I have a question and tried everywhere in world wide web. So this is my final destination.
I am developing an application (ETRM related) using javafx8 which is actually an application which is already developed using c# with wpf in my company. But the performance is not so good. so i'm trying to do it using javafx so that i can learn few things at the same time i will get some real application development experience.
Problem: (screen shots attached)
I open my application and i enter a trade number in a text field and say open. it should open the trade from db.
Here Trade is my domain entity which has many properties. for eg: a trade entity have a quantity, buyer and seller etc where buyer and seller are also domain entities.
So i open a new trade (first screen shot) and select the properties using the comboboxes and save the trade. this is the flow.
The first block what u see are all properties of the Trade entity**("Trader", "Type", "Contr. Status", Counterparty, etc).** It all loaded with default data. Now when i change any value, for ex. the "Trader" to "ABS" (2nd screen shot) it calls the "trader" property in the "Trade.cs" file (3rd screen shot) and sets the value. it is because the whole block or more precisely the whole tab what u see "Trade#: New1" is bound to the Trade entity at the window creation time itself, so that whenever u change any property on the screen it exactly call the respective getters and setters.
It is done by setting the datacontext of the tab to the trade entity in C#.
I want to achieve the same in javafx. I designed the UI exactly and populated all the data from DB to show in the comboboxes but dont know how to set the datacontext to the UI.
In C# i can bind my domain entity (trade) to a window and whenever i set values on the UI that gets set on the trade entity. datacontext may be the C# term but i want something similar in javafx.
Will it be possible to achieve in javafx?
Thanks in advance. Please let me know if u need further details.

I want to retrieve data from Sqlserver database with EntityFramework core and do crud operations and show data table to client without refreshing the page (Realtime) , is there any source or example in this case ?
Not sure there is a definitive source for this, but it's not that hard to build yourself.
It should be relatively straight forward. In general you'd need
A model for the grid that defines the properties to show and edit, and also which row is selected.
An HTML Helper to change the rows from read-only to editable
A view to display the table.
An [edit] action link for each row enables you to select a row by ID for editing, and after clicking it, reloads the page and then the view can respond accordingly to change the type of the row from read-only to editable.
You could use Blazor or maybe Ajax to change a row from read-only to editable without refreshing the page, but I'm not sure if you need to meet certain requirements that discard using either of them.
John Ciliberti has written a recipe for a book, that works just like I described, find it on his Github page to get some ideas of what's involve.
If you need a more out-of-the-box solution, perhaps consider wiring up DataTables.js.
I'm just starting to get into Access due to my job and am tasked with creating a form that displays Data for the individual users on load. Basically what it needs to do is to get data from 3 tables, join them together, and then display the found rows that match that person's accounts they are responsible for managing.
I have this working via a single table Query using a listbox and a datasheet view, however, being a web developer by trade, I would like functionality that displays items similar to what a Unordered List(UL) would display and with functionality that allows the user to click on the company name(which acts as a hyperlink) to then update the information in a new form that I have built, by loading that data into the form, and allowing them to update the fields that I have designated as changeable.
Is this possible in Access via a form or would this be too difficult to implement? I'm decent with VBA, still learning what a lot of the things do, but as far as the logic and things like that to make something happen, I can do that no problem. These rows all have a unique ID so I would be able to either keep them in a collection to populate the form data or I can simply requery the data using the ID number for loading the form data.
A listbox performs like a combobox in datasheet view. Did you mean you have a combobox?
Actually very simple to accomplish, and various methods available. I assume you have a form bound to your Query with a combobox that lists companies. Controls have events. Use the Click event of the Company control. I use only VBA (not macros but macro could do this). Select [Event Procedure] in the event property. Click the ellipses (...) to open VBA Code Editor, type code into the procedure:
DoCmd.OpenForm "CompanyInfo", , , "ID=" & Me.tbxCompany
Keep in mind, controls used for the purpose of entering/selecting filter criteria should be UNBOUND, otherwise you would change data in record. However, using the Click event of a BOUND combobox (as long as you click on the box, not the dropdown) or textbox will not change existing data, not so for a listbox.
is it possible to have a onepage-form for editing or creating a entry and its related (1 to n) entrys?
For example: I have a customer model, every customer can have unlimited addresses. I could now have a CustomerCrudController and a AdressCrudController with the adress having select2-field for the customer, maybe having some kind of filter for the customer in the adress-list-view but it would be a more fluid working having the ability to change or add adresses in the customers-edit-view.

There is currently no built-in way to do that right now in a Backpack CRUD create/edit form. It's planned, but will not be happening until the next version of Backpack, which might take as long as 3-6 months to launch.
What you could do is:
1) create your own custom field type, say "select_or_create_address";
2) start from the select2 field type and create your custom functionality:
the results should could be loaded with ajax;
a button next to the select could open a popup with the create address form, either:
a quick form you code yourself that inserts a new address in the db;
the AddressCrudController create form (but without the menu, sidebar, etc); for this you'd need to create another method in the AddressCrudController, base off CrudController::create() but loading a different view;
when the address successfully added, the id should be inserted in the select2 as a value;
My recommendation is to go with the quick form, it should be faster to develop and you wouldn't have to resort to solutions like iFrame popups.
Cheers!
Every time I try to create my own form, without using a form wizard base off a table/query, it doesn't seem to work with the subform even thought the forms are connected correctly via master/child links. I tried comparing my dropdownlist/form properties from a wizard version to a custom made. I don't see any difference, why would one work while the other doesn't? am I not seeing something in the background?
Is the form / dropdownlist record source not inter connected in my custom form?
EDIT:
My combo box is now updating the first subform correctly, but it is based off a wizard form. My problem now is getting the subform1 to update subform2. I know I should be creating a new thread. But do you mind taking a quick look. The second subform should be retreiving the ID from subform1 and link it to workOrderID in subform2.
The relationship
Do not be fooled by my workOrder, it is design for only 1 LotNo. However it was originally design for multiple but was change so the user can only enter 1 lot number for 1 work order.
The main form + 2 subform
Subform1 is the first to the top
Subform2 is the bottom one
The links between subform2 and subform1. Subform1 is the first one to the top in the previous picture.
I'm trying to create subpanel in Account detail view where list of elements is fetched from external REST service.
I know how to define subpanel, but have no idea how to fill it with data from external network source. Was trying to use get_subpanel_data but there I can only change SQL.
Any ideas how can I do this?
When I've done this in the the past, at least with Sugar 6, I opted distinctly not to try to create a true subpanel. The data being loaded is coming from an outside source and is loaded dynamically with the page, so why present it as if it's static data coming from Sugar? Instead, I created a custom Smarty template to use as the footer on the detail page. For such an example, you can check how it works on the Calls Edit View. I think it's the footerTpl parameter in the detailviewdefs.php or editviewdefs.php. I loaded the smarty template by creating a custom detail view for my module, so custom/modules/MyModule/views/view.detail.php - extend the base Detail View class and override the display to feed Smarty new params, then your Smarty template only needs to iterate through and present the data that your view defined.
To be super-hip and abide by MVC, you could even put your custom code into your bean (if it's a custom module) or into a custom controller method, then reference that from the view.detail.php, and still feed it from there to the Smarty template.
Alternatively, you could just load JavaScript into the Smarty template and use the JavaScript to call the third-party service, parse and present it, etc.
I realize this question is a little bit old now however it comes up fairly often so why not provide an answer with a couple possible solutions. I won't get into code but more just into the design theory of how it can work. If someone needs more specific code help then that is another question.
A couple ideas...
As you mentioned you can define a custom Function which will load in Data to the SubPanel from your own SQL Query. That is one method that I just recently got to finally put to use after knowing about it for a good year and a half.
When you go this route, you are restrained to using the Columns in the SubPanel. I assume it is using the actual Metadata files to determine which Field Columns a SubPanel can use so you pretty much need your custom data in a Database table to have the same column names as the fields defined in the SubPanel Metadata.
Obviously this works great in the right situation, however not always and that leads us into the 2nd method I know of.
The other way is pretty much what #Mattew-Poer mentioned in his answer. It means abandoning the SubPanel altogether and instead generating your own HTML. This is by far my favorite and prefered way of doing it and I have been some really custom modules due to this being possible in a custom module! I will show an example below.
(Click HERE to View full size image)
In the screenshot, you can see in this example that I have something looking Similar to a SubPanel however it is not and is much for flexible and easy to customize.
Example, to the far left column in my fake subpanel is image checkboxes. When clicked on, an AJAX request is made to change the Task row Status.
After that, the checkbox image is updated to indicate the new Status state, the Modified DateTime is updated, the Status column has color background SPANS and is also updated with the correct text and background color when the left side checkbox is clicked.
Doing any of this with the standard SubPanels is a complete nightmare and would be difficult to do some of the stuff that you are open to do when you build your own version of a SubPanel.
With that said, I have built an identical clone of the above screenshot using SugarCRM default SubPanels! It was a nightmare. I could easily update the content and HTML in some of the columns. I even had the AJAX click checkbox image to update and do all the other updates I mentioned above. It wasn't too hard and worked fairly good but it had some issues.
When you do inline edit, inline create record, or subpanel paging to load different set of record. You would then lose all the custom HTML formatting that was applied. The reason is, in the SubPanel you are limited to using the After UI load logic hook. So since the "Page" is loaded already, when an AJAX request is made to add/edit the subpanel content or load a new set of items with the paging links. It only loads the SubPanel content on those events and the whole Page content does not reload. Because the logic hook only fires off 1 time after the page loads, this newly loaded subpanel data doe not receive any of your custom HTML formatting.
In my case, this means that nice looking colored background Status spans are lost, the image checkboxes are lost, and some other functionality is lost.
Now to get super technical, I could have gone another 3rd route and instead made new Custom Field Types for each SubPanel filed that I needed to apply custom HTML to. This process is super hard in my experience and in some cases it really isn't the BEST solution.
Because of the reason explained, this is why my new modules use the Custom HTML route to generate my own version of a custom subpanel or whatever Data is needed in my Module pages! So far it is working better than I imagined and has opened doors for me to build custom SugarCRM modules that I previously didn't even realize would be possible to build due to some of the issues I mentioned above. Now I bypass them altogether and open the door to do pretty much anything!
I've got some really cool stuff for SugarCRM in the works right now. If anyone has any questions feel free to ask in a new question or for me personally in a comment here.
