Combo Box Types. Here, users can either make a predetermined choice, or input their own information into a form.
As a result, it requires complex programming to make use of that input. Programmers and developers have to treat the user-submitted input differently than the drop-down list input. For example, a user in a form might choose from three predetermined elements: red, blue or yellow.
Or, they might enter something like "purple. This is the challenge of interpreting input from a combination box control. Some IT pros may use the terms "combination box" and "drop-down list box" interchangeably. Here, it might be helpful to utilize a term like "non-editable drop-down box" to describe a purely drop-down list box that is not a combination box and does not have that user-submitted input functionality.

If it finds a match, runtime sets it as the currently-selected item in the cell. Otherwise, it ignores the item and sets the cell to the -- Select One -- value.
If the target cell resides in a grid column that does not have a data dictionary item with an associated UDC, then runtime creates an embedded combo box with one item set as selected having a Key parameter of blank and an Item description parameter of Uninitialized. Then runtime disables the cell. This chapter discusses the system functions unique to the combo box control when it resides on a form that is, it is not embedded in a grid.
Use this system function to add an item to the combo box if it is not displaying a list that is based on a UDC. Input, required. The key of the item to add string or math-numeric.
The name of the item to add string. Input, optional. The zero-based index position where the item is to be added integer. If you do not specify this parameter, runtime appends the item to the bottom of the list. The default -- Select One -- prompt always occupies index position zero.
If an invalid index is specified, the addition of the new item fails and an error message is logged. Use this system function to add an item to the combo box.
Runtime verifies that the Key and Item parameter values are both specified. If either is missing, the addition of the new item fails and an error is logged. If you try to insert an item having a key value that already exists in the list, runtime will not add the item and will log an error. The combo box control must reside on the form as opposed to being embedded in a grid.
The control must have a valid data dictionary item associated with it. Runtime recognizes the fact that it currently does not exist in the control's item list and that it is a valid key value in the UDC's set. Otherwise, the attempt to add the new item will fail.
Use this system function to get the displayed description of the current selected item of a specified combo box. The object to which to assign the return value that designates the description text of the current selected item string. Set the parameter to an applicable object from the object list. Use this system function to get the zero-based index position of an item in a combo box list by specifying its key. If the key value specified does not exist in the combo box's current set of items, no index value is returned and an error message is logged.
The key of the target item string or math-numeric. The object to which to assign the return value that designates the zero-based index position of the target item integer. This system function returns the zero-based index position of a combo box item to the object identified by Index. Use this system function to get the displayed description of an item in a combo box list by specifying its index position in the list.
If the index value specified is invalid, no description is returned and an error message is logged. The zero-based index position of the target item integer. The object to which to assign the return value that designates the displayed description text of the target item string.
This system function returns the name of a combo box item to the object defined by Item Description. Use this system function to determine the total number of items in the combo box list including the -- Select One -- prompt. The object to which to assign the return value that designates the number of list items. This system function returns the number of items in the combo box list to the object identified by Number.
Use this system function to get the key of an item in a combo box list by specifying its index position in the list. If the specified index value is invalid, no key value is returned and an error message is logged. The object to which to assign the return value that designates the key of the target item string or math-numeric. The name of the prepopulated JD Edwards EnterpriseOne cache from which to load combo box items string.
The name of the predefined JD Edwards EnterpriseOne data structure to use to load the combo box items from cache string. This must be the same data structure as the one used to initialize and load the cache. The cache column containing the key values for the items to be loaded into the combo box type defined by data structure. Set the parameter to an applicable object from the object list the list is empty until you select a data structure.
The cache column containing the text descriptions for the items to be loaded into the combo box type defined by data structure. The cache column containing the values against which to filter items to be loaded into the combo box type defined by data structure. The data type must match that of the Key Column parameter.
A value used by runtime to compare against values specified in the Filter Column parameter string or numeric. The data type must match that of the Filter Column parameter itself. Otherwise the retrieved record is ignored and runtime proceeds to process the next retrieved record. The Load From Cache mechanism always retrieves all of the records currently loaded in the cache from the enterprise server to the Web server when the call is made regardless of whether the optional Filter Column and Filter Value parameters are specified.
If you include several combo boxes on a form, you might decide to create a single data structure that loads the cache for all of them.
However, you must use discretion in balancing how many records are loaded simultaneously in the cache versus the performance penalties that might result when loading a single combo box with a relatively small subset of the cache. Use this system function to remove an item from a combo box list by specifying its index position. The zero-based index position of the item to remove integer. A special value indicating whether to remove all items. You can also clear all items from the list.
The key of the item to remove string or math-numeric. A flag indicating whether to remove all items. Use this system function to set one of the items in the combo box as the currently selected item programmatically.
The item's description appears in the control just as if the user had chosen it. The key of the item to set string or numeric. This section discusses the system functions unique to the combo box control when it is embedded in a grid.
Use this system function to add an item to the combo box list embedded in a grid that is not displaying a list based on a UDC. The grid column to affect. The grid row to affect integer.
