asp.net server side debugging

I'm new to asp.net. I'm trying to follow the tutorial walkthroughs and have
got a few done. Now I'm doing the one about validating input, and I've run
into some problems.

In particular, I am watching very intermittent behavior of my ASP page.

when I execute:

protected void buttonSubmit_Click(object sender, EventArgs e)
{
if(Page.IsValid) {
labelMessage.Text = "Your reservation has been processed.";
}
else
{
labelMessage.Text = "Page is not valid.";
}
}

the Page.IsValid is returning true even when it has produced errors that the
Validators have caught.

2ndly the Validator for ONE of my controls is randomly incorrect.

So, how might I debug this? The client side is not where MY PROBLEMS lie.
I need
to debug the SERVER side to understand if my properties on the validators
are not correct.

Is there caching of prior data going on that I'm not aware of?
How do I go about cleaning this out?

How do I debug this odd/frustrating behavior?

TIA

What kinds of validators are you using? If you have custom validators, you
might have an issue there, based on how they are set up.

Personally, I run data through a secondary validation on the server side to
be safe. I like having the validation in a business component, as it is
portable to other forms of application faceplates (like Windows Forms and
WPF/Silverlight). I cannot do this if all of the validation is buried in the
ASP.NET code.

Thanks for the reply, the validator I'm using is just the one from the
tutorial...
I forced some print statements to be dumped, and that just confirmed that
values are being cached, so I'm out of the looney bin.

I don't understand the caching though. If I fill in a form , then submit
it, then edit it and submit it again I don't find that the result is
processed correctly.

I guess I'm don't understand the execution model and when things get
processed.
Maybe a couple pointers on that would be informative.

Hi,

To learn the validation controls I suggest you follow this tutorial:

http://quickstarts.asp.net/QuickStar...lidation/defau
lt.aspx

From the code you provided it seems you're not using cache. So I'm not sure
if the cache will cause this problem. Could you send me a demo project that
can reproduce this issue? My email is v-******@microsoft.com. I'll test it
and see what the problem is.

Hello Larry,

Thanks for your code.

==================================================

2ndly the Validator for ONE of my controls is randomly incorrect.
==================================================

Do you mean the RangeValidator not work properly? From the code that you
sent me via email we can see:
<asp:RangeValidator ID="valNumInParty" runat="server"
ControlToValidate="textNumberInParty" Display="Dynamic"
ErrorMessage="1 to 20 plese" MaximumValue="20" MinimumValue="1"
ValidationGroup="AllValidators">num in party bad
</asp:RangeValidator>

By default the type of RangeValidator is String so some input such as 3
will be considered as invalid even though the MaximunValue is "20" and the
MinimumValue is "1". To get it work we need to set the type as integer or
double based on your requirement:

<asp:RangeValidator ID="valNumInParty" runat="server" Type="Integer"
ControlToValidate="textNumberInParty" Display="Dynamic"
ErrorMessage="1 to 20 plese" MaximumValue="20" MinimumValue="1"
ValidationGroup="AllValidators">num in party bad
</asp:RangeValidator>

==================================================

In particular, I am watching very intermittent behavior of my ASP page.

when I execute:

protected void buttonSubmit_Click(object sender, EventArgs e)
{
if(Page.IsValid) {
labelMessage.Text = "Your reservation has been processed.";
}
else
{
labelMessage.Text = "Page is not valid.";
}
}

the Page.IsValid is returning true even when it has produced errors that
the
Validators have caught.
==================================================

I cannot reproduce this issue. What I can see is the client validation for
CustomValidator1 is conflict with its server side validation.From the
following javascript we can see the input 1/1/1985 will be accepted:
<script language="javascript">
function validateDate(oSrc, args)
{
var iDay, iMonth, iYear;
var arrValues;
arrValues = args.Value.split("/");
iMonth = arrValues[0];
iDay = arrValues[1];
iYear = arrValues[2];

var testDate = new Date(iYear, iMonth - 1, iDay);
if ((testDate.getDate() != iDay) ||
(testDate.getMonth() != iMonth - 1) ||
(testDate.getFullYear() != iYear))
{
args.IsValid = false;
return;
}

return true;
}</script>

However,the server side validation only accepts the date format such as
01/01/1985:

protected void CustomValidator1_ServerValidate(object source,
ServerValidateEventArgs args)
{
try {
DateTime.ParseExact(args.Value, "d", CultureInfo.InvariantCulture);
//Note, use CultureInfo.InvariantCulture instead of null as the third
parameter.
args.IsValid = true;
}
catch {
args.IsValid = false;
}

So I'm not sure what should be the valid input. Could you clarify your
requirement? If you still have this problem please send me a demo and tell
me how to reproduce this issue in detail.

==================================================
PS. Why does the project end up in MyDocs...? and the sources in another
dir?
==================================================

You're creating a Web Site instead of a Web Application project. The Web
Site will keep the page files and the sln file separate.

Please let me know if you need further assistance.
