How to use dataModel.method = "POST"

[nghiemhd]

Hi all,
In the page ClaimPortalPage.aspx I have a method like this

[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string GetMyClaimsWithSearch(string caseManagerId, int selectedPage, int pageSize, string sortBy, string searchCondition)
{
   Get data and return json type
}

I use dataModel as below but I can't call GetMyClaimsWithSearch method, it's always call Page_Load()

dataModel = {
 location: "remote",
 method: "POST",           
 getUrl: function () {
               var data = '{ "caseManagerId":"' + caseManagerId + '"'
                    + ', "selectedPage":"' + this.curPage + '"'
                    + ', "pageSize":"' + this.rPP + '"'
                    + ', "sortBy":"' + sortIndx + "-" + sortDir + '"'
                    + ', "searchCondition":"' + claimSearchCondition + '"'
                    + ' }';
                var getObj = {
                    url: "/PortalPage/ClaimPortalPage.aspx/GetMyClaimsWithSearch",
                    data: data
                };
                return getObj;
            },
            getData: function (dataJSON) {                               
                return { curPage: dataJSON.SelectedPage, totalRecords: dataJSON.TotalRecord, data: dataJSON.data };
            }
        };

My question is how to call GetMyClaimsWithSearch method like jquery ajax post?

$.ajax({
 type: "POST",
 url: "/PortalPage/ClaimPortalPage.aspx/GetMyClaimsWithSearch",
 data: data,
 contentType: "application/json; charset=utf-8",
 dataType: "json",
 success: GetDataSuccess,
 error: GetDataFail
});               

And one more question, how to change Content-Type to "application/json; charset=utf-8"? Because I see the Content-Type of pqgrid when use method "POST" is "application/x-www-form-urlencoded; charset=UTF-8".

Looks like it's routing to wrong url because of headers (content-type)

use http://paramquery.com/api#option-dataModel-beforeSend to set appropriate headers.

Although I set contentType in beforeSend method, Content-Type of Request Headers is always "application/x-www-form-urlencoded; charset=UTF-8" and I can't call method GetMyClaimsWithSearch

dataModel.beforeSend = function (jqXHR, settings) {           
  settings.contentType = "application/json; charset=utf-8";
};

Do I set anything else?

Try this and let know whether this fixes your issue.

dataModel.beforeSend = function (jqXHR, settings) {           
  jqXHR.setRequestHeader("Content-Type", "application/json");   
};

Thank you very much.
Now I can post to method GetMyClaimsWithSearch by using
dataModel.beforeSend = function (jqXHR, settings) {           
  jqXHR.setRequestHeader("Content-Type", "application/json");   
};
