Greetings,

I find input adornments very useful. However I noticed that when I click them, the control doesn't get the focus. E.g., with this code:

    <TelerikTextBox>
        <TextBoxPrefixTemplate>
            First name
        </TextBoxPrefixTemplate>
    </TelerikTextBox>

Clicking on First name doesn't do anything. I would expect the control to be focused when I do that.

You will find an image in attachment showing a green area that, when clicked, brings focus on the textbox. Input adornment is in dark gray. I'm using it as a label for the control but even if it was simply an icon, it would be strange to not be able to focus on the control when clicking it.

Below issue was submitted 6 days ago. Currently developers are disabling/uninstalling Telerik extensions. I don't see any relies from Telerik so submitting another bug report hoping you'll reply to this one.

Please fix it!!!

Telerik UI for Blazor 3.6.0 breaks intellisense/typing in Visual Studio 2022 Version 17.3.4

Trying to group by some nullable column. Expanding the group returns the entire dataset instead of only these rows with value == null.

Use case: Some users can not be assigned to any Team. Want to group by Teams and see users not assigned to any Team.

Steps to reproduce:

• Using Virtual Scrolling with OnRead method.
• Have a nullable column e.g. string?.
• Trying to group by this column gives unexpected results.

Expected results:

Expanding the group by not assigning Teams returns only these users what doesn't have any teams by applying filtering.

Actual results:

 Expanding the group by not assigning Teams returns all users without filtering.

Code:

@using Telerik.DataSource
@using Telerik.DataSource.Extensions

Scroll through the groups or expand them to load their data on demand

<TelerikGrid TItem="@object"
             LoadGroupsOnDemand="true"
             Groupable="true"

Changing page size triggers multiple read requests.

Need feature parity in the Blazor rich text editor similar to the Angular rich text editor.  Need access to add custom schema elements and tag highlighted text with those new schema elements.

https://www.telerik.com/kendo-angular-ui/components/editor/schema/

currently am able to do this with custom Marks in the angular version.

Hi

Telerik Autocomplete does not have a ValueTemplate.

Mostly the Value is an Id, which in most examples does not make sense to be displayed to the User when selected.

Kind regards

Nicolas

The default `ButtonType` looks for any matching form and triggers validation and submission of the form.
This can very quickly lead to unintended behaviour.

The default should be a regular button that does not invoke any additional functions.

It seems I'm missing Height, MinHeight, and MaxHeight settings here. 

When user click into the date picker textbox, the placeholder value is changed to what's set to "format" for the date picker. For example, I have the following configured:

<TelerikTimePicker Placeholder="dd/mm/yyyy" Format="dd/MM/yyyy"></TelerikTimePicker>

The control will display "dd/mm/yyy" in the textbox, however, when user click into the textbox, the placeholder value changes to "dd/MM/yyyy".

The Visible parameter removes the underlying render fragment when set to false.

Please expose APIs (maybe Show/Hide methods) to keep the DOM in tree but only modify visibility / display CSS attributes to hide/show the telerik window element. This would allow developer to retain content / state of the window which may need to be displayed very frequently.

On Blazor filter field parameters, please consider adding

1/ Group options, eg using demo sample fields drop down looks like this

Id
Quantity
Freight
Country
Ship to
Ship Address

but it would be useful to allow groping fields by common categories?

Group-1
-Id
-Quantity
-Freight
Group-2
-Country
-Ship to
-Ship Address

2/ Related, can you also add sort index for group and fields so they can be sorted by index rather than field name. Sometimes groups and fields require different order that is not always alphanumerical and may change order based on other selections.

3/ Maybe consider feature parity with filter field options here querybuilder

I would like to be able to change the multiselect tags, mainly colors, forground and background, of both dropdown elements (shown in list) and selected values shown in textbox like the image bellow

On Blazor Filter, please consider option to drag and drop rules to re-order the rules. It's a common user request that when creating complex rules that user has ability to move rules around without having to delete and create again. User loses information and data when rules are deleted and can be difficult to relocate in long drop downs.

Ability to drag and drop move of existing rules would improve user experience. Any change to GUI should also reflect in updated FilterDescriptor.

===

ADMIN EDIT

===

The order of the filter rules in one group does not make a difference for the FilterDescriptor. Thus, the current request applies to dragging filter rules from one group to another.

To be considered for implementation as a standalone component or feature of ListView, for example.

The purpose of such component is to provide option for users to reveal contextual actions when they do a swipe gesture on mobile devices. The swiping direction to consider is left and right (up and down are out of scope).

List of possible functionalities for consideration:

• Option to configure menu actions on left and right swipe gesture and define which menu actions will be shown on left and which on right swipe
• Option to use icons in menu items 
• Additional customization options for menu items - color, images, custom content
• Configurable number of items for the menu, plus option to define more
• Confirmation of actions (needed for actions related to deleting/removing data)

Please feel free to provide any feedback and share your suggestions on desired functionalities.

Just Moving from Ajax UI to Blazor

Used the search box a lot - multi-columns, had first match as typed toward an item,filtering, a click return the item selected

Wonderful

please can we have a blazor version?

Hi. VS 2022 version 17.2.4, C#, Windows 11

I thought I'd have a look at blazor and selected the Telerik version in the new projects window and ran through the wizard.

I selected the dashboard look, .net 6, teleric UI for blazor 3.4.0 (Dev) and to enable localization, which is what I assume to be the cause of the following error message. There were no other hints and as I've never tried blazor or telerik for blazor I don't know if there's anything missing from the solution. If I ran another wizard without localization there was no error.

An error occurred while running the wizard.

Error executing custom action Telerik.Blazor.VSX.Actions.CopyBlazorLocalizationResourcesAction: System.Collections.Generic.KeyNotFoundException: The given key was not present in the dictionary.
