Hi,
I'm using a kendo grid and I want to alter the JavaScript structure before doing the http call.My datasource type is odata.
The problem is as soon as I add the parameterMap the odata $filter, $skip, $top is no longer sent and formatted to odata.
I want to override this for the update operation only.
The example does that but there is no filter implemented (http://demos.kendoui.com/web/grid/editing.html) and therefore it is an incomplete example
.
parameterMap: function(options) {
alert(options.filter.filters[0])
}
I have access to the filters but how can I put back the standard behavior along with my custom needs.
I know there is a toOdataFilter function being used to convert these but struggling how to keep the standard odata support and adding my custom needs.
Anyone has already faced this issue and figure out how to handle this?
Thanks.

Hi,
Greetings,

Currently, you may use the following code to call the default implementation of oData parameter map:
dataSource: { type: "odata", transport: { read: "URL", parameterMap: function(options, type) { options.foo = "bar"; // do something here return kendo.data.transports["odata"].parameterMap(options, type); } },//...}Greetings,

ok now, how can I get the callback string since I have overriten the parameterMap?
transport: {
parameterMap: function(data,operation) {
if (operation == 'read') {
return kendo.data.transports["odata"].parameterMap(data,operation)
}
else {
return {
$operation: function () { return operation},
$callback: function () { return ""},
transport: {
parameterMap: function(data,operation) {
if (operation == 'read') {
return kendo.data.transports["odata"].parameterMap(data,operation)
}
else {
return {
$operation: function () { return operation},
$callback: function () { return ""},

Hi Rosen,
My updates to the server are good. The only problem I have is returning the call back string to the client-side.
When I commit my changes, how can I obtain the callback strin. Since I have override the paramaterMap, the callback string is not sent.
In order to send back in the update response the callback I need to send it to the server along with the models data.
This is to allow me to return:
Thank you.
Example if the http post parameters:

Hello Patrick,

You do not need to get the generated by jQuery callback name and manually send it to the server, with the latest (Q3 SP1 2011+) official version of KendoUI it should be automatically send as $callback. Note that you should make sure you do not set is explicitly.

Thanks. I find out the issue, the dataType="jsonp" was missing. I now have the callback.
I noticed something, the parameter for the read is $callback and for the update/destroy is callback.
Now I returned the proper callback but the grid doesn't update automatically (the red marker remains).
Do I need to do something manually to refresh the grid?

You should verify that the request send to the server during the update/create/delete operations is successive and the success function pass from the DataSource is executed.

The error: method is called when I get a server-side error. I checked for the success status and this method is never called when the update has been perform successfully on the server.
Maybe I need to send a specific code to force the Kendo grid to be refreshed?
....
success: function () {
alert('Record(s) updated successfully.')
},
error: function(e)
{
// Code is the additional field to show in the error message. Title to show is taken from Kendo grid columns object.
alert('Update has failed!'+dtGetErrMsgFromResponseText(e.responseText,'Code', $("#grid").data("kendoGrid").columns));
},
....
