Exporting to Excel result in corrupted Excel file

Hi, I noticed that when we try out the following sequence, we get a corrupted excel file on export.

Go to https://dojo.telerik.com/IcoRol
Open the excel file (Attached to this thread)
Export to excel

Result: Corrupted Excel file

I have pinpointed that the issue is related to a filter in my excel sheet. I’ve added a filter on a column, sorted from A to Z and that’s when the export issue started occurring. The bad part about it is, once my file contained a filter, even if I remove that filter, the end result will be that on export, it generates a corrupted excel file.

Thanks,
Maxime

Context Menu demo

I'm looking at https://demos.telerik.com/kendo-ui/menu/context-menu and have a question about this piece of code:

var menu = $("#menu"),

original = menu.clone(true);

original.find(".k-state-active").removeClass("k-state-active");

$("#apply").click(function (e) {

e.preventDefault();

var clone = original.clone(true);

menu.getKendoContextMenu().destroy();

clone.appendTo("#example");

initMenu();

});

It clones the menu, it removes the active selection marker from any selected elements and then attaches a click event to all elements with Id = "apply".

But there are no apply elements in the code sample? And running this from the dojo with that code commented out seems to yield the same result.

Is it an example of how to handle context menus on other elements I might choose to put on that page? (but also for left-click though..?)

Confirm Dialog that returns a value

I need a kendo confirm dialog that returns a value.

If OK button is clicked then i need to perform some actions.

If Cancel button is clicked then do nothing.

I have a kendodialog function already created with "OK" and "Cancel" button but it does not behave the way I expect it to behave.

I need the code to wait till the user selects a respoonse and not do any other processing till a user selects any input which would be the case for a normal javascript confirm dialog.

Any example demonstrating the same would be extremely helpful.

01.if (displayConfirmDialog("Do you want to continue ?")) {

02. // do something if function returns "TRUE" i.e. the OK button is clicked

03.}

04.

05.// Test function

06.function displayConfirmDialog(contentText) {

07. var response = false;

08. let dialogDiv = $('<div />').appendTo('body');

09. dialogDiv.attr('id', 'displayDialog');

10. $("#displayDialog").kendoDialog({

11. width: "450px",

12. closable: false,

13. modal: true,

14. content: "<p id = dialogContent>" + contentText + "</p>",

15. buttonLayout: "normal",

16. actions: [

17. {

18. text: "Ok",

19. action: function (e) {

20. closeAndDestroyNotificationDialog(e.sender);

21. response = true;

22. },

23. primary: true

24. },

25. {

26. text: "cancel",

27. action: function (e) {

28. closeAndDestroyNotificationDialog(e.sender);

29. }

30. }

31. ],

32. })

33.

34. $(".k-window-titlebar").addClass("warningDialogTitleBar");

35. $(".k-dialog-title").addClass("warningDialogTitle");

36.

37. return response;

38.}

Upload controller doesn't receive files

I'm using the upload widget and have a problem receiving files server side in an mvc controller.

Javascript code:
$("#file-upload").kendoUpload({
async: {
saveUrl: '@Url.Action("UploadFiles")',
autoUpload: false
},
upload: function(e) {
}
});

Controller signature: public ActionResult UploadFiles(IEnumerable<HttpPostedFileBase> files)

When I debug into the controller method files is null. If I debug into the upload event on the widget I see that it contains the files. Looking at fiddler I also see that the data is sent to the server.

Gantt issue related to export to pdf

I have a problem related to export to pdf in Gantt. When Gantt left side is expanded, and I export to pdf, everything is ok, and all columns are present in exported pdf (see expandedDip.png and expandedDipPdf.png). But when i collapsed it, some columns are not visible in exported pdf (see collapsedDip.png, collapsedDipPdf1.png and collapsedDipPdf2.png). How can I solve this problem? Can I apply scroll for example, or another solution for this?

On itemClick method, e.sender._selectedItemIndex returns previous value

I want to reach selected item's index in the drawer widget. When I examine e.sender from console like this,

console.log(e.sender);

I can find updated value of e.sender._selectedItemIndex.

However, when I want to use e.sender._selectedItemIndex variable directly I get previous value of e.sender._selectedItemIndex. For example, If I open drawer for the first time and select an first item, from console I can see that e.sender's _selectedItemIndex variable is equal to 0 but console.log(e.sender._selectedItemIndex) prints undefined. When I select any other item from drawer, now console.log(e.sender._selectedItemIndex) prints 0. How can I reach and use e.sender._selectedItemIndex's updated value in itemClick function?
