How to call a dynamic URL on 'button press' event, in MVC-based BSP

Hi,
My requirement is as below:
On selecting a row in table view, and pressing a button, I need to open a browser.
The Browser URL depends on the row selected.
The key field from table view, is added at the end of the URL string.
Shortly, I can say that, I am getting a value on row selection & want to pass it to button event.
In Views Section, there are 2 tags- (1)table view & (2)button.
Right now, I have put the code for getting the key field, in DO_HANDLE_DATA method.
In Button's OnClientClick method, I have called the Javascript to open the browser.
If I now write the code to concatenate the key field value to form the dynamic URL in 'OnClick' method,
it will be called only after the browser is opened.
(as OnClick event is executed only after OnClientClick event is executed)
Could anyone please tell me what event (and in which tag) can be used to solve this.
Is there any event which is triggered, as soon as the row is selected, & before the button press event is triggered ?
Would really appreciate responses made to this query.
Thanks,
Nisha Vengal.

Hi Nisha,
The crux of your issue here is that you want to call the event triggered with onClick before calling the event triggered on onClientClick. This can be achieved by the following code in the function called on the onClientClick.
function fn_button()
htmlbSL(this,2,'b_row_selection:onInputProcessing()');
window.open("new_page",target="BLANK");
Here, fn_button is the javascript function called on button click, and b_row_selection is the event triggered on the onClick event of row selection.
Try this out and let us know if it works for you.

Dynamic Action with KeyCode check for ENTER button pressed

Hi,
I want to create a dynamic action which executes if the ENTER button of field P1_NAME is pressed.
I thought about this type of DA:
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.triggeringElement.keyCode == 13
That unfortunately doesn't work! Dynamic action doesn't get executed...
Hope for help! :)
Tobias

I found the solution in my own blog: :)
Event: Key Press
Selection Type: Item(s)
Item(s): P1_NAME
Condition: Javascript expression
Value: this.browserEvent.keyCode == 13

Enter Button Pressed in a TextArea

Greetings folks. I am trying to create a TextArea that with a button attached to its functionality so that each time the button is pressed, the text appearing in the TextArea will be sent. Help would be appreciated.
Note: 5 Nuke dollars are also attached to this topic...

Dear esf2000:
Well, the contents of the textarea are going to be set to a chat area and the code for this has already been taken care of (In a method called sendMessage() )
I have the following code designed for entering the text when one presses the enter button on the keyboard:
_inputField = new JTextArea(4, 50);
_inputField.setBorder(BorderFactory.createLineBorder(Color.black,3));
_inputField.setLineWrap(true);
_inputField.addKeyListener(new KeyAdapter() {
public void keyReleased(KeyEvent e) {
if (e.getKeyCode() == KeyEvent.VK_ENTER) {
if ((_inputField.getText().compareTo("")) != 0) {
sendMessage(_inputField.getText());
_inputField.setText("");
I would like to attch a button to the functionality of it as well. Your input would be appreciated.

Button Pressed event help

The problem is simple, but i will try describe it the most.
I have a button that triggers an event while it's pressed, and the event must continue executing until the button is released (or at last when released it triggers a second event that stops the first).
I had implemented using mouseEvents, but the button can be pressed hitting a key or, even, automatically. Using actionEvents i don't know how i will know when the button is pressed and when it is released. Using changeEvent i don't know which property changed. There is some kind of property maned PRESSED or something alike?
I searched in forum, but i don't find anything. =(

It seems what you are looking for is the "armed" property of the buttons ButtonModel. AFAIK there is no PropertyChangeEvent associated with this property, but when it changes the button will fire a ChangeEvent.
So, you can add a ChangeListener to your button, and in the listener's stateChanged implementation you call isArmed() on the buttons model. Something like this:
    static class ArmedStateListener implements ChangeListener {
        private JButton button;
        private boolean lastArmedState;
        public void register(JButton button) {
            if (this.button != null) {
                this.button.removeChangeListener(this);
            this.button = button;
            lastArmedState = button.getModel().isArmed();
            button.addChangeListener(this);
        public void stateChanged(ChangeEvent e) {
            boolean isArmed = button.getModel().isArmed();
            if (isArmed != lastArmedState) {
                // The armed state changed. Do what you need to do here.
                System.out.println("isArmed = " + isArmed);
                lastArmedState = isArmed;
    }To use it, just do:
JButton button = ...
new ArmedStateListener().register(button);

How can I call my chart in Forms6i on When Button Press Trigger?

Hi Friends,
I have make a chart in Graphic Builder 6i and save on path C:\graph\test.ogd
Now I want to run this Chart from Form6i on When Button Press trigger.
I have call my report in forms using this command on When Button Press trigger.
Run_Product(reports,'C:\Cheema\Qdir_store\reports\pmms\sec_backlog',asynchronous,runtime,filesystem,TO_CHAR(NULL));
So tell me How can I call my chart in Forms6i?
Please reply me on urgent.
Thanks,
Shahzad

Just to recall after a long break of couple of years..... Pls check out if not wrong.
First of all you need to embeed the chart object on your layout window and make it visible = FALSE. This is a design time work. In the button press event, show the chart object by setting the visible property = TRUE.
Note, i could not paste u the sample code as i don't have forms installation on my PC. The above states is a logic you can apply.

Problem while hide a block on selection screen on button press

Hi,
I have added two buttons on the application toolbar of the selection screen. I have input fields under two blocks on the selection-screen. Initially the second block is hidden. If I press the button 1 the second block should be made visible.
For this to happen, I captured the button 1 click event using the following statement.
IF sscrfields-ucomm = 'FC01'.
Inside the if ... endif, I looped at the screen and made the second block visible. It was working fine.
loop at screen.
if screen-group4 = '013'.
     screen-invisible = 1.
     screen-active    = 0.
endif.
endloop.
Later the second button was added. Now when i run the report for the first time, if button 2 is clicked the hidden block appears on the selection screen even though i have not added any code for it.
Just to check, i commented the logic to display the hidden block on button 1 click event. Even without any code the first time i press any of the two buttons added on the application toolbar the hidden block is displayed.
I saved a variant for the report.
During execution of the report, if i select any variant then the hidden block is displayed.
Can anyone please tell me how to fix this problem.
Regards,
T2.

Disabled button fires events to event structure

Hi all,
I was trying to disable a Button on the frontpanel by using its enabled property while the event was executed. The ide wa not to create more events of this buttopn while its fucntion was executed. However thsi did not work.It was creating events even though it was greyed out.
I troied two different versions:
1) in the event case of the button (value changed) in a sequence I first dispalbned the button, execuded the code and then enabled it again
    Result: All events were generated even though the button was greyed out
2) in the event case of the button (value changed) in a sequence I disbaled the Button and then started a second event. The Second event executed the code and then enabled the Button egain
   Result: Even though the Button was greyed out events were generated
3) in the event case of the button (value changed) in a sequence I first dispalbned the button, execuded the code and in the timeout event I thenenabled it again
   Result: No additional events were generated
it seems that the enable state of the button is analysed at teh time when the event is execute din teh event case but not at the time when it was created?
So I Tried the Time Input of the case expecting that it woudl give me a time stamp of the time when the key was pressed - but instead it gave me the time point when teh event was executed...
Teh only othe rsolution was to set teh cursor to busy (however I dont want to see the changed cursor during the busy cycle)
So how can I make shure that no additional events are fired during the time teh code of the Button s executed?
Thanks for any help,
Rainer

to altenbach:
The evet takes about one or two seconds - I checked the behaviour as shown in the attached examples with LV 8.5, LV 2010, TV2011, LV2012 - allways exactly the same behaviour.
It does not make any difference weather you use switch when pressed or latched when pressed.
It does not make any difference weathe ror not you tag "Lock front panel" for that event
to sth:
> If you disable a front panel control (ie the button) you cannot click on it and a value changed event will not be
generated.
This is my experience so far as well, but if you disable and enable the control within the same event it does not work (see attaced example 1) and 2). It only works if you do the enable in the timeout event.
> The time stamp from the event case left hand property is the time of the event not the time of execution.
> If you ask for the timer value inside the event case it will be the time of event case executing.
In the attached exampel this is not the case. The time differecne between the Time input on the left and the Tick count
placed in the event is 0 for all events generated whil the button is supposed to be disabled.
As I wrote before, the explanation I have for this behaviour is that the events are generated by windows weather or not
the button is disabled and they are queued to the event cue. Only when the event is handeled LabVIEW tests weather
or not the button is disabled and ignores the event in case it is disabled. If the Disabling and enabling is done
withim the same event the button pressed events are added to thw event queue and the button is set to enabled before the next event (button pressed while it shoul be disabled) is handeled. When that event is handeled the button is enabled again (by the original event) and therefore the evenet is not ignored (because by the time of execution of the event the button is enabled again).
If the button is enabled in the timeout event instead of the button change value event all event in teh queue are executed before teh timeout event. At their time of execution therefore the button is steill disabled. Only then the timeout event enables the button again.
If the vi is set to busy (sand clock) this is activating actually a windows function/property and no events are queued to teh event queue by windwos. Therefore no button change event is added to teh queue.
Funtciomn of the 3 attached Vis (LV 2010):
Run the Vi, then press the Test button once - when it is greyed out click it a few more times. The test button value
changed event has a 2 second delay. You will see the event counter increase, and you will see the time difference
between the time property on the left of the event and the tick count vi whci is displayed in the waveform chart.
DisableButton 1: Disable and enable are ste in teh same event
DisableButton 2: The button is disabled then a second event is called to do the work and then enable teh button again
DisableButton 3: The Button is disabled in button change value event and it is enabled again in teh timeout event.

I want to execute selection screen by pressing enter button

Hi,
I have a requirement like after giveing values in selection screen I want to execute it by pressing enter button not by pressing execute button.
Please give some sample code if u have any solution.
Thanks & Regards
Venkatrami Reddy B

Hi,
You can achive this.
You just need to do all your coding under even AT SELECTION-SCREEN OUTPUT.
But you have to put a check also say counter.
Define a variable of type integer and then put the check on the mail block of code (whole program eccept selection screen) as mentioned below.
IF lv_count > 1.
program lines..
ENDIF.
lv_count = lv_count + 1.

Event should trigger when enter is pressed on select option for validation

Hi,
I want to trigger a event when enter is pressed on a select option field for validation.
I have created a select option through coding. I am not able to find out any method or class for that.
please advice.

Hi Sachin ,
If you want ot use the methods in the class CL_WDR_SELECT_OPTIONS.
You can find here:-
[WDR_SELECT_IPTIONS|https://cw.sdn.sap.com/cw/docs/DOC-20864.pdf]
Check these if can find ur required one.
If you are using any ui element then you can use ON_ENTER event as a action as stated by Baskaran.
Check also if these threads can help you:-
[WebDynpro ABAP select options method SET_VALUE_OF_PARAMETER_FIELD;

Pressing Enter Button Gives a Blank Page while Cursor is in Text Field

Hi,
I have a problem on my jsp page that there is a text filed (input type="text") and a button (input type="button") to submit the page.
When page loads the cursor blinks in the text field, and at the same moment if i hit the enter button of my keyboard it gives a blank page.
Here the button on page does not clicked by this enter button, no script calls neither the page submitted to the given url.
Kindly suggest what is going wrong.
Thanks in Advance
Rajiv K.

I'd come across this issue a while back: [http://tipsandtricks.nogoodatcoding.com/2007/07/html-single-text-field-submit-caveat.html]; when there is only a single text field in a form, then pressing enter causes a submit with the text-field as the initiator. The submit button isn't invoked. This means any onsubmit actions will not be called. A simple way out is to put in a dummy text field in the form and set it's display to none (using CSS/styling)
