Hello there

Can I send extra POST data to the call to retrieve remote JSON data?

I have tried things like this:

var pivotData = new ej.data.DataManager({
    url: api_url + "report/data/",
    adaptor: new  ej.data.WebApiAdaptor (),
    crossDomain: true,
    type: "POST",
    postData: {"test":1}

However, the post data is just dropped.

In my PivotView call I use something like this:

var pivotTableObj = new ej.pivotview.PivotView({
    dataSourceSettings: {
        dataSource: pivotData,

Any tips would be gratefully received.

Thanks, Chris

Don't worry about this too much. I fell back to using jquery $.post() to perform the calls.

An eventual answer might be nice so I don't need to rely on jquery forever.

You can send data in data manager using “addParams”. Please refer the below documentation for more details about sending POST data. 
Code Snippet: [JavaScript] 
var remoteData = new ej.data.DataManager({ 
        url: 'https://bi.syncfusion.com/northwindservice/api/orders', 
        adaptor: new ej.data.WebApiAdaptor(), 
         crossDomain: true, 
    },new ej.data.Query().addParams('test', "4")) 
Meanwhile, we have prepared sample for your reference. Please find the sample in below link. 
Please let us know if you have any concern.

Hi support,
I'm trying the same thig, but I have to add two parameters to the query.
I have tried
var eventData = new ej.data.DataManager({
url: "eventdata",
offline: true,
adaptor: new ej.data.UrlAdaptor
}, new ej.data.Query().addParams("eventid", "<?=$event->challengeeventid?>").addParams("<?= Yii::$app->request->csrfParam; ?>", "<?= Yii::$app->request->csrfToken; ?>"));
but this does not work. The parameters are not sent to the server.

My backend side works, because if I use
grid.query = new ej.data.Query().addParams("eventid", "<?=$event->challengeeventid?>");
grid.query.addParams("<?= Yii::$app->request->csrfParam; ?>", "<?= Yii::$app->request->csrfToken; ?>");
with datamanger set as
var eventData = new ej.data.DataManager({
url: "eventdata",
offline: false,
adaptor: new ej.data.UrlAdaptor
the grid is populated.
But this does not work with offline: true. Threrefore I tried to add the parameters directly to the datamanager.

How can I work with datamanger in offline mode and add several parameters to the query?

Hi Stephan, 
We are validating the requirement - "To add two parameters in offline" at our end. We will update the further details within two business days (7/17/2020).

We suspect that your requirement is to add two parameters to query and to fetch the data in offline. We have prepared a sample for your reference. Please check the below sample link. 
You can retrieve the parameters in below code. 
If still the problem exists, kindly reproduce the problem in the provided sample and revert us (or) send your sample that replicating the problem.
