## 📌 Notes

|
||||
|
||||
### Part 1: Introduction to Views
|
||||
|
||||
- Views (.cshtml files) are templates that render HTML with Razor syntax.
|
||||
- Views are organized in `Views/ControllerName/ViewName.cshtml`.
|
||||
- The `View()` method in a controller renders the corresponding view.
|
||||
- Layouts (\_Layout.cshtml) allow reuse of common HTML structure like headers/footers.
|
||||
- Partial Views help modularize repeated sections (like a profile box).
|
||||
|
||||
### Part 2: Razor Syntax
|
||||
|
||||
- Use `@` to enter C# in HTML.
|
||||
- Implicit: `@Model.Name`, Explicit: `@(Model.Name + "!")`
|
||||
- Code blocks: `@{ var msg = "Hello"; }`
|
||||
- Loops and conditionals are supported: `@if`, `@for`, `@foreach`, `@switch`
|
||||
- Razor supports local functions in code blocks for reusability
|
||||
|
||||
### Part 3: Bootstrap
|
||||
|
||||
- Bootstrap helps in building responsive UI components.
|
||||
- Grid system, forms, buttons, navbars, modals etc. are supported.
|
||||
- Integration involves adding Bootstrap CSS/JS in layout or view.
|
||||
|
||||
### Part 4: Tag Helpers and HTML Helpers
|
||||
|
||||
#### Tag Helpers:
|
||||
|
||||
- Looks like HTML with `asp-*` attributes
|
||||
- Example: `<a asp-controller="Home" asp-action="About">Link</a>`
|
||||
- Requires `@addTagHelper *, Microsoft.AspNetCore.Mvc.TagHelpers` in `_ViewImports.cshtml`
|
||||
|
||||
#### HTML Helpers:
|
||||
|
||||
- Use C# syntax like `@Html.TextBoxFor(...)`, `@Html.BeginForm()`
|
||||
- More verbose but offers fine control with C# expressions
|
||||
|
||||
#### Comparison:
|
||||
|
||||
| Feature | Tag Helpers | HTML Helpers |
|
||||
| ----------- | ----------- | ------------ |
|
||||
| Syntax | HTML-like | C# methods |
|
||||
| Readability | High | Moderate |
|
||||
| Use | `asp-*` | `@Html.*` |
|
||||
|
||||
## 🧪 Practice
|
||||
|
||||
- Create a view with a layout and partial
|
||||
- Use Razor syntax to display dynamic data
|
||||
- Build a form with Tag Helpers
|
||||
- Refactor a view using HTML Helpers
