Dropdown box - which event handler to use ?

I am having trouble with setting the readonly property (via Javascript) of the adjacent textbox to my dropdown box when the index value is a certain number.
I tried using MouseUp, MouseDown, and even OnBlur....but the readonly does not seem to be getting set to true or false consistently.
Could this be a timing issue ? The textbox that I am trying to control is the next tab-order control in the list of controls for this page.
This same logic is working fine in the MouseUp event handler for check boxes. So I am just wondering if this is a bug or must my implementation change to accomodate dropdown boxes ? For instance, should I move the logic to the Enter event handler of the textbox instead ? Can a control's own eventhandler set itself to readonly when it is the active form field ?

After tons and tons of testing time, I've come to the conclusion that dropdowns are totally buggy in 11.0.07 release of Acrobat Pro.
Even if you set the "commit values immediately", you get the PRIOR selected item's value as the event value, not the CURRENT one.
This occurs in a Validate event handler script. I have not been able to use any other event handlers for a dropdown except the OnBlur....and then, for my purposes, IT'S TOO LATE !!!
This is totally worthless as I need to setFocus() and set fields to readonly based on the immediate dropdown offset or face value.

Event handler when using partial page refresh ?

Hi
I have a calendar, which uses partial page refresh. The problem is how to make javascript wait until the calendar has loaded and then do some updates on the calendar (after the user has pressed the next button that runs apex.widget.calendar.ajax_calendar('S','next');, for example ). I thought I could add "onreadystatechange" (or onload) event handler to the calendar like this: onreadystatechange="checkState()", where the function would check the state and if ready then do the updates. This doesn't work. Could somebody please tell me why not ?

Hi,
It seems that ajax calendar missing event apexafterrefresh.
I do not know is this "bug" or just feature.
That event would be useful to your case , if I understand correct what you looking for.
For workaround , you can over write original function by placing this to calendar region footer
<script>
apex.widget.calendar.ajax_calendar=function(p_calendar_type, p_calendar_action, p_calendar_date, p_calendar_end_date){
var l_cal_type_field = $v('p_cal_type_field_id');
var l_cal_date_field = $v('p_cal_date_field_id');
var l_cal_end_date_field = $v('p_cal_end_date_field_id');
var l_cal_id = $v('p_calendar_id');
var l_calendar_region = 'calendar' + l_cal_id;
if ( p_calendar_type != 'C' ){
$s(l_cal_date_field,$v('p_calendar_date'));
}else{
if ( $v(l_cal_date_field) == '' ) {
   $s(l_cal_date_field,$v('p_calendar_date'));
if ( $v(l_cal_end_date_field) == '' ) {
   $s(l_cal_end_date_field,$v('p_calendar_end_date'));
// create and apex.ajax.widget object
var a = new apex.ajax.widget('calendar',function(){
/* start the return function */
if(p.readyState == 1){
   document.body.style.cursor = "wait";
}else if(p.readyState == 2){
}else if(p.readyState == 3){
}else if(p.readyState == 4){
   $x(l_calendar_region).innerHTML = p.responseText ;
   $s(l_cal_date_field,$v('p_calendar_date'));
   if (p_calendar_type == 'C') $s(l_cal_end_date_field,$v('p_calendar_end_date'));
   document.body.style.cursor = "";
/* DO HERE THINGS AFTER CALENDAR REFRESH */
}else{return false;}
// code for next,previous and today
if (p_calendar_type == 'S'){
p_calendar_type = $v('p_calendar_type');
}else{
$s(l_cal_type_field,p_calendar_type);
a.ajax.addParam('p_widget_mod',p_calendar_type);
a.ajax.addParam('p_widget_action',p_calendar_action);
a.ajax.addParam('x01',l_cal_id);
var lDate = (!!p_calendar_date && p_calendar_date !== '')?p_calendar_date:$v(l_cal_date_field);
if (p_calendar_type == 'C') {
var lendDate = (!!p_calendar_end_date && p_calendar_end_date !== '')?p_calendar_end_date:$v(l_cal_end_date_field);
a.ajax.add(l_cal_date_field,lDate);
if (p_calendar_type == 'C') a.ajax.add(l_cal_end_date_field,lendDate);
a.ajax.addParam('x02',lDate);
if (p_calendar_type == 'C') a.ajax.addParam('x05',lendDate);
a.ajax.add(l_cal_type_field,p_calendar_type);
a._get();
</script>Where I have comment *"do here things after calendar refresh"*, you can hook own scripts.
Of course this is not best way, but might help you till ajax calendar support dynamic actions fully

Event handler method

Hi all,
I want to know the significance of creating event handler method in Class builder.
and how it can be used at the time of event trigger.( Is it called automatically or programmer need to call it explicitly in the program.)
Thanks,
Sushant singh

Hi Sushant,
1. In ABAP Objects, triggering and handling an event means that certain methods act as triggers and trigger events, to which other methods - the handlers - react. This means that the handler methods are executed when the event occurs.
2.To trigger an event, a class must
Declare the event in its declaration part
Trigger the event in one of its methods
3.You declare events in the declaration part of a class or in an interface. To declare instance events, use the following statement:
EVENTS evt EXPORTING... VALUE(e1 e2 ...) TYPE type [OPTIONAL]..
4. An instance event in a class can be triggered by any instance method in the class. Static events can be triggered by any method. However, static methods can only trigger static events. To trigger an event in a method, use the following statement:
RAISE EVENT evt EXPORTING e1 = f1 e2 = f2 ...
5. Events are handled using special methods. To handle an event, a method must
be defined as an event handler method for that event
be registered at runtime for the event.
Declaring Event Handler Methods
Any class can contain event handler methods for events from other classes. You can, of course, also define event handler methods in the same class as the event itself. To declare an event handler method, use the following statement:
METHODS meth FOR EVENT evt OF cif IMPORTING e1 e2 ...
6. Registering Event Handler Methods
To allow an event handler method to react to an event, you must determine at runtime the trigger to which it is to react. You can do this with the following statement:
SET HANDLER h1 h2 ... [FOR]...
It links a list of handler methods with corresponding trigger methods. There are four different types of event.
7. Timing of Event Handling
After the RAISE EVENTstatement, all registered handler methods are executed before the next statement is processed (synchronous event handling). If a handler method itself triggers events, its handler methods are executed before the original handler method continues. To avoid the possibility of endless recursion, events may currently only be nested 64 deep.
Handler methods are executed in the order in which they were registered. Since event handlers are registered dynamically, you should not assume that they will be processed in a particular order. Instead, you should program as though all event handlers will be executed simultaneously.
Reward if useful.

Inserting dropdown box

Dear all,
it is a business requirement to be able to chose between different seasons within my company. Therefore I need a dropdown box, which is "connected" to the prompt and refers on a variable (not like a usual Excel dropdown, which is more static with pre-defined selections). This means, it should be dynamic and if I change the season within the dropdown, it should also change it in the prompt and therefore change the workbook.
As far as I know this was also possible in BEx Analyzer.
Can anyone please give me some advice?
Thanks in advance!
Kind regards
Dominik Drebinger

Hi Dominik,
I had a similar problem where the Finance user wanted to view their report by cost centre node without having to use the prompts screen so that the report did not have to refresh each time.
This method allows you to refresh data only once and then you can toggle the data you want to view via the Excel list functionality.
Hope this helps
Using Excel Lists
instead of SAPSetFilter Component
Using Excel lists instead of the SAPSetFilterComponent will
enable you to toggle your report without having to refresh your report each
time. For example if you would like to view each of your cost centre nodes on
one report without having to refresh.
Step 1
Ensure your data source includes all of the centres as a
Column heading. Expand your centres to the correct level .

Step 4
On the face of your report create a drop down list in Cell
A1. On the MS Excel Ribbon select Data, Then select data validation.
In the allow box select list and choose the list you created
in Step 2 as the Source.
Your List will look like this
Step 5
In the cell next to your list (cell A2), create a vlookup to
find the cell that you created in Step 3.
=VLOOKUP(D1,Parameters!$A$15:$c$19,3,FALSE)
Step 6
Now reference the vlooked up cell (Cell A2) you created in
Step 5 in your SAPGetData formula and lock the cell using as follows ,$A$2. If
you have referenced your measure type, and GL account (Please refer to manual
on referencing your own you can drag the formula across your report.
SAPGetData("DS_1",D$4,$B8,$A$2)

Using a dropdown box to change the specified value of a radio button?

I have a form that generates the body text for an email.
First there is a dropdown box in which the choices are either "red" or "blue"
Further down the page, there is a radiobutton list with 2 items "available" and "unavailable".
The specified values for these items (as defined on the binding tab) are "have blue hats" or "do not have blue hats".
This value is concatenated in the email body textfield which is to be copied by the user to an email body:
Concat("Dear", NameField, "," We ", RadioButtonList, " today. ") // Dear Persons Name, We have blue hats today.
Is there any way to change the value of the selected radio button based on the selected dropdown choice?
So if the user selected "red" in the dropdown field, the radio button values could become "have red hats" or "do not have red hats"?
Or perhaps there is a better way from the start?
Thanks!

Ok, so now I've done that...
But is there a way to change that value with another field (ie when a user chooses "red" or "blue" in a dropdown box) so that the concatenated message reflects both the users choice of color and the availibility?
I'm guessing I should probably use an intermediary text box and put
InterText.rawValue = Concat ("We have ', dropdown1, " hats today") in the change event of the available radio button and:
InterText.rawValue = Concat ("We do not have ', dropdown1, " hats today") in the change event of the unavailable radio button.
then concatenate that box in the final textbox.

I have a dropDownBox which has a database table containing artist names attached to it. I accomplished this by dragging the artist table onto the dropDownBox.
I created a dataTable and dragged the table, Inventory, that contains a list of all the prints for an artist. The primary key for this table is the stock number, The primary key for the artist table is the artist code.
I would like to be able to select an artist from the dropDownBox and have only the fineart related to that artist displayed in the dataTable.
I followed the example in the tutorial, but its not working. I noticed that the way the master/detail relationship is done in the Application Model is totally different. I am new to java and web programming, so the way it was done in the application model I don't understand enough to replicate.
If you look at my original post, I provided the error messages and a copy of my code. This application is a school project which needs to be turned in by Tuesday of this coming week, I would appreciate any help. Thanks.

How to use 2 Dropdown box in webapplication for date range selection

Dear all,
I am working on a report that will show 2 drop down boxes. These should be used as a date range.
This works fine if I use 2 variables as a date range on 0CALYEAR. However I dont want the user to fill in the dates but selecting the dates with 2 drop down boxes.
I cannot manage to get this to work. I saw some comments about user exits in the forum but I cannot figure it out if there is an easier way.
Could you give me an idea of what to do?
Thanks a lot,
Andreas

Hi,
If you want the user to select the date directly rather than entering, you need not to have a dropdown menu in WAD. Directly go to the query which you have selected for the object in WAD, there create a variable with calendar. Put it mandatory, so that the user selection of the date will be mandatory. The variable will be automatically be available when you execute the template inn the browser.
Assign points if this helps u.

Koundinya.

Event handler switch creation (for repeated use )

Im creating a hyperterminal like application which reads from serial port and writes into serial port.
The reading and writing works almost fine..I also wants to create some custom "Key controls" that will send some prestored commands to the serial port.
I currently implemented two commands "ESC" and "FLASH " in the Key controls menu..
I want to send these commands ESC and FLASH each time i click a button in the menu.
I used event handler for it..and put the event handler inside an always running while loop.
But the problem is I can send only these commands only for one time during execution.
Repeated pressing of switches doesnt cause any effects..
Can somebody help please???
Im using labview 6.1. If u modify VIs using higher versions i cant open here..kindly include a jpg screenshot inthat case.
Thanking you.
Stephen.

Hi Stephen,
in LV7.1 your events will be executed whenever I press one of the according switches...
Notes:
-Don't make several event structures. Instead make one event structure with several event cases. Read the context help for the event structure!
-I would suggest to set the mechanical action of both switches to "latch when pressed" instead of "switch..." to give a feedback to the user as the switch will be reset after reading it...
-Generally be more styleguide-conform! Use right-click on terminals to create controls/constants to avoid coercion dots (spot the red colored dots in the image?). Make error in/out in the lower left/right of the connector pattern. Avoid block diagrams larger than the screen (or what kind of monitor do you use?).
Edited:
Sorry for weird display. I have to get used to the new image gallery feature of the forum (and will use "image to the left" only on rare conditions). Btw. the preview looks different to the actual post
