TreeList binding to remote data only supports "jsonp"?

The example in the TreeList binding to remote data uses "jsonp". I tried "json" and it didn't work.

https://demos.telerik.com/kendo-ui/treelist/remote-data-binding

I have 2 questions:

1) does TreeList binding to remote data only support "jsonp"

2) in the example, when clicking on the tree list node, it includes "id=1" in the query string. Is the name "id" hardcoded? Is it configurable to have "studentId=1" in the query string?

Thanks

Frank

Databinder : element undefined after calling clearAllFiles with kendoUpload

Hello,

I defined a custom "required" binding with kendo.data.binders :

kendo.data.binders.required = kendo.data.Binder.extend({
init: function(element, bindings, options) {
Kendo.data.Binder.fn.init.call(this, element, bindings, options);
},
refresh: function() {
var required = this.bindings['required'].get();

$(this.element).prop('required', !!required);
if($(this.element).getKendoUpload()) console.log('required changed');
}
});

And my input file :
<input type="file" data-role="kendoUpload" name="file0" data-bind="required: myCheckFunction">

The console.log display "required changed" correctly but after calling the clearAllFiles/clearFile/removeAllFiles/removeFile method of the kendo upload widget, the log is no longer displayed because "this.element" is undefined.

What the problem ?

I tried to define the required binding in kendo.data.binders.widget.required instead of kendo.data.binders.required but, I don't know why, even if the input is a widget, the event binding is called in the kendo.data.binders.required.

Thanks a lot.

Grid Filter on a string column fails with '.toLowerCase is not a function'

Hi!

I'm getting an error when I try to use the filter row to filter a string value: (d.Status || "").toLowerCase is not a function

Grid:

01.$("#KendoParkingCards").kendoGrid({

02. dataSource: {

03. transport: {

04. read: {

05. url: window.BASE_URL + "Ajax/GetPassInfo",

06. type: "get",

07. dataType: "json",

08. data: { lookupType: lookupType.value(), lookupValue: $("#LookupValue").val() }

09. }

10. },

11. pageSize: 10

12. },

13. sortable: true,

14. resizable: true,

15. pageable: { pageSizes: true, buttonCount: 5 },

16. filterable: { mode: "row" },

17. selectable: "single",

18. columns: [

19. { field: "ParkingCardId", title: "Parking Card Id" },

20. { field: "StaffNo", title: "Staff Id" },

21. { field: "AirportPassNumber", title: "Airport Pass" },

22. { field: "Name", title: "Staff Name" },

23. //{ field: "Status", title: "Status", template: "#= resolveStatusName(Status) #" },

24.

{ field: "Status", title: "Status", template: function (dataItem) { return kendo.toString(resolveStatusName(dataItem.Status)); } },

25.

{ field: "PassIssueDate", title: "Pass Issued On", type: "date", template: "#= kendo.toString(PassIssueDate, 'dd-MMM-yyyy') #", width: 150 },

26.

{ field: "PassExpiryDate", title: "Pass Expired On", type: "date", template: "#= kendo.toString(PassExpiryDate, 'dd-MMM-yyyy') #", width: 150 },

27. { field: "ServiceCode", title: "Service", template: "#= resolveServiceName(ServiceCode) #" },

28. { field: "TerminalId", title: "Terminal", template: "#= resolveTerminalName(TerminalId) #" }

29. ],

30. change: function(e) {

31. var grid = e.sender;

32. var currentDataItem = grid.dataItem(this.select());

33.

34. $('#ParkingCardId').val(currentDataItem.ParkingCardId);

35. console.log($('#ParkingCardId').val());

36. }

37.});

Lines 23 and 24 both produces same error.

Function:

01.function resolveStatusName(statusId) {

02. var result;

03.

04. switch (statusId) {

05. case 0: result = 'Pending Apprvoal'; break;

06. case 1: result = 'Rejected By Admin'; break;

07. case 2: result = 'Manager Approval'; break;

08. case 3: result = 'Rejected By Manager'; break;

09. case 4: result = 'Send To Admin'; break;

10. case 5: result = 'Approved'; break;

11. case 6: result = 'Completed'; break;

12. case 7: result = 'Delivered'; break;

13. case 8: result = 'Cancel'; break;

14. case 9: result = 'Programmer'; break;

15. case 11: result = 'Expired'; break;

16. case 15: result = 'Pending Payments'; break;

17. case 16: result = 'More Info Required'; break;

18. case 17: result = 'Response Given'; break;

19. case 20: result = 'Pending Payment / Third Party'; break;

20. case 21: result = 'Pending Payment / Company'; break;

21.

22. default: result = '?';

23. }

24.

25. return result.toString();

26.}

At runtime, when I try to filter, I get the error. How do I resolve this?

Position and SwipeToOpen Properties Doesn't effect widget

I can successfully change position and swipeToOpen properties of my widget but it doesn't change anything. Position is always left even when I initialize Position property as right. Likely, swipeToOpen is always true even it's property value is false.

I change these values dynamically with the value of a checkbox like below;

->drawerInstance.options.mini =document.getElementById(widgetID+"toggle").checked;

This line of code above changes mini properties and it works perfectly.

->drawerInstance.options.swipeToOpen =document.getElementById(widgetID+"canSwipe").checked;

On the other side, this line of code above changes drawerInstance value properly but I can still use swipe gestures to open the drawer.

Is there are any better ways to change the values of these properties?

Excel export - line breaks in cell not appearing in spreadsheet

This may not be specific just to the grid, but when using the Excel export functionality from a grid, with the 2018 R2 release, line breaks within cells appear not to be present in the generated spreadsheet, when this was not happening with previous releases. The line breaks are definitely present in the data as /r/n characters (I can output it to the console and they appear there).

Has anyone else experienced anything like this?

Regards,

Charlie

Uncaught type error on custom widget binding for kendoNumericTextBox

Hi there,

I wanted to create my own custom widget binding for max configuration of numeric textbox. With that, I found this article which describes on how to bind the max value of a Kendo UI numeric textbox widget. The binding of the element that I want to achieve is like this

<input data-role="numerictextbox" id="numeric" data-bind="value: value, max: max" />

However, when I implement the provided code on this article https://docs.telerik.com/kendo-ui/framework/mvvm/bindings/custom#custom-widget-binding-in-typescript - Custom Widget Binding I got an exception when applyBinding function is called in kendo.all.js. Please see screen shot attached.

Below is my custom widget binding implementation:

var dataStoreData = {

max_lines: 20
max_orders: 50000
max_orders_per_request: 500

}

kendo.data.binders.widget.max = kendo.data.Binder.extend({
init: (widget, bindings, options) => {
// Call the base constructor
kendo.data.Binder.fn.init.call(this, widget.element[0], bindings, options);
},
refresh: () => {
const that = this,
value = that.bindings["max"].get(); // Get the value from the View-Model

$(that.element).data("kendoNumericTextBox").max(value); // Update the widget
}
});

maxResultSettingsViewModel = kendo.observable({
data: dataStoreData,
settings: dataStoreData,
onDataValueChange: changeData => {
console.debug("onDataValueChange event is triggered.", changeData);
},
onClickEvent: clickData => {
console.debug("onClickEvent event is triggered.", clickData);
}
});

// Bind the container element with the observable object
kendo.bind($("#collapsible-content"), maxResultSettingsViewModel);

Did I implement the above code incorrectly? Or, do I need to upgrade to new version of Kendo UI library?. currently, I'm using version 2019.3.1023

Any help is greatly appreciated.

Cheers,

Junius
