In this article I will explain with an example, how to call insert SQL Server Stored Procedure using ADO.Net in C# and VB.Net.
 
 

Database

I have made use of the following table Customers with the schema as follows.

Stored Procedure

The following Stored Procedure will be used to Insert data into the SQL Server database.
This Stored Procedure accepts Name and Country parameters, which are used to Insert the records in Customers Table.
CREATE PROCEDURE [Customers_InsertCustomer]
      @Name VARCHAR(100),
      @Country VARCHAR(50)
AS
BEGIN
    INSERT INTO [Customers]
               ([Name]
               ,[Country])
    VALUES
               (@Name
               ,@Country)
 
    SELECT SCOPE_IDENTITY()
END
 
 

HTML Markup

Inside the HTML Form the following CSS is inherited.
1. bootstrap.min.css
 
Then, the following JS scripts are inherited.
1. jquery.min.js
2. bootstrap.bundle.min.js
 
The HTML Markup consists of following controls:
HTML Button – For opening the Bootstrap Modal Popup.
div – For Bootstrap Modal Popup contents.
TextBox – For inputting Name.
DropDownList – For selecting Country.
Button – For submitting the Form.
The Button has been assigned with an OnClick event handler.

Namespaces

You will need to import the following namespaces.
C#
using System.Data;
using System.Configuration;
using System.Data.SqlClient;
 
VB.Net
Imports System.Data
Imports System.Configuration
Imports System.Data.SqlClient
 
 

Inserting record in Database using Stored Procedure in ASP.Net

When the Save changes button is clicked, first the connection is read from Web.Config file.
Note: For more details on how to read connection string from Web.Config file, please refer my article Read (Get) Connection String from Web.Config file in ASP.Net using C# and VB.Net.
 
The values of Name and Country are added as parameter to SqlCommand object.
Then, using ExecuteScalar method, the record is inserted into the SQL Server database using Stored Procedure.
Note: For more details on how to use ExecuteScalar method, please refer my article Understanding SqlCommand ExecuteScalar in C# and VB.Net.
 
Finally, the CustomerId of the inserted record is fetched and displayed in JavaScript Alert Message Box using RegisterStartupScript method.
C#
protected void OnInsert(object sender, EventArgs e)
{
    int customerId;
    string spName = "Customers_InsertCustomer";
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand(spName, con))
        {
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Name", txtName.Text);
            cmd.Parameters.AddWithValue("@Country", ddlCountries.SelectedItem.Text);
            con.Open();
            customerId = Convert.ToInt32(cmd.ExecuteScalar());
            con.Close();
        }
    }
    ClientScript.RegisterStartupScript(this.GetType(), "alert", "alert('Inserted Customer ID: " + customerId + "');", true);
}
 
VB.Net
Protected Sub OnInsert(ByVal sender As Object, ByVal e As EventArgs)
    Dim customerId As Integer
    Dim spName As String = "Customers_InsertCustomer"
    Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As SqlConnection = New SqlConnection(constr)
        Using cmd As SqlCommand = New SqlCommand(spName, con)
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("@Name", txtName.Text)
            cmd.Parameters.AddWithValue("@Country", ddlCountries.SelectedItem.Text)
            con.Open()
            customerId = Convert.ToInt32(cmd.ExecuteScalar())
            con.Close()
        End Using
    End Using
    ClientScript.RegisterStartupScript(Me.GetType(), "alert", "alert('Inserted Customer ID: " & customerId & "');", True)
End Sub
