Kendo UI Grid Fires CRUD Operations multiple times - grid

Question

I've seen this problem in many places but I can't seem to find a solution. So I have defined a Kendo grid with CRUD operations the thing is that the previous fired operations get fired again.
Say you delete entry X and then you add entry Y, the create operation fires and after that the delete operation (for X - which has been deleted) fires again. Same thing if you first create an element and then edit another, it edits the 2nd element and then it re-fires the 1st create statement and inserts a duplicate for the 1st inserted element. If you go on an on with several operations a nightmare happens with all the other previous operations being fired and sent to the controller.
My grid is:
function InitializeIPAddressesGrid(userID) {
selectedUserID = userID;
$(".ipAddresses").kendoGrid({
dataSource: IPAdressesDataSource,
sortable: {
mode: "single",
allowUnsort: false
},
remove: function (e) {
this.refresh();
var canDelete = confirm("Are you sure you want to delete this record?");
if (!canDelete) {
e.preventDefault();
}
},
height: 420,
resizable: true,
pageable: {
refresh: true,
pageSize: 10
},
selectable: "row",
toolbar: ["create"],
editable:{mode: "inline", confirmation:false} ,
columns: [{
field: "IpAddress",
title: "IP Address"
},
{
field: "Status",
title: "Status"
},
{
field: "LockedUntil",
title: "Locked until",
template: "#=kendo.toString(LockedUntil, 'yyyy/MM/dd' )#"
},
{ command: ["edit", "destroy"], title: " ", width: "180px" }
]
});
}
var IPAdressesDataSource = new kendo.data.DataSource({
type: "json",
serverPaging: true,
serverSorting: true,
serverFiltering: true,
pageSize: 10,
//scrollable:false,
transport: {
read: {
url: websiteRootUrl + '/PortalAuthorization/GetIPAddressesList',
},
update: {
url: websiteRootUrl + "/PortalAuthorization/UpdateIP",
dataType: "json",
type: 'POST',
complete: function (e) {
if (e.status != 200) {
alert(eval('(' + e.responseText + ')').Message);
}
}
},
create: {
url: websiteRootUrl + "/PortalAuthorization/CreateIP",
dataType: "json",
type: 'POST',
complete: function (e) {
if (e.status != 200) {
alert(eval('(' + e.responseText + ')').Message);
}
}
},
destroy: {
url: websiteRootUrl + "/PortalAuthorization/DeleteIP",
dataType: "json",
type: 'DELETE',
complete: function (e) {
if (e.status != 200) {
alert(eval('(' + e.responseText + ')').Message);
}
}
},
parameterMap: function (options, operation) {
if (operation == "update" && options) {
return {ipAddress: options.IpAddress ,
status: options.Status ,
lockedUntil: kendo.toString(options.LockedUntil, 'yyyy/MM/dd' ),
pkey: options.ID,
databaseID: selectedDatabaseID };
}
else
if (operation == "destroy" && options)
{
return {
databaseID: selectedDatabaseID,
pkey: options.ID,
userIDParam: selectedUserID
};
}
else
if (operation == "create" && options) {
return {ipAddress: options.IpAddress ,
status: options.Status ,
lockedUntil: kendo.toString(options.LockedUntil, 'yyyy/MM/dd' ),
pkey: options.ID,
userIDParam: selectedUserID,
databaseID: selectedDatabaseID };
}
else
{
options.databaseID = selectedDatabaseID;
options.userID = selectedUserID;
return options;
}
}
},
schema: {
model: {
id: "ID",
fields: {
IpAddress: { type: "string" },
Status: { type: "string" },
LockedUntil: { type: "date" }
}
},
data: function (data) {
return data.Items;
},
total: function (data) {
return data.TotalCount;
}
}
});
My controllers are:
public object UpdateIP(int databaseID, long pkey, string status, string lockedUntil, string ipAddress)
{
var database = [...];
DynamicDataRepository repository = [...];
string query = "...";
repository.ExecuteNonQuery(query);
return new HttpResponseMessage(HttpStatusCode.OK);
}
public object DeleteIP(int databaseID, long pkey, int? userIDParam)
{
var database = [...];
DynamicDataRepository repository = [...];
string query = "...";
repository.ExecuteNonQuery(query);
return new HttpResponseMessage(HttpStatusCode.OK);
}
public object CreateIP(int databaseID, long? pkey, string status, string lockedUntil, string ipAddress, int? userIDParam)
{
var database = [...];
DynamicDataRepository repository = [...];
string query = "...";
repository.ExecuteNonQuery(query);
return new HttpResponseMessage(HttpStatusCode.OK);
}
Do you have any ideea? where I've done something wrong? thanks in advance. P.S. the queries in the controllers work fine.

I fixed the problem, followed OnaBai's suggestion of returning the Updated/Created entity, and in the case of a Delete I returned the ID of the deleted entry.
public object UpdateIP(int databaseID, long pkey, string status, string lockedUntil, string ipAddress)
{
var database = [...];
DynamicDataRepository repository = [...];
string query = [...];
IPList updatedIP = new IPList { ID = pkey, IpAddress = ipAddress, Status = status, LockedUntil = DateTime.Today };
return Json(updatedIP, JsonRequestBehavior.AllowGet);
// return new HttpResponseMessage(HttpStatusCode.OK);
}
Only one mention: in the case of a CREATE, the method didn't seem to work so what I did is in the .complete event of the CREATE operation I did a ipGrid.dataSource.read();
ipGrid.refresh(); - so the operation doesn't repeat itself. ( I read that in this case there might be problem with the model definition - setting the ID field - but I did set that one). Many thanks to OnaBai
