mshtml HTMLFormElement events

[Sunny]

Hi all,
dev. env.: VS.Net2003/C#

I have a windows form application with web browser control. I need to
capture the onsubmit event of the forms in the document in order to get
the values and log them.

I have tried this:

1.

this.current_pa ge = this.mydoc.Docu ment as mshtml.HTMLDocu mentClass;

if (this.current_p age != null)
{
mshtml.IHTMLEle mentCollection _forms = this.current_pa ge.forms;

foreach (mshtml.IHTMLFo rmElement _form in _forms)
{
((mshtml.HTMLFo rmElementEvents 2_Event)_form). onsubmit +=
new mshtml.HTMLForm ElementEvents2_ onsubmitEventHa ndler
(MyDoc_onsubmit );
}
}

2.
<same, just diff. foreach>
foreach (mshtml.HTMLFor mElementClass _form in this.forms)
{
_form.HTMLFormE lementEvents2_E vent_onsubmit +=
new mshtml.HTMLForm ElementEvents2_ onsubmitEventHa ndler
(MyDoc_onsubmit );
.....

And there are 2 articles on codeproject.com , they do not work also.

And ... no success. There is no exceprions, everything passes, but after
that the form submition on the page is blocked, even the submit button
does not work.

I have tried to go around this and to use BeforeNavigate2 event of the
browser (it works) and to examine if there is postdata. But in that case
I'll loose forms which has GET method.

Please, any help will be highly appreciated.

Thanks
Sunny

Hi Sunny,

You can set break point in the onsubmitEventHa ndler to find if this method
was called.

Hi Jeffrey,

Thanks for the suggestion. I have already done this before I post. I'm
stating that it is not called, and I mean it.

Thanks
Sunny

Hi Sunny,

Sorry for letting you wait so long.
I still did not figure out where is the problem. I have called some
colleague to handle this issue.
We will reply you ASAP.

Hello Sunny,

I tried the code below:

private void DocumentComplet e(object sender,
AxSHDocVw.DWebB rowserEvents2_D ocumentComplete Event e)
{
doc = (mshtml.HTMLDoc ument)axWebBrow ser1.Document;
foreach (mshtml.IHTMLFo rmElement cform in doc.forms)
{
mshtml.HTMLForm ElementEvents_E vent iEvent;
iEvent = (mshtml.HTMLFor mElementEvents_ Event) cform;
iEvent.onsubmit += new
mshtml.HTMLForm ElementEvents_o nsubmitEventHan dler(OnSubmitEv entHandler);

}

}

And was not able to sink the onsubmit event either. I was able to sink
other form element events however so this really is telling me that we may
be looking at a possible bug. For a workaround have you considered
sinking the onclick event of the submit button on the form? This should
accomplish the same thing.

Hello Ariel,
thanks for the post.
Yes, it seems that it is a bug, but can you provide me some more info
where is it - in the mshtml by itself, or in the wrapper for .Net?

I have solved the problem by capturing the BeforeNavigate2 event, and
examining Post == null of the provided event args.

But this, like sinking to the click event is half of the work.

If you hook to BeforeNavigate2 , you will miss the GET method forms.
And if you sink to the onclick event, you are not sure that the form is
submitted, because it may have some validation, and not always
submitted.

I'll be glad to hear about the progress in that direction.

Thanks
Sunny

Is there any solution for the above mentioned issue? I am very
interested in the solution as I got into the same issue where the submit
button is completely disabled if a onsubmit event handler is attached to
the form.

I appreciate any help.
