When SchedulerGroupOrientation is set to vertical, increasing the height of the `SchedulerResourceGroupHeader` breaks the rendering of the Scheduler cells, which causes misalignment of the appointments. In my scenario, I want to have a Button and an Icon in the group header cell.

Reproduction example: https://blazorrepl.telerik.com/wJElGYvF02XSsN6j42

The value in a numeric textbox cannot be changed for negative numerbes unless you erase all the text and restart.

Description

File data is not available in the Upload's OnSuccess event.

Regression in version 9.0.0 introduced with the addition of the chunk upload functionality.

https://github.com/telerik/blazor/blob/master/js/telerik-blazor/src/upload/upload.ts#L282-L288

Steps To Reproduce

1. Attach a handler to the OnSuccess event:

<TelerikUpload SaveUrl="/api/upload/save"
               RemoveUrl="/api/upload/remove"
               OnSuccess="@OnSuccessHandler" />

@code {
    async Task OnSuccessHandler(UploadSuccessEventArgs e)
    {
        foreach (var file in e.Files)
        {
            Console.WriteLine($"Name = {file.Name}, Size = {file.Size}, Extension = {file.Extension}");
        }

        StateHasChanged();
    }
}

2. Upload a file and try to access its Name, Size, and Extension properties in the event handler.

Actual Behavior

The properties have their default values (null for Name and Extension and 0 for Size).

Expected Behavior

The actual file data is accessible in the OnSuccess event handler.

Browser

When clicking on a tab to drag it to reorder, it will process the tab change as soon as the tab is clicked to start a drag operation.  Preferably, we'd like the tab select action to only happen on a mouseup instead of a mousedown (and cancelled on drag.)  This is a reproduction in the REPL: https://blazorrepl.telerik.com/mAayPpGb59GjWvUT47.  But it so simple that you probably don't need it. This is the main razor file:

When the HTML is rendering, I don't see the Id. I need it for QA Test automation.

<TelerikButtonGroup SelectionMode="ButtonGroupSelectionMode.Single" >
     <ButtonGroupToggleButton Class="pg-toggle-item"
                             Id="ToggleButton_Block" Selected="@item.IsBlockDomain">Decsription1</ButtonGroupToggleButton>
     <ButtonGroupToggleButton Class="pg-toggle-item"
                              Id="ToggleButton_Allow" Selected="@item.IsAllowDomain">Decsription2</ButtonGroupToggleButton>
     <ButtonGroupToggleButton Class="pg-toggle-item"
                              Id="ToggleButton_Cookieblock" Selected="@item.IsBlockCookies">    Decsription3 </ButtonGroupToggleButton>
 </TelerikButtonGroup>

Description

When the dropdown is open, the button's aria-controls attribute references a value that matches the popup's data-id, not its actual id. Since aria-controls must point to an element's id, the attribute is invalid and no element in the DOM matches the reference, breaking the accessible relationship between the button and its popup. 

Button renders:

aria-controls="50dc5df2-b83e-41bd-8c34-98470aba77c6"

Popup element has:

data-id="50dc5df2-b83e-41bd-8c34-98470aba77c6"
id="8630d4e4-2f22-4eaf-b96c-7cae113b70ed"

Steps to Reproduce

1. Add a TelerikDropDownButton using the standard Telerik example (source below).
2. Open the dropdown and inspect the HTML or run a Lighthouse audit.

<TelerikDropDownButton Icon="@SvgIcon.Share" OnClick="@(()=>OnItemClick("Primary"))">
    <DropDownButtonContent>Share</DropDownButtonContent>
    <DropDownButtonItems>
        <DropDownButtonItem Icon="@SvgIcon.Facebook" OnClick="@(()=>OnItemClick("Facebook"))">Facebook</DropDownButtonItem>
        <DropDownButtonItem Icon="@SvgIcon.Twitter" OnClick="@(()=>OnItemClick("Twitter"))">Twitter</DropDownButtonItem>
        <DropDownButtonItem Icon="@SvgIcon.Linkedin" OnClick="@(()=>OnItemClick("Linkedin"))">Linkedin</DropDownButtonItem>
        <DropDownButtonItem Icon="@SvgIcon.Reddit" OnClick="@(()=>OnItemClick("Reddit"))">Reddit</DropDownButtonItem>
    </DropDownButtonItems>
</TelerikDropDownButton>

When ActiveTabId is null, the TabStrip selects the first tab automatically, but does not render its content.

<TelerikTabStrip @bind-ActiveTabId="@TabStripActiveTabId">
    <TabStripTab Title="First" Id="t1">
        First tab content.
    </TabStripTab>
    <TabStripTab Title="Second" Id="t2">
        Second tab content.
    </TabStripTab>
    <TabStripTab Title="Third" Id="t3">
        Third tab content.
    </TabStripTab>
</TelerikTabStrip>

@code {
    private string? TabStripActiveTabId { get; set; }
}

There is an undocumented breaking change in the selection behavior of the v13.0.0 TreeView component that prevents us from upgrading from v12.3.0.

In v12.3.0, selecting a TreeView checkbox does change the TreeView item selection or trigger the selection change events. In v13.0.0, checking an item does also change the selection. The v12.3.0 behavior is important for our implementation because selecting a TreeView item in our application fetches data from a database and we do not want the performance overhead of those calls when checking an item---we want the user to be able to select multiple items and only then explicitly fetch the data for all of them.

I've created a minimal example here: https://blazorrepl.telerik.com/cqYdEePd40Zq3ava43. You can see the behavior differences when switching between versions.

Please let me know if there's any additional information we can provide. A workaround to this behavior would be appreciated. Thank you!

Currently, only the "Download" option has an icon and this is not consistent:

OnChange and OnBlur event for editors (TelerikTextBox, NumericTextBox, and others) is not fired in InCell edit mode with Tab key.

Hello,

Currently the Telerik diagram component looks very promising but lacks the option to better control what's shown inside each DiagramShape (Block, node). Wouldn't it be possible to allow a Template renderfragment inside of these shapes so we can fully control what's shown? This way we can build more complex diagrams with images, text, buttons inside.

Set the PdfViewer document (data) value to null. As a result, an endless loader will appear.

A possible workaround for the time being is to re-initialize the component after clearing the file: https://blazorrepl.telerik.com/cHYwQola24zzBOAd02.

The Tooltip component throws a JavaScript error when the user opens an adaptive dropdown component and tries to interact with it:

Uncaught TypeError: popup.isParent is not a function

Here is a test page. Open the DropDownList on a narrow screen and click on the adaptive ActionSheet.

<TelerikButton Class="tooltip-target" Title="Telerik Tooltip">Button</TelerikButton>

<TelerikDropDownList Data="@ListItems"
                     @bind-Value="@SelectedValue"
                     TextField="@nameof(ListItem.Text)"
                     ValueField="@nameof(ListItem.Id)"
                     AdaptiveMode="@AdaptiveMode.Auto"
                     Width="300px" />
<TelerikTooltip TargetSelector=".tooltip-target"
                ShowOn="@TooltipShowEvent.Hover" />

@code {
    private List<ListItem> ListItems { get; set; } = new();

    private int SelectedValue { get; set; } = 3;

    protected override void OnInitialized()
    {
        ListItems = new List<ListItem>();
        for (int i = 1; i <= 5; i++)
        {
            ListItems.Add(new ListItem()
            {
                Id = i,
                Text = $"Item {i}",
                Category = $"Category {i % 6 + 1}"
            });
        }
        base.OnInitialized();
    }

    public class ListItem
    {
        public int Id { get; set; }
        public string Text { get; set; } = string.Empty;
        public string Category { get; set; } = string.Empty;
    }
}
