Telerik UI for ASP.NET MVC versioning feedback

We need your feedback, because we are considering changes in the release approach for Telerik UI for ASP.NET MVC. Please provide your feedback in the comments section below:

1. Is it hard to understand the version numbers of our releases? If yes, what makes them hard to understand them?

2. Would semantic versioning (SemVer) of our releases make it easier to understand our version numbers and what's behind them?

3. If we go with SemVer, we might need to start with version 3000.0.0 as we currently use 2022.x.x. Please share your thoughts about this approach and ideas for what number versioning would work best for you.

Datasource request fires twice on MultiSelect

I have a simple multiselect like so:

@(Html.Kendo().MultiSelectFor(x => x.CourseId)

.DataValueField("Id")

.DataTextField("Name")

.Placeholder("Select Course...")

.ClearButton(false)

.DataSource(source =>

{

source.Read(read =>

{

read.Action("GetCourseCodeList", "Home");

})

.ServerFiltering(true);

})

.MaxSelectedItems(1)

.HtmlAttributes(new { @class = "" }))

When I enter text, the search is submitted once with the text entered, then a second time with the Placeholder text, or if no Placeholder, with empty string.

public JsonResult GetCourseCodeList(string text, int categoryId=0)

{

var items = _courseData.Where(x =>

x.Name.Contains(text) &&

(categoryId == 0 || x.CategoryId == categoryId)).OrderBy(x => x.Name).ToList();

var userinput = text;

var result = new JsonResult

{

JsonRequestBehavior = JsonRequestBehavior.AllowGet,

Data = items

};

return result;

}

A sample project replicating the issue is here : https://github.com/SteveWortho/TLCKendoTest

It must be something simple I am doing wrong - any advice appreciated.

Using;

VS2017 Pro Version 15.5.1

KendoUI MVC 2017.3.1026

Chrome Version 63.0.3239.132 or Microsoft Edge or FireFox. Issue is repeatable.

So I must be firing the onChange event a second time with some of this configuration maybe?

But it is such a simple example.

Thanks in advance,

Steve

Autofocus Kendo Date Picker on button click Inside Kendo Grid

Hi,

I have a Kendo Grid and its first column is a Datetime and Its a Kendo DatePicker.

When the user click on Add new record button then the 1st cell which is a date picker should be auto focus.

Note: When the user click on Add new record button then we are sorting the grid in ascending order so that the new row should appear on the top, which is working fine but the 1st cell of the newly created row a Kendo Date picker in not in focus.

But when the user click on the first cell of the newly created row, then it opens the datepicker to allow user to select a date.

My requirement is when i am clicking the Add new record button then
1. It should sort in ascending order (Which is working now)

2. The 1st cell of the Kendo Datepicker should auto focus like the above screenshot.

ClientTemplate method not firing for a Boolean field in Kendo grid

Hi,

I have a kendo grid, where i am creating a new empty row while loading the grid.

The grid has a Boolean filed which is a mandatory field. so when we want to enter the row values then it should call the CheckIsPublicFund(data) method and if the user is not selecting the Boolean field then it should add that value to false.

The problem is when selecting the Boolean value then its not firing the CheckIsPublicFund(data) method.

Copy Excel record to Kendo grid paste performance issue

Hi,

I am working on a kendo grid, where user can copy records from the excel and paste in the kendo grid.

But when we copy more than 50 records from the excel and paste in the kendo grid then it is taking some time.

Can we increase the performance while pasting in to the Kendo grid or is it possible we can provide a progress bar or something to show to the user when the user paste more than 50 record.

Add HTML Link in Kendo Chart CategoryAxis or ValueAxis Label

Hi,

I'm using Kendo UI for ASP.NET MVC and I need to add an HTML link (<a href="...">) inside the CategoryAxis.Labels.Template or the ValueAxis.Labels.Template of a Bar Chart. Here is a simplified version of my code:

@(Html.Kendo().Chart()
    .Name("productsChart")
    .Series(series =>
    {
        series.Bar(new[] { 100, 200, 300 }).Name("Sales");
    })
    .CategoryAxis(axis => axis
        .Categories("Product A", "Product B", "Product C")
        .Labels(labels => labels
            .Template("<a href='https://example.com/product/#= value #' target='_blank'>#= value #</a>")
        )
    )
)

However, the chart only displays the raw text of the <a> tag instead of rendering it as a clickable HTML link. I understand this may be due to the chart rendering via SVG and not supporting HTML natively in axis labels.

Is there any workaround or supported way to:

Render actual HTML in axis labels?

Enable links or interactive elements within axis labels?

I’ve already considered using tooltips and seriesClick events as alternatives, but my goal is to have direct clickable links inside the axis labels themselves.

Thanks for your help!

'IEnumerable' does not contain a definition for 'ToDataSourceResult'

Hello,

I created new project using Telerik wizard. I am trying to populate a grid with data-source using ajax but I am failing at using ToDataSourceResult. I am getting error

'IEnumerable<Person>' does not contain a definition for 'ToDataSourceResult' and the best extension method overload 'QueryableExtensions.ToDataSourceResult(DataTable, DataSourceRequest)' requires a receiver of type 'System.Data.DataTable'

I compared it with project created by Telerik wizard for page with grid and still don't see why this error occurs.

Please see attached figure. It is screenshot taken from HomeController where I am trying to get data-source from IEnumerable.

Kendo MVC Grid Transpose Columns using HTML Helper

Hi,

I'm trying to figure out how to transpose columns in a Kendo Grid using the Html helper.

I see that there's this small piece of documentation for jQuery (https://docs.telerik.com/kendo-ui/knowledge-base/transposed-grid), but would ideally like to do it on the helper itself.

Is anyone aware of how to do this?

Any help is much appreciated!
