How to Bind,save,edit,update,delete records from DataList in asp.net (C#,VB.Net)

Introduction: In this article i am going to explain with example How to bind, save,  edit, update, cancel and delete records/items/data from DataList in asp.net with both the C# and VB.Net language and using stored procedures and Sql server as a back end database.

Bind, save, edit, update, delete example in DataList in asp.net
Click on the image to enlarge
Description: Basically you will learn the following through this article.
  • How to perform the operations like Bind, save, edit, update, cancel and delete data from DataList data control using stored procedures and Sql server as back end database
  • How to upload image file through file upload control and show book image in DataList control.
In previous articles i explained How to Bind DataList using SqlDataAdapter and DataTable in asp.net and Bind,Save,Edit,Update,Cancel,Delete,Paging example in GridView and How to bind Repeater data control and Bind, edit, update and delete data in Repeater and Upload,download,delete image files from the GridView and create crystal reports in visual studio 2010

Implementation: Let's create an asp.net application to see the DataList's  operations in action.
  • First of all create a database in Sql server e.g.  "Book_DB" and create a table with the columns and data type as shown below and name it "Book_Tb".

Column Name
Data Type
Book_ID
Int(Primary Key. So set Is identity=true)
Title
varchar(100)
Author
varchar(100)
Publisher
varchar(100)
Price
Int
ImagePath
varchar(500)

Now we will create stored procedures to bind , save, update and delete the book records from the Sql server database table.
  • Create a stored procedure to save the Book records.
CREATE PROCEDURE SaveBookRecords_Sp
                (
                                @Title                  varchar(100),
                                @Author                             varchar(100),
                                @Publisher  varchar(100),
                                @Price     int,
                                @ImagePath     varchar(500)
                )             
AS
BEGIN
                insert into tbBook (Title,Author,Publisher,Price,ImagePath)
    values (@Title,@Author,@Publisher,@Price,@ImagePath)
END

  • Create a stored procedure to fetch the Book records and bind in DataList
CREATE PROCEDURE BindBookRecords_Sp
AS
BEGIN
                select * from tbBook
END

  • Create a stored procedure to update the book records.
CREATE PROCEDURE UpdateBookRecords_Sp
                (
                                @Book_ID          int,
                                @Title                  varchar(100),
                                @Author                             varchar(100),
                                @Publisher  varchar(100),
                                @Price     int                     
                )             
AS
BEGIN
                update tbBook set Title=@Title,Author=@Author,Publisher=@Publisher,Price=@Price
    where Book_ID=@Book_ID
END

  • Create a stored procedure to delete the book records. 
CREATE PROCEDURE DeleteBookRecords_Sp
                (
                                @Book_ID          int
                )             
AS
BEGIN
                delete from tbBook where Book_Id=@Book_ID
END
  • Now in the web.config file create the connection string to connect the asp.net application with the Sql server database.
<connectionStrings>
    <add name="conStr" connectionString="Data Source=Lalit;Initial Catalog=Book_DB;Integrated Security=True"/>
  </connectionStrings>

Note: Replace the Data Source and Initial catalog (i.e. Database name) as per your application.


  • Now in the <Body> tag of the design page e.g. default.aspx, design the page as shown below:
Source Code:

<fieldset style="width:550px">
    <legend>Bind,Save,Edit,Update,Delete in DataList</legend>  
    <table style="width:100%">
    <tr><td width="25%">Title</td><td>
        <asp:TextBox ID="txtTitle" 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>Upload Image</td><td>
            <asp:FileUpload ID="FileUpload1" runat="server" /></td></tr>
    <tr><td></td>
       <td> <asp:Button ID="btnSubmit" runat="server" Text="Save"
            onclick="btnSubmit_Click" /></td></tr>
    </table>
   
        <asp:DataList ID="dtlBooks" runat="server" RepeatColumns="2"
            oncancelcommand="dtlBooks_CancelCommand" oneditcommand="dtlBooks_EditCommand"
            onupdatecommand="dtlBooks_UpdateCommand"   ondeletecommand="dtlBooks_DeleteCommand" DataKeyField="Book_ID"
            BackColor="White" BorderColor="#3366CC" BorderStyle="None" BorderWidth="1px"
            CellPadding="4" GridLines="Both">
            <FooterStyle BackColor="#99CCCC" ForeColor="#003399" />
            <HeaderStyle BackColor="#003399" Font-Bold="True" ForeColor="#CCCCFF" />
            <ItemStyle BackColor="White" ForeColor="#003399" />
        <ItemTemplate>
        <table>
        <tr>
        <td><img src='<%#Eval("ImagePath") %>' width="90px" height="90px" alt="Book Image" /></td><td><b>Title : </b><%#Eval("Title") %><br />
        <b>Author : </b><%#Eval("Author") %><br />
        <b>Publisher : </b><%#Eval("Publisher") %><br />
        <b>Price : </b><%#Eval("Price") %><br /></td>
        </tr>
        </table>
        <asp:LinkButton ID="lnkEdit" runat="server" Text="Edit" CommandName="Edit"></asp:LinkButton>
        <asp:LinkButton ID="lnkDelete" runat="server" Text="Delete" CommandName="Delete" OnClientClick="return confirm('Are you sure you want to delete selected records')"></asp:LinkButton>
        </ItemTemplate>
        <EditItemTemplate>       
        <b>Title : </b><asp:TextBox id="txtEditTitle" runat="server" Text='<%#Eval("Title") %>'></asp:TextBox><br />
        <b>Author : </b><asp:TextBox id="txtEditAuthor" runat="server" Text='<%#Eval("Author") %>'></asp:TextBox><br />
        <b>Publisher : </b><asp:TextBox id="txtEditPublisher" runat="server" Text='<%#Eval("Publisher") %>'></asp:TextBox><br />
        <b>Price : </b><asp:TextBox id="txtEditPrice" runat="server" Text='<%#Eval("Price") %>'></asp:TextBox><br />
         <asp:LinkButton ID="lnkUpdate" runat="server" Text="Update" CommandName="Update"></asp:LinkButton>
        <asp:LinkButton ID="lnkCancel" runat="server" Text="Cancel" CommandName="Cancel"></asp:LinkButton>     
        </EditItemTemplate>
            <SelectedItemStyle BackColor="#009999" Font-Bold="True" ForeColor="#CCFF99" />
        </asp:DataList>   
         </fieldset>

Note: Create a folder in the root directory of the project and name it " BookImages" to store and fetch the book images

C#.NET Code to Bind,save,edit,update,delete records from DataList:
  • In the code behind file (.aspx.cs) write the code as:
First include the following required namespaces and write the code:

VB.NET Code to Bind,save,edit,update,delete records from DataList:
  • Design the page as shown in Source code section above but replace the line <asp:Button ID="btnSubmit" runat="server" Text="Save" onclick="btnSubmit_Click" />
with the <asp:Button ID="btnSubmit" runat="server" Text="Save" /> and also remove the oncancelcommand="dtlBooks_CancelCommand" oneditcommand="dtlBooks_EditCommand"   onupdatecommand="dtlBooks_UpdateCommand"   ondeletecommand="dtlBooks_DeleteCommand" from the DataList Source code.
  • Then in the code behind file ( .aspx.vb) write the code as:
First import the following required namespaces:
