Question

I’m using TinyMCE, the text area is replaced with a TextBox, but when I try to update the database with the new text from my textbox, it wont update. Can anyone help me?

My code looks like this

<%@ Page Title="" Language="C#" MasterPageFile="~/Main.Master" AutoEventWireup="true" CodeBehind="default.aspx.cs" Inherits="Test_TinyMCE._default" ValidateRequest="false" %>

<asp:Content ID="Content1" ContentPlaceHolderID="head" runat="server">

    <script type="text/javascript">
        tinyMCE.init({
            // General options

        });
    </script>
</asp:Content>

<asp:Content ID="Content2" ContentPlaceHolderID="ContentPlaceHolder1" runat="server">
    <div>
        <asp:TextBox ID="TextBox1" runat="server" TextMode="MultiLine"></asp:TextBox>

        <br />

        <asp:LinkButton ID="LinkButton1" runat="server" onclick="LinkButton1_Click">Update</asp:LinkButton>
    </div>
</asp:Content>

My codebhind looks like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;

namespace Test_TinyMCE
{
    public partial class _default : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {
            TextBox1.Text = Database.GetFirst().Text;
        }

        protected void LinkButton1_Click(object sender, EventArgs e)
        {
            Database.Update(Database.GetFirst().ID, TextBox1.Text);

            TextBox1.Text = Database.GetFirst().Text;
        }
    }
}

And finally the “Database” class im using looks like this

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Configuration;
using System.Data.SqlClient;

namespace Test_TinyMCE
{
    public class Database
    {
        public int ID { get; set; }
        public string Text { get; set; }

        public static void Update(int ID, string Text)
        {
            SqlConnection connection = new SqlConnection(ConfigurationManager.AppSettings["DatabaseConnection"]);
            connection.Open();

            try
            {
                SqlCommand command = new SqlCommand("Update Text set Text=@text where ID=@id");
                command.Connection = connection;

                command.Parameters.Add(new SqlParameter("id", ID));
                command.Parameters.Add(new SqlParameter("text", Text));
                command.ExecuteNonQuery();
            }
            finally
            {
                connection.Close();
            }
        }

        public static Database GetFirst()
        {
            SqlConnection connection = new SqlConnection(ConfigurationManager.AppSettings["DatabaseConnection"]);
            connection.Open();

            try
            {
                SqlCommand command = new SqlCommand("Select Top 1 ID, Text from Text order by ID asc");
                command.Connection = connection;

                SqlDataReader reader = command.ExecuteReader();
                if (reader.Read())
                {
                    Database item = new Database();
                    item.ID = reader.GetInt32(0);
                    item.Text = reader.GetString(1);
                    return item;
                }
                else
                {
                    return null;
                }
            }
            finally
            {
                connection.Close();
            }
        }
    }
}

I really hope that someone out there can help me

Answer 1

I found another solution. I had to add IsPostBack == false in the codebehind like this.

protected void Page_Load(object sender, EventArgs e) 
    { 
        if (IsPostBack == false)
        {
            TextBox1.Text = Database.GetFirst().Text; 
        }
    }
