In this article I will explain how to perform select, insert, edit, update, delete in GridView using a single Stored Procedure in ASP.Net using C# and VB.Net.
This process is also known as CRUD i.e. Create, Read, Update and Delete in GridView using Stored Procedure with SQL Server database backend in ASP.Net.
 
Database
I have made use of the following table Customers with the schema as follows.
GridView CRUD:Select Insert Edit Update Delete using Single Stored Procedure in ASP.Net
I have already inserted few records in the table.

HTML Markup
The HTML Markup consists of an ASP.Net GridView with multiple event handlers assigned which will be discussed later.
The GridView has a CommandField column which will display the command buttons i.e. Edit, Update, Cancel and Delete.
Below the GridView there’s a Form which will allow us to insert data to the SQL Server database table.
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="false" DataKeyNames="CustomerId"
OnRowDataBound="OnRowDataBound" OnRowEditing="OnRowEditing" OnRowCancelingEdit="OnRowCancelingEdit"
OnRowUpdating="OnRowUpdating" OnRowDeleting="OnRowDeleting" EmptyDataText="No records has been added.">
<Columns>
    <asp:TemplateField HeaderText="Name" ItemStyle-Width="150">
        <ItemTemplate>
            <asp:Label ID="lblName" runat="server" Text='<%# Eval("Name") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="txtName" runat="server" Text='<%# Eval("Name") %>'></asp:TextBox>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:TemplateField HeaderText="Country" ItemStyle-Width="150">
        <ItemTemplate>
            <asp:Label ID="lblCountry" runat="server" Text='<%# Eval("Country") %>'></asp:Label>
        </ItemTemplate>
        <EditItemTemplate>
            <asp:TextBox ID="txtCountry" runat="server" Text='<%# Eval("Country") %>'></asp:TextBox>
        </EditItemTemplate>
    </asp:TemplateField>
    <asp:CommandField ButtonType="Link" ShowEditButton="true" ShowDeleteButton="true" ItemStyle-Width="150"/>
</Columns>
</asp:GridView>
<table border="1" cellpadding="0" cellspacing="0" style="border-collapse: collapse">
<tr>
    <td style="width: 150px">
        Name:<br />
        <asp:TextBox ID="txtName" runat="server" Width="140" />
    </td>
    <td style="width: 150px">
        Country:<br />
        <asp:TextBox ID="txtCountry" runat="server" Width="140" />
    </td>
    <td style="width: 100px">
        <asp:Button ID="btnAdd" runat="server" Text="Add" OnClick="Insert" />
    </td>
</tr>
</table>
 
 
Stored Procedure for Select, Insert, Update and Delete
The following stored procedure will be used to perform Select, Insert, Update and Delete operations on the SQL Server database table.
CREATE PROCEDURE [dbo].[Customers_CRUD]
      @Action VARCHAR(10)
      ,@CustomerId INT = NULL
      ,@Name VARCHAR(100) = NULL
      ,@Country VARCHAR(100) = NULL
AS
BEGIN
      SET NOCOUNT ON;
 
      --SELECT
    IF @Action = 'SELECT'
      BEGIN
            SELECT CustomerId, Name, Country
            FROM Customers
      END
 
      --INSERT
    IF @Action = 'INSERT'
      BEGIN
            INSERT INTO Customers(Name, Country)
            VALUES (@Name, @Country)
      END
 
      --UPDATE
    IF @Action = 'UPDATE'
      BEGIN
            UPDATE Customers
            SET Name = @Name, Country = @Country
            WHERE CustomerId = @CustomerId
      END
 
      --DELETE
    IF @Action = 'DELETE'
      BEGIN
            DELETE FROM Customers
            WHERE CustomerId = @CustomerId
      END
END
 
 
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
 
 
Binding the GridView with records from SQL Database Table
The GridView is populated from the database inside the Page Load event of the page. Here the stored procedure is being called with the Action parameter value as “SELECT”.
C#
protected void Page_Load(object sender, EventArgs e)
{
    if (!this.IsPostBack)
    {
        this.BindGrid();
    }
}
 
private void BindGrid()
{
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("Customers_CRUD"))
        {
            cmd.Parameters.AddWithValue("@Action", "SELECT");
            using (SqlDataAdapter sda = new SqlDataAdapter())
            {
                cmd.CommandType = CommandType.StoredProcedure;
                cmd.Connection = con;
                sda.SelectCommand = cmd;
                using (DataTable dt = new DataTable())
                {
                    sda.Fill(dt);
                    GridView1.DataSource = dt;
                    GridView1.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 constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand("Customers_CRUD")
            cmd.Parameters.AddWithValue("@Action", "SELECT")
            Using sda As New SqlDataAdapter()
                cmd.CommandType = CommandType.StoredProcedure
                cmd.Connection = con
                sda.SelectCommand = cmd
                Using dt As New DataTable()
                    sda.Fill(dt)
                    GridView1.DataSource = dt
                    GridView1.DataBind()
                End Using
            End Using
        End Using
    End Using
End Sub
 
Following is the GridView containing records.
GridView CRUD:Select Insert Edit Update Delete using Single Stored Procedure in ASP.Net
 
For the GridView I have set EmptyDataText to display message when no records are present.

Inserting records to GridView
The following event handler is executed when the Add Button is clicked. The name and the country values are fetched from their respective TextBoxes and then passed to the Stored Procedure with Action parameter value as “INSERT”.
Finally the GridView is again populated with data by making call to the BindGrid method.
C#
protected void Insert(object sender, EventArgs e)
{
    string name = txtName.Text;
    string country = txtCountry.Text;
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("Customers_CRUD"))
        {
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Action", "INSERT");
            cmd.Parameters.AddWithValue("@Name", name);
            cmd.Parameters.AddWithValue("@Country", country);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    this.BindGrid();
}
 
VB.Net
Protected Sub Insert(sender As Object, e As EventArgs)
    Dim name As String = txtName.Text
    Dim country As String = txtCountry.Text
    Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand("Customers_CRUD")
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("@Action", "INSERT")
            cmd.Parameters.AddWithValue("@Name", name)
            cmd.Parameters.AddWithValue("@Country", country)
            cmd.Connection = con
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
        End Using
    End Using
    Me.BindGrid()
End Sub
 
 
Editing and Updating GridView records
Edit
When the Edit Button is clicked, the GridView’s OnRowEditing event handler is triggered. Here simply the EditIndex of the GridView is updated with the Row Index of the GridView Row to be edited.
C#
protected void OnRowEditing(object sender, GridViewEditEventArgs e)
{
    GridView1.EditIndex = e.NewEditIndex;
    this.BindGrid();
}
 
VB.Net
Protected Sub OnRowEditing(sender As Object, e As GridViewEditEventArgs)
    GridView1.EditIndex = e.NewEditIndex
    Me.BindGrid()
End Sub
 
Update
When the Update Button is clicked, the GridView’s OnRowUpdating event handler is triggered.
CustomerId which is the primary key is fetched from the DataKey property of GridView while the Name and Country fields are fetched from their respective TextBoxes and are passed to the Stored Procedure with Action parameter value as “UPDATE”.
For more details on DataKeys please refer my article DataKeyNames in GridView example in ASP.Net.
C#
protected void OnRowUpdating(object sender, GridViewUpdateEventArgs e)
{
    GridViewRow row = GridView1.Rows[e.RowIndex];
    int customerId = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values[0]);
    string name = (row.FindControl("txtName") as TextBox).Text;
    string country = (row.FindControl("txtCountry") as TextBox).Text;
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("Customers_CRUD"))
        {
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Action", "UPDATE");
            cmd.Parameters.AddWithValue("@CustomerId", customerId);
            cmd.Parameters.AddWithValue("@Name", name);
            cmd.Parameters.AddWithValue("@Country", country);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    GridView1.EditIndex = -1;
    this.BindGrid();
}
 
VB.Net
Protected Sub OnRowUpdating(sender As Object, e As GridViewUpdateEventArgs)
    Dim row As GridViewRow = GridView1.Rows(e.RowIndex)
    Dim customerId As Integer = Convert.ToInt32(GridView1.DataKeys(e.RowIndex).Values(0))
    Dim name As String = TryCast(row.FindControl("txtName"), TextBox).Text
    Dim country As String = TryCast(row.FindControl("txtCountry"), TextBox).Text
    Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand("Customers_CRUD")
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("@Action", "UPDATE")
            cmd.Parameters.AddWithValue("@CustomerId", customerId)
            cmd.Parameters.AddWithValue("@Name", name)
            cmd.Parameters.AddWithValue("@Country", country)
            cmd.Connection = con
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
        End Using
    End Using
    GridView1.EditIndex = -1
    Me.BindGrid()
End Sub
 
Cancel Edit
When the Cancel Button is clicked, the GridView’s OnRowCancelingEdit event handler is triggered. Here the EditIndex is set to -1 and the GridView is populated with data.
C#
protected void OnRowCancelingEdit(object sender, EventArgs e)
{
    GridView1.EditIndex = -1;
    this.BindGrid();
}
 
VB.Net
Protected Sub OnRowCancelingEdit(sender As Object, e As EventArgs)
    GridView1.EditIndex = -1
    Me.BindGrid()
End Sub

Deleting GridView records
When the Delete Button is clicked, the GridView’s OnRowDeleting event handler is triggered.
CustomerId which is the primary key is fetched from the DataKey property of GridView and is passed to the Stored Procedure along with the Action parameter value as “DELETE”.
C#
protected void OnRowDeleting(object sender, GridViewDeleteEventArgs e)
{
    int customerId = Convert.ToInt32(GridView1.DataKeys[e.RowIndex].Values[0]);
    string constr = ConfigurationManager.ConnectionStrings["constr"].ConnectionString;
    using (SqlConnection con = new SqlConnection(constr))
    {
        using (SqlCommand cmd = new SqlCommand("Customers_CRUD"))
        {
            cmd.CommandType = CommandType.StoredProcedure;
            cmd.Parameters.AddWithValue("@Action", "DELETE");
            cmd.Parameters.AddWithValue("@CustomerId", customerId);
            cmd.Connection = con;
            con.Open();
            cmd.ExecuteNonQuery();
            con.Close();
        }
    }
    this.BindGrid();
}
 
VB.Net
Protected Sub OnRowDeleting(sender As Object, e As GridViewDeleteEventArgs)
    Dim customerId As Integer = Convert.ToInt32(GridView1.DataKeys(e.RowIndex).Values(0))
    Dim constr As String = ConfigurationManager.ConnectionStrings("constr").ConnectionString
    Using con As New SqlConnection(constr)
        Using cmd As New SqlCommand("Customers_CRUD")
            cmd.CommandType = CommandType.StoredProcedure
            cmd.Parameters.AddWithValue("@Action", "DELETE")
            cmd.Parameters.AddWithValue("@CustomerId", customerId)
            cmd.Connection = con
            con.Open()
            cmd.ExecuteNonQuery()
            con.Close()
        End Using
    End Using
    Me.BindGrid()
End Sub
 
In order to display a confirmation message when deleting row, I have made use of OnRowDataBound event handler where I have first determined the Delete Button and then I have attach the JavaScript Confirm to its client side Click event handler.
C#
protected void OnRowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.RowType == DataControlRowType.DataRow && e.Row.RowIndex != GridView1.EditIndex)
    {
        (e.Row.Cells[2].Controls[2] as LinkButton).Attributes["onclick"] = "return confirm('Do you want to delete this row?');";
    }
}
 
VB.Net
Protected Sub OnRowDataBound(sender As Object, e As GridViewRowEventArgs)
    If e.Row.RowType = DataControlRowType.DataRow AndAlso e.Row.RowIndex <> GridView1.EditIndex Then
        TryCast(e.Row.Cells(2).Controls(2), LinkButton).Attributes("onclick") = "return confirm('Do you want to delete this row?');"
    End If
End Sub
