Description:  Basically you will learn the following through this article.
  • How to upload image through asp.net fileupload control and store that image in folder?
  • How to store uploaded image path in Sql server database?
  • How to read/retrieve the image from the image path stored in database and show in Image control?
In previous related  articles i explained Upload,store image in binary format into SQL server database and retrieve using asp.net  and jQuery to validate file extension and upload image file and Maintain image on PostBack in FileUpload control and Show image preview before uploading using jQuery and Restrict user to upload images of up to specified size 

I have created a demo web page from where i will insert book record like Book name, its author, publisher, price and Book picture. Then i will retrieve that record from database and fill in the corresponding textbox and Image control.

Implementation: Let's create a demo website page to insert data including image path in database and retrieve that data and fill in corresponding controls.

First of all create a table "BookDetails" in Sql server Database with the columns and data type as shown in below:

Column Name
Data Type
BookId
Int (Primary key. Set Is Identity=true)
BookName
varchar(100)
Author
varchar(100)
Publisher
varchar(100)
Price
decimal(18, 2)
BookPicName
varchar(100)
BookPicPath
varchar(200)

Now create the following stored procedures in Sql server database
  • Stored procedure to save Book record in Database

CREATE PROCEDURE [dbo].[InsertBookDetails_Sp]
                @BookName                    VARCHAR(100),
                @Author                             VARCHAR(100),
                @Publisher                        VARCHAR(100),
                @Price                                 DECIMAL(18,2),             
                @BookPicName              VARCHAR(100)=NULL,
                @BookPicPath                VARCHAR(200)=NULL
AS
BEGIN 
                SET NOCOUNT ON;      
                INSERT INTO BookDetails(BookName,Author,Publisher,Price,BookPicName,BookPicPath)
    VALUES (@BookName,@Author,@Publisher,@Price,@BookPicName,@BookPicPath)
END

  • Stored procedure to fetch the Book record from Database

CREATE PROCEDURE [dbo].[GetBookDetails_Sp]         
AS
BEGIN 
                SET NOCOUNT ON;
                SELECT * FROM BookDetails   
END
  • In the web.config file create the connection string to connect our asp.net website to Sql server database as:

<connectionStrings>
    <add name="conStr" connectionString="Data Source=LALIT;Initial Catalog=Books_DB;Integrated Security=True"/>
  </connectionStrings>

Note: Replace the Data Source and Initial catalog as per your application

Asp.Net C# Section

Create a folder in the root directory of the project and name it "BookPictures". Uploaded Book images will be stored in this folder and then from this folder it will be converted into the binary format and then saved into the database.
  • Now In the <Head> tag of the asp.net design page(.aspx) design the page as:
<fieldset style="width:490px;">
    <legend>Save and retrieve image from database</legend>
    <table>
    <tr><td>Book Name: </td><td><asp:TextBox ID="txtBookName" runat="server"></asp:TextBox></td>
        <td rowspan="8" valign="top"><asp:Image ID="Image1" runat="server" Width="150px" Height="150px" />
           <center><asp:Label ID="lblBookPicName" runat="server" Text=""></asp:Label></center>
        </td></tr>
    <tr><td>Author: </td><td><asp:TextBox ID="txtAuthor" runat="server"></asp:TextBox></td></tr>
    <tr><td>Publisher: </td><td><asp:TextBox ID="txtPublisher" runat="server"></asp:TextBox></td></tr>
    <tr><td>Price: </td><td><asp:TextBox ID="txtPrice" runat="server"></asp:TextBox></td></tr>
    <tr><td>Book Picture: </td><td>
        <asp:FileUpload ID="flupBookPic" runat="server" /></td></tr>
        <tr><td></td><td>
            <asp:Button ID="btnSave" runat="server" Text="Save" onclick="btnSave_Click" />
            <asp:Button ID="btnCancel" runat="server" onclick="btnCancel_Click"
                Text="Cancel" />
            <asp:Button ID="btnRetrieve" runat="server" onclick="btnRetrieve_Click"
                Text="Retrieve Image" />           
            </td></tr>
        <tr><td>&nbsp;</td><td>
            <asp:Label ID="lblStatus" runat="server"></asp:Label>           
            </td></tr>
    </table>  

    </fieldset>

Asp.Net C# Code to upload Image in folder and image path in Sql server database and retrieve from Database
  • In the code behind file (.aspx.cs) write the code as:
But first of all include the required following namespaces:

using System.Data;
using System.Data.SqlClient;
using System.Configuration;
using System.IO;
using System.Drawing;

Then write the code as:

SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["conStr"].ConnectionString);

protected void btnSave_Click(object sender, EventArgs e)
    {
        string fileName = string.Empty;
        string filePath = string.Empty;
        string getPath = string.Empty;
        string pathToStore = string.Empty;
       
        SqlCommand cmd = new SqlCommand("InsertBookDetails_Sp", con);
        cmd.CommandType = CommandType.StoredProcedure;
        cmd.Parameters.AddWithValue("@BookName", txtBookName.Text.Trim());
        cmd.Parameters.AddWithValue("@Author", txtAuthor.Text.Trim());
        cmd.Parameters.AddWithValue("@Publisher", txtPublisher.Text.Trim());
        cmd.Parameters.AddWithValue("@Price", Convert.ToDecimal(txtPrice.Text));

        try
        {
            if (flupBookPic.HasFile)
            {
                fileName = flupBookPic.FileName;
                filePath = Server.MapPath("BookPictures/" + System.Guid.NewGuid() + fileName);
                flupBookPic.SaveAs(filePath); 
                cmd.Parameters.AddWithValue("@BookPicName", fileName);
                int getPos = filePath.LastIndexOf("\\");
                int len = filePath.Length;
                getPath = filePath.Substring(getPos, len - getPos);
                pathToStore = getPath.Remove(0, 1);
                cmd.Parameters.AddWithValue("@BookPicPath", pathToStore);
            }
            con.Open();
            cmd.ExecuteNonQuery();
            lblStatus.Text = "Book Record saved successfully";
            lblStatus.ForeColor = Color.Green;
            ClearControls();
        }
        catch (Exception)
        {
            lblStatus.Text = "Book Record could not be saved";
            lblStatus.ForeColor = Color.Red;
        }
        finally
        {
            con.Close();
            cmd.Dispose();
            fileName = null;
            filePath = null;           
            getPath = null;
            pathToStore = null;
        }
    }

    protected void btnRetrieve_Click(object sender, EventArgs e)
    {
        SqlDataReader dr = null;
        SqlCommand cmd = new SqlCommand("GetBookDetails_Sp", con);
        cmd.CommandType = CommandType.StoredProcedure;
        con.Open();
        try
        {
            dr = cmd.ExecuteReader();
            if (dr.HasRows)
            {
                dr.Read();
                txtBookName.Text = Convert.ToString(dr["BookName"]);
                txtAuthor.Text = Convert.ToString(dr["Author"]);
                txtPublisher.Text = Convert.ToString(dr["Publisher"]);
                txtPrice.Text = Convert.ToString(dr["Price"]);
             
                if (!string.IsNullOrEmpty(Convert.ToString(dr["BookPicPath"])))
                {
                    Image1.ImageUrl = "~/BookPictures/" + Convert.ToString(dr["BookPicPath"]);                 
lblBookPicName.Text=Convert.ToString(dr["BookPicName"]);  
                }
                lblStatus.Text = "Book record retrieved successfully";
                lblStatus.ForeColor = Color.Green;
            }
        }
        catch (Exception)
        {
            lblStatus.Text = "Book record could not be retrieved";
            lblStatus.ForeColor = Color.Red;
        }
        finally
        {
            dr.Dispose();
            con.Close();
            cmd.Dispose();
        }
    }

    protected void btnCancel_Click(object sender, EventArgs e)
    {
        ClearControls();
        lblStatus.Text = string.Empty;
        lblBookPicName.Text = string.Empty
    }

    private void ClearControls()
    {
        txtAuthor.Text = string.Empty;
        txtBookName.Text = string.Empty;
        txtPrice.Text = string.Empty;
        txtPublisher.Text = string.Empty;
        Image1.ImageUrl = null;
        txtBookName.Focus();
    }

Note: This article is just an example of the concept and it will retrieve only first records from the database. Generally we need to fetch only single record based on id e.g. BookId. So when working on the live application you can fetch the book record based on BookId by passing the BookId of the book that you want to retrieve from the database to the stored procedure "GetBookDetails_Sp" So the stored procedure will be as:

CREATE PROCEDURE [dbo].[GetBookDetails_Sp]
                @BookId            INT       
AS
BEGIN 
                SET NOCOUNT ON;
                SELECT * FROM BookDetails WHERE BookId=@BookId
END

Create a folder in the root directory of the project and name it "BookPictures". Uploaded Book images will be stored in this folder and then from this folder it will be converted into the binary format and then saved into the database.
  • In the <Head> tag of the asp.net design page(.aspx) design the page as:
