Hi, To the thread below, https://learn.microsoft.com/en-us/answers/questions/1389276/issue-to-ck-editor regarding the last update in the following, how to refer to str within code behind?

Hi @ Peter_1985 1.Determine who is currently logged in There are many ways to do this. I rented here for a simple identity verification. When the verification is successful, save the user information (UserName) to the Session and jump to the Default page. public partial class Login : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Button1_Click(object sender, EventArgs e) { if(TextBox1.Text=="User"&&TextBox2.Text=="123456") { Session["Name"] = TextBox1.Text; Response.Redirect("Default.aspx", false); } if (TextBox1.Text == "User1" && TextBox2.Text == "123456") { Session["Name"] = TextBox1.Text; Response.Redirect("Default.aspx", false); } } } <!DOCTYPE html> <html xmlns="http://www.w3.org/1999/xhtml"> <head runat="server"> <title></title> </head> <body> <form id="form1" runat="server"> <div> UserName:<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox> Password<asp:TextBox ID="TextBox2" runat="server"></asp:TextBox> <asp:Button ID="Button1" runat="server" OnClick="Button1_Click" /> </div> </form> </body> </html> Write code to let the GridView get the data of the database Since the user's comments are to be displayed in the table, we will do the information reading here. public void ReadComments() { SqlConnection conn = new SqlConnection("Data Source=LocalHost;Integrated Security=SSPI;Initial Catalog=Test;"); conn.Open(); string Sql = "select * from dbo.Comments"; SqlCommand sqlCommand = new SqlCommand(Sql, conn); SqlDataAdapter sqlDataAdapter = new SqlDataAdapter(sqlCommand); DataSet ds = new DataSet(); sqlDataAdapter.Fill(ds); GridView1.DataSource = ds; GridView1.DataBind(); conn.Close(); } Since we just jump to this page to read, we need to write it in protected void Page_Load (object sender, EventArgs e) . protected void Page_Load(object sender, EventArgs e) { ReadDate(); } Submissions Since currently we can get the user's UserName and comment Str . So we can store it in a database. protected void Button1_Click1(object sender, EventArgs e) { char[] chs = TextBox1.Text.ToCharArray(); char[] newchs = new char[chs.Length - 7]; for (int i = 3; i < chs.Length - 4; i++) { newchs[i - 3] = chs[i]; } string str = new String(newchs); TextBox1.Text = str; string name = Session["Name"].ToString(); string Sql = "insert into dbo.Comments values('" + name + "','" + str + "')"; SqlConnection conn = new SqlConnection("Data Source=LocalHost;Integrated Security=SSPI;Initial Catalog=Test;"); conn.Open(); SqlCommand sqlCommand = new SqlCommand(Sql, conn); int Count = Convert.ToInt32(sqlCommand.ExecuteNonQuery()); conn.Close(); } Real-time refresh Use asp:timer to refresh in real time so that we can dynamically see other people's comments. <asp:UpdatePanel ID="updPanel" runat="server" UpdateMode="always"> <ContentTemplate> <asp:Timer ID="Timer1" runat="server" Interval="1000" OnTick="Timer1_Tick"></asp:Timer> protected void Timer1_Tick(object sender, EventArgs e) { ReadDate(); } Table: <asp:GridView ID="GridView1" runat="server"></asp:GridView> Best regards, Qi You If the answer is the right solution, please click " Accept Answer " and kindly upvote it.

Hi @Peter_1985

Use Signalr.

1.Nuget installs Microsoft.owin and Microsoft.ASPNET.Signalr.Core.

2.Create a SignalR Hub Class (v2).

 public class ChatHub : Hub
 {
     public void Send(string name, string message)
     {
        
         Clients.All.broadcastMessage(name, message);
     }
 }

3.Create a OWIN Startup Class.

namespace WebApplication9
{
    public class Startup
    {
        public void Configuration(IAppBuilder app)
        {
            // For more information on how to configure your application, visit https://go.microsoft.com/fwlink/?LinkID=316888
            app.MapSignalR();
        }
    }
}

4.Set your page as the start page

Signalr

5.Front-end code:

Good day Qi You,

Thanks a lot. To your approach, it is having two panes (one on the left and another one on the right).

For the talk of two parties, how about the way that A party puts one comment, and B party puts another one (one after another from top to the bottom)?

Hi @Peter_1985

Sometimes a user may post multiple comments. So I think it's probably not necessary to take one person after another. There is one more question I just wanted to show you, so I set up the left and right parts.

I opened two Edge pages! I'm just want to show you.

By the way, I also modified the code based on Ckeditor5. The value returned by Ckeditor5 is fixed with **<p>**a label.

Hi,

I've added the new .aspx page with the classes. When running the deployed page, it does not proceed further after having clicked "Send" below. Please refer to the URL.

Hi @Peter_1985

Check that your script version matches the reference. Reference your own version.

Check if your script is working properly. Your project doesn't even run Ckeditor. Second, try to rename MyHub1 .cs to ChatHub.cs. In addition, this post is too long, I suggest you recreate the post.
