  my needs are I gave here.

  need 1: when I choose option amount that two text boxes does not have to be editable.when I select text tat box two percentage option will be editable.

  need 2: when I select the percentage in combox option and two text boxes are empty, and then click the button Save-> I want to display warning msg

  need 3: when I select the option amount combox and the two boxes are emptu click the button Save-> I don't want any warning messages.

  How to validate it and how to write backup for this function.

  any suggession or extract code is welcome.

  Thanks in advance,

  Looks like you are trying to do too much at once. Try to hang the events correctly

  The close event of the comboBox can do something like this

  protected function toggleTextEditing(event:DropDownEvent):void

  {

  If (this.optionCmb.selectedItem.label is "Percentage")

  {

  This.Text1.editable = true;

  This.Text2.editable = true;

  }

  Else if (this.optionCmb.selectedItem.label == "Number")

  {

  This.Text1.editable = false;

  This.Text2.editable = false;

  }

  }

  The button's click event can do something like

  protected function save(event:MouseEvent):void

  {

  If (this.optionCmb.selectedItem.label is "Percentage")

  {

  If (this.text1.text == "" & this.text2.text == "")

  {

  Alert.Show ("text is empty");

  return;

  }

  on the other

  {

  }

  }

  Else if (this.optionCmb.selectedItem.label == "Number")

  {

  }

  }

  If you can put in your entire code, maybe I can have a look to see if I can find something wrong with that.

• How can I update by program table combo box control type def?

  I use LV 8.6.1 and I am trying to create a table control panel object in which the user can select an item to list box for each element of the array.  I also have to periodically update the list of values.  Currently, I have configured the drop-down list box (selection of Automation sequence - see attached) as a type non-stricte def so I can write news channels to the list values when I need to.  But I can't seem to find a way to get the table (list of batches - see rasthaus) fill the new value drop-down list box.

  Automation box refelcts the new string sequence selection that I add programmatically, but the combo boxes in the batch list table control do not have the new channel.

  Anyone have any ideas?

  I have attached the screenshot of the drop-down list and table controls.

  Thank you

  I considered that mention strings and values have a property that cannot be stored in a typedef, but when I tried it out, it seemed that it was.  So I just did not comment on that.  Maybe the strings and values may be among the typedef, maybe not.  The values of the controls certainly cannot.  Strings and values can be in kind of a gray area.  But you can certainly expect changes to a control to automatically update another control, because they are typedefs.  You cannot change the typedefs during execution.

  Let's put another example that has nothing to do with the values.  You have a regular typedef of a digital.  It is saved with the text in red in scientific notation.  You place two instances of this on your drawing.  You can programmatically change each other colors or other digital formats.  A change does not affect the other.  If it's a strict typedef, you would be locked in the way in which it was saved and could not change it programmatically.

  Take a look at this.  If you cannot programmatically, to update your channel list and values for a single combobox (a scalar string) you will be able to put up-to-date for when the combobox control is the data type for a table.  Simply get a reference to the element of the array.  It does not use typedefs anyway.

• Channels not defined in Combo Box Bug?

  I found a problem with the drop-down list box control:

  1. create a drop-down list box and deselect 'allow Undefined Strings.

  2. run the VI

  3. Select a list box item

  4. press on the BACKSPACE key to remove a few letters of the item

  5. click on on the front panel

  The combo box is filled with a string not set!

  Disabling the BACKSPACE key is not a valid work-around because the user may need this while typing the value.  Expected behavior of the control would be to restore the previous value.  Any comments?

  Yes.

  Take a look at the bug report in this thread.

• Combo box multiple values

  Hello world

  I would like to use a drop-down list box to send two different values for two entries for every combo box selection. For example if I select "Channel 1" form the drop-down list box, then the integer "1" and the string "1 x", which I can then send to the two separate terminals.

  I really have no idea how to do that, my one thought was to combine into a single value for the value of drop-down list box and then to cut the string and use it that way - but this seems awkward.

  See you soon!

  Instead of a combobox control, I'd probably use a ring.

  

• How can I do a multiple selection in Enum control or control of the ring or control Combo box

  How can I do a multiple selection in Enum control or control of the ring or control Combo box

  You can not.

  You can use a listbox control.

  An alternative solution is to write the code and each selection, the user gives an enum, for example, can be send to a table and invite the user to continue to select...

• Selected pass contains a string indicator combo box when you press the Enter key

  Hello

  How to pass selected contains a string indicator combo box when you press the enter keyboard key?

  Right now I use a button to send the command selected in the combox to string indicator.

  The photos shows a combo box with the button that I use to send to the indicator as example.

  After the user selects the text to pass, "send the cmd" button must be pressed to pass the string.

  I need to pass the selected string when the user press enter on the keyboard rather than press the button 'send cmd '.

  Kindly to you needing help.

  Hello

  You can use a structure of the event to capture keystrokes and filter, transmit only the drop-down list box "value of the indicator of channel when you press the return or enter key."

  Let me know it the joint allows an example (in LV 8.6).

• combo box record strings at run time

  Anyone know if there is an easy way to save new channels in a drop-down list at run time?

I found the 'Ring and Combo Box.vi' example that will do the work, but that seems a little exaggerated to me - there at - it a simpler way or a better control should I use? Thank you very much.

• Additional mouse click required to set other combo box values based on the current selection combo box

  I have an Acrobat PDF form where there are 8 combo boxes (not editable) which are related in a logical way, but have unique names and a list of unique values, with the exception of a default value that represents 'null' or 'none '.

  for example:

  The first 1 combo box value is "none" followed by the value A1, B1, C1, etc., and Combo box 2 the first value is 'none' followed of the values A2, B2, C2, etc...

  The combined list useful values for every combo boxes relate to the types of unique product for the user to select mode 'radio button '.

  When the user selects one of the 8 Combo boxes and performs one selection other than 'none', then the form must verify the 7 other combo boxes and when any current value is not equal to 'none', he has to change 'None '.

  The following script is currently enrolled in the properties of "Actions - Mouse Run - Up a Javascript" from one of the drop-down list boxes, others have similar scripts as well.

  (var cbox is the current combo box and var obox is for other drop-down list boxes when called).

  Cbox var = this.getField ("TagStyleStake");

  If (cbox.value! = "none")

  {

  obox var = this.getField ("TagStyleBasket");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStylePushon");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStyleHandle");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStyleHang");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStyleBlank");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStyleMolded");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  Obox = this.getField("TagStyleSignage");

  If (obox.value! = "none")

  {obox.value = 'none' ;}

  }

  The current problem is that, when a Combo is selected and one option other than the 'none' value is clicked, the other combo boxes do not include the 'None' value.

  To reset the other combo boxes requires another click on the option which has just been moved to the position selected in the drop-down list, but it seems reasonable that the drop-down list boxes should reset with the initial click the option in the drop-down list.

  I tried other properties (Format, validate, Calculate) but without success.

  What I'm missing here?

  The normal way to proceed is to define "value option selected to validate immediately" and to place the code in the event of the combo box button. And instead of the first two lines you have, you need to use something like:

  If (! event.willCommit & event.changeEx! == 'none') {}

  Your other code goes here

  }

  The changeEx property returns the value of exports, if any, for the selected item.

• With a small twist combo box?

  Hello world

  Uh, I want to do some filing or boxes of combo boxes where if the user choose an option in the next drop-down list boxes this option will not appear. Can I do this?
  How?

  Thanks for the help, sorry if this question has been asked and especially sorry for terrible English.
  
  Bence

  OK, I see now.

  So let's say that the first box is called Combo1 and the second Combo2. You can add this code in the validate the Combo1 event:

  var items = [];

  for (var i = 0; i)

  If (event.value! = event.target.getItemAt (i, false))

  Items.push (Event.Target.getItemAt (i, false));

  }

  getField("Combo2").setItems (items);

• Combo Box Manipulation of external file

  I looked and looked and looked at can not find much info on it. And I do not get the case. My ultimate goal was to load values from a text file called "data.txt" which would be stored with the pdf form. But I can not even understand how to fill the combo box list via code. Can someone help me or tell me if it is possible to load the values from a text file?

• Hide / remove / bypass solution the arrow in the combo box

  Here's a thing. I need to eradicate the combo box arrow. We produce a feedback form with multiple options for your comments, once the guardian chose the relevant feedback they want the arrow to not be visible to the student. Essentially so that the viewer of the end of the PDF can not say there is a combo box with the arrow, see arrow. Looking around I found that you can not hide the arrow to the right of the combo box.

  A possible solution is to design a black bar in the form that may hide the black arrows (unless they become white). However, I prefer the code solutions more own which are not dependent on a static Visual design. I wonder is there away to hide the drop-down list together box and passing of the list item selected in a text field?

  FYI a list box is not suitable that the color blue/gray selection is then visible.

  Charlie

  When you create a read-only combo box, the arrow is not displayed. This is probably what you want to do anyway before distributing the documents to the end user. You can automate the process of creating fields read-only. Here's a script how it for a single field:

  getField("combo1").readonly = true;
  

  An option even better perhaps to flatten pages, which converts the apparitions of field content page regularly. The arrow does not appear for the drop-down list boxes, and it no longer fields of interactive form for the end user to mess with. You can use the following JavaScript code to do this:

  flattenPages();
  

  or use optimization PDF or preflight to do the same. Or use this nifty script: http://www.uvsar.com/projects/acrobat/flattener/
