Changes to edit cells are lost when clicking the next cell or other rows in the TreeList.

1. Create TreeList that uses both InCell editing and drag-and-drop movement.
2. Click a cell to edit the text.
3. Type a few characters.
4. Click any other cell in the TreeList.
5. The edited cell exits edit mode and the text reverts to its original value.

Dojo Example adapted from TreeList InCell Editing demo (also attached):

https://dojo.telerik.com/@JimmyTheChimp/UpOsAgus

It would be very useful from a visual and functional perspective to be able to view scheduler items in a year view, that seems to be currently unsupported.

It will be good to have a dropdown button in the Kendo suit.

Dear Kendo,

 

I made research about Kendo Spreadsheet control and I found some of unlogical things in example:

1. When I made changes (kendoSpreadsheetCancelChanges.png) in spreadsheet and click on CANCEL CHANGES button, all of these changes aren't removed.

2. Manually reading spreadsheet datasource, all of these changes aren't removed. For example, when I type in console

$("#spreadsheet").data("kendoSpreadsheet").options.sheets[0].dataSource.read();, datasource is reading, but almost all changes are shown. Why?

 

 

Kind Regards,

Marin

Pasting a cell value into multiple selected cells results in only the first cell in the range getting the value.

Steps to reproduce:
1) Go to https://demos.telerik.com/kendo-ui/spreadsheet/index
2) Click on cell B3 (Calzone) and press CTRL-C
3) Click on cell B4, hold the shift key and arrow down until cells B4-B7 are highlighted (or select the B4-B7 range with the mouse)
4) press CTRL-V

The outcome is only cell B4 receives the value of "Calzone".

Expected/desired behavior

All cells B4-B7 should have the value "Calzone".

Hello there,

I am developing a Web application using  Kendo UI Spreadsheet control, but I noticed that when I copy some numbers from a Excel sheet to the spreadsheet and then copy back to Excel, the decimal values are quite different, I mean, the decimal precision has been affected.

For example:

I have the following numbers on a Excel sheet:

1

0.5

0.333333333

0.25

0.2

0.166667

0.142857

0.125

0.111111

0.1

0.090909

0.083333

0.076923

0.071429

0.066667

0.0625

0.058824

0.055556

0.052632

Then, I copy them to the Kendo spreadsheet and I got the following:

100.00%

50.00%

33.33%

25.00%

20.00%

16.67%

14.29%

12.50%

11.11%

10.00%

9.09%

8.33%

7.69%

7.14%

6.67%

6.25%

5.88%

5.56%

5.26%

But when I copy them back to Excel I got this:

1

0.5

0.3333

0.25

0.2

0.1667

0.1429

0.125

0.1111

0.1

0.0909

0.0833

0.0769

0.0714

0.0667

0.0625

0.0588

0.0556

0.0526

Losing many decimals affecting the results of my computation and calculation.

Can you tell me why is this happening?

Thank you some much.

 

 

 

ColorPicker must have an option to revert to "Default color" (set color to null)

Right now, responsive pager functionality cannot be disabled.

Excel export with image for grid

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

There should be a render function of some sort that can be called that changes how the Uploads are displayed.
In the attached image, I uploaded a single file, then two additional files.
Rather than having a set of one and a set of two, I'd prefer to have either a set of three, or three sets of 1. 

 

I understand that the plugin creates an input element for each individual uploading, however, I think there would be value in being able to join or split those files into multiple elements. It may even be beneficial to add and utilize a FileList object in the Kendo Upload object, as this would allow for the uploads to be sorted alphabetically, or by type, and so on. 

 

To recreate the behavior mentioned, simply upload any number of files to an Upload control and then do that one more time. The behavior can be recreated on the Telerik website demos.

Example: https://dojo.telerik.com/uqajAsas

Check the "foo" node. The change event fires for every checked node. It would be better if it fires a single time after all nodes have been checked.

To change the MultiViewCalendar, you have to look for the header classes and manipulate them via javascript after the calendar renders. 

The footer has an API option so you can change it declaratively.

The header also needs an API option, so that we can either adjust the view button's text (by default the button provides a way to change the calendar's view) or to replace the button entirely with something else, like a centered drop-down month selection button (just an example, my use case was to center, bold, and display the title of the calendar while getting rid of the ability to change the view).  Be good if this option handled supported either a string or a template or a function, depending on what is best for the control's future plans.

Please see Demo https://dojo.telerik.com/UNOPUvaB/2

In first data row (Row 3) I create a range of numeric values from a , middle and maximum value.
Validation works perfectly, e.g. when manipulating the Middle value, I cannot go below minimum cell value and not above maximum cell value, until adjusted.

I want to accomplish the same with dates in second data row (Row 4 when I reference another "C4", it looks like validation works as expected, but the Date Picker is broken.

Like the DatePicker - let the DateRangePicker use pre-existing inputs instead of it creating the input markup it itself. Via options or just use the 2 inputs inside a container as the code does right now (`that._endInput = that.wrapper.find('input').eq(1);`).

I use a timebar + sparklines in all our dashboards.

would be great to see an html5 version of the executive dashboard

After updating to the latest version of Kendo UI for jQuery we noticed that the button disabled style appears to be broken.

 

We were able to reproduce the issue using the Dojo.

The steps to reproduce are very simple.

1. Open the DoJo
2. Between the <body> tags place the code below.
3. Select "Kendo UI 2019 R1" for the Library
4. Run the project and click the Disable button.  Notice that the edit box is styled as disabled, but the button is not, but looks enabled, yet is not clickable.
5. Now switch to the previously released library "Kendo UI 2018 R3 SP1"
6. Click run and click the Disable button.  Notice that both the edit box and button appear and act disabled.

 

 

<! Code to put in between tags >

<div id="view">

  <input type="text" data-bind="value: name, disabled: isNameDisabled" />
  <button data-bind="click: disableInput, disabled: isNameDisabled" class="k-button">Disable</button>

<script>
var viewModel = kendo.observable({
    isNameDisabled: false,
    name: "John Doe",
    disableInput: function() {
        this.set("isNameDisabled", true);
    }
});

kendo.bind($("#view"), viewModel);
</script>
</div>

Make Spreadsheet xlsx import failure more user friendly. Currently, when xlsx import fails, the UI thread is blocked and the user needs to reload the page in the browser. The import operation instead could process the file in the background and could return meaningful message without blocking the UI.

Dear Concerned,

1. Launch https://demos.telerik.com/kendo-ui/spreadsheet/index

2. Open attached MultipleSheetsRowHeightIssue.xlsx

3. Please notice there are 3 sheets with default row height 20, 30, 40 respectively (you can check in MS Excel)

4. Now Click export, and open the exported file again 

5. Now we have an issue here - all sheets set to default row height to 40. (It seems that it is setting the last sheet's default row height to all sheets)

Its severe issue, please share a fix or at least provide some workaround.

 

As discussed on the forum (http://www.telerik.com/forums/virtualization-for-treelist) please improve the rendering/scrolling/expanding/collapsing performance of TreeLists with many expanded rows.

Grids support virtualization and work well with hundreds of thousands of rows (http://demos.telerik.com/kendo-ui/grid/virtualization-local-data). Perhaps virtualization can be added to TreeLists to achieve similar results?
