Bug report

JPG images can be cropped only in 2 directions: right to left and bottom to top.

Reproduction of the problem

Reproducible in the demos.

Current behavior

Expected/desired behavior

Images can be cropped in all directions.

Environment

• Kendo UI version: 2020.3.1021
• jQuery version: x.y
• Browser: [all]

If a large number of files are moved using the drag & drop feature, it is very likely that some will get permanently deleted in the process. This is due to the Destroy routine being initiated before the Create routine has completed. Using the demo page here https://demos.telerik.com/aspnet-mvc/filemanager I've been able to replicate the loss of files. Steps are simply:

• Create a new folder inside the Images folder
• Drag the 10 images into this new folder
• Drag them back
• Repeat
•  

Almost immediately, you will find there's no longer 10 images as the Create routine fails to complete before the Destroy routine is initiated resulting in 1 or more files being lost. With very little effort, I was able to reduce the 10 images down to 6 - I would class this as critical.

After 1 move operation, the 10 files are now just 8:

Hello, our file manager makes 2 read request in a row when the page is loaded, when we load a new path, and when a directory is clicked in the tree view.

Is this normal?

Thanks!

Bug report

When a Badge is configured in a Button through the Html Helpers in UI for ASP.NET MVC app, the color of the badge is not correctly changed through the ThemeColor helper.

Reproduction of the problem

1. Open the Button Badges Demo - https://demos.telerik.com/aspnet-mvc/button/badges

Current behavior

The color of the badges is not correctly set. For example, even if changing the themes, the color of the "Error" badge is never red (as for example in UI for ASP.NE Core).

Expected/desired behavior

The color of the Badge in a Button should be correctly set by using the ThemeColor option.

Reproduction of the problem

Inspect the PanelBar in the Templates demos (MVC/Core).

Current behavior

The root items are rendered as li elements nested directly within a div wrapping element.

Expected/desired behavior

The li elements should be nested in a ul element.

Note: Consider handling the scenario when a Kendo UI for jQuery PanelBar is initialized from a div element.

I would like to be able to theme other, non-kendo controls to match kendo controls.  Some controls such as textarea i am able to do this with no problem with a k-textbox class, but i would also like to grandularly be able to set just the background to k-theme-background, foreground to k-theme-foreground, etc. This way if i use properties like this, they update with the kendo theme.

As the title says, I'm getting script errors when attempting to perform a delete function with an MVC grid when in MobileMode.Phone.  The attached project will illustrate the problem.  Just run it and select delete button for one of the items in the far right column.  A popup will appear, but don't click either of the buttons on it yet.  Inspect the html with whatever browser you use (I'm using chrome so I just right click and choose select).  There will be a "Cannot read property 'data' of undefined" error.  If you then click the "Delete" button, you'll get a "Cannot read property 'resolve' of undefined".  Then click on the "Cancel" button and you'll get "Cannot read property 'reject' of undefined".  I'll attach a pic showing these errors.

I need to be able to utilize my grid in mobile phone mode and delete items.  Please help with this.

Also, to get this sample project small enough, I removed the files from the MobileSaveError\lib\KENDOUIMVC\2020.3.915.545 folder.  I figure you can replace those easily enough.  Is that the right thing to do in this case?  I thought maybe I could remove the items in the Packages folder as NuGet/VS will usually restore those.  But wasn't 100% sure on that.  So if you can tell me or link me to an article about what we can remove to shrink the project size for samples when we need to send them, that would be great.

Thank you,
Steven

Thank you for the consideration.

Bug report

Reproduction of the problem

1. Go to https://demos.telerik.com/kendo-ui/pdfviewer/index
2. Inspect the zoom level combobox

Current behavior

Empty "title" attribute

Expected/desired behavior

Bug report

Regression introduced in R2 2019.

Reproduction of the problem

Dojo example.

1. Focus the empty line between the two lines with text
2. Press Backspace key

Current behavior

The line is not deleted

Expected/desired behavior

The line is deleted

Another scenario:

1. Click at the beginning of the third line (before "Du").
2. Press Backspace key
3. Press Delete key.

Delete has no effect if Backspace is pressed before that. If you continue pressing Delete, it will work, but once you press Backspace, the next time you press Delete, it won't delete the character that follows the cursor position.

Bug report

TextAreaFor editor is missing in ASP.NET Core and ASP.NET MVC wrappers.

Environment

* **Kendo UI version:** 2020.3.915
* **jQuery version:** 1.12.4
* **Browser:** [all] 

I would like to use the paging buttons on a horizontal timeline to advance to the next and previous event. There is a work around with script but it does not address the first page and last page of the timeline. 

### Bug report

When the GroupPaging option is enabled and the grid is bound to a DataTable, the server error "Value cannot be null" is observed.


### Environment

* **Kendo UI version:** 2020.3.915
* **jQuery version:** 1.12.4
* **Browser:** [all] 

The Spreadsheet does not support cell formatting with exponent (scientific) notation.  For example, a cell currently displays a value as 0.0000000177 while the formula bar displays it as 1.77e-8. When working with scientific data the ability to format a cell value using exponent (scientific) notation would be an extremely valuable feature.

I downloaded the latest version of Kendo UI (Version: 2020.1.406) for MVC and upgraded my project to refer the latest JS, CSS and Kendo.MVC (2020.1.406.545).

NoRecords method is behaving differently in the latest version. While fetching records in progress, it displays the 'No record found' message even before completion of the action method. Please see the below image:

It was not happening in the version 2018.2.516, it was showing the 'No record found' message after completion of the action method and only if there is 0 row returned.

Below is the code of Student.cshtml view:

<h4>Student</h4>
<div class="responstable grid-wrapper custom-dropdown">
    @(Html.Kendo().Grid<Kendo2020Demo.Models.Student>()
    .Name("StudentGrid")
    .Columns(columns =>
    {
        columns.Bound(p => p.Id);
        columns.Bound(p => p.Name);
        columns.Bound(p => p.Address);

    })
              .HtmlAttributes(new { style = " min-height: 100px;" })
              .NoRecords("No record found.")
              .Scrollable()
              .Filterable()
              .Sortable()
              .ColumnMenu()
              .DataSource
                (
                  dataSource => dataSource
                  .Ajax()                               
                  .Read(read => read.Action("GetData", "Home"))
                )
              .Resizable(resize => resize.Columns(true))
              .Reorderable(reorder => reorder.Columns(true))
 )

</div>

Bug report

Using server binding does not render the NoRecords message for the Grid

Reproduction of the problem

	@(Html.Kendo().Grid(new List<Product>())    
		.Name("Grid")
		.Columns(columns => {
			columns.Bound(p => p.ProductID).Groupable(false);
			columns.Bound(p => p.ProductName);
			columns.Bound(p => p.UnitPrice);
			columns.Bound(p => p.UnitsInStock);
		})
		.NoRecords("No records found.")
		
		.Pageable()
		.Sortable()
		.Scrollable() 
		.DataSource(d=>d.Server())
		.Filterable()
		.Groupable()
	)

Workarond

A possible workaround is to use local binding by setting the AJAX binding in the DataSource, but keep the initial server binding:

	@(Html.Kendo().Grid(new List<Product>())    
		.Name("Grid")
		.Columns(columns => {
			columns.Bound(p => p.ProductID).Groupable(false);
			columns.Bound(p => p.ProductName);
			columns.Bound(p => p.UnitPrice);
			columns.Bound(p => p.UnitsInStock);
		})
		.NoRecords("No records found.")
		
		.Pageable()
		.Sortable()
		.Scrollable() 
		.DataSource(d=>d.Ajax().ServerOperation(false))
		.Filterable()
		.Groupable()
	)
