This data is known as <strong>state<\/strong>. In Blazor, managing state properly is important for delivering a smooth user experience. Whether it&#8217;s keeping a draft blog post, remembering a selected category, or tracking login status, state management helps your app stay consistent and responsive.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>What Is State Management?<\/strong><\/h3>\n\n\n\n<p>State is the data your app uses to behave correctly, such as a user\u2019s draft input, login status, or preferences. State management refers to how that data is stored, updated, and shared across components and pages in your Blazor application.<\/p>\n\n\n\n<p><strong>Blog State Example Using Dependency Injection<\/strong><\/p>\n\n\n\n<h4 class=\"wp-block-heading\"><strong>Step 1: Create a Blog State Service<\/strong><\/h4>\n\n\n\n<pre class=\"wp-block-code\"><code>public class BlogDraftState\n{\n    public BlogPost Draft { get; private set; } = new();\n\n    public void UpdateDraft(BlogPost updated)\n    {\n        Draft = updated;\n    }\n\n    public void Clear()\n    {\n        Draft = new BlogPost();\n    }\n}<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Register the Service in Program.cs<\/h3>\n\n\n\n<pre class=\"wp-block-code\"><code>builder.Services.AddScoped&lt;BlogDraftState>();<\/code><\/pre>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Use the State Service in CreateBlog.razor<\/h3>\n\n\n\n<pre class=\"wp-block-code\"><code>@page \"\/create-blog\"\n@inject BlogDraftState DraftState\n@inject NavigationManager Navigation\n\n&lt;h3>Create Blog Post (Draft Supported)&lt;\/h3>\n\n&lt;EditForm Model=\"@DraftState.Draft\" OnValidSubmit=\"SavePost\">\n    &lt;DataAnnotationsValidator \/>\n    &lt;ValidationSummary \/>\n\n    &lt;div class=\"mb-3\">\n        &lt;label>Title&lt;\/label>\n        &lt;InputText class=\"form-control\" @bind-Value=\"DraftState.Draft.Title\" \/>\n    &lt;\/div>\n\n    &lt;div class=\"mb-3\">\n        &lt;label>Content&lt;\/label>\n        &lt;InputTextArea class=\"form-control\" @bind-Value=\"DraftState.Draft.Content\" \/>\n    &lt;\/div>\n\n    &lt;button class=\"btn btn-primary\">Publish&lt;\/button>\n&lt;\/EditForm>\n\n&lt;button class=\"btn btn-secondary mt-2\" @onclick=\"@(() => Navigation.NavigateTo(\"\/blogs\"))\">\n    Leave and Come Back\n&lt;\/button>\n\n@code {\n    void SavePost()\n    {\n        Console.WriteLine($\"Saving: {DraftState.Draft.Title}\");\n        DraftState.Clear();\n        Navigation.NavigateTo(\"\/blogs\");\n    }\n}<\/code><\/pre>\n\n\n\n<h2 class=\"wp-block-heading\">Conclusion<\/h2>\n\n\n\n<p>Blazor makes it easy to manage state using services and dependency injection. This approach helps you keep data available across pages and components, especially in multi-step workflows or draft forms. For more complex scenarios, you can combine this with tools like local storage or external state containers.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Modern web applications often need to preserve data across multiple pages or components.
