The issue is reproducible when the grid consists only from Multi-header columns, the setDataSource() method has been used and one of the columns is initially hidden.

After setting the new data source, the last header gets hidden. The "display: none;" style has been applied to the "th" HTML element.

Steps to reproduce:

1. Create a grid with multi-header columns only.

2. Hide one column initially.

3. Set a new data source via the setDataSource() method.

4. The last column gets hidden.

Bug report

When a string, used as old_text for SUBSTITUTE(text, old_text, new_text, [instance_num]) function, is repeated more than once and the new_text is an empty string, one occurrence of the old_text remains not substituted.

Reproduction of the problem

  1. Go to Spreadsheet Basic usage demo
  2. Add a new sheet
  3. Type ab113abababab11ab in A1
  4. Enter the following formula in B1 =SUBSTITUTE(A1, "ab", "")

NOTE: substituting ab with another string, e.g. cd, replaces all instances of ab as expected.

Current behavior

113ab11 - when ab is repeated more than once in a row, one of its instances remains unchanged to an empty string

Expected/desired behavior

11311

Actual behavior:

User uses down key or mouse scroll to change the time. A 00:00 hour is set instead of chosen hour on blur.

Expected behavior:

A value chosen by user remains selected. It's not changed by the timepicker.

Additional Context:

This problem occurs only when picker.enable(true) is called after component creation and user uses down arrow / mouse scroll to get to the the 'previous' day. When no .enable method is called everything works fine. Please see attached code snippets and gifs.

Dojo link: https://dojo.telerik.com/OZEDuFEg

Bug can be reproduced using the following code snippet:

 $(document).ready(function () {
    // create TimePicker from input HTML element
    var picker = $("#timepicker").kendoTimePicker({
            dateInput: true,
            format: 'HH:mm'
        }).data('kendoTimePicker');
    picker.enable(true)
});

Removing 

picker.enable(true)

fixes the issue

Steps to reproduce:

1. Go to https://demos.telerik.com/kendo-ui/editor/index using IE11

2. Delete a sentence in the editor by repeatedly pressing the backspace key.

Result:

The characters are deleted slowly with noticeable lag and jank.

Investigation

The following profile shows the FPS drop when you repeatedly press backspace.

 

I believe the call to refreshTools is expensive (for IE) and it is invoked on every keyup for backspace.

The expand Icon of the treeview node is being reset, if another node is dropped above/below it.

To reproduce this behavior you can take the Drag and Drop demo of the treeview. In the initial state the "Furniture" node is expanded. If you take the "Decor" node and drop it above the furniture node, the "Furniture" node stays expanded but the icon changes to collapsed.

ADMIN EDIT: workaround: https://dojo.telerik.com/@bratanov/aLigiWaz

The issue does not manifest with R3 2019 SP1.

You can also monitor it in the following GitHub issue: https://github.com/telerik/kendo-ui-core/issues/4820

I have attached a simplified version of my app that reproduces the issue of infinite valueMapper requests.  

Reproduction steps:

  1. Open the example htm file 
  2. Open the browsers dev tools to the network tab and clear any request that have been logged.
  3. Click "Add New Load Stop." Result: A row will added to the list view that contains a combo box and one request to the Orders endpoint will be made.
  4. Set a value for the combo box that was added. Result: No additional request will be made if selecting from first few items in the list.
  5. Click "Add New Load Stop." Result: A second row will be added to the list view that also contains a combo box, a query to the Orders endpoint will be made, and an infinite number of requests will be made to the ValuMapper endpoint.

This is reproducible in both Edge and Chrome browsers.

 

Thank you for your help,

Luke

Bug report

When a cell/row is selected, its first cell is focused and the sheet is scrolled to show it. If a long sheet is scrolled down/right to edit cells, this scroll top/left is very annoying and user unfriendly.
In these scenarios Excel focuses the topmost/leftmost currently visible cell, avoiding sheet scrolling.

Reproduction of the problem

  1. Go to https://demos.telerik.com/kendo-ui/spreadsheet/index
  2. Scroll to the bottom row of Spreadsheet's sheet.
  3. Click in cell B200 to select it.
  4. Click on the header of column C to select the whole column.

NOTE: for rows reproduction select cell AX2, then click on the header of row 2 - sheet is scrolled to the left and cell A2 is focused.

Current behavior

Column C is selected, cell C1 is focused and the sheet is scrolled to top.
The used has to scroll down to the bottom row again to edit data at the bottom of the sheet.

Expected/desired behavior

Column C is selected. The currently visible topmost cell of column C is focused, without scrolling the sheet. Excel works that way
