upload and save image path in database and display in gridview
Click on image to enlarge
Introduction: In this article i am going to share the code to upload the image in website root folder through file upload control and save/store the image path in Sql server database and then read/retrieve the record along with image from image path and display in GridView data control in asp.net using both C# and VB languages.

Description:  Basically you will learn the following through this article.
  • How to upload image through asp.net fileupload control in folder?
  • How to store uploaded image path in Sql server database?
  • How to read/retrieve the image from the folder by reading the image path stored in sql server database and show in GridView data control?


I have created a demo web page from where i will insert book record like Book name, its author, publisher, price and Book picture. As soon as a new record will be inserted it will get binded to the GridView control as show in the sample image shown above.

Implementation: Let's create a sample website page to insert data including image and retrieve that data and fill in Grid View data 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)

Then create the following stored procedure 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 the path will be saved into the database so that we can read the image path and get the image from the folder to display in gridview.
  • In the <Form> tag of the Asp.Net design page (Default.aspx) create the page as:

<fieldset style="width:400px;">
    <legend>Save and retrieve image from database</legend>
    <table>
    <tr><td>Book Name: </td><td><asp:TextBox ID="txtBookName" runat="server"></asp:TextBox></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" />
            </td></tr>
        <tr><td>&nbsp;</td><td>
            <asp:Label ID="lblStatus" runat="server"></asp:Label>           
            </td></tr>
       
        <tr><td colspan="2">
            <asp:GridView ID="grdBooks" runat="server" AutoGenerateColumns="false">
            <Columns>
            <asp:TemplateField>
            <ItemTemplate>
           <center>  <asp:Image ID="ImgBookPic" runat="server" Height="80px" Width="80px" /><br />
             <asp:Label ID="lblBookPicName" runat="server" Text='<%#Eval("BookPicName") %>'></asp:Label>
             </center>
            </ItemTemplate>
            </asp:TemplateField>
            <asp:BoundField DataField="BookName"  HeaderText="Book Name"  ItemStyle-HorizontalAlign="Center"/>
            <asp:BoundField DataField="Author"  HeaderText="Author" ItemStyle-HorizontalAlign="Center" />
            <asp:BoundField DataField="Publisher"  HeaderText="Publisher" ItemStyle-HorizontalAlign="Center" />
            <asp:BoundField DataField="Price"  HeaderText="Price" ItemStyle-HorizontalAlign="Center" />           
            </Columns>
            </asp:GridView>          
            </td></tr>
    </table>  
    </fieldset>
