(Dynamic Bootstrap Vertical Tabs) – Trong các bài viết trước, thủ thuật lập trình đã giới thiệu với các bạn nhiều cách để tạo Tabs động. Ví dụ như sử dụng jQuery, AjaxControlToolkit, Bootstrap nhưng đó là cách tạo Horizontal Tabs. Hôm nay thủ thuật lập trình sẽ giới thiệu với các bạn cách để tạo Vertical Tabs. 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 DynamicTabs trong SQL Server
- B2: Tạo Bảng DynamicTabs có cấu trúc phía dưới.
| 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
