Prism is a framework that helps you make frontend web applications with Ruby and WebAssembly. It uses mruby and emscripten to compile ruby code to WebAssembly. It also provides a runtime layer for working with the DOM and events. ️ Prism is currently in extremely early alpha. Expect bugs, breaking API changes, missing functionality and rough edges. ️.

QUESTION
I have a WPF app, linked to a SQL-server. I am using the MVVM-light package (I do actually have Prism.Core installed, but I'm not sure if I'm using it or not.... new to MVVM).
There's a DataGrid, bound to an ObservableCollection.
I have been trying to implement the PropertyChangedEventHandler, but I can't seem to get it to work.
I have a Delete button bound, and I am able to remove rows, but when I re-open the form, the changes does not carry over.
I tried to change the binding-mode for the DataGrid from OneWay to TwoWay. With OneWay, the changes does not carry over when I re-open the form. With TwoWay, I get this error message when opening the child form (which contains the DataGrid):
System.InvalidOperationException: 'A TwoWay or OneWayToSource binding cannot work on the read->only property 'licenseHolders' of type 'Ridel.Hub.ViewModel.LicenseHoldersViewModel'.'
So, If I then add a set; to my public ObservableCollection licenseHolders { get; },
the program runs, but the previous problem persists, like it did when there was a OneWay mode configuration on the DataGrid.
What do I need to do to get this to work without communicating directly with the Sql-server, which would defy the whole point of using this methodology in the first place?
ANSWER
Answered 2021-Jun-15 at 13:26You are confusing topics. The VM needs InotifyPropertyChanged events, which you have but are not using, to notify the Xaml in the front-end that a VMs property has changed and to bind to the new data reference.
This is needed for Lists or ObservableCollections. Once that is done, the ObservableCollection will then send notifications on changes to the list as items are added or removed.
Because you miss the first step:
QUESTION
I am developing a modular WPF application with Prism in .Net Core 5.0 (using MVVM, DryIoc) and I would like to have a module that is not a WPF module, i.e., a module with functionality that can be used by any other module. I don't want any project reference, because I want to keep the loosely coupled idea of the modules. My first question is: is it conceptually correct? Or is it mandatory that a module has a screen? I guess it should be ok.
The second and more important (for me) is, what would be the best way to create the instance?
This is the project (I know I should review the names in this project):
HotfixSearcher is the main class, the one I need to get instantiated. In this class, for example, I subscribe to some events.
And this is the class that implements the IModule interface (the module class):
ANSWER
Answered 2021-Jun-14 at 18:20Or is it mandatory that a module has a screen?
No, of course not, modules have nothing to do with views or view models. They are just a set of registrations with the container.
what would be the best way to create the instance?
Let the container do the work. Normally, you have (at least) one assembly that only contains public interfaces (and the associated enums), but no modules. You reference that from the module and register the module's implementations of the relevant interfaces withing the module's Initialize method. Some other module (or the main app) can then have classes that get the interfaces as constructor parameters, and the container will resolve (i.e. create) the concrete types registered in the module, although they are internal or even private and completely unknown outside the module.
This is as loose a coupling as it gets if you don't want to sacrifice strong typing.
is there a way to get rid of that
var searcher = containerProvider.Resolve();and a better way to achieve this?
You can skip the var searcher = part :-) But if the HotfixSearcher is never injected anywhere, it won't be created unless you do it yourself. OnInitialized is the perfect spot for this, because it runs after all modules had their chance to RegisterTypes so all dependencies should be registered.
If HotfixSearcher is not meant to be injected, you can also drop IHotfixSearcher and resolve HotfixSearcher directly:
QUESTION
I am using a Telerik RadNumericUpDown control in a C# Prism MVVM application. When my users hold down the up or down arrow the control increments the value of the property it is bound to. However, when that property value is changed, a command is sent to another device over a communications line with some latency. Also, there are instances where the device doesn't succeed in changing the value of this parameter.
Here is the code from my view.
...ANSWER
Answered 2021-Jun-11 at 09:07How about disabling the control while the external device request is pending and enable it again, when you have a response and the correct value is known? Each control deriving from UIElement has a property IsEnabled, that you can use to deactivate user input (control appears greyed out).
Gets or sets a value indicating whether this element is enabled in the user interface (UI) [...] Elements that are not enabled do not participate in hit testing or focus and therefore will not be sources of input events.
You can create a property IsExternalDeviceNotPending in your view model. and bind it to the IsEnabled property on RadNumericUpDown. Note the ..NotPending (is enabled means no external device pending). If you wanted to make this a positive condition (...Pending), you have have to use a value converter in XAML to negate the value, so this is simpler.

I am using a plugin that is creating a custom payment type where the user can fill in a custom payment ID. The thing is, I want that custom payment ID stored in an ACF field as post meta on the WooCommerce order edit page. I have created an ACF field named 'kkpayment' for this task. I figured the rest should be done using update_field($selector, $value, [$post_id]);. I have created a PHP function for this task. However, my code doesn't seem to work.

QUESTION
im currently digging through the github page, but Im unable to figure out how to set the tabSize property on my prism editor, if anyone has any experience and is willing to share it I would greatly appreciate it!
...ANSWER
Answered 2021-Jun-01 at 18:26I will answer here as I placed in code snippet for you to play with.
There is a problem on the umd script where it cannot recognise tabSize as a valid props.
Therefore, you can use tab-size to overcome this.
P.S. move tab size to be part of vue data to avoid complaining the type.
Here is the code snippet for you to test it.
QUESTION
Hope everyone is safe.
I need help implementing INotifyDataErrorInfo interface with SfTextBoxEx placed inside SfTextInputLayout.
WPF with MVVM using Caliburn.Micro framework.
Please find following project structure to understand by question.
1) FolderName : Infrastructure File : ValidatedPropertyChangedBase.cs
--It contains implementation for INotifyDataErrorInfo.
2) FolderName : Model File : TestModel.cs --Contains two properties with inherited from ValidatedPropertyChangedBase --Also contains the class for Validation of properties using FluentValidation
4) FolderName : View File : HomeView.xaml --Standard window with two SfTextInputLayout with SfTextBoxExt
4) FolderName : ViewModel File : HomeViewModel.cs --standard view model with Model as property with Validation triggering. --Here if i put breakpoint on validation method i can see that error returned is correct but somehow it is not triggering the UI to show the error message. --I've already set ValidatesOnNotifyDataError=true while binding the property with textbox.
Please check and guide me if something is wrong. NOTE : I am using syncfusion controls but I tried with standard text box also, it is not triggering the errorchanged event.
Also I've used IntoifyDataError implementation from: https://www.thetechgrandma.com/2017/05/wpf-prism-inotifydataerrorinfo-and.html

I have a SignalR service and an Uno Platform WASM Client (with Prism). I want to call a hub method, which returns a model. The problem is, i have two identical models (Properties, Methods, etc.) but the client can only receive one of them upon calling the hub methods. With the other model a exception gets thrown on deserialization.
Hub:
...ANSWER
Answered 2021-May-30 at 01:40This is a generic issue related to the IL Linker step, which removes members that are detected as not used, in some cases incorrectly when reflection is used.
You will need to add linker descriptors to fix this in the LinkerConfig.xml file in the WebAssembly project, likely in the assembly that contains the ReservationManagement namespace.
You can find additional documentation about the linker configuration here.
