that in the book I’m using so I was confused.

But then what is the point of Page.IsValid? If the server side code will only run if all Validators are true then it seems that it would be impossible to get a false Page.IsValid…

What if I want server side code to do something if the form isn't valid, is there a way to override this behavior?

You can change the "Causesvalidation" of your button to "False" , so it will work without fire the Validators.
i hope it help you.

Thanks you for the response but not quite what I am looking for. I’m looking for a way to run the source code and within that source code programmatically determine if the page is valid (meaning a validaters = true) and do something it is and something else if its not.

ok. But you must be more explicit,ex: what are you doing in the page before you do that request?

Page.IsValid is used to check the validation status at server side. Validation control uses JS by default to do the validation. Since JS is not reliable, ASP.NET does server side validations also to make sure validation logic is not bypassed and set the IsValid flag. So before you continue with your action, check the page is valid. Something like

If(this.IsValid)
   // continue

When validator controls are added, by default the validation will happen at the client side. So validating programatically at server side is pointless as form will not postback if there are validation errors. To do the validations on server, you have to disable client side validations first. Set the EnableClientScript property of the validation control to false.

Page class exposes a Validators[^] collection where you can iterate and call Validate() method on each validator to perform the validation. Check the IsValid property to get the status of validation.

I think I got it now. So if I leave EnableClientScript as true for all validators the code in the source code will only run if all validators are true; the only reason to put Page.IsValid conditional in the source code in this case would be to make sure that the form elements are actually valid and some how the client side validation wasn’t erroneous or by-passed by a user.

If I wanted to do a source code conditional based on form element validity I should set EnableClientScript to false so that the source code will still run even if the user enters in invalid entries.

Thanks all, M

Hi,
I need to get total size of sessions in my application, I enabled the trace for a page, but it didn't show anything about size of sessions.
How can I get it?

That'd odd. Why do you want to do that? You can't calculate the actual size of objects.

did you debug your code?
What properties are set in aspx page for ModalPopup?

In Word you can only store 2 bytes. That is why I use Writer.

can't you add a button to your page with visible=false and set that as targetcontrolid ?

Eventhough the button visible is set to false or true, the button willnot be visible on the page. so there is no problem with Button.

i don't think the problem is with Button(visible=true or visible=false).

Need for me is how to set the tabindex.
