button attributes disable validation

P: n/a
I am trying to use both validation controls and to add submit button
attributes, but when I add the button attributes, the javascript fpr the
validation controls is no longer created for the page. How can I use both?

Thank you,

Hi Tim,

If I understand you correctly, you are trying to add javascript to the
submit button and it breaks client-side validation. If that's the case, see
this article: http://aspalliance.com/699 in the topic "Messageboxes and
Validation". While it shows how to add a confirm prompt, you can use the
technique shown to add any javascript to a button.

Peter,

Thank you for this information. It has shown me how to invoke the
validation objects when the submit button is pressed as part of the server
side event handler - and it appears that the validation should be added to
server-side handling especially for browsers that cannot handle client-side
validation.

I would still be interested in knowing how to run the client-side validation
in conjunction with the confirm feature that I added to my submit button to
avoid a postback.

Regards,

Tim

Hi Peter,

I also found out that one can selectively enable and disable client side
validation merely by setting the enable flag of the validation control to
true or false. I was able to take advantage of that in my code to simplify
validation for all my validation controls by creating the two following
methods:

// Returns true if validation succeeds for the given validation control, or,

// if the control is not enabled (in which case no validation should occur)

private bool IsValidControl(BaseValidator control)

{

if (!control.Enabled)

{

return true;

}

control.Validate();

return (control.IsValid);

}

private bool IsValidForm()

{

bool valid = true;

valid &= IsValidControl(ReqValUserID);

valid &= IsValidControl(RegexUserID);

valid &= IsValidControl(ReqValFirstName);

valid &= IsValidControl(RegexFirstName);

valid &= IsValidControl(RegexMiddleInitial);

valid &= IsValidControl(ReqValLastName);

valid &= IsValidControl(RegexLastName);

valid &= IsValidControl(ReqValEmail);

valid &= IsValidControl(RegexEmail);

valid &= IsValidControl(ReqValPhone);

valid &= IsValidControl(RegexPhone);

valid &= IsValidControl(ReqValNotes);

valid &= IsValidControl(ReqValReject);

return valid;

}

Finally, I invoked the IsValidForm() method in my submit button onclick
handler as follows:

if (!IsValidForm())

{

return;

}

I'm confused by this. I pointed you to a portion of my article that
specifically handles client-side confirm that either permits or blocks
submitting the page.

FYI: This is easier in my Professional Validation And More. I give you
properties to create confirm messages and run the confirm either before or
after page validation runs on the client side. I also give you a hook to add
any other javascript you want into the page validation process so you can
stop the page from submitting for your own reasons.
