Adding an AdaptiveMode configuration to Editors, similar to UI for Blazor would be beneficial when UI for ASP.NET Core components are used on smaller screens/mobile devices:

https://demos.telerik.com/blazor-ui/dropdownlist/adaptive

I am using TreeList for setting permissions. It seemed a perfect choice until I realized that state of ALL the checkboxes is set to either true or false.

I would like to be able to select checkbox based on the value of record i.e. to be able to save it's state in database, retrieve it, and batch update it.

I know that this behavior can be simulated / achieved by using javascript, but it would be so much better, easier and neater to have it data bound just like all the other columns.

For example, I have an organisational structure on the picture below. We can set permissions on any level. 

I imagine that the syntax could be something like:

@(Html.Kendo().TreeList<OrgStrukturaTree>()
    .Name("treeOrgRO")
    .Columns(columns =>
    {
        columns.Add().Selectable(true).Width("20px");
        columns.Add().Field(e => e.Opis).Width(250);
    })
    .Filterable(false)
    .Sortable(true)
    .DataSource(dataSource => dataSource
        .Read(read => read.Action("ObjektiTree_Read", "Admin"))
        .ServerOperation(false)
        .Model(m => {
            m.Id(f => f.Id);
            m.ParentId(f => f.ParentId);
            m.Expanded(true);
            m.Selected(f => f.Selected);
            m.Field(f => f.Opis);
        })
    )
)

I sincerely hope you would consider this update, as I cannot think of a scenario when I would use checkboxes that are all the same state.

Thank you in advance.

In the ThemeBuilder the controls do not use the latest version.

For instance while playing around with the ThemeBuilder I noticed that the primary button does not look primary like on the demos page.

Also it would be helpful to provide a page where you explain where every color is used.

Want to be able to define dual pager controls in the Grid using GridPagerPostion.

@(Html.Kendo().Grid<Model>()
   .Name("MyGrid")
   .Columns(...)
  .Pageable(p => p.Position(GridPagerPosition.Both))
  .DataSource( ds => ds....)
)

When I configure with GridPagerPosition.Both, I would like the pagers to be on the top and bottom of the grid content.  There is a work around somewhere in the forum but not in the documentations. It works in some page and does not work in others.   I get the following error:

The IR:297:45 is the second line where kendo.ui.Pager is being instantiated (gridWidget.dataSource is undefined):

const wrapper = $('<div class="k-pager-wrap k-grid-pager k-widget k-floatwrap pagerTop"/>').insertBefore(gridWidget.element.children(".k-grouping-header"));
gridWidget.pagerTop = new kendo.ui.Pager(wrapper, $.extend({}, gridWidget.options.pageable, { dataSource: gridWidget.dataSource }));
gridWidget.element.height("").find(".pagerTop").css("border-width", "0 0 1px 0");

The reason for this request is that it should be part of the product as the product evolves relying on the css classes and the ability to add dynamic property to the girdWidget is problematic. 

The 'footer' attribute in the TagHelpers for both the DatePicker and DateTimePicker does not result in any corresponding markup / Javascript configuration on the page created by the view.

Bug report

The StringExtensions -> ToCamelCase method(part of Kendo.Mvc.Extenstions) doesn't return the expected Camel case result.

• More details in ticket # 1458202

Reproduction of the problem

Include the Kendo.Mvc.Extenstions namespace. Define the following in a controller:

        public IActionResult Index()
        {
            string test = "RANDOMStatusId";
            test = test.ToCamelCase();

            return View();
        }

Set a debugger and see the value of the "test" variable.

Current behavior

The returned from the ToCamelCase() method value is "rANDOMStatusId"

Expected/desired behavior

The expected result returned from the ToCamelCase() method value is "randomStatusId"

Environment

• Kendo UI version: 2020.1.219

Dear Telerik

The feature is related to https://www.telerik.com/account/support-center/view-ticket/1594775 this thread.

It is related to a product environment.

Scenario:

1. Save grid options in persistent storage (i.e. DB).
2. Grid operates successfully and return visits operate well with stored options being loaded with the grid.
3. Then the grid column structure or some other feature is amended during a maintenance and development request - the feature setting is contained within the stored options which are loaded with the grid. The grid functions without some of the changes because the options override the changes.
4. Behavior is unwanted so we would have to merge the new options and the old options.

Request:

Please can Telerik create functionality along the lines of:

$("#SomeGrid").data("kendoGrid").setOptions($("#SomeGrid").data("kendoGrid").mergeOptions(OptionsSaved, OptionsNew));

It would be great if the scaffolder can use an existing model (one that I created before starting the scaffolder). I also would like to have the option to select a namespace:

Trying to attach an event to the Core Sparkline wrapper like this:

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>)'

### Bug report

When Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package is installed in Telerik UI for ASP.NET Core application, it throws an exception:

FileNotFoundException: Could not load file or assembly 'Microsoft.DotNet.InternalAbstractions, Version=1.0.0.0, Culture=neutral, PublicKeyToken=adb9793829ddae60'. The system cannot find the file specified.

### Reproduction of the problem

1. Create Telerik UI for ASP.NET Core MVC application (.NET Core version 6.0).

2. Install Microsoft.AspNetCore.Mvc.Razor.RuntimeCompilation NuGet package (version 6.0.5).

3. Turn on the Razor Runtime Compilation:

//Program.cs file

// Add services to the container.
builder.Services.AddControllersWithViews()
                .AddNewtonsoftJson(options => options.SerializerSettings.ContractResolver = new Newtonsoft.Json.Serialization.DefaultContractResolver())
                .AddRazorRuntimeCompilation();

4. Run the application and review the exception.

Attached is a runnable sample for reproduction.

### Workaround

Install Microsoft.DotNet.InternalAbstractions NuGet package (version: 1.0.0)

### Environment

* **Kendo UI version: 2022.2.510
* **jQuery version: 1.12.4
* **Browser: [all]

Hello,

I am working with application where I have thousands of images to load on ImageBrowser of Kendo Editor.

ImageBrowser is getting stuck as having too many images to load, Can we have any option to add pagination or lazy loading in ImageBrowser?

So, I can load only 20 images at a time and other based on request.

Thanks,

Trusha

My license doesn't include support so this is the only way I could reach out to you. On this page, the line

.Read(r ==> r

should have => instead of ==>. When I pasted this into visual studio, it was giving me completely unrelated error and took me a bit to figure out what was wrong. Please fix the typo.

It would be useful to have a grid operator for "IN" conditions. Right now we only have 2 options for an OR without having to use a custom filtering and custom clearing functions.

We have a lot of data that needs to be filtered that is not sequential.  For example purposes:

Given that a customer has a standing purchase order for parts over time.

Given that serial numbers on said parts will not be sequential and may not be even be similar enough for wildcards (if that feature is provided.)

Given that we need to filter grid data to retrieve customer number, purchase order and a set of serial numbers, we need the equivalent of:

SELECT * FROM testdatatable WHERE customer = '#####' AND purchaseorder = '#####' AND serialnumber IN ('abciqwe', 'cid235', 'sn34087', 'hpk2679');

which would be WHERE WHERE customer = '#####' AND purchaseorder = '#####' AND (serialnumber  = 'abciqwe' OR serialnumber =  'cid235' OR serialnumber = 'sn34087' OR serialnumber 'hpk2679');

So basically I would like to have the ability to have multiple OR statements and the operand could be 'contains' or 'not contains' as that would probably work better than "equal".

Bug report

The DatePicker's popup has a CSS min-height property set that causes it to sometimes have an empty blank space at the bottom.

Reproduction of the problem

1. Open the DatePicker Demo
2. Expand the monthpicker

Review another occurence.

Expected/desired behavior

There should be a blank space in the DatePicker's popup.
