Bug report
Using a UI for ASP.NET MVC/Core Form, if a boolean property is defined as required with the [Required] attribute, and the Hint() option is not defined, the Form does not validate the checkbox.
Reproduction of the problem
Please visit the following Live demo, and submit the form.
Current behavior
The form will submit without validating the checkbox.
Expected/desired behavior
The Required attribute should be evaluated for validation.
Environment
- Kendo UI version: 2023.2.606
- jQuery version: All Supported Versions
- Browser: all
Bug report
Form TagHelper does not expose a ValidationSummary tag.
Current behavior
The Form TagHelper's exposes only a validation-summary attribute instead of a validation-summary tag which prevents adding options such as: Container, Enable, Template, and more.
In comparison to the HTML Helper .ValidationSummary() API configuration which allows the following:
.Validatable(v =>
{
v.ValidationSummary(validationSummary => {
validationSummary.Enable(true);
validationSummary.TemplateId("someTemplate");
validationSummary.Container("myContainer");
});
})
Expected/desired behavior
It would be a good idea to consider altering the current validation-summary attribute into a standalone tag helper. However, this will inevitably lead to a breaking change.

.ServerFiltering(true);
});
});
})

public class FormViewModel
{
public List<ProductViewModel> MultiSelect { get; set; }
}

Bug report
The Form TagHelper does not provide support for hidden fields, similar to the HtmlHelper.
Reproduction of the problem
The Form TagHelper does not allow similar built-in configuration:
.Items(i =>
{
i.Add()
.Field(f => f.UserID)
.Editor(editor => editor.Hidden());
})
Expected/desired behavior
The Form TagHelper should support hidden inputs.
Workaround
Similar result can be achieved by setting the editor-handler attribute, creating a hidden input and setting an empty label:
<form-items>
<form-item field="UserID" editor-handler="hiddenEditor" >
<item-label text=" " />
</form-item>
</form-items>
<script>
function hiddenEditor(container, options) {
$('<input type="hidden" data-bind="value: ' + options.field + '" name="' + options.field + '"/>')
.appendTo(container);
}
</script>

### Bug report
When the DropDownTree control is added as a Form editor through the Editor() method, there is an ArgumentNullException "Value cannot be null. (Parameter 'key')".
### Reproduction of the problem
Attached is a demo that replicates the issue.
If the DropDownTree is defined outside of the Form, it is bound to the Model property as expected.
### Expected/desired behavior
The DropDownTree editor should bind to the Model property in the Form.
### Environment
* **Kendo UI version: 2022.1.412
* **jQuery version: 1.12.4
* **Browser:** [all]
.Items(items =>
{
items.Add()
.Field(f => f.Type)
.Label(l => l.Text("Type:"))
.Editor(e =>
{
e.Upload()
}
}
At moment the Form Group does not support the HtmlAttributes() method. Is it possible to implement?
For example:
@(Html.Kendo().Form<Model>()
.Name("exampleForm")
...
.Items(items =>
{
items.AddGroup()
.HtmlAttributes(...)
.Items(i => {...});
})
)
Add support for hidden fields. There could be an alternative way of adding them to the Items collection, e.g.
.AddHidden()
Consider the cases when the hidden field is bound to a model field and when it isn't bound to the model. The latter could be a scenario involving antiForgeryTokens:
<input type="hidden" name="__RequestVerificationToken" value="token" />In both cases you should be able to set the value of the hidden field programmatically and submit it with the form.
The Kendo Form should include native ListBox editor support including joining and swapping items between two ListBox's using ConnectWith.
To use a ListBox in the Kendo Form currently requires a custom editor which is overly complex.
Bug report
RadioGroup Validation fails always when Component is bound to Model
Reproduction of the problem
- Define a FormViewModel and set its data annotation to [Required]
- Initialize a Form and pass it the FormViewModel
- In the Form:
- set up Validation
- define an Item that uses the RadioGroup Editor
- Run the application choose a RadioGroup option and submit the Form
Current behavior
All the inputs of the RadioGroup Component get the data-val-required property and validation always fails
Expected/desired behavior
The RadioGroup's Validation should succeed, if one of the options is selected
Environment
- Kendo UI version: 2021.1.330
- Browser: [all ]
Provide built-in integration of RadioButton / RadioGroup in the Form
i.e. : .Editor(e =>{
e.RadioButton();
});
});
Form with MultiSelect editor does not submit selected values in the MultiSelect.
Provide an option to configure orientation per groups.
