Blazor WebAssembly: Button onclick event (async methods)
We use a Blazor WebAssembly application to implement the button onclick event.
Within our Blazor Wasm app, we will create a button, and set up an onclick event by generating a call method. This will be beneficial if your onclick event is not working.
In-addition, we will demonstrate using a parameter to set up an onclick event in a child Razor component. By setting up a EventCallback type property and using the parameter attribute, we can pass an onclick event to another Razor component.
Afterwards, we will look at other Blazor events, such as onmouseover and onmouseout.
Finally, we will explore asynchronous methods. Blazor Wasm's async methods work by calling the async keyword, returning a Task type and using the await keyword to wait for a response before continuing with the method. This allows us to use the onclick event using async.
