In this article I will explain with an example, how to Select SQL Server Stored Procedure using ADO.Net.
 
 

Database

Here I am making use of Microsoft’s Northwind Database. The download and install instructions are provided in the following article
Download and install Northwind Database
 
 

Stored Procedure

The following Stored Procedure will be used to select data from the SQL Server database table.
CREATE PROCEDURE [Customers_GetCustomer]
AS
BEGIN
      SET NOCOUNT ON;
      SELECT CustomerId
            ,ContactName
            ,City
            ,Country
      FROM Customers
END
 
 

HTML Markup

GridView – For displaying data.

Columns

GridView consists of four BoundField columns.
The following HTML Markup consists of:
 

Properties

PageSize – For permitting maximum number of rows to be displayed per page.
AllowPaging – For enabling paging in the GridView control.
 

Events

GridView has been assigned with an event handler i.e. OnPageIndexChanging.
<asp:GridView ID="gvCustomers" runat="server" AutoGenerateColumns="false" AllowPaging="true" 
    OnPageIndexChanging="OnPageIndexChanging" PageSize="10">
    <Columns>
        <asp:BoundField DataField="CustomerID" HeaderText="Customer Id"  /> 
        <asp:BoundField DataField="ContactName" HeaderText="Contact Name" />
        <asp:BoundField DataField="City" HeaderText="City" />
        <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
 
 

Populating GridView from database

Inside the Page Load event handler, the BindGrid method is called.

BindGrid

Inside the BindGrid method, the Stored Procedure is called and the GridView is populated with records.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.BindGrid();
    }
}
 
private void BindGrid()
{
    string spName = "Customers_GetCustomers";
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand(spName))
        {
            using (SqlDataAdapter sda = new SqlDataAdapter(spName, con))
            {
                cmd.CommandType = CommandType.StoredProcedure;
                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
        Me.BindGrid()
    End If
End Sub
 
Private Sub BindGrid()
    Dim spName As String = "Customers_GetCustomers"
    Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand(spName, con)
            Using sda As New SqlDataAdapter(cmd)
                 cmd.CommandType = CommandType.StoredProcedure
                Using dt As New DataTable()
                    sda.Fill(dt)
                    gvCustomers.DataSource = dt
                    gvCustomers.DataBind()
                End Using
            End Using
        End Using
    End Using
End Sub
 
 

Implementing Paging in GridView

Inside the OnPageIndexChanging event handler, the PageIndex property of the GridView is updated with the new Page Number which was clicked.
Finally, the GridView is populated using the BindGrid method which in-turn displays the new GridView page.
C#
protected void OnPageIndexChanging(object sender, GridViewPageEventArgs e)
{
    gvCustomers.PageIndex = e.NewPageIndex;
    this.BindGrid();
}
 
VB.Net
Protected Sub OnPageIndexChanging(sender As Object, e As GridViewPageEventArgs)
    gvCustomers.PageIndex = e.NewPageIndex
    Me.BindGrid()
End Sub
