No, I did not set any validation group to the validators. Do I need to do this to get the summary validator to work as a showmessagebox?

Question
validation summary control
I have a simple webform that uses the validation controls. I have disabled the validation client-side and set the server side validation to be enabled with I call a method EnableValidators().
All this works fine except when I try to add a summaryvalidation control. I can't get the showmessagebox to work for the summary control? I've set showsummary to false and showmessagebox to true.
Here is how I implement the EnableValidators method:
protected void EnableValidators(bool toggle)
{
valcConfirmPassword.Enable
valeEmail.Enabled = toggle;
valrCity.Enabled = toggle;
valrComments.Enabled = toggle;
valrEmail.Enabled = toggle;
valrPalindrome.Enabled = toggle;
valrPassword.Enabled = toggle;
valrReportDate.Enabled = toggle;
valrUsername.Enabled = toggle;
valxPalindrome.Enabled = toggle;
valxPhone.Enabled = toggle;
valxTerms.Enabled = toggle;
valgReportDate.Enabled = toggle;
valxComments.Enabled = toggle;
valxCity.Enabled = toggle;
vals.Enabled = toggle;
}
Then on my button click event handler:
protected void Button1_Click(object sender, EventArgs e)
{
EnableValidators(true);
Page.Validate();
if (Page.IsValid)
{
lblPageValidationStatus.Te
}
else
{
lblPageValidationStatus.Te
}
}
Here is the summary control on the aspx page:
<asp:ValidationSummary ID="vals" runat="server" DisplayMode="List" Enabled="False"
ShowMessageBox="True" ShowSummary="False" />
So, what I'm trying to accomplish is show the message box summary as a popup when the user clicks the submit button as well as show the regular error messages for each control (that already works fine). Only the summaryvalidation control showmessagebox is not working.
Thanks for any help.

it could be that the summary is disabled on first render. since it is only enabled when the Button1_Click event handler is fired, unless the Button1_Click causes the postback and reaches the said event handler, the validator summary is disabled. That is from the client side point of view, it should not validate anything.
hope this makes sense and helps
Okay, I'm still kind of fussy on the page event lifecycle, so forgive my question if I don't understand correctly.
If I enable summaryvalidation control and don't set it to enabled in the code behind then it still doesn't show the popup.
Is that what you mean? Basically, I removed the line: vals.Enabled = toggle.
and changed the control properties to:
<asp:ValidationSummary ID="vals" runat="server" DisplayMode="List" Enabled="True"
ShowMessageBox="True" ShowSummary="False" />
Is this what you meant?
Yes, that's what i meant. If in the *.aspx the validationSummary is enabled and not disabled during the serving of the page (rendering/loading) then the validationSummary should show the alert box.
Is there any chance that you disable it in the code behind while serving/rendering the page?
You seem to be doing it right so it could be possible that in some other part of your code, you disable it or change it's showmessagebox property or change it's validationgroup.
Hi steelheart38,
Thanks for the clarification. I must be disabling the summary control somewhere, but I don't see it? It is probably staring me right in the face.

Thanks for your help.
Can you try setting these values in all your validators:
EnableClientScript="True"
Enabled="True"
I'm not sure of any other consideration you have but i believe the problem is that all validators are disabled when sent to the client so ValidationSummary really has nothing to validate in the client side. If i'm not mistaken, the alert/message box feature will only work if EnableClientScript is set to true.

Did you set any validationgroup to your validators? If so, set it to the validationsummary too.
