Making grid accepting simple json data instead of jsonp

How do I make KendoGrid accept simple json data (array of items), instead of having to return a jsonp with a callback? Currently all the examples requires jsonp.

Features not working

Hi,

I am using the latest version of Kendo UI i.e. 2017.3.921. I am trying to include in my solution the kendo-pivot but it seems that some of the features are not working:

1. The configuration option sortable enables the "Sort Ascending / Descending" options in the pivot grid BUT when clicked they do nothing. I tried in local binding demo and added the sortable: true just below the filterable property, and it does not work. I tied the same in the documentation of the sortable configuration setting but the dojo example does nothing

2. I have a kendo-pivot bound to a datasource with remote data of json type. I perform a read operation, the kendo pivot as well as the kendo configurator is populated with data. The pivot has only one Row dimension and no column fields (one measure, only). Should I expand the Row dimension to all its values and force a requery i.e. datasource.read() again the read function of the transport definition is execute OK BUT the statement options.sucess fails with the exception "cannot read property value of undefined"

function preparePivotDS(espqParams, esOptions) {

var qParams = angular.isFunction(espqParams) ? espqParams() : espqParams;

var xParam = {

transport: {

requestEnd: function(e) {

var response = e.response;

var type = e.type;

console.log(type); // displays "read"

console.log(response.length); // displays "77"

},

read: function(options) {

var pqOptions = {};

var executeParams = qParams.Params;

if (executeParams instanceof esGlobals.ESParamValues) {

if (!executeParams.isValidState()) {

var err = new Error($translate.instant("ESUI.PQ.PARAMS_MISSING"));

options.error(err);

throw err;

}

executeParams = executeParams.getExecuteVals();

}

esWebApiService.fetchPublicQuery(qParams.GroupID, qParams.FilterID, pqOptions, executeParams)

.then(function(pq) {

pq = pq.data;

options.success(pq.Rows || []);

})

.catch(function(err) {

$log.error("Error in DataSource ", err);

options.error(err);

});

},

}

};

if (esOptions) {

angular.extend(xParam, esOptions);

}

return new kendo.data.PivotDataSource(xParam);

}

Kendo grid cell refocusing after refresh

I have a selectable, navigatable and editable grid. After I enter a
value in a cell, I have to change the value in the cell under the
updated cell. To show the updated values of both cells, I have to
refresh the grid. When I do that, the edited cell loses focus. I found a
way to refocus the last edited cell during the save event:

save: function (e) {

var focusedCellIndex = this.current()[0].cellIndex; //gets the cell index of the currently focused cell

//...some dataItem saving (dataItem.set()) logic...

this.refresh(); //refreshing the grid instance

setTimeout(function () { //refocusing the cell

return function () {

var focusedCell = $("#grid tr[data-uid='" + dataItem.uid + "'] td:nth-child(" + (focusedCellIndex + 1) + ")");

$('#grid').data('kendoGrid').editCell(focusedCell);

}

}(), 200);

}

The problem is that this works for the first time, but if I try to
re-edit the same cell again, the cell loses focus. When I try to debug,
it seems that this.current()[0].cellIndex returns 0 in the second attempt, and because of that cell focusing isn't working anymore.

Does anyone have any idea why this.current() works for the 1st time, and not for the 2nd time? Are there any other approaches for refocusing the cell?

Grid save event fires before column editor drop down list change event

We're using the approach to show a drop down list in the grid row when a user clicks on the cell. In the change event we're changing values in the grid's data source to match a selection made from the drop down list.

This all seems to work fine, the grid datasource values are being changed, the only problem is that the grid's save event fires before dropDownList's change event.
This is a problem because the grid's dataSource.dataItem values have not been changed yet.

Question is: Why would the grid's save event fire before the change event of the dropDownList. More importantly, is there some other event we can bind to on the dropDownList which will happen before the grid's save event is called?

The importance here is that the grid's save event is calling a refresh on the grid.

Grid foreign key column won't save new dropdown selections, only update existing non null selections

I'm having an odd problem with my KendoUI grid using Odata-V4. I have a foreign key lookup, and if I have a value in the lookup field, I can update it just fine- I get an indicator that the field is dirty and it's updated when I save the grid. However, if there is no value when I load the item, I can choose an item in the dropdown but the selection isn't saved- the grid shows a blank value when I focus away from the foreign key dropdown and I can't save the grid; if I change another value and save it, the FK dropdown didn't set the value in the object. I'm hoping someone's run into this before? Thanks so much for any input.

var dataSource = new kendo.data.DataSource({
type: "odata-v4",
transport: {
read: {
xhrFields: { withCredentials: true },
url: "/odata/ProvisionalAppointments"
},
update: {
xhrFields: { withCredentials: true },
