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 ]

Bug report

When using the FileManager initialized using the TagHelper and renaming nested folders a 404 error is thrown.

Reproduction of the problem

1. Run the FileManager TagHelper Demo
2. Create several nested folders
3. Rename a parent folder
4. Rename child folders of the renamed parent folder
5. Rename the same parent folder

Current behavior

A 404 - File or directory not found is returned

Expected/desired behavior

The folder should be renamed

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]

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>

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();
}

Environment

• Kendo UI version: 2020.2.513
• jQuery version: x.y
• Browser: [all]

Bug report

Reproduction of the problem

Reproducible in the Vertical Grouping demo.

1. Select the Timeline view.
2. Add multiple (more than 11) events to a single time slot: screenshot.
3. The slot resizes in height each time a new event is added, however, the more events are added the closer to the slot's bottom border they are pushed.

Current behavior

After adding 11 or more events, the last event starts overlapping the next resource group slot.

Expected/desired behavior

The slot should resize accordingly, based on the number of events shown in it. Events should not be displayed outside of the slot they belong to.

1. Run the attached project.
2. Focus the MultiSelect and type in "bu". The data is filtered and items matching the filter are displayed in the list.

4. Type in "bu" again. The list shows the first "bu" item as selected (expected)
5. Scroll down the list, so that another page of the data is loaded
6. Now scroll up to the first item

Current behavior

The item is no longer highlighted as selected.

Expected/desired behavior

The item is highlighted as selected.

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:

Whenever the foreign key column of the grid is configured for multi checkbox filtering and is nullable, the value of the "null" option is sent to the server as "NaN".

Steps to replicate:

1. Set ForeignKey column

2. Make the column nullable

3. Set the filterable.multi option to true

4. filter by the null value

A sample project with reproduction has been shared in Ticket with ID: 1463089

Bug report

The Core wrapper does not have a "Type" option:

.DependenciesDataSource(d => d
	.Model(m =>
	{
		m.Id(f => f.DependencyID);
		m.PredecessorId(f => f.PredecessorID);
		m.SuccessorId(f => f.SuccessorID);
		**m.Type(f => f.Type);**
	})
	.Read("Read_Dependencies", "Gantt")
	.Create("Create_Dependency", "Gantt")
	.Destroy("Destroy_Dependency", "Gantt")
)

Both the MVC wrapper and the jQuery widget allow to specify a field in the data that will be used as "type". Currently the Core wrapper does not allow specifying a field, and dependencies will work only if the data contains a field named "Type".
