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
Ok, a rather specific question which requires additional explanation and context.
Context
We are POCing a "try-convert" from a bespoke language to .net core (5 currently) and blazor server. Server because it allows a try-convert scaffolding we can build security concerns round. The details of this are not important. It just explains why we have some constraints which may seem unrealistic under normal circumstances.
I am fully accepting that "no you can't" or even "no you shouldn't" is the likely outcome. We are exploring possibilities.
Question
The concept of a circuit in blazor is a really good fit for the presentation layer. We would like to store information at the scope of the circuit.
The obvious solution is to use a scoped service in the dependency injection container.
E.g. In my Startup.cs I can put
...ANSWER
Answered 2021-Jun-12 at 12:56As far as I understood both your question and the Blazor concepts, the answer to your question is « no ». There is no possibility to retrieve statically the current HTTP context in Blazor. Because you never know if the context is an initial page load or just SignalR communication to update the current page. Here is the manner I save this situation:
Create a cascading parameter that is shared by all razor components
This cascading parameter is a class with many information coming from initial HTTP request, caught in the _Host.cshtml from the httpContextAccessor.HttpContext
This cascading parameter class gets all the methods of my previous static methods.
These methods can use the properties of the cascading parameter: RawUrl, UserAgent, ClientIp, …
This implies hard refactoring work to migrate legacy ASP web sites. But the performances of Blazor are worth it.
QUESTION
I somehow extended the gmock test case from donsoft.io's example, and made it as follows:
...ANSWER
Answered 2021-Jun-11 at 15:07Define dependencies(The random generator here) as local variables are not recommended, it's much harder to do dependencies injection(Or it won't be possible), so I change the functions Rng_t into template function and pass the Rng as a parameter.
In practice to construct a random generation may be heavy work, it needs to initialize its internal status, to construct it every time we call the function flipCoin is waste.
The non-virtual function can be mocked, one most commonly used strategy is to use the template, here we make the class CoinFlipper's member function as a template function, then we can test the dependency with our MockRng.
Be aware that for the template function, we need to define the member function in the header file.

QUESTION
I've got a grid layout with 2 columns and 3 rows.
I want to be able to resize the column widths. I know I can use resize: horizontal but that only changes width for one row.
I'm thinking I can't do what I want and I'll need to use nested grids but I'm not sure so I wanted to check.
...ANSWER
Answered 2021-Jun-11 at 21:50You can do it with your structure. The trick is to use auto 1fr on the template columns and set the initial width of the resizable element to be equal to 50vw to simulate the 1fr 1fr initially:
PS: I simplified the code by removing the areas but that's not part of the trick, you can keep it

How can I resize a * column in the XamDataGrid? In this example, I cannot resize the department column.
MWE: MainWindow.xaml
ANSWER
Answered 2021-Jun-11 at 11:06Setting the department field to Width="*" prevents it from resizing. To enable resizing of this field it is necessary just remove the width setting in this column.
QUESTION
So, I have this big application that does some long work on the UI Thread. I know it's bad design, but this can't be changed. Thake it as a constraint.
To show the progress of the work, I want to show a WPF dialog with a progressbar. The dialog is using DataBindings to DependencyProperties for its labels and the progressbar.
When I first called Show() on the dialog instance, the dialog wouldn't be displayed, because the Dispatcher is busy working on the long running task. So I called Dispatcher.Yield() after Show(). I also call Yield() after each update of the DependencyProperty of the progressbar. The dialog windows is showing up, but it's still very empty. The DataBindings are not updated on Dispatcher.Yield().
Is there any chance I can get them to update while the Dispatcher is busy?
Example AppCreate a new .NET Framework WPF App, name it 'BusyProgress' and change these files.
MainWindow.xaml ...ANSWER
Answered 2021-Jun-11 at 09:47Building the example helped to realize that this answer was in fact enough.
My app had another constraint that I didn't realize before. The Dispatcher was disabled -.-... Thank you sintar for your help!
QUESTION
Why introduction text was overlaid by the profile image when the browser was scaled down to 650px? They suppose to show in 100% width at 650px screen. I did adjust the position of .speakers-info from absolute to relative, it seems solved the overlay problem but then all position setting got messed. Please see the code as below and advise how to solve it, thank you!
...ANSWER
Answered 2021-Jun-11 at 08:26First, yes you should change the position to relative. Second you set the width to 100% and in combination with position: absolute it overlaps the other content. You should set another "col" class or add a width property to the .speakers-info below 768px. Here I didn't set the width, just changed position property and added margin to distinct the avatar from the name:

PHP requires the Visual C runtime (CRT). The Microsoft Visual C++ Redistributable for Visual Studio 2019 is suitable for all these PHP versions, see visualstudio.microsoft.com. You MUST download the x86 CRT for PHP x86 builds and the x64 CRT for PHP x64 builds. The CRT installer supports the /quiet and /norestart command-line switches, so you can also script it.
