How do I set focus to a text box in Blazor

How do I set focus to a textbox in Blazor? So far the only way we have found is with JavaScript.

There is no other way to do it... You can use JSInterop to do this, as follows:

 <input type="text" @ref="myref"/>

 @code {

    private ElementReference myref;
    [Inject] IJSRuntime JSRuntime { get; set; }

     protected override async Task OnAfterRenderAsync(bool firstRender)
    {
         if (firstRender)
        {
            await 
        JSRuntime.InvokeVoidAsync("exampleJsFunctions.focusElement", myref);
        }
   }
 }

JavaScript

<script>

    window.exampleJsFunctions =
    {
        focusElement: function (element) {
           element.focus();
        }
    };
</script>

Hope this helps...
