Download a Blazor WebAssembly button onclick event example

Download the code example for a Blazor WebAssembly button onclick event example.

The Blazor Wasm application sets up a button onclick event and is activated by a call method. This is beneficial if your onclick event is not working.

It also shows how to use the [Parameter] attribute 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.

In-addition, onmouseover and onmouseout are other Blazor events that the application uses.

There is also an example for using 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.
