问题 Using the example from the Microsoft docs, I'm trying to programmatically set the focus to an input element. Unfortunately, the example uses a standard <input type="text"> whereas I want to use it for an InputText element. The Microsoft example uses an extensions method that takes an ElementReference : public static Task Focus(this ElementReference elementRef, IJSRuntime jsRuntime) { return jsRuntime.InvokeAsync<object>( "exampleJsFunctions.focusElement", elementRef); } Using an InputText , I

问题 How can I restrict TModel to be classes only or to be implementing a specifix interface? @typeparam TModel cannot get the syntax working. 回答1: The solution is to additionally put the type constraint in a partial code behind class.

问题 I am using Blazorise, which provide multiple base components such as <Button> , with multiple parameters. I would like to create a simple component which would render a <Button> with one or two parameters hard-coded (such as Color="Colors.Primary") and then pass the rest of the parameters onto the <Button> . This is what I would like to be able to write: <PrimaryButton Outline>Text</Button> I would like to achieve this without having to manually set all parameters available from <Button> in
