Saving HTML Table Data Manipulated by JQUERY into ASP.NET (Preferrebly Session)
===

I have a few HTML tables and I am using JQUERY to move/shuffle rows from one html table to another. Once the shuffling is completed, I need to find a way to save these tables on server side (preferably in Session) so that they can be retrieved on the next page. 

As first step, I tried to save the altered DOM in ASP.NET Textbox so that I can bring the whole html onto ASP.NET side (and then process it using Vb.NET code to save in session/cache). 

               var html = $('html').clone();
                var htmlString = html.html();

                $('#TextBox1').val(htmlString); 

But I am stuck on the first step where I am getting the following error

"A potentially dangerous Request.Form value was detected from the client (TextBox1.."

Could please someone guide me how can I save these HTML tables on server side so that I can use ASP.NET to read and process them? Should I look for JSON instead?
