If the TextArea component is used within an EditorTemplate of a grid column, edit mode is always closed upon hitting ENTER.  The thing is that I'm using the TextArea to allow the user to input several lines.  Upon Enter the user wants to move to a new line within the TextArea and not to finish the edit mode.

Regards,

René

For the time being I can offer using the popup editing or a custom external edit form (inline or popup).

Another workaround would be to stop the keydown event propagation so the grid/treelist cannot consume it and close the cell:

        <TreeListColumn Field="EmailAddress" Width="220px">
            <EditorTemplate>
                @{
                    CurrentlyEditedEmployee = context as Employee;
                    <div @onkeydown:stopPropagation="true">
                        <TelerikTextArea @bind-Value="@CurrentlyEditedEmployee.EmailAddress"></TelerikTextArea>
                    </div>
                }
            </EditorTemplate>
        </TreeListColumn>

It is possible that the grid might stop handling Enter when editor templates are present so you can use the events from the custom editor as desired to invoke the save operation. This could happen through the following request: https://feedback.telerik.com/blazor/1493770-ability-to-prevent-multiple-calls-of-async-updatehandler-when-pressing-enter-in-incell-edit-mode. With or without it, it is highly likely that the approach of preventing the event propagation is the correct one because the grid cannot know what the editor template contains and handle events differently based on that.

The Theme Builder contains a really nice looking Popover control, and I was a bit disappointed to discover that this doesn't seem to be documented or supported in UI for Blazor.

I realize I can probably use the Tooltip to achieve a similar effect, with two caveats:

1. Tooltip requires of substantial CSS hacking to appear as the Popover control.
2. The Popover closes on an explicit event, whereas Tooltip closes when it loses focus.

Is there any chance a Popover control is planned for a future release?

In many cases users need to be able to specify a number which is easily visualized using a horizontal slider.
This allows the user to easily move the point to their desired location.

It can be helpful to allow this to also be constrained using a forced range selection.

I have been trying to improve my Lighthouse score with Google and one of the items it is tagging is the "telerik-blazor.js" file.  I have seen new practices where the JavaScript is imported as needed, see this article here from Microsoft.

Can you please consider this in the future?

Telerik edit: A possible workaround is to build the Telerik JavaScript file without some of the components that you don't need.

Hi

Passwords are not yet supported. There is a DataAnotations Datatype for that. So technically this is possible and should not be a big deal. Almost all apps have a password entry somewhere. 

Example:

    class LoginModel
    {
        [Required]
        [Display(Name = "User Name")]
        public string UserName { get; set; }

        [Required]
        [DataType(DataType.Password)]
        [Display(Name = "Password")]
        public string Password { get; set; }
    }

Annoying because then you have to do the form fields all manually because of the password.

Thanks for considering.

Best regards, Michael

Greetings!

Since the focus events are natively supported by blazor, could they be implemented in the input controls? Workarounds via JS are possible but they create a lot of redundant and cluttered code around the code base. OnChange/ValueChange only fire when the value has changed. Though, we have a lot of scenarios where we need the focus events when a value did not change.

Unexpected scroll behaviour is seen after selecting an item in a DropDownList/Multiselect with a scroll mode set to virtualise. We are unable to easily scroll upwards using the scroll bar in the control or using a mouse/trackpad. The scroll position immediately snaps back to the selected item. Sometimes we are able 'escape' this by rapidly scrolling but this does not feel like intended behaviour.

Downward scrolling seems okay and using the keyboard arrow keys also seems unaffected. This is reproducible on the demo page: Blazor DropDownList - Virtualization - Telerik UI for Blazor and https://docs.telerik.com/blazor-ui/components/multiselect/virtualization.

Reproduction steps on Chrome:

1. Navigate to demo page and render local example preview
2. Select item "Name 27"
3. try to scroll up with the arrow buttons on the scrollbar or the mouse wheel

Minimal reproducible example: Blazor MultiSelect - Virtualization - Telerik UI for Blazor

    <input class="form-control" readonly="@(!EditMode)" type="text" @bind="@FormField.TextValue"/>

I couldn't find a way to change the default AnimationDuration of the combobox's popup. Personally, I find the default AnimationDuration set at 300ms way too high.

I'd like a way to change it either per-component, by setting animation properties on them when appropriate, or globally, by configuring it in Startup.cs or on TelerikRootComponent perhaps. I've no idea how this should work.

ADMIN EDIT

Here is a way to change the animation of the dropdown per component - through the PopupClass (note that the popup class may move to the topmost element of the popup in a future version, if this stops working, inspect the rendering to see where the custom class is and how to cascade through it):

<style>
    .fast-animation.k-popup.k-reset {
        transition-duration: 100ms !important;
    }

    .slow-animation.k-popup.k-reset {
        transition-duration: 1000ms !important;
    }

    .no-animation.k-popup.k-reset {
        transition: none !important;
    }
</style>



<TelerikComboBox PopupClass="fast-animation"
                 Data="@myComboData"
                 TextField="MyTextField"
                 ValueField="MyValueField"
                 @bind-Value="selectedValue"
                 Placeholder="Fast animation"
                 ClearButton="true" Filterable="true">
</TelerikComboBox>

<TelerikDropDownList PopupClass="no-animation"
                     Data="@myComboData"
                     TextField="MyTextField"
                     ValueField="MyValueField"
                     @bind-Value="selectedValue"
                     DefaultText="No Animation">
</TelerikDropDownList>

<TelerikDatePicker PopupClass="slow-animation" @bind-Value="@SelectedDate"></TelerikDatePicker>

@code {

    IEnumerable<MyDdlModel> myComboData = Enumerable.Range(1, 20).Select(x => new MyDdlModel { MyTextField = "item " + x, MyValueField = x });
    DateTime SelectedDate { get; set; } = DateTime.Now;
    int selectedValue { get; set; } 
    public class MyDdlModel
    {
        public int MyValueField { get; set; }
        public string MyTextField { get; set; }
    }
}

Hi,

is it possible to add control of vertical timeline like this (https://antblazor.com/en-US/components/timeline) with extra features like:

• adding new items with button on top
• inline edit
• item selection
• item actions

I also attached image of what i build based on control from link above, I would like to implement something similar with Telerik.

Maybe you can recommend some other controls to replace it with?

Thank you :)

It seems like Blazor on the server-side will be re-branded as Razor Components. Will Telerik support it?

Since upgrading from 3.8 to 4.4 (including all new css) created dialogs from DialogFactory are sometimes behind an already opened modal window.
The reason for this seems to be an incorrectly, automatically calculated z-index of 10003 when the open dialog has 10006.
This does not always happen, there are scenarios where the first created dialog works fine, and the next called in the same method suddenly is behind the dialog, thus the error seems to be in telerik and not our side.

We could not yet find a proper workaround apart from creating custom dialogs.
