To disable elements you should use the disabled attribute. I’ve modified your code a bit and this will do what you’re after. Blazor will automatically add or remove the disabled attribute based on the IsDisabled value. You should use the disabled attribute on your button as well. It’s a much better practice. <button type=”button” disabled=”@IsDisabled”></button> … Read more
@bind is essentially equivalent to the having both value and @onchange, e.g.: <input @bind=”CurrentValue” /> Is equivalent to: <input value=”@CurrentValue” @onchange=”@((ChangeEventArgs e) => CurrentValue = e.Value.ToString())” /> Since you’ve already defined @onchange, instead of also adding @bind, just add value to prevent the clash: <select value=”@SelectedCustID” @onchange=”@CustChanged” class=”form-control”> @foreach (KeyGuidPair i in CustList) { <option … Read more

Code creation is intended to be flexible and encourages component-based layouts, as … Read more
Use the Uri property from the NavigationManager class. How it works Get it from injection before using it on .razor pages: @inject NavigationManager MyNavigationManager Or like this in a .cs file if you prefer the “code-behind” experience: using Microsoft.AspNetCore.Components; // … [Inject] public NavigationManager MyNavigationManager {get; set;} = default!; Sample @page “/navigate” @inject NavigationManager MyNavigationManager … Read more
Try it with a lambda. You’re binding the onclick to the result of the function rather than the function itself. @for (int i = 0; i < 10; i++) { var buttonNumber = i; <button @onclick=”@(e => test(buttonNumber, 5 * buttonNumber))”>Check</button> }

Is it true that the browser will need to download the WebAssembly library every time the page loads? No, browsers can cache the files. Common CDNs for Blazor applications will do the trick. Is this system faster to work than, for example, React / Vue.js, compiled in JavaScript? Blazor uses WebAssembly, On paper WebAssembly should … Read more
