Jquery Datatable server side pagination

Question

Hi, I need help I'm not able to implement Server side pagination with JQueryDatatable + WCF seb service.

 

I have written Storeprocedure and all required code and I have tested with Handler and Webservice there it is working as expected but same thing I am trying to implement with WCF Function then it is not working ...

 

I think something I miss on WCF OperationContract Or maybe when I'm calling that function..

 

Here is my code

 

1. WCF

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "GetEmployees")]
string GetEmployees(int iDisplayLength, int iDisplayStart, int iSortCol_0, string sSortDir_0, string sSearch);
public string GetEmployees(int iDisplayLength, int iDisplayStart, int iSortCol_0, string sSortDir_0, string sSearch)
{}

2. AJAX

$('#tblEmpList').dataTable({
"paging": true,
"ordering": true,
"filter": true,
"destroy": true,
"orderMulti": false,
"serverSide": true,
"Processing": true,
"ajax":
{
"url": "/RouMaster/Services/RouService.svc/rest/GetEmployees",
"type": "POST",
"dataType": "JSON"
},
"aoColumns": [
{
"mDataProp": "Id",
"visible": true
},
{ "mDataProp": "EmpName" },
{ "mDataProp": "Address" },
{ "mDataProp": "Phone" }
]
});

But it is not working

 

not going to methods

 

Next i tried

[OperationContract]
[WebInvoke(Method = "POST", UriTemplate = "GetSSFPApplicationList?iDisplayLength={iDisplayLength}&iDisplayStart={iDisplayStart}&iSortCol_0={iSortCol_0}&sSortDir_0={sSortDir_0}&sSearch={sSearch}")]
string GetSSFPApplicationList(int iDisplayLength, int iDisplayStart, int iSortCol_0, string sSortDir_0, string sSearch);

but values are going 0 always ...

 

Can anyone help me how to do actually with WCF

 

I Am not doing any MVC application its normal Asp.net Application with WCF Webservice ...

 

Please someone help me to solve this issue.
