Kendo UI Image Browser Loading Mask hangs when adding directory when image(s) exist

We are using Kendo UI for jQuery at version 2022.2.621.

In the Image Browser, at any empty directory level:

Upload 1 or more image(s) - works fine
Add a directory - reload hangs
Cancel the editor and reopen, reopen the Image Browser.
Navigate to the directory you just uploaded an image and added a directory to. The image and directory are there.
Add a second directory - works fine, no reload hang

The issue we are seeing is bolded in step 2 above - reload hangs when adding our first directory to a directory that already has 1 or more images. The behavior is as described in this previous issue:
https://www.telerik.com/forums/image-browser-endless-loading-animation-after-creating-a-folder

I see that it should be fixed in the version we are using, and the very specific circumstance that is causing it for us is strange. After we have a first directory added, we can add additional directories without issue. Also note that I am not able to reproduce our issue in the demo.

We do have a dotnet backend for the Image Browser endpoints that is fully functional and not throwing exception when the issue occurs. Further, there are no JS errors in dev tools.

Kendo UI Gantt jumps timeline somewhere when item is created with pushUpdate

Hi,

I am not sure if this is a bug or expected behavior, but I observed that when I create element in Gantt widget using pushUpdate, gantt timeline "jumps" to some position. For me locally it jumps to today, on example dojo (attached below) it jumps to other position.

I did some debugging locally and as I could see this line in code triggers this focus:

            pushUpdate: function (items) {
                if (!isArray(items)) {
                    items = [items];
                }
                var pushed = [];
                for (var idx = 0; idx < items.length; idx++) {
                    var item = items[idx];
                    var model = this._createNewModel(item);
                    var target = this.get(model.id);
                    if (target) {
                        pushed.push(target);
                        target.accept(item);
                        target.trigger(CHANGE); //FOR ME HERE IT FOCUSES
                        this._updatePristineForModel(target, item);
                    } else {
                        this.pushCreate(item);
                    }
                }
                if (pushed.length) {
                    this.trigger('push', {
                        type: 'update',
                        items: pushed
                    });
                }
            },

Behavior can be observed on this dojo, with the following steps:
- run dojo

- position gantt timeline somewhere in the future (i tried several dates)

- click 'add item' button to add EXAMPLE element via pushUpdate

Result: Gantt "jumps" the timeline (at least for me) to 05.07. - 06.07.

Thank you and regards

Vedad

Using FileManager as file manager for TinyMCE 5/6

Hello,

I am trying to use FileManager as the file manger for TinyMCE 6. I have been able to successfully get it to load in TinyMCE's windowManager dialog. All of the features of the FileManager work, except for uploading files. When I click on the Upload button, or drag and drop a file into the FileManager, nothing happens. When I view the browser console, I see a warning that says: The uploadDialog dialog is not available!

What will cause the uploadDialog to not be able to show?

I am using the FileManager in a plain .html file like so:

<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
<title></title>
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/2022.2.621/styles/kendo.common-bootstrap.min.css" />
<link rel="stylesheet" href="https://kendo.cdn.telerik.com/2022.2.621/styles/kendo.bootstrap.min.css" />
<link href="https://cdn.kendostatic.com/2022.2.621/styles/kendo.bootstrap-main.min.css" rel="stylesheet" type="text/css" />
<link rel="stylesheet" href="telerik-file-manager.min.css" />

<script src="https://kendo.cdn.telerik.com/2022.2.621/js/jquery.min.js"></script>
<script src="https://kendo.cdn.telerik.com/2022.2.621/js/kendo.all.min.js"></script>
</head>
<body>
<div id="filemanager"></div>
<script src="telerik-file-manager.min.js"></script>
</body>
</html>

The jQuery code that I'm using to initialize the FileManager is:

$('#filemanager').kendoFileManager({
initialView: 'grid',
draggable: 'true',
resizeable: 'false',
dataSource: {
schema: kendo.data.schemas.filemanager,
uploadUrl: '/api/telerik-file-manager/upload',
transport: {
read: {
url: `/api/telerik-file-manager/read?filter=${filter}`,
method: 'GET'
},
create: {
url: '/api/telerik-file-manager/create',
method: 'GET'
},
update: {
url: '/api/telerik-file-manager/update',
method: 'GET'
},
destroy: {
url: '/api/telerik-file-manager/delete',
method: 'GET'
}
}
},
contextMenu: {
items: [
{ name: "select", text: "Select File", command: "SelectFile", spriteCssClass: "k-icon k-i-hyperlink-open" },
{ name: "rename" },
{ name: "delete" },
]
}
});

I am using ASP.NET Core 6 and I have the FileManager completely working great on a Razor Page, but I can't get the Upload feature to work when loading it into a TinyMCE windowManager dialog.

Any suggestions would be appreciated.

Adding the data written to the cell to the validation with the changelistiner

Hello,

const processesList: string[] = ["Process 1","Process 2","Process 3"];

I want to add the word I wrote in the cell to the "list of validation" if it is not in the current list.

  SpreadValidation() {
    var spreadsheet = kendo.jQuery(this.spreadsheetEl.nativeElement).data("kendoSpreadsheet");
    var sheet = spreadsheet.activeSheet();
    const processesMerge = '"'+processesList.toString()+'"';
   
    sheet.range("B:AX").validation({
      dataType: "list",
      showButton: true,
      comparerType: "list",
      from: processesMerge,
      allowNulls: true,
      type: "warning"
    }); 
  }

change listener code

   var spreadsheet = kendo.jQuery(this.spreadsheetEl.nativeElement).data("kendoSpreadsheet");
    spreadsheet.bind("changing", this.changeListener);

  changeListener(e) {
    console.log("The netered value is: "+e.data);
    processesList.push(e.data);
    var spreadsheet = $("#spreadsheet").data("kendoSpreadsheet");
    var sheet = spreadsheet.activeSheet();
    const progressMerge = '"'+processesList.toString()+'"';
   
    sheet.range("B:AX").validation({
      dataType: "list",
      showButton: true,
      comparerType: "list",
      from: progressMerge,
      allowNulls: true,
      type: "warning"
    });    
}

I can capture the data I entered in the cell, but I could not add this word to the current validation list. how can I do it ?

My goal is that if the added word is not in the validation list, it will be added, and if there is, it will not repeat the data. in this way, it is always to increase the list and to be able to make a selection from the existing ones.

[Solved] Kendo filter field dropdown not loading.

I have a filter on a datasource which in return updates a grid. The following are the code to filter and its' template handler.

The problem with this is that, I can load the categories at first when I'm creating the filters. But when I save and reload the filter from local storage, the category dropdown does not load. Please help me with this. It loads up only on a fresh filter.

Thanks in advance.

                                .ExpressionPreview(true)
                                .DataSource("DataSource")
                                .Fields(f =>

                                    f.Add(p=>p.AsAtDate).Label("As At Date");
                                }))
