I have a DatePicker and an OnAction Handler that perform different works depending on the value of the DatePicker,the date I have to enter is a birthday date and I have to make some work if it is a date of birth of an adult and some other work if it is a date of birth of an underage.
When I change the date using the "Date Picker Menu" my handler correctly perform the work i need , but when i edit TextField the handler not even reacts like DatePicker doesn't acknowledge of this change.
How can i make DatePicker "listening" to edit date using TextField?
You can listen to an editor of your DatePicker object:
myDatePicker.getEditor().textProperty().addListener((observable, oldValue, newValue) -> {
// do something
});
Note, it will be triggered on each typed symbol.

This is a simplified version of my case.
Layout
A choice box with 3 options.
A textarea T1
An input text field.
A textarea t2
Expectation
When the user clicks on an option the selected option is displayed in the T1 instantly.
T2 displays instantly what's currently present in input text field.
Implementation so far
I added a method for onKeyTyped for the text field and #2 works.
I added a method for onMouseClicked for the choice box. #2 doesn't work instantly. It takes another click on the choice box or key press on the text field to display the new value in T1. I also tried onAction and that too didn't work.
For java
inputTextField.focusProperty((observable, oldValue, newValue) - > {
if(newValue) t1.setText(inputField.getText());
});

I have extended the TableCell class to render a date picker. Its graphic is a javafx.scene.control.DatePicker. I have had to do some onKeyPressed handling to handle tab, enter, and escape, and some other customizations to try to get this TableCell acting in a sane way. Now, when I first select the cell which already contains a value, the DatePicker shows up, but it's blank. It looks like startEdit is being called, but that doesn't provide a value to put into the DatePicker. (https://docs.oracle.com/javase/8/javafx/api/javafx/scene/control/TableCell.html)
How do I make the old value of the cell show up in the DatePicker when it first shows up?
Assuming the column type is LocalDate, just call
datePicker.setValue(getItem());
in the startEdit() method.
Does anyone know how to mask the input in a DateField in flex?
Our DateField uses the format DD/MM/YYYY.
Our users want:
to be able to type the date in without having to type in the slash
still be able to use the date selection in the date chooser (the drop down on the date field)
I google’d and found ways to do this with 3 text boxes. I would prefer to have a DateField control. That way the users would be able to make use of the date chooser (drop down) as well.
I would suggest adding a KeyboardEvent to the DateField, and handle the logic of adding or removing slashes inside the event listener function.
I found the best way to do this is onFocusOut I take the text and add the slashes back and reset the formatted text, before any validation fires.

I am using this datetimepicker by Trent Richardson, I can get the date time picker to work, however after the date is changed i need it to be put into a hidden asp.net control that is in an update panel.
So how can i make it so everytime the user changes the date and time it is sent to a label.

So since it seems like it's just a extension of the jQuery ui datepicker, you could use the altField option: http://jqueryui.com/demos/datepicker/#alt-field
or the onSelect Event to do it yourself: http://jqueryui.com/demos/datepicker/#event-onSelect
