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.

Hi!

The ListView is breaking my web application, and I cannot make head or tail of the reason:

An unhandled exception occurred while processing the request.

Kendo.Mvc.UI.ListView<T>.VerifySettings()

Also, you demos for the ListView are broken and the browser tab crashed after a while.

I need an urgent fix, as this is affecting the live application.

In our UI for ASP.NET Core R3 2020 (2020.3.915) release, the Column menu message of unsticking a column is "null".

This bug will be resolved in our next official release.

In the meantime, as a workaround, manually set the Unstick Column menu message:

I have a simple test page that has a Chart and a PDF Viewer. I can not get both to work at the same time without getting a license error.

Below is how I  have tried loading the Kendo library at the top of the page. For the chart, I need to load it as a script for it to work. For the PDF Viewer I need to load it as a module. But loading both always breaks the license. I have tried version combinations (see below) 

How do I get a chart on the same page as the PDF Viewer and have the license work?

Scenario 1:

<script src="~/Portal/kendo/kendo.all.min.js" ></script>
<script src="~/Portal/kendo/kendo.aspnetmvc.min.js" ></script>

• Chart loads correctly
• PDF Viewer fails to load
• The license loads correctly

 Scenario 2:

<script src="~/Portal/kendo/kendo.all.min.js" type="module" ></script>
<script src="~/Portal/kendo/kendo.aspnetmvc.min.js" type="module" ></script>

• Chart fails to load
• PDF Viewer loads correctly
• The license loads correctly

Scenario 3:

<script src="~/Portal/kendo/kendo.all.min.js" ></script>
<script src="~/Portal/kendo/kendo.aspnetmvc.min.js" ></script>

<script src="~/Portal/kendo/kendo.all.min.js" type="module" ></script>
<script src="~/Portal/kendo/kendo.aspnetmvc.min.js" type="module" ></script>

• Chart loads correctly
• PDF Viewer loads correctly
• The license fails to load

Hi,

I'm trying to understand the data binding for a combo box control.

Approach 1. - Using the bind-to attribute. I added "Selected=true" to one of item in the continents data source. This is okay the control pre-selects the item correctly.

Ref https://www.telerik.com/aspnet-core-ui/documentation/html-helpers/editors/combobox/getting-started#3-select-a-default-value

    @{
        var continents = new List<SelectListItem> {
            new SelectListItem() {Text = "Africa", Value = "1"},
            new SelectListItem() {Text = "Europe", Value = "2"},
            new SelectListItem() {Text = "Asia", Value = "3"},
            new SelectListItem() {Text = "North America", Value = "4", Selected=true},
            new SelectListItem() {Text = "South America", Value = "5"},
            new SelectListItem() {Text = "Antarctica", Value = "6"},
            new SelectListItem() {Text = "Australia", Value = "7"}
        };
    }

    <h4>ComboBox:</h4>
    <kendo-combobox name="combobox1"
                    datatextfield="Text"
                    datavaluefield="Value"
                    placeholder="Select a value"
                    bind-to="continents"
                    style="width: 250px;">
    </kendo-combobox>

Approach 2. - Ajax binding. I have the same datasource as Approach 1 to return in TestController.cs. I"m expecting "North America" should be pre-selected but it's not. Is this an expected behavior by design when using Ajax binding that "Selected=true" is not appliable? The reason why I'd like to use "Selected=true" with Ajax binding is because there are some logics in a controller action that set the default value for a combo box. I don't want to use the "value" attribute. I knew using the value attribute works for sure.

Ref https://www.telerik.com/aspnet-core-ui/documentation/html-helpers/editors/combobox/binding/ajax-binding

TestController.cs

    public IActionResult Getcontinents(string payload)
    {
        var continents = new List<SelectListItem> {
            new SelectListItem() {Text = "Africa", Value = "1"},
            new SelectListItem() {Text = "Europe", Value = "2"},
            new SelectListItem() {Text = "Asia", Value = "3"},
            new SelectListItem() {Text = "North America", Value = "4", Selected=true},
            new SelectListItem() {Text = "South America", Value = "5"},
            new SelectListItem() {Text = "Antarctica", Value = "6"},
            new SelectListItem() {Text = "Australia", Value = "7"}
        };

        return Json(continents);
    }

Index.cshtml

    <kendo-combobox name="combobox2"
                    datatextfield="Text"
                    datavaluefield="Value"
                    filter="FilterType.Contains">
        <datasource server-filtering="false">
            <transport>
                <read url="/Test/Getcontinents"/>
            </transport>
        </datasource>
    </kendo-combobox>

Any insights or thoughts?

Thanks,

I'm trying to apply a class to a textbox label like so:

<kendo-textbox name="customerNameTextbox" for="@Model.Name">
<textbox-label content="Name" class="required" />
</kendo-textbox>

However, I can see in the browser development console that the label component associated with the component only has the usual k- classes applied to it:

<label class="k-label k-input-label" for="Name">Name</label>

How can I make sure my class is applied to the label?

Hi all,

Going nuts over this problem. Should be simple, and for other technologies telerik shows solutions, but can not get it to work for razor pages .net core. 

What i want is:

I have a grid that opens in a popup when editting. In the editortemplate i have a childgrid showing all possible children that can be added to this record. That is working. However, i want to multiselect in this grid without having my customers to hold down  ctrl or use a textbox. Main reason: When using a textbox, you really have to click in the textbox, clicking outsisde of it won't work. So i removed the select column (the checkboxes) and just want people to click somewhere on a row to select it and be able to click on another row without the fiorst one loosing it's selected status. The only hook i can find is the onchange event. This indeed allows me to catch the slection process. However, the previously selected items are not available any more, so i oose them. 

Anyone an idea how to do this quite simple trick?
