WebGrid - One of many useful ASP.NET Web Helpers
In a previous chapter, you displayed database data by using razor code, and doing the HTML markup yourself:
@{
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>
Using the WebGrid helper is an easier way to display data.
The WebGrid helper:
@{
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">
@grid.GetHtml()
</div>
</body>
</html>
| Helper | Description |
|---|---|
| WebGrid(data) | Creates a new WebGrid object using data from a query. |
| WebGrid.GetHtml() | Renders markup to display data in an HTML table. |
| WebGrid.Pager() | Renders a pager for the WebGrid object. |
