In this article I will explain with an example, how to execute Stored Procedure and get results from SQL Server Database in ASP.Net using C# and VB.Net.
 
 

Database

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

I have already inserted few records in the table.

Stored Procedure

The following Stored Procedure is used to display the records from SQL Server database.
CREATE PROCEDURE [Customers_GetCustomers]
AS
BEGIN
    SET NOCOUNT ON;
    SELECT [CustomerId]
          ,[Name]
          ,[Country]
    FROM [Customers]
END
 
 

HTML Markup

The HTML Markup consists of following control:
GridView – For displaying data.
The GridView consists of three BoundFIeld columns.
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false">
    <Columns>
        <asp:BoundField DataField="CustomerId" HeaderText="Customer Id" />
        <asp:BoundField DataField="Name" HeaderText="Name" />
        <asp:BoundField DataField="Country" HeaderText="Country" />
    </Columns>
</asp:GridView> 
 
 

Namespaces

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

Executing Stored Procedure in C# and VB.Net

Inside the Page_Load event handler, 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 or Write Connection Strings in Web.Config file using ASP.Net using C# and VB.Net.
 
Then, a connection to the database is established using SqlConnection class and CommandType is specified as Stored Procedure using SqlCommand class object.
The SqlDataAdapter object is initialized and using the Fill function, the DataTable is populated with the records from the database.
Note: For more details on SqlDataAdapter, please refer SqlDataAdapter Tutorial with example in C# and VB.Net.
 
Finally, the DataTable is assigned to the GridView and the GridView is populated with records.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
        string spName = "Customers_GetCustomers";
        using (SqlConnection con = new SqlConnection(constr))
        {
            using (SqlCommand cmd = new SqlCommand(spName, con))
            {
                cmd.CommandType = CommandType.StoredProcedure;
                using (SqlDataAdapter sda = new SqlDataAdapter(cmd))
                {
                    using (DataTable dt = new DataTable())
                    {
                        sda.Fill(dt);
                        gvCustomers.DataSource = dt;
                        gvCustomers.DataBind();
                    }
                }
            }
        }
    }
}
 
VB.Net
Protected Sub Page_Load(sender As Object, e As EventArgs) Handles Me.Load
    If Not Me.IsPostBack Then
        Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
        Dim spName As String = "Customers_GetCustomers"
        Using con As New SqlConnection(constr)
            Using cmd As New SqlCommand(spName, con)
                cmd.CommandType = CommandType.StoredProcedure
                Using sda As New SqlDataAdapter(cmd)
                    Using dt As New DataTable()
                        sda.Fill(dt)
                        gvCustomers.DataSource = dt
                        gvCustomers.DataBind()
                    End Using
                End Using
            End Using
        End Using
    End If
End Sub
