i am passing all grid data from form tag to controller but getting incomplete data so giving error while parsing "Unterminated string. Expected delimiter"

//code in view

C#

function Export_PDF() {
        var grid = $("#grid").data("kendoGrid");
        var dataSource = (grid != null) ? grid.dataSource : null;
        var filters = (grid != null) ? dataSource.filter() : null;
        var allData = dataSource.data();
        var query = new kendo.data.Query(allData);
        var data = query.filter(filters).data;
        var dataJSON = JSON.stringify(data);        

     
            $('body').prepend("<form method='post' action='Print_PDF_EX' style='top:-3333333333px;' id='tempForm'><input type='hidden' name='data' value='" + dataJSON + "' ></form>");
            $('#tempForm').submit();
       
    }

//in controller accessing form data
string gridData = Request.Form["data"]; // getting icomplete data
//parsing data
JArray results = JArray.Parse(gridData); //here getting above error

It a complete mess! You are adding form on the fly BEFORE the body!!! And you expect to get form values on the server side!?

Solution 1

Even there is no theoretical limit for the size of the post all known implementations limit it. In IIS it is about 4Kb (MaxClientRequestBuffer), in Appache it is unlimited by default but can be changed (LimitRequestBody)...
So, if your data is large enough it will be cut...
In any way your solution is a complete mess...Learn using your tools - KendoUI has built in capabilities to post data to server, you also can use jQuery.ajax variations...

i have tried using ajax also, by it getting all data but not opening dialogue box to open/save pdf
//code
$.ajax({
url: '@Url.Action("Print_PDF", "Controller_Name")',
dataType: 'json',
data: {
gridData: dataJSON
},
ContentType:'application/json; charset=utf-8',
traditional: true,
type: 'POST',
success: OnComplete,
error: OnFail
});

function OnComplete(result) {
alert(result);
}

function OnFail(result) {
alert("OnFail");
}

in controller return type is return File(stream,"application/pdf",filename,);
