Currently, the Form component does not provide indexer support, or binding to an item of collection. For reference of the feature, you could observe the following documentation of the WPF suite:

https://docs.telerik.com/devtools/wpf/controls/radpropertygrid/features/indexer-support

Currently, the input components in Telerik UI for Blazor use JavaScript to set the value, instead of the value parameter. This is done so that features like Placeholder, Format, and others are available. 

This comes at the cost of delayed rendering of the preset value of the input components. 

Currently, when the AutoGenerated form items are used, the data attributes such as Password and Email are ignored. Model sample:

    public class LoginModel
    {
        [Required, EmailAddress, Display(Name = "Email Address")]
        public string EmailAddress { get; set; }

        [Required, Phone, Display(Name = "Phone Number")]
        public string PhoneNumber { get; set; }
    }

I have a rather large TelerikForm that contains multiple TelerikTabStrip controls that contain FormItems. In the new version 4.1.0  the form items in the tabstrip do not display correctly and the form items not in the tabs are moved to the bottom of the page. The markup in a test project i created shows the tabstrip above and outside the form tag. Works correctly in 4.0.1. I've attached the test razor file.

There is no AriaDescribedBy parameter on the Upload when it's inside a Form. I'd like to be able to associate some elements to further describe some validation messages/hints, but there is no parameter exposing that.

For reference, the Angular FormField component associates the underlying control and its visible messages by assigning the aria-describedby attribute to the focusable element.

Hi, 

I came across some unusual behaviour

I wanted to hide the default form submit button so I could put it elsewhere on the page but once I had an empty FormButton element on the page I was unable to print any more

<FormButtons></FormButtons>

a solution to my problem was to put an empty span in the element

<FormButtons><span></span></FormButtons>

Virtually all web apps nowadays have support for masked inputs. Not quite sure why Telerik Blazor does not, but requesting it, since I can't really go live without it.

Ideally it should also work using data annotations on the model class using [DataType(DataType.Password)]. This way I don't have to specify the form fields and can just rely on the auto-generated form (like I am doing now). I have a lot of forms that have passwords, so it would be annoying to have to specify the fields for all of them.

I have a simple TelerikForm using required validation but for some reason when I set the model via an async call to the server the validation doesn't fire. I am using the same form when I add a new item and the validation is working fine.

When I assign an Id to a FormGroup in TelerikForm, it's value can be seen in code, but neither the attribute nor it's value get rendered.

I would like to use manually declared and autogenerated fields together.

I believe this currently exists for the Grid

Hi, 

It would be nice to have an OnUpdateDebounce for TelerikForm's OnUpdate.

I am currently using a form to filter information with an API call that is shown in a grid.

It would be nice to reduce the number of calls and with larger data we sometime get an earlier query returned after a later one resulting in showing the results for a search of 'T' instead of 'Tom'

Render defined Form items inside a FormItemsTemplate  Example

Line 22 has @nameof(Person.Id) which generates an error, should be without the @ as shown below.

 <TelerikFormItemRenderer Item="@( formItems.First(x => x.Field == nameof(Person.Id)) )" />

I often have the scenario where I need to switch from the autogenerated formitem to a templated version. Mostly because I need a different editor

For example:

<FormItem Field="@nameof(KeyValuesViewModel.Workplace)" LabelText="Workplace" EditorType="@FormEditorType.TextBox"/>

I create something like this:

            <FormItem>
                <Template>
                    <label for="WorkplaceInput">Workplace</label>
                    <TelerikMaskedTextBox Id="WorkplaceInput" Mask="aa aaaaaa" Enabled=@WorkplaceEnabled OnChange="OnWorkplaceChanged" @ref=@WorkplaceTextBoxRef />
                    <TelerikValidationMessage For="@(() => KeyValuesViewModel.Workplace)" />
                </Template>
            </FormItem>

It would speed up things if I just could use the "light bulb" and convert it. Instead coding it manually, copy, paste, edit the copied version. Over and over again.
