If that tbldata is string then you can use the function called JSON.stringify(string) and in that Ajax dataType should be json.

For your reference :Difference between JSON.stringify and JSON.parse

Try adding the following in your web.config file.

 <configuration>
   <system.web>
     <httpRuntime maxRequestLength="xxxx" />
   </system.web>
 </configuration>

The default value for maxRequestLength is 4096 (4MB).

Try setting something that is larger that 4MB. That may work for you.

Hope it helps.

@user2996030 check the browser console. There might be some errors with the ajax request – Karthik Chintala Nov 18 '13 at 08:13

passing data in url has a limit depending on navigator (Example)

its better to pass it in request body :

var request = $.ajax({
   url: '../rep/send',
   type: 'POST',
   cache: false,
   dataType: 'json',
   data: {
          tbl: tbldata,
          tblheader : tblheader 
   },
   contentType: 'application/text; charset=utf-8'
});

Edit

create Model :

[DataContract]
public class ReportModel
{
    [DataMember]
    public string tbl {get; set; }

    [DataMember]
    public string tblheader {get; set; }
}

modify controller :

[HttpPost]
[ValidateInput(false)]
public ActionResult SendReport([FromBody] ReportModel data)
{

}

If you will use json (that is a good choice) you need to understand javscript object structure, serialization in client side and deserialization in server side.

remember to encode the data.

in javascript:

  var sJsonData = JSON.stringify({your data});
  ......
  contentType:"application/x-www-form-urlencoded; charset=UTF-8",
  data: "sJsonObject=" + encodeURIComponent(sJsonData),

so your case would look like:

        url: '../rep/send',
        type: 'POST',
        data: "sJsonObject=" + encodeURIComponent(JSON.stringify(para)),
        contentType: 'application/x-www-form-urlencoded; charset=UTF-8',
        ...

server side:

[HttpPost]
public ActionResult ajaxProcess(string sJsonObject = "")
string sUnescapeJsonData = System.Uri.UnescapeDataString(sJsonObject);
