• Have the drop-down list boxes become visible depending on the selection in a previous drop-down list box?

  Hi, im doing a form that only shows some options based on the previous selections.

  So far I have buttons which allow a user to select a specific product, and then by using the drop-down combo boxes select some optional features.

  I then have a simple javascript code that bears the name of a product at a price (i.e. the user selects product 'A', the review sections shows priced at $ 99).

  My problem is with additional customization options that depend on previous choices.

  Is it possible to have some drop-down list boxes become visible depending on the selection in a previous drop-down list box? If yes how could I impliment it?

  Currently my best idea is to have a button that could ask the user if he or she had previously chosen a certain selection and then reveal areas of correct drop-down list accordingly.

  Thank you

  Hello

  With a small change I think that the code works as expected. I changed your mainDD.value to event.value, as on the validate event the mainDD.value property cannot be updated as expected.

  script

  this.getField("Dropdown2").display = display.hidden;

  this.getField("Dropdown3").display = display.hidden;

  this.getField("Dropdown4").display = display.hidden;

  Switch (event.value)

  {

  case "a":

  this.getField("Dropdown2").display = display.visible;

  break;

  case "b":

  this.getField("Dropdown3").display = display.visible;

  break;

  case 'c ':

  this.getField("Dropdown4").display = display.visible;

  break;

  by default:

  break;

  }

  end of script

  Hope this helps

• In the drop-down list of fonts, I clicked on the search option, and all my fonts disappeared. How can I disable this feature so that my fonts again?

  I explore my office of the newest version of Adobe InDesign. On the drop-down list of fonts, I clicked on the search item and all my fonts disappeared. How can I turn this option off and get my fonts to appear again?  See below.

  

  The departure is for your Favorites. If you have any favorite added, the list will be empty.

  The other symbol is for Typekit fonts. If you have not used the fonts in TK, the list is empty.

  Click the TypeKit... looks like he was depressed (clicked on).

  Drop-down lists will not open now - for example, Twitter login drop-down list (so cannot connect to Twitter). Drop-down lists has worked for all the previous versions of Firefox.

• I have a drop down list with categories, how to close the categories?

  Hello

  I created the drop-down list categories and in each line, I'll choose a category in the menu dropdown.  How to add each category?

  It's the number 3.6.1 (2566), El Capitan

  That is to say.

  gas

  meal

  Rental

  I want to make the sum of all the lines that are "gas"?

  Use a drop-down menu the right way to do it?

  Thank you

  Edwin

  Hi Edwin,.

  Take a look at the personal Budget template in the template chooser > personal finance.

  SUMIF formulas are in the Budget sheet > summary by the table of categories > column C.

  The drop-down Menus (called context Menus in numbers) are in the leaf of Transactions > column C.

  Make sure spelling is accurate, or numbers will not find a match.

  Please call with questions.

  Kind regards

• Empty drop down list - planning - Web Forms - Dimensions in the axis of the Page

  Hello

  The drop-down menu that appears when you click on one of the dimension in the axis of the web forms page appears empty. The problem is unique to the single dimension when used with Alias Web form that a single application a plan type and a single instance. The special dimension has more than 1,500 members of level zero and has a seven-digit code and description of words 2 to 5 in the alias.

  I tried to rebuild the shape / LCM for instance different but nothing has worked. I think that this could be attributed to the problem in the JavaScript for menu drop-down. But I have no knowledge on javascripts so abstained.

  Feel free to ask all the questions and thanks in advance.

  Thank you

  RJ

  Finally with the help of the Oracle, I found the problem. The problem was some control characters in the names of aliases which are not visible in the user interface. Somehow these characters in the name of the alias has been added during the transfer files on the remote server or the load control metadata.

  changed ODI reloaded code execution on the target data store, metadata, and the problem is solved.

  See you soon.

• I have a drop down list with numbers refrence and show the hidden sub

  I have a form that has a drop down menu that has several numbers 1,2,3,4,5,6. I also have a subform hidden with the information that I need to post, so if they want 2 I need 2 instances of this subform to show. If they choose 3 I need 3 instances of this subform to apear. ECT... I have all text flowed and the West.

  Ok. In this case you must first define the instance of the subform, and then you will need to loop through all instances and make these visible subforms.

  In the change event of the DropDownList control, you can put the following script.

  var a = xfa.event.newText; This will capture the value in the case of change, if you want the script to the event exit you have

  AreadDoorMF.instanceManager.setInstances (a);       to make it in the var a this.rawValue

  for (var i = 0; i)

  {

  xfa.resolveNode ("AreaDoorDF [" + i + "]"). DF.presence = "visible";

  xfa.resolveNode ("AreaDoorDF [" + i + "]"). DF. Header.Presence = "visible";

  }

  Sorry I just setInstance instead of setInstances

  Thank you

  Sameh salvation,

  Thanks for the reply. Your code

  1. DCIteratorBinding iter is BindingContext.getCurrent () .getCurrentBindingsEntry () .get ("iteratorNameInPageDef") (DCIteratorBinding);.
  2. Object secondDropdownValue = iter.getCurrentRow () .getAttribute ("AttributeName");  has been really helpful to get the selected value.

  Thank you very much.

• Connecting 2 fields drop-down list and have some appear field

  I've read about the binding of the two drop-down lists when you select something in the first box and then it adjusts the options in the second drop-down list box.  I love those who can use in the future.  I have a question a little.

  Can I have two lists that both selections control what fields appear below drop-down list?  For the examples list 1 to A, B and C list 2 has red, Orange and yellow.  I'll choose different combinations of the two and have different things to be displayed.  At Red and has fields 1, 2 and 3 show.  B and yellow display 1 and 3 and so on.

  Is this even possible or do I need to create different combinations all in one field and script the different responses that, I think I know how to do?

  Thank you!

  Hello

  The problem is that you are hiding the subform, BUT you try to assign to the presence of individual boxes in the subform visible. It won't work, because the subform itself is set to hidden.

  Look at the boxes to check and see if you can group them in series that are always hidden or visible. Then script against subforms and NOT the boxes. If you can not group the boxes then you will just have to refer to them individually.

  The textfield object was just a typo.

• dynamically load the Options in a drop-down list in C++

  Hey guys,.

  I'm trying to dynamically load items Option in a drop-down list by using C++.  I have a function in my class of WorkManager file that does the trick:

  QStringList WorkManager::getListOfItems() {
      int i = 0;
      QStringList taskNames;  // used for debugging mainly, so i can print the list out to debug
      QList  myObjects = m_model->toListOfObjects();
      DropDown * dpList = bb::cascades::Application::instance()->scene()->findChild("scriptListDropDown");
      if (dpList != 0 ) {
          dpList->setSelectedOption(0);
          dpList->removeAll();
          for (i = 0; i < myObjects.size(); i++) {
              Task * myTask = (Task *) myObjects[i];
              taskNames.append(myTask->taskName());
              dpList->add(Option::create().text(myTask->taskName()).value(myTask->command()));
  //          delete myTask;  // do I need to delete the task object?
          }
  //      qDebug() << "WorkManager::getLIstOfItems(), ---> list of tasks is : " << taskNames;
          return taskNames;
      } else  {
          qDebug() << "WorkManager::getListOfItems(), ---> dpList was 0";
          return taskNames;  // empty list
      }
  }
  

  I also found this thread:http://supportforums.blackberry.com/t5/Native-Development/Adding-options-to-a-DropDown-from-c/m-p/21... that helped me get the filled drop-down list when the application starts.

  However, I need to re - fill list from time to time, when the list (a GroupDataModel) changes.  calling the function above a second time anywhere in my application appears to hang the application immediately.

  I think / thought it might have something to do with the slot for the onSelectedValueChanged, but I can't understand it.

  It seems down right when I do dpList-> removeAll().

  I also can't seem to find the right place to call this function to an object of type in my class.  I think it's because the drop-down list is not ready yet as the dpList * is always 0 unless what I call after the line:

  app->setScene(root);
  

  in the applicationui.cpp file.  Calling it works on start-up, but trying to update the list later (by removeAll() and recreate) causes the app crashing.

  is there a better way to do it?  .. and make it safer?  I can't understand how to do this.

  Thank you!

  First, drop the:

  dpList->setSelectedOption(0);
  

  Not only if it is not necessary, but it will explode your application if the function is called when there is already no options in the menu dropdown.

  Also, do NOT delete the task, because it is still owned by the datamodel. I also see that you use type casting C, which just blindly accepts your cast, even if it's a mistake. Instead, if you know for sure what kind it will be this way instead:

  Task* myTask = static_cast(myObjects[i]);
  

  If you are not sure if the type you are casting the is the type you need, use the dynamic_cast instead:

  Task* myTask = dynamic_cast(myObjects[i]);
  

  The advantage of this more static_cast , is that if you try to perform a type cast is not compatible, then myTask will be set to NULL.

  Alternatively, Qt offers a replacement for dynamic_cast which works on platforms where is not regular C++ casts.

  Task* myTask = qobject_cast(myObjects[i]);
  

  It is functionally equivalent to dynamic_cast, but as I said, it works on all platforms that Qt exists, whereas dynamic_cast cannot.

  Once you did get back to us.

• Selecting correct state in the drop-down list.

  Here is my delima. I have a form that gets repopulate when users come back to update their contact information. Name, address, etc. of the State. What I am having a problem with performs their State to be selected from a drop-down list. For example, if I'm from Ohio, so I want Ohio selected in the drop-down list. I don't want the user to have to select again the State if the information has not changed. Here's an example of how it is formatted.
  
  < select tabIndex = "5" name = "State" >
  < option value = "" selected = "selected" > < / option > "
  < option value = 'AL' > Alabama < / option >
  < option value = "AK" > Alaska < / option >
  < option value = "AZ" > Arizona < / option >
  < option value = "AR" > Arkansas < / option >
  < option value = "CA" > California < / option >
  < option value = "CO" > Colorado < / option >
  
  Of course, the two-letter abbreviation is written and retrieved from the database.
  Everyone works with this before?
  Any help/information is appreciated.
  Brian

  Here's how I made this...

  Top of the page put

  Then, when comes the time to put the list do that...

  some>
  some> Alabama
  some> Alaska
  etc...

  I hope this helps.
