I'm currently evaluating the ASP .Net Core Components and whilst I'm liking it so far, I have to say - the documentation leaves a lot to be desired.
At the moment, I am trying to use grid and looking at documentation, I have no idea if I am meant to be looking in Kendo.Mvc.UI.Fluent or Kendo.Mvc.UI - and when I am there and find an item, there just isn't enough detail. In addition, the demos section appears to actually be more helpful and I'm constantly looking there.
What caused me to write this is that I have simply enabled GridFilterMode.Row on an instance and whilst I like it, I want to change the default from "Is Equal To" to "Contains"... I have been experimenting for the past few hours without any luck and I'm going round in circles on documentation:
I can see that Filterable requires GridFilterMode, but the documentation is lacking - https://docs.telerik.com/aspnet-core/api/Kendo.Mvc.UI/GridFilterMode#kendomvcuigridfiltermode
I then try to find the filterable modes documentation, but, half the features/methods just don't seem to have any affect whatsoever.
Personally, I'm having great luck learning about your components from the demo section and adapting the code to suite my needs - but, if there isn't a demo, it appears to be a very hard task to learn what is and isn't possible.
Due to changes in the ASP.NET Core framework and how the Authentication is implemented the MVC5 implementation of the SecurityTrimming option became obsolete.
Implement Recurrence Rule Parser helper that uses the Scheduler recurrenceRule string and parses it in a usable format on the server.
There is already a similar helper for Telerik UI for ASP.NET Ajax.
The Menu TagHelper does not render correct links for its items when the asp-page attribute is used.
With area it does not render a link at all:
<menu-item text="Home" asp-area="Products" asp-controller="Home" asp-action="About"></menu-item>
Without area it renders an incorrect link
<menu-item text="Login" asp-area="Products" asp-page="/Books"></menu-item>
For computations in a custom aggregate function it would be very helpful to have the start and end DateTimes for the current category at hand. Right now the category parameter just provides a single DateTime which is the start DateTime of the category. The end DateTime can only be calculated with a workaround provided by Tsvetina

When certain options of the editable Window are set through configuration, they are not being serialized correctly:
Events (Open, Close, etc.)
I was wanting to create a multiselect filter inside the kendo grid that will filter an array column, NOT a simple string column. Just adding the .Filterable(ftb => ftb.Multi(true)) does display a basic 'multiselect' with just checkboxes in it, which is not ideal , but does work. But, when you click filter, the grid becomes empty. I had to use a clienttemplate() function, to return an html object like so:
My column is:
the code for the foreign key doesn't make much sense as it's an array column, but that was pointed to by telerik support on other forum posts.
So, there must be a way to hook into that column and run some custom code to return to the grid the filtered values? i've seen examples for jquery, and mvc, but theres nothing for .net core. This should just work out of the box, as I don't think this is an uncommon need. Could you give me an example or point me in the right direction?
Hi Kendo Team,
I am working on Kendo UI ASP.NET Core Grid binding with SignalR. But while starting Hub and providing the Promise, I am facing an error "The "promise" option must be a Promise."
I am following this URL for reference: https://demos.telerik.com/aspnet-core/grid/signalr .
In this link, when clicking on "Open In Dojo" button, it opens a new window, then clicks on the Run button. It will generate an error in the console "Uncaught Error: The "promise" option must be a Promise.".
Please check the attached snapshot.
Please reply asap. Thanks in advance!
Trying to attach an event to the Core Sparkline wrapper like this:@(Html.Kendo().Sparkline()
leads to a compilation error:
Error CS0121 The call is ambiguous between the following methods or properties: 'SparklineBuilder<T>.Events(Action<ChartEventBuilder>)' and 'SparklineBuilder<T>.Events(Action<SparklineEventBuilder>)'
When a model property is decorated with data annotation attributes, the RadioButton HtmlHelper does not properly render the data-val and data-val-required attributes on the element.
Expected behavior: Data attributes should be successfully rendered on the <input> element.
When the upload fails (for example, server crashes), the component shows a word "Done" which is quite positive (even technically correct from the point of view of some internal code which participates on sending this files to a server). I vote for using some less positive work like "Failed" or "Some failed" or so which more reflects the user point of view what really happened and triggers a warning that the user should investigate and retry if needed.
I'd like to see the Editable.Window Configuration in TreeLists like in Grids, one would actually expect this configuration to be available on all controls that have an Editable configuration.
On a grid I use this code to set AutoFocus, but it is only available through JQuery on a TreeList.
.Editable(editable => editable.DisplayDeleteConfirmation(false) .Mode(GridEditMode.PopUp) .TemplateName("AccountEditor") .Window(w => w .Scrollable(false).AutoFocus(false) ))
Currently, the functionality for creating a toolbar template with TagHelpers is not available.
While browsing the new components of UI for Asp Core, I found an Issue in the provided online sample (https://demos.telerik.com/aspnet-core/ripplecontainer/index)
After transferring and moving items between the lists of "RIPPLE ON LIST ITEMS", the list display the raw HTML of the items. So, I provided a screen record reproducing the issue (https://pasteboard.co/I7Fx0AW.gif).
It would be very useful if the TimePicker component would have a feature called something like "AutoFocusTime()". By default, when there is no value inside the TimePicker, the default focused time is "12:00 am", therefore the user has to scroll up all the way to the required time. With the feature above, it would be possible to enter a time which should be focused by default. For example "8:00 am" which is when most businesses start operating.
Now the question is, why not just putting in a default value. Well, in a form with lots of inputs, the user may not know anymore which values he entered and which inputs have a default value set and therefore submitting wrong data. If a input doesn't have a default value this mistake can be caught by setting a [Required] attribute. Threfore, the user has to enter a value and it will be guaranteed that all values where entered by him and it wasn't a default value which has been set.
