Question

Here is my jquery code

var ajaxUrl = "AjaxCallHandler.aspx";
function _init_Chart() {

$.ajax({
    type: "GET",        //GET or POST or PUT or DELETE verb
    url: ajaxUrl,       // Location of the service
    data: "OpCode=GetCallAverageReportForGraph&Parms=DeptId^17~Month^10~Year^2012",         //Data sent to server
    contentType: "",    // content type sent to server
    dataType: "string",     //Expected data format from server
    processdata: true,  //True or False
    success: function (responseString) {//On Successful service call
        alert(responseString);
    }
});

return false;

}

Here is my c# code

 protected void Page_Load(object sender, EventArgs e)
    {
        string responseMessage = "";
        string status = "SUCCESS";
        try
        {
            if (Request.QueryString["OpCode"] == null)
            {
                throw new Exception("Invalid Request, OpCode missing.");
            }
            string operationRequested = Request.QueryString["OpCode"];
            string Params = Request.QueryString["Parms"];
            switch (operationRequested)
            {
                case "GetCallAverageReportForGraph":
                    responseMessage = GetCallAverageReportForGraph(Params);
                    break;
                case "GetCallAverageReportDetails":
                    responseMessage = GetCallAverageReportDetails(Params);
                    break;
            }
        }
        catch (Exception exp)
        {
            status = "EXCEPTION";
            responseMessage = exp.Message;
        }
        Response.ClearContent();
        Response.ClearHeaders();
        Response.Write(responseMessage);
    }

I tried putting a breakpoint in the c# code. It is writing Response.Write from c# code but I’m unable to receive the response in jquery code. Can any one point out the issue?

Change the data type string to html or leave it empty for default type
