Blazor hybrid keyboard events on Windows

John 21

Hi,

I'm developing a desktop application using Blazor hybrid and C#, .NET 7. I'd like to listen for hotkeys/shortcuts. E.g., F1. How should this be done ?

(I can't find anything in the documentation. Obviously, I know how it could be done using js but is there a way by just using Blazor ... ?)

Many thanks

Answer 1

the Hybrid app is running in a webview. so it standard browser keyboard handling, via the keyboard events (as as js).

[index.razor]  
  
@page "/"  
  
<input type="text" @onkeydown="KeyboardEventHandler " @onkeypress=" KeyboardEventHandler " @onkeyup="KeyboardEventHandler "/>  
  
<h4>@KeyPressed </h4>  
<h4>@EventInfo</h4>  
  
@code {  
    string KeyPressed = "";  
    string EventInfo = "";  
    private void KeyboardEventHandler(KeyboardEventArgs args)  
    {  
        KeyPressed = "Key Pressed is " + args.Key;  
        EventInfo = "Event Type " + args.Type;  
    }  
}
