Before implement this example first design one table productinfo in your database as shown below
Column Name
|
Data Type
|
Allow Nulls
|
productid
|
Int(IDENTITY=TRUE)
|
Yes
|
productname
|
varchar(50)
|
Yes
|
price
|
varchar(50)
|
Yes
|
Now create one new stored procedure “Crudoperations” in your sql server database to perform insert, select, update and delete operations with single procedure for that follow below script
CREATE PROCEDURE CrudOperations
@productid int = 0,
@productname varchar(50)=null,
@price int=0,
@status varchar(50)
AS
BEGIN
SET NOCOUNT ON;
--- Insert New Records
IF @status='INSERT'
BEGIN
INSERT INTO productinfo1(productname,price) VALUES(@productname,@price)
END
--- Select Records in Table
IF @status='SELECT'
BEGIN
SELECT productid,productname,price FROM productinfo1
END
--- Update Records in Table
IF @status='UPDATE'
BEGIN
UPDATE productinfo1 SET productname=@productname,price=@price WHERE productid=@productid
END
--- Delete Records from Table
IF @status='DELETE'
BEGIN
DELETE FROM productinfo1 where productid=@productid
END
SET NOCOUNT OFF
END

In case if you have any doubts to create procedure check below article
Once we finish stored procedure creation in database now open your aspx page and write the code like as shown below
<html xmlns="http://www.w3.org/1999/xhtml">
<head id="Head1" runat="server">
<title>GridView Crud (Select Insert Edit Update Delete) Operations using Single Stored Procedure in ASP.Net</title>
<style type="text/css">
.GridviewDiv {font-size: 100%; font-family: 'Lucida Grande', 'Lucida Sans Unicode', Verdana, Arial,Helevetica, sans-serif; color: #303933;}
.headerstyle
{
color:#FFFFFF;border-right-color:#abb079;border-bottom-color:#abb079;background-color:#df5015;padding:0.5em 0.5em 0.5em 0.5em;text-align:center;
}
</style>
</head>
<body>
<form id="form1" runat="server">
<div class="GridviewDiv">
<asp:GridView runat="server" ID="gvDetails" ShowFooter="true" AllowPaging="true" PageSize="10"AutoGenerateColumns="false" DataKeyNames="productid,productname"OnPageIndexChanging="gvDetails_PageIndexChanging"OnRowCancelingEdit="gvDetails_RowCancelingEdit"
OnRowEditing="gvDetails_RowEditing" OnRowUpdating="gvDetails_RowUpdating"OnRowDeleting="gvDetails_RowDeleting" OnRowCommand ="gvDetails_RowCommand" >
<HeaderStyle CssClass="headerstyle" />
<Columns>
<asp:BoundField DataField="productid" HeaderText="Product Id" ReadOnly="true" />
<asp:TemplateField HeaderText="Product Name">
<ItemTemplate>
<asp:Label ID="lblProductname" runat="server" Text='<%# Eval("productname")%>'/>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtProductname" runat="server" Text='<%# Eval("productname")%>'/>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtpname" runat="server" />
</FooterTemplate>
</asp:TemplateField>
<asp:TemplateField HeaderText = "Price">
<ItemTemplate>
<asp:Label ID="lblPrice" runat="server" Text='<%# Eval("price")%>'></asp:Label>
</ItemTemplate>
<EditItemTemplate>
<asp:TextBox ID="txtProductprice" runat="server" Text='<%# Eval("price")%>'/>
</EditItemTemplate>
<FooterTemplate>
<asp:TextBox ID="txtprice" runat="server" />
<asp:Button ID="btnAdd" CommandName="AddNew" runat="server" Text="Add" />
</FooterTemplate>
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" ShowDeleteButton="true" />
</Columns>
</asp:GridView>
<asp:Label ID="lblresult" runat="server"></asp:Label>
</div>
</form>
</body>
</html>

After completion of aspx page add following namespaces in codebehind
C# Code
using System;
using System.Web.UI.WebControls;
using System.Data.SqlClient;
using System.Data;
using System.Drawing;
|
After completion of adding namespaces you need to write the code like as shown below
protected void Page_Load(object sender, EventArgs e)
{
if (!IsPostBack)
{
BindGridview();
}
}
protected void BindGridview()
{
DataSet ds = new DataSet();
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("crudoperations", con);
cmd.CommandType= CommandType.StoredProcedure;
cmd.Parameters.AddWithValue("@status","SELECT");
SqlDataAdapter da = new SqlDataAdapter(cmd);
da.Fill(ds);
con.Close();
if (ds.Tables[0].Rows.Count > 0)
{
gvDetails.DataSource = ds;
gvDetails.DataBind();
}
else {
ds.Tables[0].Rows.Add(ds.Tables[0].NewRow());
gvDetails.DataSource = ds;
gvDetails.DataBind();
int columncount = gvDetails.Rows[0].Cells.Count;
gvDetails.Rows[0].Cells.Clear();
gvDetails.Rows[0].Cells.Add(new TableCell());
gvDetails.Rows[0].Cells[0].ColumnSpan = columncount;
gvDetails.Rows[0].Cells[0].Text = "No Records Found";
}
}
}
protected void gvDetails_RowCommand(object sender, GridViewCommandEventArgs e)
{
if (e.CommandName.Equals("AddNew"))
{
TextBox txtname = (TextBox)gvDetails.FooterRow.FindControl("txtpname");
TextBox txtprice = (TextBox)gvDetails.FooterRow.FindControl("txtprice");
crudoperations("INSERT", txtname.Text, txtprice.Text, 0);
}
}
protected void gvDetails_RowEditing(object sender, GridViewEditEventArgs e)
{
gvDetails.EditIndex = e.NewEditIndex;
BindGridview();
}
protected void gvDetails_RowCancelingEdit(object sender, GridViewCancelEditEventArgs e)
{
gvDetails.EditIndex = -1;
BindGridview();
}
protected void gvDetails_PageIndexChanging(object sender, GridViewPageEventArgs e)
{
gvDetails.PageIndex = e.NewPageIndex;
BindGridview();
}
protected void gvDetails_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
int productid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["productid"].ToString());
TextBox txtname = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtProductname");
TextBox txtprice = (TextBox)gvDetails.Rows[e.RowIndex].FindControl("txtProductprice");
crudoperations("UPDATE",txtname.Text,txtprice.Text,productid);
}
protected void gvDetails_RowDeleting(object sender, GridViewDeleteEventArgs e)
{
int productid = Convert.ToInt32(gvDetails.DataKeys[e.RowIndex].Values["productid"].ToString());
string productname = gvDetails.DataKeys[e.RowIndex].Values["productname"].ToString();
crudoperations("DELETE",productname,"",productid);
}
protected void crudoperations(string status, string productname, string price, int productid)
{
using (SqlConnection con = new SqlConnection("Data Source=Suresh;Integrated Security=true;Initial Catalog=MySampleDB"))
{
con.Open();
SqlCommand cmd = new SqlCommand("crudoperations", con);
cmd.CommandType= CommandType.StoredProcedure;
if(status=="INSERT")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productname",productname);
cmd.Parameters.AddWithValue("@price",price);
}
else if(status=="UPDATE")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productname",productname);
cmd.Parameters.AddWithValue("@price",price);
cmd.Parameters.AddWithValue("@productid",productid);
}
else if(status=="DELETE")
{
cmd.Parameters.AddWithValue("@status",status);
cmd.Parameters.AddWithValue("@productid",productid);
}
cmd.ExecuteNonQuery();
lblresult.ForeColor = Color.Green;
lblresult.Text = productname+" details "+status.ToLower()+"d successfully";
gvDetails.EditIndex = -1;
BindGridview();
}
}
