Experiment 7-10
Aim:Writea program in ASP.netfor Insertion, Deletion, Updationand
searching using ADO.net.
Source:
ADO.NET Entity Framework is an powerful tools to developed applications. This tutorial will help
you to insert, update, delete, select, search data into SQL Server by using ADO.NET Entity
Framework. For this we will use two tables Students and Countries. We will save Student ID, Name,
Address, Phone and Country of a Student in Students table. In Countries table there will be some
predefined country data. We will show the entire country list in a DropDownList and student
list in a GridView. Summary of the articles are:
 UI Design
 Database Design
Creation of Entity Data Model
 Select Operation
 Insert Operation
 Update Operation
 Delete Operation
 Search Operation
UI Design
Create a new asp.net,C# project. Design your UI. You can use the following asp.net code.
<table>
<tr> <td style=”width: 120px”> Student ID </td>
<td> <asp:TextBox ID=”txtID” runat=”server” Enabled=”False”></asp:TextBox> </td>
</tr>
<tr> <td style=”width: 120px”> Student Name</td>
<td> <asp:TextBox ID=”txtName” runat=”server” Width=”250px”></asp:TextBox> </td>
</tr>
<tr>
<td> Address </td>

<asp:BoundField DataField=”country_id” HeaderText=”Country ID” />
<asp:BoundField DataField=”country_name” HeaderText=”Country Name” />
</Columns>
</asp:GridView>

Database Design:
Create two table Students and Countries in your database. Sample scripts for both tables are given
below:
CREATE TABLE [dbo].[Students](
[StudentID] [bigint] IDENTITY(1,1) NOT NULL,
[StudentName] [nvarchar](100) NULL,
[Address] [nvarchar](150) NULL,
[Phone] [nvarchar](50) NULL,
[CountryID] [nchar](2) NOT NULL,
CONSTRAINT [PK_student] PRIMARYKEY
CLUSTERED
(
[StudentID] ASC)WITH (PAD_INDEX= OFF,STATISTICS_
NORECOMPUTE = OFF,IGNORE_DUP_KEY =
OFF, ALLOW_ROW_LOCKS = ON,ALLOW_PAGE_
LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
CREATE TABLE [dbo].[Countries](
[CountryID] [nchar](2) NOT NULL,
[CountryName] [nvarchar](150) NOT NULL,
[Nationality] [nvarchar](100) NULL,
CONSTRAINT [PK_country] PRIMARY KEY
CLUSTERED
(
[CountryID] ASC
)WITH (PAD_INDEX= OFF, STATISTICS_
NORECOMPUTE = OFF,IGNORE_DUP_KEY =

CSE/8th
OFF, ALLOW_ROW_LOCKS = ON,ALLOW_PAGE_
LOCKS = ON) ON [PRIMARY]
) ON [PRIMARY]
Select Operation
Make an object of Data Model in .cs page like this
TestDBEntities oTestDBEntities = new TestDBEntities();
Write the following code in page load event.
if (!IsPostBack)
{
Load_Country();
}
To select data form country table write the following code.
public List<Country> LoadCountry()
{
var result = from Con in oTestDBEntities.Countriesselect Con;
return result.ToList();
}
To bind the country DropDownList writes the following code:
public void Load_Country()
{
ddlCountry.DataSource = LoadCountry();
ddlCountry.DataTextField = “CountryName”;
ddlCountry.DataValueField = “CountryID”;
ddlCountry.DataBind();
}

CSE/8th
To select data form students table write the following code.
public IList<object> LoadStudent()
{
var result = from std in oTestDBEntities.Students join Con in
oTestDBEntities.Countries on
std.CountryID equals Con.CountryID select new { std.StudentID, std.StudentName,
std.Address,std.Phone, std.CountryID, Con.CountryName };
IList<Object> items = new List<Object>();
foreach (var per in result)
{
items.Add(per);
}
return items;
}
To bind the student GridView writes the following code:
public void Load_Student()
{
GridView1.DataSource = LoadStudent();
GridView1.DataBind();
}
Call Load_Student() function in page load event.
Write the following code to show data of selected students in UI.
protected void GridView1_SelectedIndexChanged(object sender, EventArgs e)
{
GridViewRow row = GridView1.SelectedRow;

CSE/8th
txtID.Text = row.Cells[1].Text;
txtName.Text = row.Cells[2].Text;
txtAddress.Text = row.Cells[3].Text;
txtPhone.Text = row.Cells[4].Text;
ddlCountry.Text = row.Cells[5].Text;
}
Insert Operation
To insert or save data in to database write the following code.
oStudent.StudentName = txtName.Text;
oStudent.Phone = txtPhone.Text;
oStudent.Address = txtAddress.Text;
oStudent.CountryID =
ddlCountry.SelectedValue.ToString();
InsertData(oStudent);
Load_Student();
public void InsertData(Student oStudent)
{
oTestDBEntities.Students.AddObject(oStudent);
oTestDBEntities.SaveChanges();
}
Update Operation
To update the record of a student write the following code.
oStudent.StudentID = Convert.ToInt16(txtID.Text) ;
oStudent.StudentName = txtName.Text;
oStudent.Phone = txtPhone.Text;

CSE/8th
oStudent.Address = txtAddress.Text;
oStudent.CountryID = ddlCountry.SelectedValue.ToString();
UpdateData(oStudent);
Load_Student();
public void UpdateData(Student oStudent)
{
var result = (from st in oTestDBEntities.Students
where st.StudentID == oStudent.StudentID
select st).Single();
result.StudentName = oStudent.StudentName;
result.Address = oStudent.Address;
result.Phone = oStudent.Phone;
result.CountryID = oStudent.CountryID;
oTestDBEntities.Students.ApplyCurrentValues
(result);
}
Delete Operation:
To delete data from the database write the following code.
oStudent.StudentID = Convert.ToInt16(txtID.Text) ;
DeleteData(oStudent);
Load_Student();
public void DeleteData(Student oStudent)
{
var result = (from st in oTestDBEntities.Students
where st.StudentID == oStudent.StudentID
select st).Single();

CSE/8th
oTestDBEntities.Students.DeleteObject(result);
}
Search Operation
oStudent.StudentID = Convert.ToInt 16(txtSearch.Text);
GridView1.DataSource = SearchStudent (oStudent);
GridView1.DataBind();
public IList<object> SearchStudent(Student oStudent)
{
IList<Object> items = new List<Object>();
var result = from std in oTestDBEntities.Students join Con in oTestDBEntities.Countries on
std.CountryID equals Con.CountryID where std.StudentID == oStudent.StudentID select new
{ std.StudentID, std.StudentName, std.Address,std.Phone, std.CountryID,
Con.CountryName };
foreach (var per in result)
{
items.Add(per);
}
return items;
ON
