Question

Hii Guys!!!.
I have a grid which is populating through jason data.Now I want to retrieve the
jason values using jquery ajax call from server side code…

Below is my server side code…

getGriddahico.ashx

                        string json ="";
                        json = json + "{\n";
                        json = json + " \"page\":\""+intpage+"\",\n";
                        json = json + "\"total\":"+total_pages+",\n";
                        json = json + "\"records\":"+total+",\n";
                        json = json + "\"rows\": [";
                        rc = false;

                        while(rs.Read()){

                            if(rc){
                                json = json + ",";
                            }
                            json = json + "\n{";
                            json = json + "\"price\":\"" + Convert.ToInt32(rs["price"]) + "\",";
                            json = json + "\"cell\":[" + Convert.ToInt32(rs["price"]) + "";
                            json = json + ",\"" + Convert.ToString(rs["username"]) + "\"";
                            json = json + ",\"" + Convert.ToString(rs["ordinal"]) + "\"";
                            json = json + ",\"" + Convert.ToString(rs["toc"]) + "\"]";
                            json = json + "}";

                            rc=true;
                        }
                        json = json +"]\n";

                        json = json +"}";

and Here is my Jquery Ajax Call code.

 $(document).ready(function () {
        $.getJSON('getGriddahico.ashx', function (data) {
            //loop thru  json data
            //data will contain  json values < --
            $.each(data, function (key, val) {
                console.log(val);
            });
        });
    });

Plz guys Help me how to retrive the value from server side datareader to client side variable..
Thanx in advance.

To me it looks as though you are returning a string value which you need to then parse in the JavaScript into a json object.

Use the code $.parseJSON()

$.getJSON('getGriddahico.ashx', function (data) {

    /* convert to json object */
    var json $.parseJSON(data);

    //loop thru  json data
    //data will contain  json values
    $.each(json, function (key, val) {
        console.log(val);
    });
});
