jQuery Ajax Gridview Crud Operations (Insert, Edit, Update, Delete) in Asp.net using C#, VB.NET

Jul 28, 2015
Introduction

Here I will explain how to implement
jQuery ajax gridview crud operations insert, select, edit, update and delete example with single stored procedure in asp.net using c#, vb.net or jQuery insert, update, delete operations (crud) in asp.net gridview using single stored procedure in c#, vb.net with example.

Description:
  
In previous articles I explained
gridview examples in asp.net, display images from database using handler in asp.net, Bind Dropdownlist selected value in asp.net gridview, gridview rowdatabound event example in asp.net, Delete multiple rows in gridview using checkbox in asp.net and many articles relating to gridview, asp.net, c#,vb.net and jQuery. Now I will explain how to implement jQuery gridview crud operations (insert, select, edit, update) in asp.net with single stored procedure using c#, vb.net with example.

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

<title>jQuery Gridview Crud Operations Example</title>

<asp:GridView runat="server" ID="gvDetails">

After completion of aspx page add following namespaces in codebehind

C# Code


using System;
using System.Collections.Generic;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.Services;
using System.Data;
using System.Data.SqlClient;

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)
{
BindColumnToGridview();
}
}
private void BindColumnToGridview()
{
DataTable dt = new DataTable();
dt.Columns.Add("ProductId");
dt.Columns.Add("ProductName");
dt.Columns.Add("Price");
dt.Columns.Add("Edit");
dt.Rows.Add();
gvDetails.DataSource = dt;
gvDetails.DataBind();
gvDetails.Rows[0].Visible = false;
}
[WebMethod]
public static ProductDetails[] BindGridview()
{
DataTable dt = new DataTable();
List<ProductDetails> details = new List<ProductDetails>();
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(dt);
con.Close();
foreach (DataRow dtrow in dt.Rows)
{
ProductDetails product = new ProductDetails();
product.productid = dtrow["productid"].ToString();
product.productname = dtrow["productname"].ToString();
product.price = dtrow["price"].ToString();
details.Add(product);
}
}
return details.ToArray();
}
public class ProductDetails
{
public string productid { get; set; }
public string productname { get; set; }
public string price { get; set; }
}
[WebMethod]
public static string crudoperations(string status, string productname, string price, int productid)
{
string msg = "false";
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();
msg = "true";
}
return msg;
}

Swastik said...

Delete is not working.
Rest is done.
It will show an error of undefined when it goes to .js file.
What to do..??

Avi13 said...

Er Mayur Patel said...

Edit Is Not Working Rest Is Fine...

I HAVE COPY PASTED Whole Same CODE And I Facing This

<img src=Images/edit.png width=20px height=20px onclick=updatedata(' + result[i].productid + ', "' + result[i].productname + '","' + result[i].price + '")

When I Pass Only ' + result[i].productid + ' It Invokes Updatedata()

But When I Pass Multiple Parameters Like This
(' + result[i].productid + ', "' + result[i].productname + '","' + result[i].price + '")

It Is Not Invoking Updatedata.I Think There Is Problem In Passing Multiple Parameters syntax Please Help Me..

Er Mayur Patel said...

I Resolved It And This Is The Solution...

1).Passing String Parameter...{
'in (img src=Images/edit.png width=20px height=20px onclick=updatedata(' + result[i].productid + ',\'' + result[i].productname + '\',' + result[i].price + ') (img src=Images/delete.png width=20px height=20px onclick=deleterecords(' + result[i].productid + ')(/td /tr');
}

2).For Update Bit Modified Code...
In InsertUpdatData(productid, productname, price, status)

if (prodid != 0 && opstatus == 'UPDATE') {
productid = prodid;
status = opstatus;
}
