A previously completed bug described here: https://feedback.telerik.com/aspnet-mvc/1476295-moving-files-can-result-in-permanent-deletion seems to have resulted in code that has the potential to delete ALL files if moved a few times.

I have not had a chance to get the latest version since the above mentioned bug was marked as completed, but I have made a couple of attempts to test the new functionality in your Demo system on this page: https://demos.telerik.com/aspnet-mvc/filemanager

Repeating the previous test, I have now found that a few move actions results in what appears at first to be a Copy, rather than a Move, but then a subsequent refresh reveals ALL files have been deleted.

Steps to reproduce on the Demo system:

  • Create a New Folder within the Images folder
  • Select all images and move them to the new folder
  • Open the new folder
  • Select all images and move them back to the Images folder
  • Repeat the Move actions

I found that after repeating, the files did not appear to move, but seemed had been copied. But a refresh of the Demo page shows that all images had been deleted.

Following the above, here are a couple of screenshots:

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.

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

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.

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:

  2. Instead of the default sample.pdf load the Development Plan.pdf file provided in Ticket ID: 1467984
public ActionResult GetInitialPdf(int? pageNumber)
{
    //exception with Development plan.pdf file:
    string filePath = Path.Combine(Server.MapPath("~/Content/web/pdfViewer"), "Development Plan.pdf");

Bug report

Currently the MultiSelect allows a custom tag (one that does not correspond to items in its dataSource) to be displayed as selected. For this to work the MultiSelect must have autoBind disabled and the dataValueField option must be set. Once the widget is bound to data it behaves inconsistently, depending on whether there are other pre-selected items and what their index in the dataSource is.

Reproduction of the problem

Dojo example.

  1. Focus the MultiSelect

Current behavior

The widget is loaded with data, but the custom tag remains. This leads to the following unexpected behavior: after step 1. deselect "Product1". The item is deselected, the "custom" tag is removed from the input area but the "Product1" tag remains. The behavior is different, if initially "custom" and "Product2" are pre-selected.

Expected/desired behavior

Once the widget is bound any custom tags should be removed. The MultiSelect should display only tags for items that are in its dataSource. For a new item to be displayed as selected, it must be added to the dataSource.

Bug report

Regression introduced in R1 2020. Reproducible with the SASS themes, but the Kendo UI script version has effect on the behavior. For example, the behavior is not reproducible if the latest (2020.1.406) SASS theme is used along with an older (2019.2.1023) version of the kendo.all.min.js file.

Reproduction of the problem

Dojo example.

  1. The behavior is exhibited when an event ends at the same time another event starts, as it is demonstrated in the dojo where "Interview" ends and "Meeting" starts at the same time - 06:15.

Current behavior

"Meeting" is displayed below and to the right of "Interview", similarly to how events are displayed when their time spans overlap.

Expected/desired behavior

"Meeting" should be displayed below "Interview".
