Tạo Pill Tabs động sử dụng bootstrap trong Asp.net
(Dynamic Bootstrap Pill Tabs) – Trong các bài viết trước, thủ thuật lập trình đã giới thiệu với các bạn nhiều cách để tạo Tabs động sử dụng jQuery, AjaxControlToolkit. Hôm nay thủ thuật lập trình sẽ giới thiệu với các bạn cách để tạo tạo Tab sử dụng thư viện bootstrap. Nội dung các Tabs được hiển thị từ các Control ngoài và đường dẫn cũng như tên các Control này được lấy từ CSDL SQL Server.
- B1: Tạo CSDL SQL DynamicTabs
- B2: Tạo Bảng DynamicTabs có cấu trúc phía dưới trong CSDL SQL Server.
STT | Tên trường | Kiểu trường | Ghi chú |
1 | ItemID | Int | Trường tự tăng |
2 | TabName | nvarchar(150) | |
3 | Description | nvarchar(250) | Mô tả |
4 | ControlURL | nvarchar(250) | |
5 | ImageURL | nvarchar(250) | |
6 | SortOrder | Int | Thứ tự sắp xếp |
7 | IsVisible | bit | Ân/Hiện Tab |
- B3: Nhập dữ liệu cho bảng DynamicTabs
- B4: Tạo stored procedure trong SQL Server
CREATE procedure [dbo].[Pro_DynamicTabs_List]
@IsVisible bit
as
declare @strSQL nvarchar(1000)
declare @strWhere nvarchar(500)
declare @strOrder nvarchar (50)
set @strSQL= 'Select * from DynamicTabs'
set @strWhere =' where 1=1'
if @IsVisible=1
set @strWhere= @strWhere +' and (IsVisible=1)'
if @IsVisible=0
set @strWhere= @strWhere +' and (IsVisible=0 Or IsVisible Is Null)'
set @strOrder =' Order by SortOrder, TabName'
set @strSQL=@strSQL+@strWhere+@strOrder
print @strSQL
exec sp_executesql @strSQL
- B5: Tạo Project trong Microsoft Visual Studio 2010
Trong Visual Studio tạo 1 Class có tên: Utility và nhập đoạn Code phía dưới cho Class này.

Chú ý: Thuộc tính SiteSqlServer chính là chuỗi Connect với SQL Server trong file Web.Config
- B6: Mở file Site.Master dạng HTML và bổ xung đoạn mã phía dưới trong thẻ Head
<link rel="stylesheet" href="http://netdna.bootstrapcdn.com/bootstrap/3.3.0/css/bootstrap.min.css" />
<link rel="stylesheet" href="Styles/bootstrap.vertical-tabs.css">
<script type="text/javascript" src="https://code.jquery.com/jquery-2.1.1.min.js"></script>
<script type="text/javascript" src="http://netdna.bootstrapcdn.com/bootstrap/3.3.0/js/bootstrap.min.js"></script>
- B7: Tạo thư mục Controls, lần lượt tạo các file Tab1.ascx, Tab2.ascx, Tab3.ascx, Tab4.ascx, Tab5.ascx trong thư mục này. Mỗi file sẽ nhập nội dung để phân biệt giữa các Control với nhau.
- B8: Mở file Default.aspx dưới dạng HTML và nhập mã HTML
