My Nullable DateOnly field shows as 1/1/2001 - I would expect it to be a more sensible default. The problem is applicable only for the Form autogenerated DatePicker. The same issue is applicable for the TimeOnly type.
===ADMIN EDIT===
In the interim, as a viable workaround, you can utilize the FormItem Template and declare a TelerikDatePicker like this:
@using System.ComponentModel.DataAnnotations
<TelerikForm Model="@PersonModel">
<FormValidation>
<DataAnnotationsValidator></DataAnnotationsValidator>
</FormValidation>
<FormItems>
<FormItem>
<Template>
<label for="country">Date of Birth:</label>
<TelerikDatePicker @bind-Value="@PersonModel.DOB" Width="200px" />
</Template>
</FormItem>
</FormItems>
</TelerikForm>
@code {
private Person PersonModel { get; set; } = new Person() { DOB = null };
public class Person
{
[Display(Name = "Date of Birth")]
public DateOnly? DOB { get; set; }
}
}
When I updated to the latest version I noticed that the FormItems in AuthorizedViews were moved to the bottom of the form, Quick example:
<TelerikForm>
<FormItems>
<AuthorizeView>
<Authorized>
<FormItem Field="First"/>
</Authorized>
</AuthorizeView>
<FormItem Field="Second"/>
</FormItems>
</TelerikForm>will end up like
<TelerikForm>
<FormItems>
<FormItem Field="Second"/>
<FormItem Field="First"/>
</FormItems>
</TelerikForm>
Currently, you can split the TelerikForm into multiple columns via the Columns parameter. These columns will have equal widths. I would like to have the ability to define custom width per column.
<AdminEdit>
You can use the following code snippet as a workaround with some considerations:
- The k-grid-cols-2 class is a dynamic one. The "2" segment maps to the number of the columns defined via the Columns parameter exposed for the <TelerikForm>
- If there are more/less than two columns, you should change the values for the grid-template-columns accordingly.
<style>
.non-equal-columns .k-form-layout.k-grid-cols-2 {
grid-template-columns: 71% 28.5%;
}
</style>
@using System.ComponentModel.DataAnnotations
<TelerikForm Model="@person" ColumnSpacing="25px" Columns="2" Class="non-equal-columns">
<FormValidation>
<DataAnnotationsValidator></DataAnnotationsValidator>
</FormValidation>
<FormItems>
<FormGroup LabelText="Personal Information" ColumnSpacing="15px">
<FormItem LabelText="First Name" Field="@nameof(Person.FirstName)"></FormItem>
<FormItem LabelText="Last Name" Field="@nameof(Person.LastName)"></FormItem>
<FormItem LabelText="Age" Field="@nameof(Person.Age)"></FormItem>
<FormItem LabelText="Email" Field="@nameof(Person.Email)"></FormItem>
</FormGroup>
<FormGroup LabelText="Employee Information" Columns="2" ColumnSpacing="15px">
<FormItem LabelText="Company Name" Field="@nameof(Person.CompanyName)"></FormItem>
<FormItem LabelText="Position" Field="@nameof(Person.Position)"></FormItem>
</FormGroup>
</FormItems>
</TelerikForm>
@code {
public Person person { get; set; } = new Person();
public class Person
{
[Required(ErrorMessage = "The First name is required")]
public string FirstName { get; set; }
[Required(ErrorMessage = "The Last name is required")]
public string LastName { get; set; }
[Range(18, 120, ErrorMessage = "The age should be between 18 and 120")]
public int Age { get; set; }
[Required]
[EmailAddress(ErrorMessage = "Enter a valid email")]
public string Email { get; set; }
[Required]
public string CompanyName { get; set; }
[MaxLength(25, ErrorMessage = "The position can be maximum 25 characters long")]
public string Position { get; set; }
}
}</AdminEdit>
Recently a readonly attribute has been added to a number of input fields. This was a great addition. Thank you!
Would it be possible to add this attribute to Telerik Form?
Example:
<FormItem Enabled="false" ReadOnly="true"/>
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.

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)) )" />
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'
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.
Here is a TelerikForm with a FormItem (1) for a boolean field. Another FormItem (2) should render, depending on the boolean field (1). This does not work with a TelerikForm, but works with a standard EditForm.
The workaround for a TelerikForm is to use a FormItem Template with a TelerikCheckBox. This is demonstrated below as well.
<EditForm Model="@_data">
<label>Condition 1 (InputCheckbox):</label>
<InputCheckbox @bind-Value="@_data.Value1" />
<br />
@if (_data.Value1)
{
<label>Result 2</label>
<InputCheckbox DisplayName="Result 2:" @bind-Value="@_data.Value2"></InputCheckbox>
}
</EditForm>
<h1>TelerikForm</h1>
<TelerikForm Model="@_data">
<FormItems>
<FormItem LabelText="Condition 1 (FormItem):" Field="@nameof(_data.Value1)"></FormItem>
<FormItem>
<Template>
<label for="x">Condition 1 (TelerikCheckBox):</label>
<br />
<TelerikCheckBox Id="x" @bind-Value="_data.Value1" />
</Template>
</FormItem>
@if (_data.Value1)
{
<FormItem LabelText="Result 2:" Field="@nameof(_data.Value2)"></FormItem>
}
</FormItems>
</TelerikForm>
@code {
private ExampleDto _data { get; set; } = new ExampleDto();
public class ExampleDto
{
public string TextValue { get; set; }
public bool Value1 { get; set; }
public bool Value2 { get; set; }
}
}
I would like to use manually declared and autogenerated fields together.
I believe this currently exists for the Grid
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; }
}
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>
