How to avoid clicked key auto-repeat in blazor server?

Jawe 21

I just want to know if a key is clicked or not and not waste server resources when it is.
Right now, i check the 'repeat' event property in client js code and use js-interop to inform blazor of clicked keys.

Is there a blazor built-in way to do this, without me having to mess with js?

Hi @Jawe ,

Can you create a simple sample to explain more detail what you want to do?

From the Built-in event arguments, we can see the KeyboardEventArgs class has the Repeat property, if a key has been depressed long enough to trigger key repetition. this property will return true, otherwise it should be false. So, you can try to use this property to avoid clicked the key auto-repeat.

The 'repeat' check is done on the server, right? I think this puts unnecessary strain, that can be avoided if you check the property in javascript code.
I'm asking if there is a built-in way for this common case, where blazor checks for auto-repeat only on the client.

I'm making a game, where key repetition from all users is the norm.

Hi @Jawe ,

Agree with you, we'd better check for auto-repeat on the client side. I tried to create an example with a built-in method to prevent auto-repeating, but it doesn't prevent value input, although we can know if the key is auto-repeating or not. So the way to prevent auto-repeat is just like you do, call javascript code or use the JS code.
