I want to show success custom alert on my application. I got some answer from another thred. And I have applied it like this. Controller

 public ActionResult Create([Bind(Include = "Id,SuppName,Pay_Method,Status,Create_By,Create_Date")] M_Supplier m_Supplier)
        {
            if (ModelState.IsValid)
            {
                m_Supplier.Create_By= int.Parse(((System.Security.Claims.ClaimsIdentity)User.Identity).FindFirst("UserId").Value);
                m_Supplier.Status = true;
                m_Supplier.Create_Date = DateTime.Now;
                db.M_Supplier.Add(m_Supplier);
                db.SaveChanges();
                return RedirectToAction("Index", new { ac = "success" });
            }

            return View(m_Supplier);
        }

and the view

 @Html.ActionLink("Back to List", "Index")

    @{
            var parameter = Request.QueryString["ac"];
            //Check parameter here and display Message
            if (parameter == "success")
            {
                <div class="alert alert-success alert-dismissible">
                    <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
                    <strong><i class="fa fa-exclamation-triangle" aria-hidden="true"></i> Record Added Successfully.</strong>
                </div>
            }
        

    }

My concern is, it shows success message when directed to the index again. How can I show that within the create view and then directed to the index view?

CodePudding user response：

You can use the TempData[""] to check the status of your create/update method and if the TempData[""] is having some value then you can display what you wanted to display

public ActionResult Create([Bind(Include = "Id,SuppName,Pay_Method,Status,Create_By,Create_Date")] M_Supplier m_Supplier)
    {
        if (ModelState.IsValid)
        {
            m_Supplier.Create_By= int.Parse(((System.Security.Claims.ClaimsIdentity)User.Identity).FindFirst("UserId").Value);
            m_Supplier.Status = true;
            m_Supplier.Create_Date = DateTime.Now;
            db.M_Supplier.Add(m_Supplier);
            db.SaveChanges();
TempData["msg"]="success";  

            return RedirectToAction("Index");
        }
TempData["msg"]="error";  
        return View(m_Supplier);
    }

and now you can check the value of TempData["msg"] on your view

       //Check parameter here and display Message
        @if (TempData["msg"] !=null)
        {
           if(TempData["msg"].ToString()=="success"){
           <div class="alert alert-success alert-dismissible">
            <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
            <strong><i class="fa fa-exclamation-triangle" aria-hidden="true"></i> Record Added Successfully.</strong>
            </div>
           }                
        }

Or something what you have done is

@Html.ActionLink("Back to List", "Index")

@{
    if (TempData["msg"] !=null)
    {
       if(TempData["msg"].ToString()=="success"){
       <div class="alert alert-success alert-dismissible">
       <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
       <strong><i class="fa fa-exclamation-triangle" aria-hidden="true"></i> Record Added Successfully.</strong>
        </div>
       }

    }        

}
