Bug report

The getFiles method does not return correct results when used in the success event. If you upload a file, the method in the success event will return an array with one item. If you remove a file, the same would return again an array with one item.

Reproduction of the problem

  1. Open this Dojo example.
  2. Upload a file and open the console.
  3. Remove the file.

Current behavior

GetFiles returns an array with one item after removing the file from the list.

Expected/desired behavior

The method should return an empty array.

Bug report

MultiSelect with virtualization and tagMode: single deselects items when too many items are selected.

Reproduction of the problem

  1. Download and unzip the attached project.
  2. Run the project.
  3. Start selecting items from the first item on.

For convenience, attached is a small video demonstrating the behavior.

Note: So far I was unable to reproduce the issue in a Dojo example when trying to replicate the configuration from the project.

Current behavior

At some point, the dropdown popup will scroll up, and some items that have been selected, will be deselected. Also, the single tag for the selected items will disappear.

Expected/desired behavior

The component should not be deselecting items, should not scroll up and the tag should not disappear.

Bug report

When an empty array is passed to the MultiSelect's value method inside the deselect event, the item that is deselected remains selected in the MultiSelect.

Reproduction of the problem

  1. Open this Dojo and run it
  2. Expand MultiSelect's popup list and click on "All" item.

Current behavior

The different MultiSelect items are deselected except for the "All" item.

*If the "if" statement is removed from the deselect event function in the Dojo, and only the 'e.sender.value([]);' is kept, the issue is reproducing no matter of the selected item in MultiSelect's popup.

Expected/desired behavior

Calling 'e.sender.value([]);' should remove all items selected in the MultiSelect.
Click on the "Clear values" button to see the expected behavior.

Bug report

When setting a special font of a given paragraph in the Editor component, if the "x" of the Font dropdown is pressed it will reset the font of this text to the default one. If we then want to change the format of a given paragraph(make it bold for example), we select the paragraph and click on the "Bold" button. The text which is being bolded is the one which font was previously reset, not the selected text which we expect to become bold.

Reproduction of the problem

  1. Open this Dojo and select a random text in the Editor
  2. Change the font of the selected text by choosing one from the "Fonts" dropdown
  3. After changing the font keep the text selection and click on the "x" in the "Fonts" dropdown. The font of the selected paragraph will be reset to the default one.
  4. Select a random text chunk in the Editor and click on the "Bold" button.
  5. See that the bolded text is not the one we expect to be, but the text which font we've reset.

The reported behavior is applicable to all styles - bold, italic, underline, text alignment, ul, ol.

Current behavior

When changing the style of a given selected text, after there was a font reset in the Editor, the new formatting we set is being applied on the text which font was reset, not on the selected one.

Expected/desired behavior

No matter the operations performed in the Editor when formatting a selected text, the format changes should be applied to the selected text only.

Hi team,

In kendo spreadsheet if you disable any row by adding enable property to false and apply sort from data tab, then the disable row is changing based on the sort. instead of applying to particular row  it is applying to perticular range and while sorting the row items are changing. The cell properties are not applying there while sorting.

 

link for example: https://dojo.telerik.com/IkoJeMIz

 

please let me know if I am doing anything wrong here.

 

thanks.

Bug report

Currently, the MultiSelect input does not have a placeholder attribute in its rendering. This leads to inconsistency with the other input components such as AutoComplete and ComboBox.

Reproduction of the problem

  1. Open the Dojo example and inspect the rendering of the two components.

Current behavior

Currently, the MultiSelect 'input.k-input-inner' element does not have a placeholder attribute. As a consequence, the color of the placeholder is slightly different than the rest of the input widgets.

Expected/desired behavior

The MultiSelect widgets should have a placeholder attribute in order to be consistent with the rest of the widgets such as AutoComplete and ComboBox
