When i use the source code instead of install the library from nuget, i find that The plugin is not compatible with the latest release of FluentValidation Plugin,
The maximum version of fluentvalidation allowed is 7.1.1
I cant put place holder with ValidatableEntryControl
Seems to be in both Xaml and code behind.
Hey,
I am trying to extend the functionality to include a validatablePickerControl. I have this largely working except i cannot pass through the ItemDisplayBinding from the xaml. Below is some code snippets. Any pointers greatly appreciated.
public static BindableProperty ItemDisplayBindingProperty = BindableProperty.Create(
nameof(ItemDisplayBinding),
typeof(BindingBase),
typeof(ValidatablePicker));
public BindingBase ItemDisplayBinding
{
get => _picker.ItemDisplayBinding;
set => _picker.ItemDisplayBinding = value;
}
/// <summary>
/// </summary>
public ValidatablePicker()
{
_picker.BindingContext = this;
_picker.SetBinding(Picker.ItemsSourceProperty, nameof(ItemsSource));
_picker.SetBinding(Picker.TitleProperty, nameof(Title));
_picker.SetBinding(Picker.SelectedIndexProperty, nameof(SelectedIndex));
_picker.ItemDisplayBinding = ItemDisplayBinding;
Children.Add(_picker);
_errorLabel.SetBinding(IsVisibleProperty, nameof(IsInValid));
_errorLabel.SetBinding(Label.TextProperty, nameof(Message));
_errorLabel.BindingContext = this;
_errorLabel.TextColor = Color.Red;
Children.Add(_errorLabel);
}
<controls:ValidatablePicker
SelectedIndex="{Binding Model.TypeSelectedIndex, Mode=TwoWay}"
ItemsSource="{Binding AssetTypes}"
ItemDisplayBinding="{Binding Description}"
BindingName="AssetTypeId"
Title="Select asset type"
/>
I've been using your plugin for a while as the best way to do validation in my Xamarin project.
However, with the recent update to FluentValidation 9.0.1 the plugin does not work any more. The FluentValidation.ValidatorAttribute
package is not supported on 9.+ and that gives a challenge in the AbstractValidationViewModel
method:
public ValidationResult GetValidationResult()
{
var attributeFactory = new AttributedValidatorFactory();
var type = GetType();
var validator = attributeFactory.GetValidator(type);
var results = validator.Validate(this);
return results;
}
as the AttributedValidatorFactory
doesn’t exist any more. I'm not sure how to work around this?
The migration documentation in FluentValidation suggests using an IoC container instead - but that seems quite another approach to what this plugin does - so I'm not sure how to do this (still a little new on DI though I'm building on Prism using DryIoc).
Hoping to get some suggestions to go with.
Thanks in advance!
There are projects which were done in Xamarin and the current nuget package supported well. As Microsoft recommends to migrate to Maui the current nuget package doesn't support it.
Any suggestion and thoughts about it?
