Bind,Save,Edit,Update,Cancel,Delete and paging example in DetailsView in asp.net(C#,VB.Net)

Introduction: In this article i am going to explain with example How to perform Bind, Insert, Edit, Update, Cancel , Delete and paging operation in DetailsView in asp.net using both C# and Vb.Net language and using Stored procedure and Sql Server as a back end database.

DescriptionDetailsView is a data control that displays the values of a single record from a data source in a table, where each data row represents a field of the record. It allows us to perform the operations like insert, edit, update and delete records.

In previous articles i explained How to Bind,Save,Edit,Update,Cancel,Delete,Paging example in GridView and Bind,save,edit,update,delete records from DataList and Bind, edit, update and delete data in Repeater and Custom paging in Repeater and WCF Service to bind,insert,edit,update,delete from sql server database and Searching records in gridview .

Bind,save,edit,update,cancel,delete and paging example in detailsview in asp.net

Implementation: Let's create an asp.net sample website to see the DetailsView operations in action.

  • First of all we need to create database in sql server e.g. "dbEmp" and in this database create a table with the Columns and Data type as shown in image below and name it "Emp_Tb"

Column Name
Data Type
Emp_Id
Int(Primary Key. So set Is Identity=True)
EmpName
varchar(100)
Age
int
Salary
decimal(10, 2)
City
varchar(100)
Address
varchar(500)

  • Create a Stored procedure to Bind data in DetailsView as:

CREATE PROCEDURE BindEmpGrid_Sp            
AS
BEGIN
                SELECT * FROM Emp_Tb
END
  • Create a stored procedure to Insert employee data

CREATE PROCEDURE InsertEmpRecord_Sp
                (
                                @ename                  varchar(100),
                                @age                     int,
                                @addr                  varchar                (500),
                                @sal                      decimal(10,2)
                )             
AS
                INSERT INTO Emp_Tb(EmpName,Age,Address,Salary)VALUES(@ename,@age,@addr,@sal)

  • Create a stored procedure to update employee data

CREATE PROCEDURE UpdateEmpRecord_Sp
                (              @empId                              int,
                                @ename                  varchar(100),
                                @age                     int,
                                @addr                  varchar                (500),
                                @sal                      decimal(10,2)
                )             
AS
                UPDATE Emp_Tb SET EmpName=@ename,Age=@age,Address=@addr,Salary=@sal WHERE Emp_Id=@empId

  • Create a stored procedure to delete employee data

CREATE PROCEDURE DeleteEmpRecord_Sp
                @EmpId INT
AS
BEGIN
                DELETE FROM Emp_Tb WHERE Emp_Id=@EmpId
END

  • Now In the web.config file create the connection string as:

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

Note: Replace the Data Source and Initial Catalog (i.e. Database name) as per your application.
In the design page (.aspx) place a DetailsView data control from the visual studio's toolbox and configure it as shown below:

Private Sub detailsView1_DataBound(ByVal Sender As Object, ByVal e As System.EventArgs) Handles DetailsView1.DataBound

If Not Session("RoleID") = 1 Or Session("RoleID") = 2 Then
DetailsView1.AutoGenerateEditButton = False
Else
DetailsView1.AutoGenerateEditButton = True
End If
End Sub
