How to go back to item that were just on in the tree if data block info has an error?

I have a tree that lists information about a Client (addresses, quotes, etc). When the user clicks on a node in the tree, a data block on the right gets populated with the information for that node. If the user enters invalid information for that node and then clicks on another node in the tree, the error appears, the data block keeps the information for the offending node, but the node in the tree that is selected is for the one the user just clicked on, not the offending node. How do I get the selected node in the tree to remain at the offending data block?

hi tina,
create a 'when-mouse-enter' trigger in the 'tree block'.. check the record displayed on the data block is correct.. if not disable the tree item.. so the user will not be able to select any other node without correcting it..
another alternative is to store the current node in a global variable.. check the validation in 'when-tree-node-selected' trigger.. if it fails then search for the treenode and position it back.. a l'il difficult
hope this will help u..

    If you mean backed up as part of an iPhone backup in iTunes?  If so, you would have to use 3rd party software to extract them from the backup, such as iPhone Backup Extractor.

  • I used to have a large music library on I Tunes but I somehow overwrote it with the few purchased items that were on my I-pod so I have lost everything apart from these few.  Can I retrieve a previous library even if I've somehow lost it?

    I used to have a large music library on I Tunes but I somehow overwrote it with the few purchased items that were on my I-pod so I have lost everything apart from these few.  Can I retrieve a previous library even if I've somehow lost it?  Any ideas?  I've tried the Apple Support but they just showed me how to retrieve previous purchases and don't seem to have any solutions to my problem.

  • How to restore points in apps that were erased by this god awful update?

    How to restore points in apps that were there before this god awful update?

    This wonderful update wouldn't effect any of this if you backed-up properly to iCloud or restored after the update. I didn't lose anything in my update.

  • Backed up photos that were deleted from iPad, where are they?

    Backed up photos that were deleted from iPad, where are they? Cannot find on pc or iTunes.

    X2 on King_Penguin's reply, however, those files are hidden by default.   I'm on Windows 7.  You'd click on your "Start", click on "Computer", click on "Organize" up on the top of the window and click on "Folders and Search Options".  Check off the "Show all Folders" under Navigation pane.  That will show all the hidden files.  Then you can follow the directions King wrote above.    Sorry, if you have a Mac, I don't know how to help you navigate to where the "Folders and Search Options" is.  Google should be a good resource.
    It's pretty simple once you find it.  I was moving my back up file from my lap top to my desk top because I wanted to begin syncing my ipad and iphone to my desk top.   Once I unhid the files, I copied it to a thumb drive, uploaded it to my desk top and voila.    Just make sure when you are done you check the box to hide the files again.  You don't want to leave them vulnerable.
    Hope this helps.

  • Phone died. How do I retrieve text messages that were on phone?

    Phone died.  How do I retrieve text messages that were on phone.

    Unfortunately, unless you had them backed up and stored elsewhere (like on the SD card or your computer), they most likely aren't retrievable.
    Are you sure the phone is completely dead?  Have you tried holding the power and volume down buttons simultaneously for 15-20 seconds to see if that will reboot the phone?

  • How do I back up documents that are stored in iCloud to my own hard drive?

    The trouble is, however I search for an answer to this question, I get instructions on how to back up stuff TO iCloud.
    I want to back up stuff that applications like Pages and Numbers are already storing IN iCloud.
    See, I don't want to have to trust iCloud to safely store my documents.  Not unless there are copies somewhere that I can fall back on if (it's really only a matter of when) something goes fatally haywire in iCloud.
    It's easy enough to do with a service like, say, Dropbox, which treats my "cloud-stored" files like they are in a folder on my hard-drive.  So when I run either a local (Time Machine/Capsule) or a cloud (Crashplan, in my case) backup, those files get backed up.  So I have at least three copies of those files - in Dropbox, on my Time Capsule, and on Crashplan's servers.
    So how do I do that with docs that are stored in iCloud?  Apple wants me to store stuff in iCloud - if I have iCloud enabled and want to save a doc to another destination, there are multiple steps I want to go through.  And I'm fine with using iCloud if I'm creating documents that I want to be able to access from my iOS devices as well.
    Yes, I can do that with Dropbox, but it's less seamless than doing it through iCloud.
    But I want my own backups of those files, and near as I can tell, Apple makes that nearly impossible because iCloud does not show up anywhere as a folder that I can access or sort.
    Or does it?  Am I missing something?
    If so, let me know.... if not... is there a solution to this dilemma, or is it just one more aspect of iCloud that Apple has not clearly thought through?
    Thanks,
    --PS

    Right.  You didn't read the post, you only read the title.
    The title came from an earlier step in the process when I was posing a question to the systen.
    The pertinent part of the question is "How to I back up documents that are stored in iCloud" 
    That the destination for the backup is NOT my internal HDD should be clear from the rest of the post.
    And frankly, even if that is where I want to back up to, that would at least give me two copies, at least giving me one duplicate of the stuff on iCloud.
    So please stop wasting my time if you can't answer the actual question: How do I backup content that is stored in iCloud.  The destination of the backup is irrelevant.

    I have two ipods in my house that were set up under the same email.  I have since assigned two different emails.  How can I change the game center account so that is not shared by both ipods because it is for two different users and they are not happy?

    By "game center account", do you mean Apple ID?
    If so, you can change it.
    1. Tap settings and navigate to iTunes and App Stores
    2. Tap "Apple ID" and then tap "Sign Out"
    3. Log in with a different ID.

  • How do I grey a bubble on a line item that I don't want the user to be able to input, but leave the others active in a form?

    How do I grey a bubble on a line item that I don't want the user to be able to input, but leave the others active in a form?

    I may be missing something here, but can't you just set the item to "Read Only" in the general preferences for that item?

  • "Read items that were created by the user" and inconsistent permissions

    Hi!
    I have enabled the option "Read items that were created by the user" and "Create items and edit items that were created by the user" in the advanced settings of a list. Indeed when a user creates an item in that list, that item is visible
    only by that account and other accounts cannot see it.
    However when the user opens the "Shared With" dialog he/she sees all users there, giving him/her the impression that the item is visible to everyone! Why is that? This is very confusing since this "Shared With" feature is the only way
    for a user to tell who can see an item.

    Let it make it more clear. User A creates Item 1. Users B creates Item 2. When User A sees the contents of the list he sees Item 1 only. When User B sees the contents of the list he sees Item 2 only. As expected.
    The problem is that if User A selects Item 1 and then clicks on 'Shared With' button on the ribbon, he will get pop up that indicates that the Item 1 is Shared with User B. Which is not true since User B cannot see the item. So User A wrongly assumes
    that Item 1 is Shared with User B!

  • How can I deactivate Adobe apps that were installed on a computer that is no longer available?

    How can I deactivate Adobe apps that were installed on a computer that is no longer available? I have a Creative Cloud membership, and I want to deactivate a device that is no longer available. I would have thought that there would be an option to deactivate all devices somewhere in My Account, but I can't find it.

    Hi acornies,
    There is no such option readily available under which you are able to deactivate the product on all the devices . As per the EULA , you are able to install the product on two machines only and once you try to have the product installed on a third machine that would provide you with an error message and an option to deactivate the products on all the previous installation .
    So , if the machine that you would be installing the product onto is going to be your third machine , you will be getting an error message that you have reached your activation limit and there would be a button to click on continue to deactivate all the prev installation .
    Please let me know if this works for you .

  • How do i retrieve deleted items that have been deleted by mistake

    how do i retrieve deleted items that have been deleted by mistake ?

    If they’re not in a backup, try using a data recovery product such as the ones listed here. Don't write anything else to the drive until the files are recovered or you choose not to recover them.
