Toastr notifications after ImageButton is Clicked C# aspx – Asp.net

Pheww, just found a solution for my question, here it is. You can put this code in the master page content head or aspx content head:

<script type="text/javascript" src="//cdn.jsdelivr.net/jquery/1/jquery.min.js"></script>

 <link media="screen" rel="stylesheet" type="text/css" href="//cdnjs.cloudflare.com/ajax/libs/toastr.js/latest/css/toastr.css" />

    <script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/toastr.js/2.0.1/js/toastr.js"></script>



  <script type="text/javascript">

      function success(msg) {

          toastr.options = {
              "closeButton": true,
              "debug": false,
              "newestOnTop": false,
              "progressBar": false,
              "positionClass": "toast-top-right",
              "preventDuplicates": false,
              "onclick": null,
              "showDuration": "300",
              "hideDuration": "1000",
              "timeOut": "5000",
              "extendedTimeOut": "1000",
              "showEasing": "swing",
              "hideEasing": "linear",
              "showMethod": "fadeIn",
              "hideMethod": "fadeOut"
          }

          toastr.success(msg, "Success");

          return false;

      }



  </script>
    
  <script type="text/javascript">

      function error(msg) {

          toastr.options = {
              "closeButton": true,
              "debug": false,
              "newestOnTop": false,
              "progressBar": false,
              "positionClass": "toast-top-right",
              "preventDuplicates": false,
              "onclick": null,
              "showDuration": "300",
              "hideDuration": "1000",
              "timeOut": "5000",
              "extendedTimeOut": "1000",
              "showEasing": "swing",
              "hideEasing": "linear",
              "showMethod": "fadeIn",
              "hideMethod": "fadeOut"
          }

          toastr.error(msg, "Error");

          return false;

      }



  </script>

Plus put this code in the aspx.cs like this one

protected void Test_Click(object sender, EventArgs e){
 ScriptManager.RegisterStartupScript(this, typeof(Page), "Success", "<script> success('Item added to Cart')</script>", false);
}

Also this is also compatible with datalistitems with buttons or image button like this one:

if (e.CommandName.Equals("AddtoCart"))
            {
                img = (Image)e.Item.FindControl("Img") as Image;
                name = (Label)e.Item.FindControl("lblProdName");
                price = (Label)e.Item.FindControl("lblProdPrice");
                stock = (Label)e.Item.FindControl("lblProdStock");
                tx = (TextBox)e.Item.FindControl("txtQty");

                String n = name.Text.Trim();
                String p = price.Text.Trim();


                if (Session["Username"] == null)
                {
                    ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "swal('You must Login first!','Redirecting to Login......', 'error').then((value) => { window.location ='Login.aspx'; });", true);
                }
                else
                {
                    
                    if (tx.Text == null || tx.Text == "0" || tx.Text == "")
                    {
                       // ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "swal('Error', 'Select Quantity!', 'error');", true);
                        ScriptManager.RegisterStartupScript(this, typeof(Page), "Success", "<script> error('Select Quantity')</script>", false);
                    }

                    else if (ValueExist(n))//Check if item exist on cart
                    {
                       // ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "swal('Error', 'Item already in Cart!', 'error');", true);
                        ScriptManager.RegisterStartupScript(this, typeof(Page), "Success", "<script> error('Item already in Cart')</script>", false);
                    }
                    else
                    {
                        int s = Int32.Parse(stock.Text);
                        int q = Int32.Parse(tx.Text);
                        string username = session.Text;
                        int total = Int32.Parse(p) * q;
                        if (q > s)//Checks if stocks is enough
                        {
                            //ScriptManager.RegisterStartupScript(this, this.GetType(), "script", "swal('Error', 'Not Enough Stocks!', 'error');", true);
                            ScriptManager.RegisterStartupScript(this, typeof(Page), "Success", "<script> error('Not Enough Stocks')</script>", false);
                        }
                        else
                        {
                            //insert
                            String str = "insert into Cart values(@user, @img, @name, @qty, @price, @tprice)";
                            con.Open();
                            SqlCommand cmd = new SqlCommand(str, con);
                            cmd.Parameters.AddWithValue("@user", username);
                            cmd.Parameters.AddWithValue("@img", img.ImageUrl);
                            cmd.Parameters.AddWithValue("@name", n);
                            cmd.Parameters.AddWithValue("@qty", q);
                            cmd.Parameters.AddWithValue("@price", p);
                            cmd.Parameters.AddWithValue("@tprice", total);
                            cmd.ExecuteNonQuery();
                            

                            //  Response.Redirect("Menu.aspx");
                            SqlCommand cmd1 = new SqlCommand("SELECT COUNT(*) FROM Cart WHERE Username=@user", con);
                            cmd1.Parameters.AddWithValue("@user", session.Text);
                            Int32 count = (Int32)cmd1.ExecuteScalar();
                            CartItems.Text = count.ToString();
                            noreload.Update();
                            ScriptManager.RegisterStartupScript(this, typeof(Page), "Success", "<script> success('Item added to Cart')</script>", false);
                            con.Close();
                        }
                    }


                }
            }
