There are many properties that can be set during initialization that cannot be changed through the API afterwards.

Take the Kendo UI ToolBar for example. You can add a button to the toolbar and set the text, but you cannot change the text afterwards unless you update the element directly. It may seem like a simple thing to change the text of an element, like so: $("#myButton").text("New Text"). However, if you had set the imageUrl as well, setting the text like I did above would remove the image. Knowing that, you could get the text node and update the nodeValue. That may work today but could easily be broken during a Kendo UI update (for example, if the update included a change that wraps the text in a span).

Having to deal with native elements after they have been created by the Kendo UI components is a dangerous practice for developers as it requires an internal knowledge of how elements are rendered based on the different options set. As mentioned above, it is also dangerous as any update could break our code. Therefore, it is imperative to expose methods that allow us to modify any properties through the API (where possible) to allow us to create clean and easy to maintain code.

If you search the feedback, you will see many requests to add a method here and a method there. There is even a related one to this called "Kendo Mobile: Methods to set properties dynamically".

Suggestion: When you have child elements, such as buttons on the toolbar, please allow us to update those widgets directly rather than through the parent. For example, instead of $("#myToolbar").data("kendoToolBar").enable("#myButton"), allow us to do something like this $("#myButton").data("kendoToolBarItem").enable();

Clicking an item in the parent list reveals the child list that replaces the parent list.

At the top of the child list, there is a < back item that allows returning to the parent list.

For examples, see the drawers at:

• https://www.amazon.com/
• https://www.diy.com/ (make the window small enough to display the drawer button)

Add a new Kendo UI component to display a record vertically (Or add an option to the existing grid to change the orientation of the records).

Usually, I was using vertical grid to display a single record but some people might need it to display more than one record (ex: when you compare items on best-buy web site)

The vertical grid could also be used as a property grid (http://www.telerik.com/products/silverlight/controls/propertygrid.aspx).

I'd like to request adding a clear button similar to the Kendo UI ComboBox for the Kendo UI TextBox.

Thank you!

It would be a great help if there was a way to add a Trendline to a line chart in the DataViz collection.  This function is available in excel and other similar programs.

Hi Telerik Team,

We are using latest version (2022.1.412) of the Kendo jQuery tool set. The latest version of Kendo jQuery is using one of the older version of jszip 2.6.1, which is being tagged a vulnerable by our scanning tool. Can you please upgrade the version of jszip in your latest Kendo jQuery (KendoUIProfessional and Telerik.UI.for.AspNet.Mvc5)  

Currently, when a Kendo component is initialized in the TreeList template it should be initialized in databound, expand, collapse events.

• As the nodes are refreshed when they are expanded the components will not appear as expected in case they are not reitinitized in the collapse/expand event handlers.
• In addition, a setTimeout is needed to ensure that the needed elements are rendered when a node is expanded or collapsed. Adding the timeout leads to a flickering that is not a good user experience solution.
  The dojo linked here demonstrates such an example - https://dojo.telerik.com/@NeliKondova/eFaFEveD

I would like the behavior to be enhanced in order to allow initializing the Kendo component in the TreeList template without the need to use the setTimeout function and if possible without reinitializing the components in the expand/collapse event handlers.

CSP is a great security feature. It should be fully supported by Kendo! The best would be some way to precompile Kendo Templates. Second option could be that you can use Kendo + CSP when not using own Kendo Templates at all. 

My marketing department has requested a specific look for a chart. The Moc up image is http://i.imgur.com/Z2hKaei.jpg in order to achive what they are asking I need the Labels to work in the Bullet Charts. 

It would also be great if you could add a label to the Target as pictured in the image. 

By enabling the drilldown feature on charts, clicking the charts should take the user to the next level. 

Hi Team,

I would like to request jQuery 3.7.0 to be supported with Kendo UI for jQuery.  

Thank you! 

TreeMap MVC Demo doesn't show how the colors ranges are achieved.
http://demos.telerik.com/aspnet-mvc/treemap/index

It would be help to show how the color rangers are specified.

I would like a control to accept durations in the format HH:MM, and persist as a number minutes (or maybe optionally fractional hours).  Something similar was suggested here (not by me):

http://www.telerik.com/forums/mobile-time-duration-picker

I have a time keeping application where user need to be able to enter summarize duration amounts on their timesheets, such as 8 hours of Holiday time (entered as "8:00").  It doesn't make sense to enter this as a time range.

We're accomplishing it now with a textbox, a masking library, and a bunch of fragile JS code, but I'd like a control that is natively build for this.

Please support API access for private NuGet feed. It is more friendly to build servers and avoids user information leaking.

Update from 1 Mar 2021 - At the moment we are looking at providing certificate-based access - a relatively new feature that seems to be the current best practice (issue, PR). While it does require a little bit of setup, it does not expose secrets in the URL, and does not require user credentials.

This is a proposal to have the excelExport function allow an array of columns to be passed through to it. This will then allow additional (hidden) columns of the grid (that is also available in the datasource) be able to be exported.

I really want Kendo UI to be able to support inserting image header to the exported Excel

i think if support qr code with centric logo very successfull.

Any widget with the Template property should have a TemplateUrl property which allows the markup to be placed into an external html file similar to TemplateUrls in AngularJS components.

Radio buttons fire events and web developers rely on these events to capture data or initiate a process. I fail to understand why something so basic to a control is overlooked, yet you provide this functionality to most of your other controls.
