hi guys,, I'm learn how to use sweet alert in ASP.NET CORE MVC, data successfully saved in database but why the message information successfully saved not appear. Where it the mistake in this code. Any help could be appriciate.

this is the DokterController.cs

using Microsoft.AspNetCore.Mvc;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Threading.Tasks;
using AdminLTEMvc.Models;
using Microsoft.Extensions.Configuration;
using System.Data;
using Microsoft.Data.SqlClient;
using Microsoft.Data;
namespace AdminLTEMvc.Controllers
{
public class DokterController : Controller
{
private readonly IConfiguration _configuration;
public DokterController(IConfiguration configuration)
{
this._configuration = configuration;
}
public IActionResult Index()
{
DataTable dt = new DataTable();
using (SqlConnection con = new SqlConnection(_configuration.GetConnectionString("db_klinik")))
{
con.Open();
SqlCommand cmd = new SqlCommand("Select * From Dokter", con);
cmd.CommandType = CommandType.Text;
SqlDataAdapter adap = new SqlDataAdapter(cmd);

Hi,

I did not get where strvalue variable comes from, I think you need to check viewBag value in if condition, Please check in below code,
"text/javascript">
        var Pesan = "@((string)ViewBag.pesan)";
           if (Pesan !== null && Pesan !== '')
           {
               swal("Good job!",Pesan, "success")
        };

@Jignesh Kumar
greate answer sir.. I'm not thorough on this line code
"text/javascript">
       var Pesan = "@((string)ViewBag.pesan)";
          if (strvalue !== null && strvalue !== '')
          {
              swal("Good job!",Pesan, "success")
       };

In your TambahData.cshtml you are using sweet alert but there is a if condition exists which is if (strvalue !== null && strvalue !== ''). I think strvalue is null and due to that reason it is not executing. You can debug that if condition and check what is the value. Thanks
