Hi,

When I call grid.datasource.sync() on a datasource that has a model id defined, but this field is unmapped, I get a cryptic error. You can find a reproducer here: https://dojo.telerik.com/iLacazot

Uncaught TypeError: o is undefined
    setup http://127.0.0.1/a/kendo-ui/js/kendo.all.min.js:28

On a slightly related subject; When checking the docs on the model id it seems that the example is missing from this page:

https://docs.telerik.com/kendo-ui/api/javascript/data/model/fields/id

When a task contains a child task in this scenario we are we are looking for resizing the parent task individually as well as we should be able to resize the parent task along with its corresponding child tasks.

In my project, I'm trying to implement the above scenario but I could not finding anything relevant in the blog.

If the element has the child item so is there a way to resize the parent task also?

Is this feature already implemented?

Hello All,

There should be a feature where we can place radio button group in a matrix format (multiple rows with one header row). It would be very helpful in designing surveys.

Thanks

I am trying to upgrade to jQuery 3.5.1 and as per the documentation regarding compatible KendoUI versions I have upgraded KendoUI to v2021.1.119 (R1 2021). Now even though this version is compatible, I am getting warning messages from jQuery Migrate plugin as follows:

Wondering if this issue is known and support for the issue is on its way. Or else is it reccomended to change the minified JS files as these seems to be simple fixes.

Thanks!

Bug report

When the Editor is used in ExpansionPanel and an image is dragged in the Editor an error is thrown, The issue is reproducible after the ExpansionPanel is collapsed and then expanded.

Reproduction of the problem

1. Open the Dojo example
2. Collapse the ExpansionPanel
3. Expand the ExpansionPanel
4. Drag and drop an image into the inline editor

Current behavior

The image is displayed in a new tab and the following error appears: Cannot read property 'nodeType' of null

Expected/desired behavior

The image should be rendered in the Editor without errors in the console even after collapsing/expanding the ExpasnionPanel

Environment

• Kendo UI version: 2021.2.616

Open this example https://dojo.telerik.com/@lydbell/UcOFiKad.

Run and wait 1 sec.

The selected custom view is lost and the Gantt chart reverts to the weekly view.

Hi,

I'm 100% sure I've found a bug that occurs when trying to load a state into the kendo Filter component.

I've tried this on the example of the official documentation below ("Loading Settings on Demand")

https://docs.telerik.com/kendo-ui/controls/data-management/filter/state#loading-settings-on-demand

Here are some reproduction steps:

1. Click Add expression

2. Add Cost - Is equal to - 25

3. Click Save

4. Click any of the 2 close icons

5. Click Load (This should load in the filter of the cost being 25)

6. Once again, click any of the 2 close icons.

7. Click Save

8. Click Load (This should load all the results since we removed the filters and saved that state.)

9. As you can see, it once again loaded the filter instead of loading in the empty filter object.

Please fix this :)

Kind regards

Hi Team,

I'd like to request for the Kendo UI to be able to facilitate its stylings along with the BootStrap form-control class.  This way, I will not need to add any additional custom CSS for certain components within Kendo UI(TextBox, NumericTextBox...etc). 

Thank you!

1. Create a box with background and text color like below in Excel
   
   
2. Create quickanalysis for it
   
   
   
3. Select Formatting -> Text That Cointains -> Custom Format...
   
   
4. I chose red for the text and orange for the background
   
   
5. The result in excel will be like this and save it
   
   
6. Import it into kendoui spreadsheet
   

This shows up wrong when compared with on Excel.

Hi Team,

I would like to request that in the @progress/kendo-ui npm package to be modified so that the dependencies for jQuery will include <=3.5.1 instead of 3.5.1.  I believe that the package.json should be fixed on NPM or this will cause issues for a lot of people that use jQuery with more than just kendo.

Thank you! 

Hello,

in the Typescript bindings, the JQuery $("...").data("kendoXXX") Methods do not include undefined in there return values.

https://docs.telerik.com/kendo-ui/intro/widget-basics/jquery-initialization#duplicate-initialization

-> in the second script section, it is also documented that it can return undefined, when there is no widget instance found.

It also returns undefined, when the selector doesn't match any element.

Please include undefined in the return values.

Bug report

When the content that is being exported to PDF contains Material Design Icon the exported PDF is not valid.

Reproduction of the problem

1. Open the Dojo
2. Export the file
3. Try to open it with Adobe Reader

Current behavior

Currently, when the file is about to be opened with Adobe Reader the following error appears - 'An error exists on the page. Acrobat may not display the page correctly. Please contact the person who created the PDF document to correct the problem.'.
Also if the file is tested in an online pdf validator it is not considered valid.

Expected/desired behavior

The exported file should be opened in Adobe Reader without any issues.

Environment

• Kendo UI version: 2021.1.330
• Browser: [all ]

Currently, the data-value-update attribute can be used on DOM elements: https://docs.telerik.com/kendo-ui/framework/mvvm/bindings/value#controlling-the-view-model-update

It would be nice, if we have the ability to use it with editor widgets like TextBox, TextArea, NumericTextBox, etc.

I am looking for the kendoui heatmap chart as found on GitHub or at the URL above.
I could just copy what they use on github, but I would prefer to get the kendo CDN all from one place.

Initial usage is just to render activity throughout the day as in github, extra is to track the onClick events as you usually want to trigger a re-query on what happened in that period of the day on that date, driving a details view elsewhere.
Al worse you could have dojo demo of how you would wire up chartjs-chart-matrix to a the Datasource(eg like https://demos.telerik.com/kendo-ui/map/geojson), with a view of how you would have created such a chart that would be good on a PWA app.
Thanks

When a kendoContextMenu is applied to a combobox (html tag select) you are not able to show the select options by tapping it. The behaviour is on mobile browser only (tested iPad and Google Chrome developer tools with device toolbar enabled).

I reproduced the issue in telerik dojo, here is the code.

Currently, when you open an existing Excel file in the Kendo UI spreadsheet, make some changes, then post the changes back to the web server, the print and scaling settings of the original Excel file would be lost.

The Kendo.ooxml.Workbook should preserve those settings.

From Ticket ID 1513253

Message from Aleksandar

Calling the saveAsExcel() method triggers the excelExport event. The Kendo UI Spreadsheet utilizes the Excel export module framework to produce Excel files directly in the browser. The output files are in the OOXML Spreadsheet format with an .xlsx extension as explained here. Setting the forceProxy configuration to true will send the ooxml generated export file to the remote endpoint. However, the kendo.ooxml.Workbook API does not expose a configuration option that would preserve the option for setting the page scaling when printing, thus the configuration is lost. If you would like to see such an option available I can suggest logging a Feature Request in our Feedback Portal.

Now, I am doing with the Spreadsheet. I have a problem. 

When I change font to Japanese, and then I enter characters to cell.

The first character was disabled, other characters displayed normally.

It only cause with Japanese font.

Please help me about this problem

Hi,

I want simply a way to check that the cell value is valid when the user presses submit button on the page.

Currently, validation works when a value is entered in a cell by the user. I want validation to work when the value is changed through a formula. or i need a function that i can run manually that tells which cell validation has failed.

It would be good to have the export hierarchy grid to CSV format as build-on support.

I have referred couple of articles and dojo, but didn't find any straight forward solutions.
