Very clear SignalR ASP.NET VB.net chat example

I would like to have a demo website/solution so I can learn more about updating tables on client browsers through SignalR. I need to be able to capture data and validate it before it gets pushed. I'd prefer to be able work with events (Button1_Click). Button1 would relay the information to the database and then on users via SignalR.

Objective:

I need to see how to broadcast to all clients (Person A and Person B get the same table content) - like a chatroom.

I need to see how to broadcast to specific client (Person A sends message to Person B) -- as in a 2 way private message chat.

Most of the examples I've seen online are in C# only and are overly complicated with stock tickers and extra stuff that detracts me from learning the basic workings.

I would like to learn and gain a understanding of how I can display a DataGrid to clients and update the DataGrid with SignalR when the database is changed (add, edit, deleted).

It needs to work with the default asp.net datagrid webcontrol.

Example can be in multiple solutions, or pages, up to you.

For learning purposes: table design:

Table name: tblChat

Columns: ID (int), User (String), Message (String), Timestamp (DateTime), Extra1 (String), Extra2 (String).

Relaying data to the database should be basic code, nothing complex...

For example:

Private Sub SendMessage(ByVal UserName As String, ByVal Message As String, ByVal Extra1 As String, ByVal Extra2 as String)

Dim conn_sql As SqlConnection = New SqlConnection(connectionstring)

Dim cmd_SendMessage As SqlCommand = New SqlCommand("SendMessage", connectionstring)

[login to view URL] = [login to view URL]

[login to view URL] = 60

[login to view URL]("@UserName", [login to view URL]).Value = UserName

[login to view URL]("@Message", [login to view URL]).Value = Message

[login to view URL]("@Extra1", [login to view URL]).Value = Extra1

[login to view URL]("@Extra2", [login to view URL]).Value = Extra2

[login to view URL]()

[login to view URL]()

[login to view URL]()

End Sub

Table can be filled with random data.

Requirments: ASP.net, VB.net, SignalR, SQLServer, VB.NET coding. No C#. As clean as possible, meaning all the extra stuff that is not needed please leave out (things like Bootstrap).

Please as basic as it gets. This is meant to learn the basics. I have a good understanding of programming. Bonus awarded to someone who really explains it step by step in the code and allows for it to be easily understood.

Skills: ASP.NET, jQuery / Prototype, Software Development, VB.NET, SQL
