Here is a TelerikForm with a FormItem (1) for a boolean field. Another FormItem (2) should render, depending on the boolean field (1). This does not work with a TelerikForm, but works with a standard EditForm.

The workaround for a TelerikForm is to use a FormItem Template with a TelerikCheckBox. This is demonstrated below as well.

<EditForm Model="@_data">
    <label>Condition 1 (InputCheckbox):</label>
    <InputCheckbox @bind-Value="@_data.Value1" />
    <br />
    @if (_data.Value1)
    {
        <label>Result 2</label>
        <InputCheckbox DisplayName="Result 2:" @bind-Value="@_data.Value2"></InputCheckbox>
    }
</EditForm>

<h1>TelerikForm</h1>

<TelerikForm Model="@_data">
    <FormItems>
        <FormItem LabelText="Condition 1 (FormItem):" Field="@nameof(_data.Value1)"></FormItem>
        <FormItem>
            <Template>
                <label for="x">Condition 1 (TelerikCheckBox):</label>
                <br />
                <TelerikCheckBox Id="x" @bind-Value="_data.Value1" />
            </Template>
        </FormItem>
        @if (_data.Value1)
        {
            <FormItem LabelText="Result 2:" Field="@nameof(_data.Value2)"></FormItem>
        }
    </FormItems>
</TelerikForm>

@code {
    private ExampleDto _data { get; set; } = new ExampleDto();

    public class ExampleDto
    {
        public string TextValue { get; set; }
        public bool Value1 { get; set; }
        public bool Value2 { get; set; }
    }
}

When Grid is nested in a Window, pressing Escape key will bubble to the Window causing it to close during edit operation of the Grid.

1. Go to https://blazorrepl.telerik.com/mQaUcSlP59yrfqmM16 
2. Trigger Grid's keyboard navigation.
3. Press Escape(whether it is to close an Editor, or not).
4. Observe Window will close.

If my browser culture is set to Swedish, I can no longer tab through multiple ComboBoxes.

<AdminEdit>

You can manually add the TabIndex parameter to each ComboBox and set their values to non-negative integers.

In addition to the PdfProcessing, I would also like to be able to use a component to show PDFs to my users.

ADMIN EDIT

For the time being, a workaround could be to wrap a JS widget, an example is available in this sample project, see the MyKendoPdfViewer.razor component and make sure to include the relevant JS libraries.

Another approach could be a simple iframe that points to a handler that will return the PDF with content-disposition:inline. Most modern browsers will render this inline.

Per WAI-ARIA 1.2, the "aria-level" attribute, if present, "is an integer greater than or equal to 1".

However, Blazor TreeView uses 0-indexing for the attribute which means that the root item has an invalid (and ignored) aria-level property. This is problematic because the browser will infer the level from the DOM nesting for the root item, but then use aria-level for all other sub-trees, leading to inconsistent levels (in the demo, the level goes 2 > 1 > 2).

How to get only the year and date in the Gantt Chart Tooltip template? The DataAttribute is not a valid date string.

<TooltipTemplate>
     <h4>@(((TooltipTemplateContext)context).Title)</h4>
     <h5>Start: @(((TooltipTemplateContext)context).DataAttributes["start"])</h5>
     <h5>End: @(((TooltipTemplateContext)context).DataAttributes["end"])</h5>

</TooltipTemplate>

I would like to be able to configure the auto-tab behavior so that the DateInput only tabs when user type '/' (i.e. disable smart auto-tabbing).

month/day/year 

Expected UX:  3/3/2022
Example: https://demos.telerik.com/kendo-ui/dateinput/index 

Current UX: 332022
Example: https://demos.telerik.com/blazor-ui/dateinput/overview 

Blazor load on demand (as users keys in) combo-box with multi column

Where there is a spacer inside the ToolBar or when there are no items that should be hidden anymore, the overflow anchor overlay with the other items.

It would be nice to be able to configure a show/hide animation for windows.

ADMIN EDIT: This might include a form of a Shown event so that you could know when the content is rendered and available to, for example, focus a button or input. For more details see here

How can I set the tooltip to show/hide programmatically? right not it only supports hover or click show action.

---

ADMIN EDIT

You can Follow a way to hide the tooltip programmatically here: https://feedback.telerik.com/blazor/1476364-close-tooltip-via-method.

You can find a way to hack the show event by triggering a JS click in this KB article: https://docs.telerik.com/blazor-ui/knowledge-base/common-validation-error-in-tooltip.

Here is an example that shows how you can trigger the tooltip to show for a particular target:

@inject IJSRuntime _js

<script suppress-error="BL9992">
    function triggerTooltip(index, selector, showOnClick) {
        var targets = document.querySelectorAll(selector);
        if (targets && targets.length >= index) {
            var desiredTarget = targets[index];//feel free to get the desired target in any other way
            setTimeout(function () {
                var evt = document.createEvent('MouseEvent');
                var evtToSimulate = showOnClick ? "click" : "mouseenter";
                evt.initEvent(evtToSimulate, true, false);
                desiredTarget.dispatchEvent(evt);
            }, 20);
        }
    }
</script>

<TelerikButton OnClick="@( async () => await TriggerTooltip(0) )">Trigger tooltip for the first target</TelerikButton>
<TelerikButton OnClick="@( async () => await TriggerTooltip(1) )">Trigger tooltip for the SECOND target</TelerikButton>

<TelerikTooltip TargetSelector="@ttipTargetSelector" ShowOn="@ShowOnSetting">
</TelerikTooltip>



<p id="my-targets">
    <strong title="what is 'lorem ipsum'?">lorem</strong>
    ipsum dolor
    <strong title="is this a real word?">sit</strong>
    amet.
</p>

@code{
    string ttipTargetSelector = "p#my-targets [title]";
    TooltipShowEvent ShowOnSetting { get; set; } = TooltipShowEvent.Click;
    async Task TriggerTooltip(int targetIndex)
    {
        await _js.InvokeVoidAsync("triggerTooltip", 
                targetIndex, 
                ttipTargetSelector, 
                ShowOnSetting == TooltipShowEvent.Click ? true : false
             );
    }
}

<TelerikScheduler AllowCreate="@Editing" AllowDelete="@Editing" AllowUpdate="@Editing" OnDelete="@AppointmentDelete" OnEdit="@AppointmentEdit" OnUpdate="AppointmentUpdate"  Data=…

The above line breaks only with AllowUpdate.

I default Editing false, then toggle it true in the hosting component and do a InvokeAsync(StateHasChanged). 

The result is I can create and delete, but while the appointment hover cursor changes to the hand or arrows and I can see the handlebars to resize the appointment, I'm not able to update the appointment until I switch the SchedulerView. After switching SchedulerView updating works as expected.

Is it possible to drop dropDownList from outside, for example after its data has been changed, without clicking on it ?

ADMIN EDIT:

This feature is also applicable to ComboBox, AutoComplete, Multiselect, Date and Time Pickers components.

Add "OnOpen" event that fires when the DateTimePicker  button is clicked but before the DateTimePicker  dropdown is shown

=============

ADMIN EDIT

=============

You can currently achieve the desired behavior by wrapping the DateTimePicker in a container (for example span), add a handler on the on-click event of the span to catch the click event and perform the desired actions in that handler.

<span class="datetimepicker-span" @onclick="@OnOpenHandler">
    <TelerikDateTimePicker Class="my-date-time-picker" Value="@selectedTime"
                           Format="dd MMM yyyy HH:mm:ss" Width="250px"></TelerikDateTimePicker>
</span>

@code {
    public DateTime? selectedTime { get; set; }

    public bool isOpened { get; set; } = false;

    public void  OnOpenHandler()
    {
        isOpened = !isOpened;

        if (isOpened)
        {
            Console.WriteLine("DateTimePicker was opened.");
        }
        else
        {
            Console.WriteLine("DateTimePicker was closed.");
        }
    }
}

I set the GridColumn DisplayFormat="{0: yyyy-MM-dd}" and the data reflects that format. The default filter control doesn't. How can I make the control do that?

---

ADMIN EDIT

For the time being, the way to affect the filter behavior is through a custom filter template. The format for date pickers and numeric textboxes comes from the app culture settings (see more here). You may also want to Follow this idea for easier selection of a default filter operator and limiting the filter operators choices.
