The docs doesn't mention this, but does anyone know if it's possible to only show the DatePicker on icon click (or button), and not when the input field receives focus?
Users will primarily enter dates using the keyboard and doesn't want the DatePicker displayed, unless specifically asked for.
You can have a look here for the complete API which has some options that are not documented on the AntDesign site. But there is no option to achieve what you are looking for.
You need the combination of a text input with a button to popup the picker, which is a different paradigm from the one <DatePicker> uses. It could be "hacked" by combining a normal <Input>, <DatePicker> with custom CSS that only shows the button, and some Javascript event handlers.

I want to know the event in blocks section using which the entered text value can be obtained without a form submission through button.
Let's say user inputs text in mobile phone through keyboard and presses enter. In this case I want some event to trigger and get the value that user entered.
There are 2 events available like lostfocus and gotfocus.
Will these work? Or is there any other good approach for getting text value on pressing enter?
Unfortunately there is no such event like OnEnterPressed available in MIT App Inventor and the events LostFocus and GotFocus will not work in this case.
What you currently can do is
use a button and use the Button.Click event, or
create your own custom keyboard, see also this example
Currently there is a limitation for App Inventor extensions, which only can be used for non-visible components. Later as soon as also visible components are doable, then you could write your own textbox extension and add an event yourself.
Edit concerning the new question in the comments about different screens:
Use different screens wisely
Before starting to create another screen, first you should think about is it really necessary? See also Building apps with many screens and SteveJG's post about advantages/disadvantages, because in only one screen you also can use vertical arrangements to simulate different screens, just set the arrangements to visible = true/false as needed...
You can insert a Clock component that monitors the TextBox1.Text. When it triggers, it checks if the TextBox1.Text has changed and saves it to a variable. When it triggers again, it compares the variable with TextBox1.Text. After the user finishes typing, the variable and TextBox1.Text will be equal and then you can trigger the event like you eanted when the user pressed Enter.
Hope this helps!
When I use this setting I have one in a form in a dialog, and one in a form that is in a popup. The dropdowns look different.
When data-native-menu="false" the dropdown in the dialog appears in another dialog, which actually looks quite nice. I assume this will allow a more consistent look and feel accross devices.
However when I use this setting data-native-menu="false" on a Select in a popup it does not show the standard select, not the dialog.
Thanks
There's a good reason for this.
As you can see there are 2 kinds of select widget. First one uses native looking select box (one showed with data-native-menu="true"). Other one still uses native select box but it hides it and shows custom jQuery Mobile select box widget (one showed with data-native-menu="false"). This jQuery Mobile widget is shown as popup. This is important point.
Second, mentioned problem is unsolvable, at least from the point of current jQuery Mobile framework, and here's why. In few words, when working with jQuery Mobile popups, one popup can't open another popup. Two popups can exist in the same time. Thou you can always close one popup before opening another one, but this is not usable in your case. Because jQuery Mobile select widget is popup it can't be used inside classic popup widget.
If you don' believe me you can find it in official documentation here, just search for text: "Chaining of popups not allowed". And you will see this text:
The framework does not currently support chaining of popups so it's not possible to embed a link from one popup to another popup. All links with a data-rel="popup" inside a popup will not do anything at all.
On the other hand, dialog is a variation of a classic jQuery Mobile page, just with large margin and semi transparent overlay. It can be used to show popup, just like normal jQUery Mobile page.
I am currently using input text fields that spawn a chooser (listview with various entries) when they are clicked on. Testing this on the appMobi emulator works flawlessly; however, when testing it on an iPhone, the default keyboard appears when the text fields are touched and then quickly disappears to be replaced by the chooser.
Is there a way I can prevent the default keyboard from showing with JQM?
If they require user input, then you can't prevent the browsers' default implementation (at least in a x-browser friendly way). They is certainly no solution with JQM.
I suggest you style your own text box from a div or similar, using html/css. With js you can then wire up the chooser to this element.
SO I have a select box that I fill dynamically. I discovered that once the SELECT gets longer than the page, it automatically becomes a dialog listview.... which is TERRIBLE!
When this happens, the page refreshes when the dialog is closed and my whole page starts over....
Has anyone experienced that and do you know how to shut it off?
Thanks!

You could use the native look and feel?
http://jquerymobile.com/demos/1.0.1/docs/forms/forms-all-native.html
Native form elements & buttons Although the framework automatically enhances form elements and buttons into touch input
optimized controls to streamline development, it's easy to tell jQuery
Mobile to leave these elements alone so the standard, native control
can be used instead.
Adding the data-role="none" attribute to any form or button element
tells the framework to not apply any enhanced styles or scripting. The
examples below all have this attribute in place to demonstrate the
effect. You may need to write custom styles to lay out your form
controls because we try to leave all the default styling intact.
I have a date field on a PHP website and I'm using jQuery Mobile for mobile site.
While browsing the site on a mobile browser, (eg firefox mobile on android), on clicking on the date text input, the calendar dialog comes up, but the soft keyboard also comes up on my android (Soft keypad comes up whenever one focuses on a input field)
Is there a way, I can force hide the soft keyboard ? Is there a generic javascript based trick to force hide the soft keypad (that works on all mobile devices like iphone, android etc ?
I'm using the jQuery Mobile datepicker from here
TIA
A more simple solution is to add readonly="true" to the input boxes that you have the datepicker attached to. Even though you can't manually type in a date, on mobile you won't have to deal with the keyboard popping up and getting in the way
Just found an answer to my question. (Guess I didn't search with the right keywords earlier :-|)
Adding a jQuery blur event on focus solves the issue.
Thanks to this post by Danny C
My workaround (though I am using a different plugin: the datebox from jtsage.com) is currently the following:
set a disabled attribute on the input
bind a click handler to the input or its parent
the click handler triggers .datebox('open') on the selected element
This way there is no focus element so no triggering of Android soft keyboard.
add the readonly attribute to your date box. (or readonly="readonly") input type="text" data-role="date" readonly
For JQM add the folloiwing files jqm.datepicker.css , jqm.datepicker.theme.css , jqueryUI.js , jqm.datepicker.js
