Setting e.newValues with protected session variables

[Scholin]

I know this should be very simple setting a field with a new value using OnInitialValueCalculate Event.

No problems using static values but I can't for the life of me figure how to give a field the value of a session.__protected__variable.

For static values you simply use:
e.newValues.fullname="some name"

so what I can't get is something like:
e.newValues.fullname=session.__protected__fullname

I have tried many combinations of "", s_quote, quote, '',etc.

What am I doing wrong? Thank you!!

Re: Setting e.newValues with protected session variables

I just did this on an A5W page, and got the desired results:

<%A5
dim session.__protected__fullname as c = "Michael"
?"session.__protected__fullname = " + session.__protected__fullname + "<br>"

dim e as p
e.newValues.fullname = session.__protected__fullname 
?"e.newValues.fullname = " + e.newValues.fullname + "<br>"
%>

It returned this:

session.__protected__fullname = Michael
e.newValues.fullname = Michael

Re: Setting e.newValues with protected session variables

Steve,

If I declare the variable within the OnInitialValueCalculate then yes I can get the variable to show on the grid field as desired as you described.

However, for some reason this event (as well as the OnGridInitialize event) is not seeing my protected session variables or I am not declaring them properly for the event.

What is interesting is that the a5w page that holds this test grid has a debug area that does correctly display all my protected session variables. So it appears to be an issue with these events not seeing these variables as "I would expect" them to.

Any ideas how I can get these grid events to see these variables?

Micahel,

Try e.newValues.fullname=e.rv.session.__protected__fullname

Notes from the OnPageRedirect event ...

'e.rv - Request Variables (allows you to get at page variables and session variables
'e.rv.Session - session variables.

I am using this syntax to set a session variable named uuid from a grid value named uuid in the OnPageRedirect event ...

e.rv.session="uuid" 'create session variable
e.rv.session.uuid=e.rv.v.r_1.uuid 'set session variable

Bob,

That is the ticket!

V10 has a lot of new things to learn but so far it has been worth it!

Thanks again.

Re: Setting e.newValues with protected session variables

Great ...

I just remembered another tip based on my example of setting a session variable above.

If you are inserting a new record and haven't committed it yet, the row values are referenced with _r as in my example,

e.rv.session="uuid" 'create session variable
e.rv.session.uuid=e.rv.v.r_1.uuid 'set session variable

Apparently V10 adds the _ to the rows of a new record.
When I looked at this variable in Firebug, I could swear it reported a - and not a _. That threw me for a loop.

Re: Setting e.newValues with protected session variables

OK, you would think that if I could follow your example of the OnGridInitialize to set a newValue of my V10 grid with a session protected variable, it would stand to reason that I could figure out how to set a value of an (hidden) up-datable field to equal the protected session variable on either the NEW AfterUpdateRecord event or the old reliable AfterUpdateRecords event, which worked in V9 with a simple:

DataSubmitted.Changed_By = session.__protected__fullname

Now I have tried a lot of variations things like:

e.DataSubmitted.Changed_By=e.rv.session.__protected__fullname

but no go.

Any suggestions?

Thanks!

Re: Setting e.newValues with protected session variables

In V10, a lot of the events use the following format,as in the OnPageRedirect event

function OnPageRedirect as v (e as p)
'*******************************************************************************************************************
'IMPORTANT: This event will only fire if the 'Target Page' property in the 'Update Settings' pane is set to: <Event>
'*******************************************************************************************************************
'This event must set the e.URL property.
'This is the target URL to which the browser will redirect.
'e.rv - Request Variables (allows you to get at page variables and session variables - e.g. e.rv.var1, e.rv.session.sessionvar1)
' as well as all data that was submitted to the server.
'e.rv.Session - session variables. TIP: To set a session variable: e.rv.Session = "myNewSessionVariable"
'Examples:
'e.url = "page1.a5w" 'redirect to another page in your application
'e.url = "http://www.google.com" 'redirect to google.

'To pass data to the target page. (e.g. the 'Firstname' and 'Lastname' variables that the user entered in Row 1 of the Grid)
'e.url = "page1.a5w?firstname=" + e.rv.v.r1.firstname + "&lastname=" + e.rv.v.r2.lastname
e.rv.session="contact_id" ' create session variable to filter report
e.rv.session.contact_id=e.rv.v.r1.id ' set session variable to contact id
e.url="report1.a5w"
end function

My code snippet,in red above, creates a session variable and then sets the session variable to a field in the grid. Notice how I reference the value for the field "id" in the above example in bold red. You must use this new format to reference your fields with this function.

As I mentioned in my previous post, it seems that if the record is new and has not been committed that the row reference values use an underscore as in r_1 as opposed to r1 so be careful here.

You can use Firebug to check these references.

Some also use the following format, as in the AfterUpdateRecords event which use the same format you are used to in V9

function AfterUpdateRecords as v (Args as P, PageVariables as P)
with PageVariables
end with
end function

Re: Setting e.newValues with protected session variables

I know this topic is quite old, but I found it useful for something I was trying to do. I was running into a problem where if all my code was in my A5W page it worked fine, but if I moved some to an AEX file, it did not.

I have an Xbasic function in an AEX file that was setting some session variables and I was running into the problem with the following code.

SomePage.a5w:

[COLOR="#0000FF"]<%a5[/COLOR]
[COLOR="#800080"]' Load AEX file then call the function in MyAEXFile to set session.__protected__someVar[/COLOR]
[COLOR="#008000"]a5w_load_aex([/COLOR]"MyAEXFile.aex"[COLOR="#008000"])  [/COLOR]                                                              
[COLOR="#008000"]SampleFunction([/COLOR]"doggy"[COLOR="#008000"])[/COLOR]                                                                     
[COLOR="#800080"]' Check if the session variable exists and print an appropriate message[/COLOR]
if ([COLOR="#008000"]eval_valid([/COLOR][COLOR="#808080"]"session.__protected__someVar"[/COLOR][COLOR="#008000"])[/COLOR]) then
	?[COLOR="#808080"]"session.__protected__someVar = " [/COLOR]+ session.__protected__someVar
	delete session.__protected__someVar
else
	?[COLOR="#808080"]"someVar undefined."[/COLOR]
end if
[COLOR="#0000FF"]%>[/COLOR]

BROKEN SampleFunction:

FUNCTION SampleFunction AS C (someValue as C)
	delete session.__protected__someVar                ' Delete the variable if it exists.
	dim session.__protected__someVar as C = someValue  ' Set the variable.
END FUNCTION

Using the guidelines here, I changed my function to the following and it works great.

Working SampleFunction:

FUNCTION SampleFunction AS C (someValue as C)
	delete session.__protected__someVar       ' Delete the variable if it exists.
	session = "__protected__someVar"          ' Create the variable.
	session.__protected__someVar = someValue  ' Set the variable.
END FUNCTION

So what I take away from this is that declaring/setting a session variable in an AEX file may not work in the same way as you can set it on an a5w page. Admittedly, the correct way to do it is probably the way that works on both. My point is that with this thread, I was able to learn how to do it and thought I'd pass on what I learned so someone else might learn faster.
