I want to call 'onclick' event on listbox. There is 'onchange' event which is called whenever the displayed options changes but I want to call a function when the list box is selected or the displayed option is selected again. Any help is appreciated.
I think by using HTML listbox you cant find Click event. It is Having only change event.Refer This
But You can Do it by some other way Using JavaScript. I found one interesting link Refer This
good Luck.

I need to know how can I get value from dropdown list after I selected it. But I don't need to click the button before pass the value.
You'll need to use Javascript to submit the form after selecting an option.
I can't vouch for this answer but I filed it for future use if I ever wanted to do that. It's beautifully concise.
I have a primefaces autocomplete element which works great except one thig. The problem is that when I enter a valid text (which is mappable to the data behind) but I don't select the element from the propositions, and don't press tab or enter, nothing happens.
So I enter a value and click into another field, the element is not selected and the validation fails. However, I don't want the user to force to explicitly select an item.
My ideas were, that i put an onchange listener to the input element and trigger the primefaces itemSelect event within. But I don't know how to do that, if it's even possible.
Or maybe there are other solutions?
Thanks in advance!
I found a way, although it might not be the most beautiful and easy one.
Maybe it helps somebody...
This is a specific solution for primefaces (5.3), but it should work for other versions too.
$('#form\\:txtAutoComplete_input').val('Foo');
$('#form\\:txtAutoComplete_input').trigger('keydown');
$('#form\\:txtAutoComplete_input').trigger('input');
$('#form\\:txtAutoComplete_panel .ui-autocomplete-item').trigger('click');
For some reason, after the value is entered into the input field, you have to trigger the keydown and the input event in that order. After these events the autocomplete list shows with the matching values. There you have to trigger click on a certain element, so all the backing bean stuff is properly executed.
There is an API for Primefaces widgets.
For instance ;
<p:autoComplete id="gtautoaomplet" value="#{item.soemprop}" completeMethod="#{bean_CrossCheckNew.completeText}" scrollHeight="250"/>
In JS code ;
widget_form_mapingGrid_0_gtautoaomplet.search('foo');
When you write "PrimeFaces.widgets" in your browser console you can see all the widgets available in your page.

Good luck.
I have an unbound form that includes a subform.
The subform is unbound and gets populated when the user clicks on a push button on the main form.
I want to be able to grammatically handle the click even on the sub form and get the data in a specific column. How can I do that? The same thing one would do with VB.NET/C#.NET if you know what I mean.
When I use the properties tab of the subform, I get an expression builder. That does not get me into a sub/function/form or module VBA code editor.
Any help is appreciated.
Edit - Something that worked!
Thanks for the help I got from the answers below.
One way to refer to column in a selected row in a subform is by using this expression:
Me!ChildFormName.Form!ColumnNameInSubForm
EX:
ME!Sales.Form!SalesmanID
Additional Reference here...
A problem with this approach is that the available events On Enter and On Exit don't behave like "click" event does. One needs to focus out of the sub form (by clicking on another control) for either to be triggered!
Look again. The Properties' sheet has a tab, Events. Select any event and select "Event Procedure" from the dropdown and click the ellipsis - that opens the code editor.
Refer to sub-form control form main-form event handler (VBA Sub):
Me!Subform1.Form!ControlName
Me is self reference to the main-form, Subform1 is the control containing the sub-form, Form is a reference to the sub-form, and ControlName is a reference to the field on the sub-form. ! is a short way to refer to a control in a form's contrls collection.
A longer way to write the above would be: Me.contrls("Subform1").Form.Contrls("ControlName")
Refer to a main-form control form a sub-form event handler (VBA Sub):
Me.Parent!ControlName
Me is self reference to the sub-form, Parent is a reference to the main-form, and ControlName is a reference to the field on the main-form.
A longer way to write the above would be: Me.Parent.Contrls("ControlName")

I have a database with many forms, when I added a button with an onClick event to one of them it just doesn't work. The onClick event code is very simple:
Private Sub button_Click()
DoCmd.Close
End Sub
Doesn't matter how I click it, the event is not firing. I put a break point in front of the sub, and realized that when I clicked the button the event is not even firing. I create buttons in other forms they work fine, its just this one specific form that doesn't work.
I did some testing, and realized that when I make the form into a split form, the button stops working.
Any Idea why?
Thanks
Nvm..it seems like there has to be at least one field in the split form for the button to work. Did not know that before
Then maybe the function is not linked to the button.
did you checked that in the button properties "on click" has the vba function linked?
the buttom name and the function im vba are the same? "Button"?
The Command Button Wizard create a command button that performs a specific task. In an Access (.accdb) file, the wizard creates a macro that is embedded in the OnClick property of the command button. In an .mdb or .adp file, the wizard creates VBA code, because embedded macros are not available in those file formats.
This might not be quite relevant to your question but might help someone else in the future where an event is not firing....I had a similar issue in an Excel form where an event was supposed to happen when I click a button...I deleted the button and added it again and it worked...could be a bug or a file corruption...try deleting then adding the control again.
I am using a editable datagrid and want to autosave the edited information in an editable column. Also, since its a simple text editing I don't want to use itemEditor/Component for the same. I was hoping to have a focusOut event but I dont see any focusOut event for datagrid column(even if its editable?). What event should I be using?
Thanks.
I got it working by using itemRenderer in which I used a text box and handled it with textbox's focusOut property. Still wondering how could I have done it directly from dataGrid's event.
