Hi there,

for my completely database based form I need to do scripting just BEFORE the
form is submitted. I tried the following:

- register for the onClick() event of a submit button
--> calls the registered function AFTER the submit action
- register for the onSubmitRequest() event
--> forces me to implement the whole submit action myself. Explicitly
calling XDocument.Submit() out of this function is not allowed.

All I want is to add some additional action before the usual database
update. How can I do that?

Thanks in advance,
Jörn

I think you've pretty much answered your own question by coming up with the
second solution. :)

You need to write code in the OnSubmitRequest() event handler. At the end of
the event handler, use

eventObj.ReturnStatus = true;

to indicate success. Before this line of code you can write code to submit
changes to the database with

XDocument.DataAdapters["Main connection"].Submit();

where "Main connection" is the name of the data connection to the database.
You must/cannot use XDocument.Submit() to submit the form; but you already
discovered this. And before this line you can write your code that must run
before the submit takes place.

Thank you!

> XDocument.DataAdapters["Main connection"].Submit();

That did the trick.
Unfortunately I cannot find the Submit() function in the online
documentation anywhere, even now that I know it's there.

Again, thank you very much,
Jörn
