Hi Kevin
Thanks for using Syncfusion Products,
Sorry for the inconvenienced. currently ejDataManager doesn’t have support to handle OData V4, but we can
achieve your requirement with the help of custom adaptor by extending default ej.ODataAdaptor. please follow the code snippet.
We can extend the ej.OdataAdaptor as follows.
|
var ODataV4Adaptor = new ej.ODataAdaptor().extend({
options: {
count: "$count",
search: "$search"
},
onCount: function (e) {
return e === true ? "true" : "";
},
|
beforeSend function will be trigger the event before every server
request.
|
beforeSend: function (dm,
request, settings) { //Will be triggered before every
request to server.
// some services do not support custom header on
crossDomain (CORS) request
if
(!dm.dataSource.crossDomain) {
request.setRequestHeader("DataServiceVersion", "4.0");
request.setRequestHeader("MaxDataServiceVersion", "4.0");
}
},
|
processResponse is used to process the response to the server
|
processResponse: function (data, ds, query, xhr, request) { //used to process the response from server
var count;
if (query &&
query._requiresCount) {
count
= data['@odata.count'];
data =
data.value;
}
return
ej.isNullOrUndefined(count) ? data : { result: data, count: count };
},
|
In the grid load event, we can assign the custom adaptor to the
grid datamanager as follow.
|
@(Html.EJ().Grid<Order>("Editing")
.Datasource(ds => { ds.URL("http://services.odata.org/V4/Northwind/Northwind.svc/Orders/").CrossDomain(true); })//"http://services.odata.org/V4/Northwind/Northwind.svc/Orders/")
.ClientSideEvents(eve => eve.Load("load").ActionComplete("CompleteHandler").ActionBegin("BeginHandler"))
.Render())
</div>
<script>
refContent = false;
function load(args) {
args.model.dataSource.adaptor = new ODataV4Adaptor;
}
</script>
