DotVVM Minutes #3: Handling Enter and Escape keys in DotVVM

In order to provide good user experience for the users, websites should handle standard keys like Enter and Escape properly. In simple scenarios, you can just place the content in the form element and use the submit button, but you need more sophisticated tools in complicated situations like GridView inline editing or modal dialogs.
In this video, I'll write a custom Knockout binding handler which can handle Enter and Escape keys on any element and press the correct buttons. Then I'll wrap this functionality using DotVVM attached properties to provide IntelliSense in the markup.

Píšeme AskMe v DotVVM #2

Z Altairových kurzů a konferencí znáte ukázkovou aplikaci AskMe. Je psaná v ASP.NET Core a je k dispozici ve dvou variantách, v MVC a v Razor Pages. Je dostatečně jednoduchá, aby mohla sloužit jako demo a příklad, ale zároveň dost složitá, aby to nebylo jenom "Hello, world!", ale aby se v ní řešily real-world problémy.

Na tomto live streamu jsme pokračovali v přepisování této aplikace do DotVVM a vysvětlili si, jak funguje data-binding na server, jak fungují validace a jak napojit přihlašování uživatelů..

DotVVM Minutes #2: Calling Azure Functions from DotVVM

Azure Function is a popular serverless technology and you can simply expose your functions as a REST API.
In this video, I'll connect my DotVVM application to Azure Functions using DotVVM REST API Bindings, a new feature introduced in DotVVM 2.0.

DotVVM Minutes #1: Using Bootstrap 4 in a DotVVM app

Bootstrap is a popular CSS framework which lets you create nice looking websites without advanced graphics skills.
In this video, I'll be using Bootstrap 4 in a DotVVM app, with and without our commercial controls.
You'll see a few nice Bootstrap controls like ModalDialog, DateTimePicker and more...

Je dostatečně jednoduchá, aby mohla sloužit jako demo a příklad, ale zároveň dost složitá, aby to nebylo jenom "Hello, world!", ale aby se v ní řešily real-world problémy.

Během tohoto live streamu jsme naprogramovali první část této aplikace v DotVVM a vysvětlili si, jak DotVVM nainstalovat do projektu, jak vytvořit master page a jak do stránky dostat data z Entity Frameworku. Trochu jsme se zapotili při implementaci stránkování, ale nakonec jsme se zase úspěšně rozmotali.
