HTML’ni o‘zingiz yozish
Oldingi boblardan birida siz ma’lumotlar bazasidagi ma’lumotlarni Razor kodi yordamida, HTML belgilashini esa o‘zingiz yozib ko‘rsatgan edingiz:
Ma’lumotlar bazasi misoli
@{
var db = Database.Open("SmallBakery");
var selectQueryString = "SELECT * FROM Product ORDER BY Name";
}
<html>
<body>
<h1>Small Bakery Products</h1>
<table>
<tr>
<th>Id</th>
<th>Product</th>
<th>Description</th>
<th>Price</th>
</tr>
@foreach(var row in db.Query(selectQueryString))
{
<tr>
<td>@row.Id</td>
<td>@row.Name</td>
<td>@row.Description</td>
<td style="text-align:right">@row.Price</td>
</tr>
}
</table>
</body>
</html>

WebGrid yordamchisidan foydalanish
WebGrid yordamchisidan foydalanish — ma’lumotlarni ko‘rsatishning osonroq usuli.
WebGrid yordamchisi:
- Ma’lumotlarni ko‘rsatish uchun HTML jadvalini avtomatik tarzda tuzadi
- Formatlashning turli variantlarini qo‘llab-quvvatlaydi
- Ma’lumotlarni sahifalab ko‘rishni qo‘llab-quvvatlaydi
- Ustun sarlavhalarini bosish orqali saralashni qo‘llab-quvvatlaydi
WebGrid misoli
@{
var db = Database.Open("SmallBakery") ;
var selectQueryString = "SELECT * FROM Product ORDER BY Name";
var data = db.Query(selectQueryString);
var grid = new WebGrid(data);
}
<html>
<head>
<title>Displaying Data Using the WebGrid Helper</title>
</head>
<body>
<h1>Small Bakery Products</h1>
<div id="grid">
