Introduction
In this blog, we will discuss how to create bootstrap carousel image slider with SQL server database in asp.net.We will save image path in SQL server table and image in the images folder of our project. We will display all uploaded images in Gridview with JQuery datatable.
Step 1. Open MS SQL Server of your choice and create a database table and a stored procedure as given below or copy and paste the below script.
USE [SampleDB2]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE TABLE [dbo].[ImageSlider](
[ID] [int] IDENTITY(1,1) NOT NULL,
[ImageName] [nvarchar](50) NULL,
[ImagePath] [nvarchar](100) NULL,
CONSTRAINT [PK_ImageSlider] PRIMARY KEY CLUSTERED
(
[ID] ASC
)WITH (PAD_INDEX = OFF, STATISTICS_NORECOMPUTE = OFF, IGNORE_DUP_KEY = OFF, ALLOW_ROW_LOCKS = ON, ALLOW_PAGE_LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
create procedure [dbo].[spGetAllSliderImages]
as
begin
SELECT * FROM ImageSlider
end
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE procedure [dbo].[spGetSliderImages]
as
begin
SELECT TOP 5 * FROM ImageSlider ORDER BY ID DESC
end
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE procedure [dbo].[spInsertSliderImages]
(
@ImageName nvarchar(50),
@ImagePath nvarchar(100)
)
as
begin
insert into ImageSlider(ImageName,ImagePath)
values(@ImageName,@ImagePath)
end
GO
Step 2. Open the Visual Studio version of your choice and create a new web project with empty template and give it a meaningful name.In the created project, open webconfig file and add a database connection. Change data source and database name which you have created in your SQL server.
<connectionStrings>
<add name="DBCS" connectionString="data source=DESKTOP-K5N6EMF\SQLEXPRESS; database=SampleDB2; Integrated Security=true" providerName="System.Data.SqlClient"/>
</connectionStrings>
Step 3. Add a web form, right click on the project, add a new item, choose web form, give a meaningful name and click ok. Design the HTML as given below. Drag and drop repeater control, file upload control, button control and grid view control.
Add the following script and style links:

Step 4. Double click on upload button and write the following code given below.
Add the following namespace:
using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.IO;
