Hallo,

i want to Render PDF Files with the PDF Viewer Component.

The Data of the PDF is already fetched from the API when the PDF-Viewer starts Rendering the Loading animation appears and freezes.

After a few Seconds the PDF will be Rendered.

The size of the PDF File is about 5MB.

On Hierarchy grids with Inline edit mode, I noticed that if a row is currently being edited and I try to expand the row to show the child grid an exception is thrown: "Error: System.InvalidOperationException: TelerikValidationComponent requires a cascading parameter of type EditContext. You can use Telerik.Blazor.Components.TelerikValidationTooltip`1[System.String] inside a EditForm or TelerikForm".

The problem stems from a validation tool inside the Grid EditorTemplate.

If you are zooming a page containing a DateTimePicker with "AdaptiveMode" set to "AdaptiveMode.Auto", the application crashes occasionally with the error:

Microsoft.JSInterop.JSException: Cannot read properties of null (reading 'addEventListener')
TypeError: Cannot read properties of null (reading 'addEventListener')

The more adaptive DateTimePicker instances the page contains, the more likely the error is to occur.

I have a ComboBox/DropDownList that gets data from a remote service, using virtualization. When the PageSize property is big enough (in my case 20), I have issues scrolling up the selection box dropdown list. I'm trying to scroll but then resets to the currently selected item making it almost impossible to scroll up. You can use your own demo examples to replicate this issue.

To reproduce the issue, try the ComboBox - Virtualization, in Telerik REPL (Demo), change the PageSize from 10 to 20. Open the dropdown and select an item. Then, open again the dropdown and scroll slowly up.

If you open a child menu via the keyboard, you can then hover over another parent and open a second submenu. The problem can be reproduced in the live demo.

The issue targets the Menu component as well.

The issue is reproducible when the `AllowCustom` parameter is set to `true`.
Typing rapidly in the input field of the MultiColumnComboBox component causes the entered text to blink. Also, some of the inserted symbols are cleared.

Reproduction (if bug)

Open this demo: https://demos.telerik.com/blazor-ui/multicolumncombobox/custom-values

Try to input text rapidly into the input field.

When the component's Adaptive mode is set to Auto, the Date & Time buttons in the popup are not rendered.

Here is a CSS workaround that hides the titlebar in adaptive mode so that the buttons are present:

<style>
    .k-actionsheet-titlebar.k-text-center{
        display: none;
    }
</style>

<TelerikDateTimePicker @bind-Value="@SelectedTime"
                        Format="MM/dd/yyyy hh:ss"
                        ShowWeekNumbers="true"
                        Id="selected-date"
                        AdaptiveMode="Telerik.Blazor.AdaptiveMode.Auto">
</TelerikDateTimePicker>

@code {
    private DateTime? SelectedTime = DateTime.Now;
}

</AdminEdit>

The appointments at the start of the day seem accurate. If you scroll down, the position of the appointments does not line up with the grid line for the hour that it starts at or ends at. The issue can be observed in the live demo.

To reproduce the problem, hover over the last value of the series. While the Tooltip enters, it causes horizontal and vertical scroll and flickers. Then, it is positioned correctly.

The issue is better observed if you increase the transition speed of the Tooltip wrapper.

A possible workaround for the time being is to alter or stop the Tooltip animation with CSS. Here is a runnable sample demonstrating the approach: https://blazorrepl.telerik.com/QnEjvIOC04hXA6W709

If the PdfViewer is initialized with a default document, the display performance of this document will be a lot worse, compared to PDF documents that are loaded programmatically after the component is already on the web page.

When I tried to convert a project with Microsoft Identity Platform:

Then I hit the following error message:

Hi

The reset button is not working when we use the column template with the Telerik grid. How to solve this problem? Can you please send it example for reference?

Thanks

When initial grouping is set through the state, the GroupFooterTemplate does not render. One has to perform some action for refreshing the Grid in order to display the template - for example, collapsing/expanding a group.

For reference, the GroupHeaderTemplate renders correctly.

The GroupFooterTemplate renders with a delay after the Grid. A possible workaround for the time being is to refresh the Grid after it has been initialized to ensure the GroupFooterTemplate will be displayed.

Hello,

after selecting a block of text in your editor and perform some block operation (for instance - change font size, name, ..) the original selection is lost. Would it be possible to keep that selection please?

Very thanks.
