Hi,

Would be great if there could be a Timeline component for Blazor. Just like the Timeline component for WPF at "https://docs.telerik.com/devtools/wpf/controls/radtimeline/overview".

I need that component or something similar to show time based instances of activity on a particular item. A lack of such visualisation feature is making us hold on to the WPF one. 

Thanks.

Like the grouping in the Kendo combo box https://demos.telerik.com/kendo-ui/combobox/grouping

<AdminEdit>

This Feature Request would be an umbrella for implementing items grouping for select components (ComboBox, DropDownList, MultiSelect, and others).

</AdminEdit>

It would be nice to switch the color schemes used by the telerik Blazor components on-the-fly in an application (i.e. switch from light mode to dark mode). I realize you have a JS approach to this problem, however that requires maintaining multiple stylesheets and custom javascript, which we are trying to avoid in a Blazor project. I like the approach used by MudBlazor where basically all css colors are variables that can be easily switched at runtime without any javascript:

https://mudblazor.com/wasm/customization/theming/overview

Example live daylight map: https://www.flightradar24.com/

I would like components like the TextBox, NumericTextBox, TextArea, Button to have a method in their reference similar to the FocusAsync() which Microsoft included to the ElementReference in .NET5.

For the time being, you can use JS interop and prepare a suitable selector. Here is a basic example for the button:

@inject IJSRuntime _js

Notes:<br />
- Move this script to a proper place, it is hacked into the component to make this snippet short
- Make sure the ID is unique if you use IDs. THere are other selectors you can use (such as classes, or you can even cascade your selectors to make them more specific)
<br /><br />

<script suppress-error="BL9992">
    function focusElement(selector) {
        var elem = document.querySelector(selector);
        if (elem && elem.focus) {
            setTimeout(function () {
                elem.focus();
            }, 30);
        }
    }
</script>

<TelerikButton OnClick="@FocusBtn">Focus the other button</TelerikButton>

<br /><br />

<TelerikButton Id="@btnId" OnClick="@SpecialBtnAction">I will be focused programmatically</TelerikButton>

@code{
    string btnId = "my-special-btn";

    async Task FocusBtn()
    {
        await _js.InvokeVoidAsync("focusElement", $"#{btnId}");
    }

    async Task SpecialBtnAction()
    {
        Console.WriteLine("special button clicked");
    }
}

There doesn't seem to be a way to deselect the selected row either by clicking on a selected row again or by two-way-binding and setting it to an empty list.

This would be pretty handy as currently the only way that makes sense for me is to make no use of selection mode at all.

A rich text editor style control would be very helpful in specific cases as I could allow the user to edit and style text.

ADMIN EDIT

A Web application (such as Blazor applications) are based on HTML and CSS, and the Telerik UI for Blazor suite already offers a component that outputs HTML: https://demos.telerik.com/blazor-ui/editor/overview. You can even import and export its content from/to an MS Word document (or other formats) through the Telerik Document Processing Libraries that come with your license) as shown here: https://github.com/telerik/blazor-ui/tree/master/editor/ImportExport.

Hi, 

I reported this last week but it got declined ??  Perhaps a picture will help

The default grid displays the filter icon OVER the text and this makes the text unreadable.  This is just the material format from your websites themebuilder

The icon should be closer to the column width adjuster - as you can see from the attachment there is more space between the columns than there is text

I would expect it to be  "| Description  Y |"  and not "|  Desc... Y        |" which is what its doing.  (really the space between the filter icon and the column adjusted is just wasted and there seems to be no way to fix it)

I've tried to move the k-i-filter using CSS and while giving it a left margin of 32px is working ok and making it look reasonable, it still has the circle highlighter when you click it in the wrong place and I can't figure out how to move that also.

Hi,

I have a grid, it has quite a few columns - maybe 10-15, and this is causing 2 problems which are kind of related.

First problem is it tries to squash them all onto the screen making them all narrow and that hides the header text - I have played with horizontal scrollbar but so far I've only managed to resize them after it loads (or to workaround that I have tried save state after I've resized them with some success, but i'd really prefer the default starting point to be wider than the screen - if you have an example you can show me how to do this?)

Next problem is when I add a filter row to it - its basically unusable.  Even though the columns are narrow, they look like they should be wide enough, but instead what happens is the filter button appears in the middle by itself and nothing else appears - sometimes I see " ___ Y      "  but most of the time its "        Y         ".  It seems very poor use of space by default.  This is the material theme. 

Can you help?  I did try with the filter menu but it is more complicated for our users and they prefer the idea of filterrow, plus it also crashes intermittently (see below for callstack).

I see a good solution for angular (PopupSettings.appendTo)

https://www.telerik.com/forums/datepicker-doesn%27t-open-in-ionic-modal#5117655

but blazor only has the PopupClass attribute to work with.  Assigning that a class with a large z-index didn't help

Having the ability to specify sections and then allowing the user to expand the section can be very helpful for complex content or menus.

The sections can be expanded so 1 is visible always or multiple can be expanded.

It would be really cool to be able to edit documents much like the WPF syntax editor.

Our use case is that we use blazor for our admin tools and we need to give a better look and feel (color coding) to some stored SQL and XML.  Nothing fancy just a better experience.

It would be helpful if I had a rating control similar to Rating - MudBlazor.

Further it would be helpful if the selected/unselected items could be different visually for colors and icons.

The attributes that the Telerik Input components, FormItem, and FormGroup should all be consistent in the attributes that are supported.  For example, the TelerikSlider component doesn't support an Id property.  The FormGroup component doesn't support a Class property.

If I place the Slider inside a FormItem Template and provide my own label. I can't associate the label with the Slider since there is no Id property.

Also, if I am using a FormGroup to make sure that two input controls are shown horizontally install of vertically, I can't override the gray horizontal rule that shows with the group, especially when I am not providing LabelText.  I don't want to override this at the TelerikForm as I would like the default behavior in specific instances.

The attached screen shot highlights the issue.  Here is the razor component markup.  Note: Replace the custom RecSetSelector component with a dropdownlist.
