Currently the scheduler widget determines the layout based on device type.  Unfortunately this does not provide a fully responsive design.  Modern day responsive websites should look good on any sized screen regardless of device type.  There is also the issue that with new devices constantly coming out the list of devices being checked may become out of date quite quickly.  Another consideration I have when I design an app is that one may not be viewing something full screen on a laptop or desktop computer.  If this is the case then a page can look horrible due to the fact that an assumption is made on screen size because it is a windows device.  I've also seen laptops with screens as small if not smaller than some tablets which also effects the screen size assumption.

Being web developer for a very long time I understand the complexities that would be involved in this change so I'd also like to provide an interim solution that may (but may not be) easier to attain.  In working with your scheduler I had the idea of putting my own logic in to force moble/tablet view.  I was able to accomplish this with very little code except that manually switching the mode (setting the mobile setting to phone or tablet) doesn't work for the scheduler.  If that could be fixed it would at least provide a workaround for the above feature until you figured out how you wanted to handle it long term.


Thank you,

Currently, if we move files/folders from one folder to another, the FileManager sends two requests to the backend - Create and Destroy. The Create method is called to "create"  the files in their new destination and the Destroy method removes the files from their previous location. 

The two methods are executed independently and the results from each of them don't affect the result of the other. There are scenarios in which when we move files, the Create call can fail or be prevented because of limited user rights, but the Destroy method will be executed resulting in files' deletion. The same is applicable in scenarios where the Destroy is unsuccessful. 

It will be a very useful FileManager feature if there is a relation in the Create and Destroy methods' execution.

Type: Feature Request

In a Grid, you can include aggregates from other columns in a footer template. Please add this feature to TreeList.

Also, other useful features would be:

1. Enable or hide footers for expanded nodes. Currently, if there are any footer templates defined, then a footer row is rendered for each expanded node. Please can we have some control over which of these footer rows are rendered. For example, having them rendered only at the top level.

2. Provide some means of controlling whether or not to include child rows' values in the aggregates.

For example, I currently have a TreeList where some values are already the totalled across any child rows - this totalisation is done by our business layer. However, we want to include a Grand total in the footer, This Grand Total needs to be the total values summed on the top-level rows ONLY and not their children. I am having to write custom code to do this.

Hi  Team,


We are  using kendo mvc tooltip on our user form. we show tooltip on right when user focus in input. we want to force the right position always  on tablet and medium devices. but right now, if there is less space on  right, the tooltip auto moves to left. how can we stop this to going  from right to left regardless of space.

I recently added the editor's table insert/edit feature to a project. My customer immediately showed frustration that you can only apply styles and classes to the entire table or one cell at a time. 

It would be great if we could:

  • Select more than one cell, then apply style and classes.
  • Select one or more rows, then apply style and classes.
  • Select one or more columns, then apply style and classes.

We need to always display dates to the client in EST.  We do not store our dates in SQL server as UTC but instead in local EST by default (for a number of different reasons.   A simple option in the grid (and other controls for that matter) to ignore the automatic conversion process would be *Very* helpful.   I have seen lot's of posts in different sites asking for this option.  Thank you.

I would like to suggest an option when installing or upgrading Kendo MVC project to allow selection or deselection of languages for content and scripts. The extra languages add time to loading the web site and slow down publishing. We only need en-UK and en-US for our main project.

We are moving to automated deployment. Currently when upgrading, we have to manually remove the extra languages which are not required. It would be great to have an option in the wizard to do this when installed and this is set as default for upgrading.

It will be very useful functionality to be able to change a tab title with a double click on it - the same as when one double-click on an Excel spreadsheet.

I have a problem with the DataSourceRequest Filters that are passed from grid to controller - they are not deserialized as I would expect it.

At the client side, I pass a single Composite Filter with logic: "or" and several Filter Items with same field and operator, but different values:


At the server side, they are not deserialized in the same form as I would expect, but in a recursive way. I would prefer to not convert the whole filter chain in my own code, only to process it in the same way it was sent from the client

Type: Feature Request

Hi, I am using PanelBare inside the Drawer, and I need to override the default behaviours of the drawer and not to close automatically after tab action, in order to be able to select and navigate inside the Drawer content (Panel Bar, or any other navigable widget).

close the Drawer, can be handled by the user separately from the events of the Drawer Content (Panel Bare Events in my case)

I have a "Timeline Month" view in my kendo scheduler and I would like to make the columns sortable like it is with the Grid component.

We need functionality like this: When the user presses for the first time on the header of a column to sort the table ascending, second time descending and third time to remove the sort.

Check attached picture - if I press on the "January 12" header I expect to reorder the rows in the ascending order of the event name: Abwesend, Geplant, Home Office.

I have identified a discrepancy in behavior of Telerik Spreadsheet vs Excel in treatment of array formulae (multiplication of arrays)


The spreadsheet attached contains two examples on how the difference on how Excel and Kendo spreadsheets handle array formulas is impacting the tool I'm developing.

The first example is a simple multiplication between a one-column range and a two-column range. Since both have the same number of Rows, Excel multiples both columns of Array 2 by the Array 1 and sum them
Kendo instead expects both ranges to have the same dimensions, so the same array formula throws an error when opened on Kendo

The second example is a the sum of a multiplication between two same-sized matrixes, but conditioned to a flag array. If the flag for that row is true, then the multiplication of the elements of that row should be added to the final result. On Excel, it works as expected.
On the other hand, Kendo seems to consider the “Flag” matrix as a 2-column matrix with the second column left blank, so the result is the multiplication of the first column of array 1 by the first column of array two, conditioned by the flag array:

You can check the results uploading the attached spreadsheet to the Demo available online:

Please let me know your feedback and when/if we can expect an alignment of Spreadsheet behavior to Excel's

Kind regards

Timeline should support datasource like most other Kendo MVC component (eg. Grid) with additional data. eg:


                  .DataSource(dt => dt.Read("GetHistory", "Controller").Data("getPersonID"))

I am restoring the filter for a Kendo Grid in a Controller from a stored filter string. When there is an exponential (e.g. 1e-9) as a value, FilterDescriptoractory.Create() throws an exception "Expected RightParenthesis". Looking at the filter string it seems to have the correct number of parentheses.

On some occasions exponentials work but I can not determine under which. Under which conditions will exponentials work in filters?


var filterString = "ShipName~eq~'ShipName1'~and~(Freight~eq~0~or~Freight~gte~1e-9)~and~ShipCity~gt~0";
var filters = FilterDescriptorFactory.Create(filterString);

Please add keyboard scrolling support for the PDFViewer control. Scrolling through files with a lot of pages is very difficult.

It would allow the drawer to be used as a navigation toll and more responsive site if instead of having to build is item via a template to define items like the tabstrip widget and each item defined to support Loadcontentfrom.


              .Items(i =>
                  i.Add().Text("Dimensions & Weights")

Category: Gantt
Type: Feature Request

I would love to see a feature added to the MVC Gantt control that would allow filtering tasks within the Gantt. Currently when we filter tasks in our Gantt using an external filter which filters the datasource tasks are dropped from the result set if their parent tasks do not meet the filter criteria. This is obviously a problem and makes filtering useless when tasks are dropped when they actually meet the criteria. I would like to see the filtering work as the TreeView and TreeList controls do. When you filter a column in those controls the parent items are returned regardless of whether they meet the filter criteria. This is needed in a hierarchical control like the Gantt chart.

This would be a great addition to the control. In the meantime, we'll either leave filtering out of our application or try to find a way to recursively gather all of the parent task ids and include them in our service to return tasks that meet the filter criteria.

Thanks for considering!

i tested the updated pdfviewer of version 2019.3.1023, but it did not work as expected.

I have some questions about usage und customizing

  1. How can i customize the toolbar actions, primary the print action/command? See the dojo link
  2. Is it possible to get the print window result of the pdf viewer?
  3. Is it possoble to call the print command? I tested the execute function, but it doesn't work. I get only an error (this is not an constructor...)
  4. the download function download every time a document.pdf, the assigned name is ignored
