Dropdown list populates 6 other drop down lists

Anonymous
Not applicable

Hi is there anyway I can populate 6 dropdown lists from another dropdown list? Can I use Global Binding if the 6 dropdown boxes are the same name?

This work on the first dropdown but not subsequent ones.

Hi,

You can't use global binding as that only works with the value of the drop down, not the actual list.  You can use a predicate binding, so if I had some xml like

<Languages>

  <currentLanguage>1</currentLanguage>

  <Language id="1" display="English"/>

  <Language id="2" display="French"/>

  <Language id="3" display="Maori"/>

  <Words>

    <Word language="1" id="1">one</Word>

    <Word language="1" id="2">two</Word>

    <Word language="1" id="3">three</Word>

    <Word language="1" id="4">four</Word>

    <Word language="2" id="1">un</Word>

    <Word language="2" id="2">deux</Word>

    <Word language="2" id="3">trois</Word>

    <Word language="2" id="4">quatre</Word>

    <Word language="3" id="1">tahi</Word>

    <Word language="3" id="2">rua</Word>

    <Word language="3" id="3">toru</Word>

    <Word language="3" id="4">whā</Word>

  </Words>

</Languages>

The first dropdowns list is bound to the Language element with $record.Language[*] and the value of the dropdown bound to $data.Languages.currentLanguage.value, the dependent dropdowns could be bound to the appropriate Word elements with $data.Languages.Words.Word.[language == $data.Languages.currentLanguage.value].

This way the only actual code you will need is a xfa.form.remerge() in the exit event of the language drop down.  Using remerge() will mean any form properties that have been updated by script will have to be re-applied.  This tends to be things like error highlighting or calculated values that are not bound to the data connection.

I have a sample of this approach here, https://workspaces.acrobat.com/?d=JEiwbw2GgRngqwL8umw8Og and some xml to preview it here https://workspaces.acrobat.com/?d=nXh795dIs8DLJ2erx5j1QA
