I have a XamDataGrid with XamComboEditor as its CellValuePresenter.
I have written a handler for XamComboEditor SelectionChanged event (XamComboSelectionChanged) that updates my collection as per selected item.
When I apply filter to the XamDataGrid from its header, it triggers XamComboSelectionChanged event handler somehow and the value from XamDataGrid.ActiveRecord gets updated due this event handler. I want to avoid this.
This problem does not occur if I don't click on any record. i.e. XamDataGrid.ActiveRecord is null.
If there is any way I can unselect the selected row my problem would be solved.
I have tried setting XamDataGrid.ActiveRecord = null in RecordFilterChanged event of XamDataGrid didn't work.
XamDataGrid.ActiveRecord.IsActive = false didn't work.
XamDataGrid.ActiveRecord.IsSelected = fals didn't work.
Also I tried to update dependency property but I can only set it to any other record only which still causes same issue:
xamDataGrid.SetValue(XamDataGrid.ActiveRecordProperty, xamDataGrid.Records[0]); -- can't set anything out of index here.
Please help
Thanks
I want to create a dynamic action, that will set a value to an item on the page, when the value of another item (autocomplete text field) is set.
So the proccess goes like this:
Click on the autocomplete field
type some letters
choose one of the suggested values
I cannot find an event that will be executed when the selection of one of the suggested values happens. This way, I cannot see how I can read the value of the autocomplete field, once a suggested value is selected.
The change event doesn't fit my needs, it doesn't execute when one suggested value is selected.
I had the same problem, found this link: https://community.oracle.com/thread/2130716?tstart=0 and modified my dynamic action as follows to get the desired behaviour:
Event = Custom
Custom Event = result
From the link:
the problem seems to be the default behavior of the browser. When you
enter some text into the autocomplete and the list is displayed, the
focus is still in the text field. Also if you use the keyboard cursors
to pick an entry the focus will still be in the textfield. That's why
the change event of the textfield doesn't fire. It only fires if you
leave the field.
On the other side if you pick an entry with the mouse, the browser
will remove the focus from the text field for a moment (before the
JavaScript code puts the focus back), because you clicked outside of
the field. But that's enough so that the browser fires the change
event.
I had a look into documentation of the underlaying jQuery Autocomplete
widget
(http://bassistance.de/jquery-plugins/jquery-plugin-autocomplete/) and
there is actually an event called "result" which can be captures if an
entry is selected from the drop down list.
Try "Lose Focus" as event. It will trigger your dynamic action when you leave the autocomplete field, i.e. your curosr is moved to another field.
This probably depends on the APEX version you are using.
In case of 18.2, because the underlying component is based on Oracle JET's "inputSearch" component, you need to use following configure to capture the select change event for text with autocomplete:
event: Custom
custom event: ojupdate
Reference:
https://docs.oracle.com/cd/E87657_01/jet/reference-jet/oj.ojInputSearch.html#event:optionChange
I turned on the browser console, then turned ApEx Developer toolbar debug, and found that, on the contrary, the "Change" event does fire upon user clicking with the mouse on one of the selections. However if the user uses keyboard (type a few letters to narrow the list down, then use down arrow key to arrive at desired value, then press enter) then the Change event does not fire, just as you say.
Moreover: even when you do get the value sent back via mouse-click initiated Change event, the value isn't the autocomplete's complete and valid value, but instead the possibly partial and wrong-case value just as typed by the user. I.e., the the change event's submission of the value precedes the autocomplete's substitution.
The answer that #VincentDeelen gave is the best alternative that I can see, although it doesn't quite give that "instantantenous synchronicity" feel. You could maybe use the "Key Down" event, but be careful with that. You could get a really excessive amount of web and db traffic as each and every keystroke (including corrections) results in another firing of the dynamic action.
Testing environment: ApEx 4.2.3 with Chrome 33 as well as IE 9.
p.s. This might be worth a mention to the ApEx development team as well.
It's not really ideal, but you could use onfocus(). I'm looking for the same thing you are, I think, a custom event that fires when the selection of a suggested value happens. I haven't found it yet though and that is my work-around for now. It will run whatever function you've created for this initially with no value, but once the selection is made it will return focus and run the function again with the right value. Like I said, not ideal but it works.
Jeffrey Kemp is right. You can set it up through a dynamic action using the custom event, result. You can also register it on page load using document.getElementById("{id}").addEventListener("result", {function}); or $("#{id}").result( function( event, data, formatted ) { //something here });.
Oracle apex 19 now added a "component event" when you create a dynamic action called "Update [Text Field with autocomplete]" - this action is fired when you select a value from the list, but not when you leave the field (similar to adding the custom event "ojupdate").
I have used webshims for html5 form validation in a single page app with multiple pagelets(divs). The forms are not submitted but local javascript is invoked after each conversation and collected data is posted .
Next I iterate over all the fields and reset the values.
Then I take the new user back to the first pagelet having first form for the new conversation. This time even after filling the correct values the border does not turn green.
Note:
However when we select the field and click outside the field without filling it. and then after filling the correct data border turns green.
However when we tried to achieve it programmatically iterating over each field resetting it and using javascript focus method, that did not do the trick.
I am sure I must be missing some thing. would be able to point out what.

I'm not sure, what you want to achieve. I would need to see some code. If you change the value programmatically you can update the validation ui with the event refreshvalidityui on the form field. If you want to reset the ui, you can either trigger a reset event on the form or resetvalidityui on the form field
$('input').val('foo').trigger('refreshvalidityui');
or
$('input').val('foo').trigger('resetvalidityui');
or
$('form').trigger('reset');
Please let me know, if this helps.
I have a Flexicious DataGrid set up, and I have an ItemRenderer set on a certain column. Now, when I am editing an editable cell, and then stop editing it, the DataGrid fires a FlexDataGrid.EDIT_ITEM_END event (or something like that). When this is fired, I want to do a certain action. That's simple enough. The problem though, is I have a special case:
If a user is editing an editable cell and then clicks away from it (which would cause FlexDataGrid.EDIT_ITEM_END fire), but he happens to click on a button which is within the ItemRenderer set on the column, then in that case I don't want to do the action. I don't know how to make an event work like this though.
Basically I'm looking for an event that is FlexDataGrid.EDIT_ITEM_END_AND_CLICKED_ON_ANYTHING_OTHER_THAN_THAT_BUTTON and I'd like to fire that instead of FlexDataGrid.EDIT_ITEM_END. But alas, I checked the docs and that event doesn't exist =-(.
What can I do? Thanks for the help!
Have you tried ITEM_EDIT_CANCEL? This has a triggerEvent which should have a target property that should tell you what display object the click happened on.
I have been following this example, http://www.ok-soft-gmbh.com/jqGrid/DependendSelects2.htm, as it is just what I need. I have got it working but it doesnt work when scrolling through records. If you bring up the form and scroll from a UK record to a US record, the list doesnt change. The onChange event only fires when the user selects from the select drop down.
Is there a way around this?
Thanks for your help.

My old demo uses 'change' event handler defined in the dataEvents property of the editoptions. In the dataEvents array one can define other event handlers.
You need just bind keyup to the column exactly like it's described in the answer. In the body of the event handler you can do the same actions as in the body of the 'change' event handler (you can place the code in a function and call it from the both handlers). In the way you should be able to solve the problem.
UPDATED: I updated the old answer and another one which was origin for the demo which you used. The new demo support the navigation buttons (the buttons to edit the 'next' or the 'previous' row) in the editing form.
