Bug report

When the user creates a folder and tries to add a file to the Editor an error occurs that the file is not found. This behavior is observed only if the application is Core 3.1.

Reproduction of the problem

1. Open Image and File Browser Demo
2. In the ImageBrowser create a folder.
3. Upload an image and try to add it to the Editor

Current behavior

Currently, in the console, an error 404 occurs that the resource is not found.

Expected/desired behavior

The image should be added to the Editor without errors.

Environment

• Kendo UI version: 2010.2.617
• Browser: [all ]

Currently, EditorImageBrowserController of the Editor requires IHostingEnvironment which is outdated in Asp Core 3.1.  The IHostingEnvironment is replaced by IHostEnviornment.

5. Rename the same parent folder

Bug report

Reproduction of the problem

1. Download the excel file attached in Ticket ID: 1469596
2. Open it in the Spreadsheet.
3. Filter a column, for example the "Anatomy" column, deselect all and leave only "Abdo".
4. Filter another column, for example Timepoint Name. Deselect all and select only V31. Note that this value does not match any "Abdo" row. Because of that, in Excel "V31" is not even available in the filter, once the "Anatomy" column is filtered by "Abdo". In the Spreadsheet the second column can be filtered by "V31".

Current behavior

No data is displayed after filtering the second column (expected), but the header is duplicated.

Additional notes: the file has been tested against the Open XML SDK tool and it reports 4 issues related to Fonts, however, the duplication occurs even after modifying the original file and applying an arbitrary font and font-size to the whole document, so that it passes the tool's verification successfully.

Expected/desired behavior

No data is displayed and there is no header duplication.

Environment

• Kendo UI version: 2020.2.607
• jQuery version: x.y
• Browser: [all]

Hi,

I'm having an issue with the TimePickerFor control, it doesn't show the time, only a strange format.

When I declare the control:

            @(Html.Kendo().TimePickerFor(m => m.ShiftStartDt)
                .Deferred()
            )

it only shows a forma of "h:mm tt" instead of the time from the model

When I change the control to a datetime picker, it works fine but I don't want to see the date, only the time.

This works:

            @(Html.Kendo().DateTimePickerFor(m => m.ShiftStartDt)
                .Deferred()
            )

I have debugged the model and the data is correct,

        [Display(Name = "Start Time")]
        public DateTime ShiftStartDt { get; set; }

I have even tried changing the model to TimeSpan but it didn't help

I tried setting the format also on the control and using jquery:

        $("#ShiftStartDt").kendoTimePicker({
            format: "HH:mm"
        });

still always shows "h:mm tt" always, no matter what I do

Regards

Raff

Bug report

Reproduction of the problem

1. Run the attached sample project:
   TelerikAspNetCoreApp100.zip
2. A child node is returned as checked from the server.
3. Note the difference between the state of the parent node checkbox in the Core TreeView (incorrect) and in the Kendo UI TreeView (correct).

Current behavior

The parent node's state remains "unchecked".

Expected/desired behavior

The parent node's state should be "indeterminate".

Workaround:

Attach a DataBound event handler to the TreeView:

<kendo-treeview name="DataRestrictionTree" load-on-demand="false" datatextfield="Name" on-data-bound="onDataBound" >

In the handler call the TreeView's updateIndeterminate API method:

function onDataBound(e) {
	var treeview = $("#DataRestrictionTree").data("kendoTreeView");
	treeview.updateIndeterminate();
}

Hi Telerik Team

We think it might be very useful an component in telerik like this one https://fengyuanchen.github.io/cropperjs/  for rotate, crop, resize, zoom and move. with a picture box like https://ashleydw.github.io/lightbox/#videos-gallery

If you implement this we will very happy

Thank you

Hi Team,

I'd like to request adding a configuration to the Kendo UI Grid or ExcelExport event which would be a setting to autofit the Excel sheet columns instead of changing the workbook.sheets.columns.autowidth. 

Thank you!

When using the following configuration an error is thrown, thus making it unable to set the Grid columns:

<kendo-filemanager name="filemanager" upload-url="@Url.Action("Upload", "FileManagerData")">   
    <views>
        <grid>
            <columns>
                <column field="name"></column>
            </columns>
        </grid>
    </views>
</kendo-filemanager>

The built-in upload components event cannot be handled through the TagHelper:

<kendo-filemanager name="filemanager">
  <upload on-upload="onUpload"></upload>
  ...      
</kendo-filemanager>

Fix TileLayout so it works with IE11.  Currently it displays the items in a list instead of in the grid as expected.
