This is a request for a new feature that I haven't seen across all of the Telerik products.

A new control that makes use of the HTML Canvas to allow for inking within web applications.

Can be used for free hand writing (inking) on mobile devices instead of requiring online keyboard in limited real estate scenarios. Can use to implement signature blocks on forms, convert to text, etc.

 

Many applications need an ability to schedule people/resource.

Provide ability to define icons for input prefix and suffix. Thus, provide mechanism for built-in validation icon as well.

Example image with suffix icons to give you better perspective of the feature.

I would like to see the Captcha component to the Telerik UI for Blazor suite.

This is just feedback on two of your old controls that were really useful that I would like to use again on Microsoft's new technology.

I saw the FloatingActionButton Web control available in KendoUI and ASP.NET Core and I would like it in UI for Blazor: https://demos.telerik.com/kendo-ui/floatingactionbutton/index

We use QueryableExtensions.ToDataSourceResultmethod to load some data in our component. And at some moment we need to cancel data loading. But ToDataSourceResult method doesn’t support CancellationToken. So we are forced to use a workaround and just ignore the task's result. But task is still executing and causing the performance hit…

It would be great if you implemented support for this feature!

Please add a side navigation bar for Blazor.

hello, 
i wanted to know if it's possible to make fully rtl theme in ui for blazor or not i have been trying to make an rtl theme but i got some problems.
and also is it possible to use other types of calendar in datepicker  (like arabic calendar)? 

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>

I would like to have the TabIndex property to all input components, like ComboBox, NumericTextBox, all date inputs and pickers and so on.

Currently working on moving from winform to Blazor and found a feature not supported in Telerik atm.

Getting current error when trying to enable Virtualiztion inside a grid

Groupable is not supported with the Virtualization feature of Telerik Grid

Where im already setting grouping on one of the columns

This is kind of hard to explain, so please see the attached Before and After videos.  In these videos, I'm using a brand new .NET 6 console app.

In the Before video, the Telerik UI for Blazor extension is disabled.  After I type `Console` and hit the period, I see intellisense like I expect to.

In the After video, the extension is enabled.  I'm typing the same thing and hitting period, but something interrupts the period keystroke, and it never appears.  Instead, it just closes the intellisense window.

I used a new console app as an example, but it's happening in all projects.  It's also happening with other keys like semicolons, spaces, and tabs.  It's causing a huge amount of typos and making so I often have to hit keystrokes twice in order for them to register.

I tried doing a full reinstall of Visual Studio.  Everything's fine until I install the Telerik extension, then it starts.  If I disable the extension, the issue goes away.

I am very surprised that Multiselect is missing among the list of Blazor controls being offer.  Syncfusion already offers a full-feature Multiselect.  Is a Multiselect on the road map?  When should we expect it.  Currently the only way to have a select list with multiple selections enabled is a pretty ugly JSInterop hack.  I am honestly considering switching to Syncfusion as they seemed to be far ahead of Telerik in Blazor development.

Hi,

I would like to have a Expand/Collapse All Grid Groups button in the Grid Header. I know this is possible to do so programmatically outside of the grid but my users want it inside the Grid. 

Thanks,

See more details in the following KB article: https://docs.telerik.com/blazor-ui/knowledge-base/textbox-validate-on-change and if the behavior and solution there do not fit your needs, leave your comments and ideas on how you want this exposed for configuration and what the desired behavior is. Also, make sure to Vote for this enhancement so we can gauge the public interest in it.

Hi,

In most of my projects I use the ObjectGraphDataAnnotationsValidator component for validating complex types; and I also use a lot of your components. I've noticed what I *think* might be a clash between this validator and some of your input components. I've built a simple (and crude) example but I think it demonstrates the problem.


In the example code we have a table with 2 cells - in both cells we have an EditForm and 10 TelerikTextArea components. The first cell's EditForm contains a ObjectGraphDataAnnotationsValidator instance and the 2nd cell doesn't. Hopefully when you try to reproduce you will notice a distinct difference in performance with the performance of the 2nd EditForm being great, while the 1st EditForm is quite laggy and gets worse the more items you add.


I'm wondering if there is a clash here between the ObjectGraphDataAnnotationsValidator and the input components or I'm using them incorrectly?


Thanks
Michael.

    protected override void OnInitialized()
    {
        Items = new List<DataItem>();
        for (var i = 1; i <= 10; i++)
        {
            Items.Add(new DataItem { TextValue = $"This is item number {i}." });

    public class DataItem
    {
        public string TextValue { get; set; }

It would be very useful to have a control like a dropdown datagrid. Like the one radzen has. With multiple columns paging etc.

Also in addition to this a treegrid dropdown would be one thing that would sky rocketed the component suite.

It would be very nice to be able to have a heatmap style chart where each cell is dependant on the matching x/y values.
In addition each cell is colored or styled based on the x,y combination.

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?
