I implemented JDatePicker exactly according to the post below. It was working fine for the longest time, but recently when I tried to click on the button to change the date, it doesn't seem like the button is recognizing the action and the calendar window isn't displayed. I added an ActionListener to the date picker to test this, and the code is not being run. I have additional buttons that will change the date by one day earlier or later, and those will likewise update the calendar model in the label of the date picker as advertised.
The problem is only occurring in my main class; if I add it to another class, it works fine. I've tried different implementations of it, but with no luck. All my other buttons in the frame function normally, it just seems to be isolated to this one component.
What would cause it to not function?

The title says it all: I have a JavaFX DatePicker and am looking for a way to add a button which, upon a click to it, goes to the current date or at least the current month.
Is there a way to do this?
BTW, I'd like to have this button inside the DatePicker, maybe above the month calendar.
Do I have to modify the skin?
I believe this would work for you
datePicker.setValue(LocalDate.now());
Inside the button action function you can add this code to set the datepicker to the local date
I've ran into a problem. In one section of my page I have a date with today's date. If the user clicks on an arrow to the right it goes forward a date and if they person clicks an arrow to the left it goes back a date. On the arrow buttons I am using setState. The date changes perfectly fine.
I also have a form below on a separate card. To each textFormField I h ave a controller set up. I had to set these up because initialvalue: only gets called once so the fields were never changing with the date.
Anyway the fields now change with the date and it is correct. But the moment I click on the form, The top widget date shoots back to the initial value it was at?
I checked this by setting up a didUpdateWidget override and this is firing every time I click on the form field??? Why is this happening. I am not updating anything yet.
When I used a controller for the date value displayed between the two arrows it doesn't change but when I hit submit the value it's supposed to be assigned to is the wrong (very first date that appears). So it seems like when didUpdate fires it is setting that field which I have set in my extends StatefulWidget class{}.
EDIT: Wow typing that last sentence made me realize I needed to set the value in my bottom class that extends State<>. I was using it with widget.activeDay.
I guess I'm still curious as to why this is happening with the text form field though?
Clicking on a text-field opens the keyboard.
This changes the screen dimensions and leads to MaterialApp rebuilding the route.
The route rebuilding ultimately calls didUpdateWidget on that specific widget.
I have a single ViewController which contains a Table View on the left and a few labels on the right. Navigating through the table view entries works fine (up/down). Focus is no problem there. Even the related text in the labels is updated just fine using tableView:didUpdateFocusInContext.
The interface looks like this:
However, the button on the right ("Jetzt ansehen") never gets focus. When I use the debugger (as suggested in the official documentation), it doesn't include the button in the focusable area at all:
I really tried to solve this using UIFocusGuide, but I have no real idea how to accomplish that, yet.
I've created a query to use in an AutoCompleteBox and it works as expected when the user select the AutoCompleteBox in the grid as shown in the picture below
However if the user click the plus button to add a new record using the predefined Add Dialog then the query and the AutoCompleteBox's format doesn't work as shown in the picture below
Why is this happening and how I can fix that?
Thanks
I haven't yet found a way to edit the default Add New dialog.
Instead, make a new screen, select the "New Data Screen" template, and link it to your entity data. You can customize the screen to fit your needs, even make it a Modal Window by changing the Control Type in the screen properties. Once you have the screen set up the way you want, go back to your grid screen, and double click on the Add... command in the Command Bar of your grid, to edit the AddAndEditNew_Execute code. In that method, call your custom screen.
So, as I got to thinking about this some more, I came back to the thought I had when I tried to do this a few months ago. There has to be a better way, so I Googled it again.
This time, I found something. He's using an old version of Lightswitch, but I've successfully applied his technique in my application built in Lightswitch 2012.

I have experience in Android and currently started to learn iOS. I created a mechanism to Pick data in an Android App. When I click on Date button, a DatePicker pops up:
As you see It has Cancel and Set button.
My question is about my iphone App. I want to have the same mechanism. When I click on the button, Date picker pops up (that can have Set and cancel button like Android Date picker). How can I do that? I'm not sure that it is a good way in iPhone, Can you help me if we can design a better mechanism?
Here's a UX comparison between Android and iOS standard widgets, with links to the documentation on the relevant Apple / Android websites. It's a nice way to get started learning all the technical terms.

Hopefully that gets you started.
Apple has a sample project that demonstrates this. You'll have to adapt it slightly: instead of showing/hiding the date picker itself, you'll want to show/hide a view containing a date picker and a dismissal button.
It's called DateCell.
Basically, it treats the date picker as if it were the keyboard for a cell containing the date. You'll need to manage hiding it when the user enters a text field (and thus, needs the real keyboard) and scrolling to keep the date row in view, but all the bits you need are in this project one way or the other.
One way to do it would be add a custom buttons to the same view containing date picker and then pop it up when the users wants. Instead of using the date picker delegate use the buttons action to get the date picker value.
