jqGrid ASP.NET WebForms cellurl doesn't work - c#

I would like to edit my data in grid. I can edit it in table and see it but I don't go to the c# method. I tried with ajax but it doesn't work too...Serialization doesn't work too. What is wrong?
[WebMethod]
public static string LoadData()
{
SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter("SELECT * from Employees", cn);
DataSet ds = new DataSet();
da.Fill(ds);
return JsonConvert.SerializeObject(ds.Tables[0]);
}
[WebMethod]
public void UpdateGrid()
{
//code to actually do the update to the database
SqlConnection cn = new SqlConnection(ConfigurationManager.ConnectionStrings["conn"].ConnectionString);
SqlDataAdapter da = new SqlDataAdapter("SELECT * from Employees", cn);
}
}
and JS:
$(document).ready(function () {
$("#btnEmployee").click(function () {
var service = "Default.aspx/LoadData";
var lastsel2;
$.ajax({
url: service,
datatype: "json",
data: "{}",
contentType: "application/json; charset=utf-8",
method: "POST",
success: function (result) {
result = result.d;
jQuery("#EmpTable").jqGrid({
datatype: "local",
colNames : ['Emp numb', 'First name', 'Second name', 'Salary'],
colModel: [
{ name:"Emp_id", index: "Emp_id", width:80, editable: true},

jqgrid navgrid not working inside tabs

I have view showing a list of documents using jqgrid. While I click on the document title in the grid, I created a pop up with partial view and in this partial view up am using Kendo tabs. In one of the tab am using a partial view to load a jqgrid which shows all the Document logs and in this grid my navgrid is not working. When i click on the next button for navigating to next page, it is actually navigating the main page where I have the list of documents. To avoid confusion I used different 'id' for the navgrid in the partial view, but then it showed no next and previous button at all. Could anyone guide me how to add paging to the partial view while not affecting the parent view.
Below is jqgrid code of the main View:
$.ajax(
{
type: "GET",
url: "#Url.Action("GetDocumentFileList", "Document")",
data: "",
dataType: "json",
success: function (data) {
if (data == "SessionTimeOut")
window.location.href = '#Url.Action("SessionTimeOut", "Error")';
var page = data.Page;
var rows = data.Rows;
var colModel = eval(data.Columns);
var colNames = eval(data.ColumnsTitle);
var $grid = $("#datagrid");
$grid.jqGrid({
url: "#Url.Action("GetDocumentFileList", "Document")",
datatype: griddataType,
datastr: rows,
colNames: colNames,
colModel: colModel,
gridComplete: initGrid,
rowList: [25, 50, 75, 100],
ignoreCase: true,
width: null,
shrinkToFit: true,
multiselect: true,
multiboxonly: false,
pager: '#navGrid',
sortname: 'DocumentRegisterID',
sortorder: "desc",
scrollerbar: true,
viewrecords: true,
rowNum: 25,
autowidth: true,
ondblClickRow: function (DocumentRegisterID) {
if (DocumentRegisterID && DocumentRegisterID !== lastsel2) {
$grid.jqGrid('restoreRow', lastsel2);
$grid.jqGrid('editRow', DocumentRegisterID, true, null, successFuncStandardGrid);
lastsel2 = DocumentRegisterID;
}
},
editurl: "#Url.Action("EditDocumentNo", "Document")",
hoverrows: true,
onSelectRow: function () {
return false;
},
here is the jqgrid code for the partial view used in the pop up in main view :
$.ajax(
{
type: "GET",
url: "#Url.Action("DocHistoryEventLog", "Document")",
data: '',
success: function (data) {
var page = data.Page;
var rows = data.Rows;
var $grid = $("#dataeventgrid");
$grid.jqGrid({

datastr: rows,
colNames: ['DocumentRegisterEventLogID', 'Event Type', 'Description', 'Revision', 'Version', 'Log By', 'Log Date', 'Organization Name', 'Document Owner Organization'],

],

gridview: true,

scrollerbar: true,
loadComplete: function () {
highlightFilteredData.call(this);
},
loadError: function (jqXHR, textStatus, errorThrown) {
alert('HTTP status code: ' + jqXHR.status + '\n' +
'textStatus: ' + textStatus + '\n' +
'errorThrown: ' + errorThrown);
alert('HTTP message body (jqXHR.responseText): ' + '\n' + jqXHR.responseText);
}
});
$grid.jqGrid('filterToolbar', { stringResult: true, searchOnEnter: false, defaultSearch: "cn", stype: 'select' });
$grid.jqGrid("navGrid", "#navLogGrid", { add: false, edit: false, del: false, search: false, refresh: true });
$grid.parents('div.ui-jqgrid-bdiv').css("max-height", '270px');

Setting the property loadonce:true in my partial view solved my problem. Thanks

How to perform the search operation in server side in jQGrid using c#?

I have implemented the JqGrid in my application. I have done the edit,delete, insert operations but I am failing in searching the records. I have bind the data from the sql server.
Here is my script
<script type="text/javascript">
jQuery(document).ready(function () {
jQuery.extend(jQuery.jgrid.edit, {
closeAfterEdit: true,
closeAfterAdd: true,
ajaxEditOptions: { contentType: "application/json" },

var postdata = { 'data': postData };
return JSON.stringify(postdata); ;
}
});
jQuery.extend(jQuery.jgrid.del, {
ajaxDelOptions: { contentType: "application/json" },
onclickSubmit: function (eparams) {
var retarr = {};
var sr = jQuery("#contactsList").getGridParam('selrow');
rowdata = jQuery("#contactsList").getRowData(sr);
retarr = { PID: rowdata.PID };
return retarr;
},
serializeDelData: function (data) {
var postData = { 'data': data };
return JSON.stringify(postData);
}
});
$.extend($.jgrid.defaults,
{ datatype: 'json' }
);
jQuery.extend(jQuery.jgrid.search, {
});
$("#contactsList").jqGrid({
url: '/WebService.asmx/GetListOfPersons1',

});
function getAllSelectOptions() {
var states = { 'male': 'M', 'female': 'F' };
return states;
}
</script>
Here I have given the reference for searching in my asmx file like WebService.asmx/searchrow when I click the find button in the popup the cursor is moving to the specified method in the url.
Here is my question how can I get the user entered search parameter name and value to that method to perform the search operation .
I have defined the searchrow method like following
[WebMethod]
public List<Person> searchrow(HttpContext context)
{
return null;
}
Please help me to out from this problem or any other alternative to do the search operation in JQGrid.
thanks

Please help me out.

Try getting data through AJAX call then populate to the grid.
Try this :-
In Code Behind For dummy data :-
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json)]
public static string getData()
{
string data = GetJson();
return data;
}
public static string GetJson()
{
List<LanguageData> dataList = new List<LanguageData>();
LanguageData data1 = new LanguageData();
data1.pkLanguageID = 1;
data1.Language = "Language1";
dataList.Add(data1);
LanguageData data2 = new LanguageData();
data2.pkLanguageID = 2;
data2.Language = "Language2";
dataList.Add(data2);
System.Web.Script.Serialization.JavaScriptSerializer js = new System.Web.Script.Serialization.JavaScriptSerializer();
return js.Serialize(dataList);
}
public class LanguageData
{
public int pkLanguageID { get; set; }
public string Language { get; set; }
}
In aspx page :-
$(document).ready(function () {
GetData();
});
function GetData() {
$.ajax({
type: "POST",
url: "../DirStructure.aspx/getData",
contentType: "application/json; charset=utf-8",
dataType: "json",
//async: false,
success: function (response) {
var item = $.parseJSON(response.d);

jqGrid: Problem using editurl to call RESTful method

This is the code I am using to load my jqGrid:
function getTopics() {
var fid = document.getElementById("SelectFunction").value;
//alert(fid);
$.ajax({
url: "Restful.svc/GetTopics",
data: { functionID: fid },
dataType: "json",
type: "GET",
contentType: "application/json; charset=utf-8",
success: function (data, status, xHR) {
var thegrid = jQuery("#editgrid")[0];
thegrid.addJSONData(JSON.parse(data.d));
$("#editgrid").fluidGrid({ example: "#outerContainer", offset: -10 });
},
error: function (xHR, status, err) {
alert("ERROR: " + status + ", " + err);
}
});
}
function LoadDataIntoGrid() {
var lastcell;
jQuery("#editgrid").jqGrid('GridUnload');
jQuery("#editgrid").jqGrid({
datatype: getTopics,
height: '300px',
colNames: ['TopicID', 'Topic', 'Description', 'Topic Entity', 'Inactive'],
colModel: [
{ name: 'TopicID', index: 'TopicID', width: 200, editable: false, editoptions: { readonly: true, size: 10} },
{ name: 'TopicCode', index: 'TopicCode', width: 100, editable: true, editoptions: { size: 10} },
{ name: 'TopicDescription', index: 'TopicDescription', width: 200, editable: true, editoptions: { size: 30} },
{ name: "TopicEntity", index: "TopicEntity", width: 200, editable: true, resizable: true, edittype: "select", editoptions: { value: returnEntityList()} },
{ name: 'Inactive', index: 'Inactive', width: 60, align: "center", editable: true, edittype: "checkbox", formatter: 'checkbox', formatoptions: { disabled: true} }
],
rowNum: 30,
rowList: [10, 20, 30],
pager: $('#pagernav'),
sortname: 'Topic',
viewrecords: true,
sortorder: "desc",
caption: "Topics",
editurl: "Restful.svc/SaveTopic",
onSelectRow: function (id) {
if (id && id !== lastcell) {
jQuery('#editgrid').jqGrid('restoreRow', lastcell);
jQuery('#editgrid').jqGrid('editRow', id, true);
lastcell = id;
}
}
}).navGrid('#pagernav', { edit: false, add: true, del: false });
}
Everything loads properly, and clicking on a row makes the fields editable like it should. When the enter key is pressed to save the edits the event seems to fire properly, and calls the "SaveTopic" method referenced in the editurl property. At this point I get an error.
If SaveTopic is defined like this:
[OperationContract]
[WebInvoke(Method = "POST", ResponseFormat = WebMessageFormat.Json)]
public void SaveTopic( string TopicCode, string TopicDescription, string TopicEntity, string Inactive, string oper, string id)
{
//Code Here
}
I get this error from jqGrid: "Error Row: 3 Result: 500:Internal Server Error Status: error"
If SaveTopic is defined like this(Method changed to GET):
[OperationContract]
[WebInvoke(Method = "GET", ResponseFormat = WebMessageFormat.Json)]
public void SaveTopic( string TopicCode, string TopicDescription, string TopicEntity, string Inactive, string oper, string id)
{
//Code Here
}
I get this error from jqGrid: "Error Row: 3 Result: 405:Method Not Allowed Status: error"
I can't find anyone else having this problem, and according to the similar example I could find I seem to be doing it correctly. All help is greatly appreciated at this point.

WCF Services only allow HTTP Post requests: Hence they are not RESTFul otherwise they would pass data via the URL in a GET Request.
Your method says it accepts individual items ie a lot of strings. This is incorrect, automatic JSon binding isn't smart enough to bind each item separately. Try creating an information agent with the correct properties and receive that or a JSONResult object and parsing the data yourself. If you rely on automatic binding make sure to use the latest version of the .NET frame work either 3.5 SP1 or higher in which automatic JSon to Model binding is allowed.
Sources: Asp.net, Microsoft MVC 3.0 reference guide, msdn, trirand.com, ect.

I finally managed to to make it work using this work around. It isn't ideal, but it gets the job done. Code changes in bold.
function getTopics()
var fid = document.getElementById("SelectFunction").value;
//alert(fid);
$.ajax({
url: "Restful.svc/GetTopics",
data: { functionID: fid },
dataType: "json",
type: "GET",
contentType: "application/json; charset=utf-8",
success: function (data, status, xHR) {
var thegrid = jQuery("#editgrid")[0];
thegrid.addJSONData(JSON.parse(data.d));
$("#editgrid").fluidGrid({ example: "#outerContainer", offset: -10 });
},
error: function (xHR, status, err) {
alert("ERROR: " + status + ", " + err);
}
});
}
function LoadDataIntoGrid() {
var lastcell;
jQuery("#editgrid").jqGrid('GridUnload');
jQuery("#editgrid").jqGrid({
