Upload image in folder and path in Sql server database and retrieve and bind to DataList control in Asp.Net C#,VB

Introduction: In this article i am going to share the code to upload the image through file upload control and save/store the image in website root folder and store the image path in Sql server database and then read/retrieve the record along with image from image path and display in DataList 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 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 DataList 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 is inserted, it will get binded to the Datalist control as show in the sample image shown above.

Implementation: Let's create a demo website page to insert data including image path in database and retrieve that data and fill in datalist 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.
    • In the <Form> tag of the Asp.Net design page(Default.aspx) create 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>
            </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>&nbsp;</td><td>
                &nbsp;</td></tr>
            <tr><td colspan="2">
                <asp:DataList ID="dlBooks" runat="server" RepeatColumns="2" RepeatDirection="Horizontal" >
                <ItemTemplate>
                <table>
                <tr style="border:1 solid #888;">
                <td>
                <asp:Image ID="ImgBookPic" runat="server" Height="80px" Width="80px" /><br />
                <asp:Label ID="lblBookPicName" runat="server" Text='<%#Eval("BookPicName") %>'></asp:Label>
                </td>
                <td valign="top">
                <asp:Label ID="lblBookName" runat="server" Text='<%#Eval("BookName") %>'></asp:Label><br />
                <asp:Label ID="lblAuthor" runat="server" Text='<%#Eval("Author") %>'></asp:Label><br />
                <asp:Label ID="lblPublisher" runat="server" Text='<%#Eval("Publisher") %>'></asp:Label><br />
                <asp:Label ID="lblPrice" runat="server" Text='<%#Eval("Price") %>'></asp:Label>
                </td>
                </tr>
                </table>
                </ItemTemplate>
                </asp:DataList>
                </td></tr>
        </table>  
        </fieldset>

    Asp.Net VB Section:
    • Design the page as described in the Asp.Net C# Section above but replace the lines

    <asp:Button ID="btnCancel" runat="server" onclick="btnCancel_Click" Text="Cancel" />

    With the following lines:

    <asp:Button ID="btnSave" runat="server" Text="Save" />
    <asp:Button ID="btnCancel" runat="server" Text="Cancel" />
