Prompt to save the chages when leaving the page

Hi all,
I have the following scenario:
I have a plsql region with 15 records pro page with text fields and checkboxes.
When the user does update any field and navigate to other page (or clicks to other pagination page) without click on the button "SAVE" or "CANCEL" I would like to show him the confirm dialog "The changes was not saved. Save it?" or anything like this.
Is it possible?
Thanks

  • LabVIEW prompts to save the vi when closing the reference

    In our application, we - Open vi reference - finding its execution state - closing the vi reference. While closing, LV prompts to save the vi, how to avoid it. I can see option to enable LV prompt, but no option to skip it. We use 0x20 for now to avoid the loading dialog.
    We appreciate your input
    Thanks

    Solved!
    Go to Solution.

    I have seen this in the past with scripting VIs and I tried to resolve it but couldn't.  So my solution was just to supress the dialog temporarily.  Darren posted over on LAVA a VI that does this.

  • How do I tell Adobe reader to open a file instead of being prompted to save the file?

    how do I tell Adobe reader to open a file instead of being prompted to save the file?

    Go to Tools - Options - Applications and enter "pdf" into the filter field. Select the action that you want to associate with PDF files.
    In your case select one of the "Use Adobe Acrobat" actions.

  • Display a warning when leaving a page

    Hi,
    I have created multiple APEX pages and would like to create a warning when leaving a page  when changes are made to the page.  Iam new to APEX and javascripts. We are using Oracle APEX 4.1,  connecting to a 11 g database  and Internet Explorer 8.0.  I have seen postings from older versions of APEX and have attempted to use the logic and receive multiple screen prompts. I appreciate your assistance with this challenge.

  • When I open a saved document in pages, then close it right away without making any changes, why does it ask if I would like to save the page or all new info will be lost?

    I have a few saved documents and when I open them to view them quick, sometimes when I close it, I will get asked if I would like to save the document or all my new info will be lost. I didnt change anything so Im not sure why it asks me that. When I open the document again, all the info is there and nothing is different. Thanks

    Unless they were Word documents, Pages has done nothing really, but it is updating date information in the file.
    It is annoying but just ignore it and don't save.

  • Panorama never saves the pages after the browser is closed. Will there be such feature in the future? And another thing, i cant never submit a feedback through the browser, because it tells me im not running the latest beta build when im using 4.12pre.

    Windows 7, Minefield 4.0b12pre (updated 2011-02-09)

    Well, with 4.0 beta there is the option of restoring a previous session on demand (thumbs up for that :P) AND what's even nicer it even saves the state of Panorama.
    Just tried it and if you have tab groups defined in Panorama when you close Firefox, if you choose to restore the session when you restart the next time (either by using the Restore button on Firefox's default homepage or the option in the History menu) Panorama gets restored as well.

  • Always prompted with Save As Dialog when viewing dashboard

    Hi,
      We are having problem viewing dashboard which contains Xcelsius document. In our development server we were able to view all dashboards with embedded Xcelsius document but when we move it to our production server it shows different output. Everytime we try to view the dashboard it keeps on prompting a "Save As Dialog" instead of showing the Xcelcius file. I really have no idea on what to do next, please help.

  • Save the page in server side

    Hi all,
    I have some iViews in my page. That iViews are draggable like as in iGoogle. Now what i want is if i change the position of the iView , after refreshing the iView should be in the same position(what i have changed) . The page should be save in cookies or server side like igoogle.
    The URL of the iGoogle
    [iGoogle|http://www.google.com/ig]
    How can i achieve this using script?
    Help me in this regard.
    Thanks & Regards,
    Hemalatha

    Hi,
    When ever an Iview is dropped to a new position, you will have to reflect this position change in pcd.
    An idea would be to use AJAX and call a portal service where logic is implemented to change Iview position in pcd. You can implement this in personalized context of user, so that the change is made only for current user.
    PCDAPI Remove iView from Page

  • My Google Bookmarks says that my browser is offline and won't let me save the page but the Firefox booksmarks will let me save it.

    My Firefox bookmarks will let me save the web page but Google bookmarks won't and tells me that my browser is offline and to check my browser and network settings. I also can't download you-tube videos like I used to. When I hover on the picture, the "download" box does not show up but it does give me the option to stop download. I just changed to Shaw internet.

    Did anything happen to the computer?  It appears that you are trying to sync to another iTunes library since in that case you can only sync with one iTunes library.

  • Run a process when leaving a page

    Hello,
    Is it possible to run a process when users leave a page?
    Let me explain:
    On a page, I have an Automatic Row Processing (DML) and a PL/SQL process. These two process are run when users click on the "Apply change" button.
    Is it possible to run these two processes ALSO when users leave the page (click on another tab) ?
    I want to do this to make sure that the changes are saved, even if users forget to click the "Apply Changes" button.
    Thank you in advance for your help.

    Have you looked into using a pl/sql dynamic action page unload event?  I haven't tried before but if you set the item values in the first step of the dynamic action and then execute a pl sql routine that mimics the DML it may work.  Since the action would fire after every page unload, it would also probably need some validation to ensure it does fire during normal processing.

  • EPCM error when leave Webdynpro page ???

    In Portal, when navigate from page with webdynpro iViews to any other workset or page, clicking in some node of the top level navigation, opening a windows alert popup , and said: Exception in EventDistribute occurred. Throw it to upper level?
    And then click accept 4 times let me continue.
    After trying multiple alternatives, the issue certainly is occurring when:  I am in a page with at least one webdynpro java, and I go to another. That is, to leave or close the webdynpro iView has generated  the problem.
    When I choose "debug" the exception with MS Dev studio, I found this error code, this is the point when the exception raise:
    EPCM.eventDistribute=function( consumers, eventObject, resultArray){
    var isRetValCollect=(resultArray != null);
    var eListener
    var retVal;
    for (var idx in consumers){
    eListener=consumers[idx];
    retVal=null;
    try{
    retVal=eListener.call( eventObject );}
    catch( e){
    if (EPCM._private.dbgException){
    if(confirm("Exception in EventDistribute occured.\nThrow it to upper level ?")) throw(e);}
    if(isRetValCollect && retVal != null){
    resultArray[resultArray.length++]=retVal;}
    any suggestion ?????
    thanks in advance!
    Leandro.

    Add this: not only when leave a webdynpro iview or page is the problem, also when resizing a webdynpro page in the IE.
    Any change in the screen size, raise this popup error
    any idea???
    thanks in advance

  • Hi everyone. I am getting the Invalid signature message when installing Itunes and when I try and download directly from apples page I'm prompted to save the EXE.setup file and then nothing happens, it goes straight to the "thanks for downloading itunes"

    Hi all, as Ive said in the question, anyone help me with this, have tried most of the suggestions Ive found so far.
    Stephen

    No, Nothing happened, nothing was downloaded. When I say nothing happened I mean NOTHING HAPPENED, What can I say to make it more clear. How could I run a file that wasn't downloaded.....Nothing happened, rien, nada, b***** all. Why would I post a message saying "When I press the Save button nothing happens" if something had been downloaded.
    I've found out why. It is because I am using Firefox. Presumably a case of Apple treating us users of the superior Operating system (Windows) with distain.

  • URGENT! Alive PDF - export PDF file ("my computer" prompt to save the file, not create in browser)

    Hi - I'm having issues with my code and I'm not an ActionScript coder by any means. I'm using Flash Builder 4. I've been able to figure out how to export to PNG and to XLS but PDF is really killing me.
    Below is my code and it's not causing errors when I do the release build but the my button doesn't work to export to PDF.  I'm trying to create a PNG using the PNGEncoder and then push that out to PDF (when the PDF button is selected). I used some sample code and I've commented out parts that I didn't want to use or didn't seem to apply to my application. Unfortunately, I have a deadline of May 3rd on this and there is no one else in the office here to help me... hope someone out there can.
