ASP.NET Web Pages - The WebGrid Helper

WebGrid - One of many useful ASP.NET Web Helpers.

Doing the HTML Yourself

In a previous chapter, you displayed database data by using razor code, and doing the HTML markup yourself:

Database Example

@{
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

Using the WebGrid helper is an easier way to display data.

The WebGrid helper:

  • Automatically sets up an HTML table to display data
  • Supports different options for formatting
  • Supports paging through data
  • Supports Sorting by clicking on column headings

WebGrid Example

@{ 
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>
