A small validation library for WPF that uses a fluent interface and allow display messages near controls in GUI with MVVM Inspired FluentValidation by Jeremy Skinner
NuGet Package
Install-Package ReactiveValidation
Sample
public class CarViewModel : ValidatableObject
{
public CarViewModel()
{
Validator = GetValidator();
}
private IObjectValidator GetValidator()
{
var builder = new ValidationBuilder<CarViewModel>();
builder.RuleFor(vm => vm.Make).NotEmpty();
builder.RuleFor(vm => vm.Model).NotEmpty().WithMessage("Please specify a car model");
builder.RuleFor(vm => vm.Mileage).GreaterThan(0).When(model => model.HasMileage);
builder.RuleFor(vm => vm.Vin).Must(BeAValidVin).WithMessage("Please specify a valid VIN");
builder.RuleFor(vm => vm.Description).Length(10, 100);
return builder.Build(this);
}
private bool BeAValidVin(string vin)
{
// custom vin validating logic goes here
}
//Properties with realization INotifyPropertyChanged goes here
}
In xaml to control which displayed errors set attached property ReactiveValidation.AutoRefreshErrorTemplate
equal True
and binding your property
xmlns:b="clr-namespace:ReactiveValidation.WPF.Behaviors;assembly=ReactiveValidation"
...
<TextBox b:ReactiveValidation.AutoRefreshErrorTemplate="True"
Text="{Binding Make, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
Done!
You also can use template which display errors messages near control
To do this, set to attached property ReactiveValidation.ErrorTemplate
value from static class ErrorTemplates.ExtendedErrorTemplate
. If you are use default styles this will be look like this:
xmlns:b="clr-namespace:ReactiveValidation.WPF.Behaviors;assembly=ReactiveValidation"
xmlns:t="clr-namespace:ReactiveValidation.WPF.Templates;assembly=ReactiveValidation"
...
<ResourceDictionary>
<Style x:Key="TextBox" TargetType="TextBox">
<Setter Property="b:ReactiveValidation.AutoRefreshErrorTemplate" Value="True" />
<Setter Property="b:ReactiveValidation.ErrorTemplate" Value="{x:Static t:ErrorTemplates.ExtendedErrorTemplate}" />
</Style>
</ResourceDictionary>
Apply style and nothing more!
<TextBlock Grid.Row="0" Grid.Column="0" Text="Make: " />
<TextBox Grid.Row="0" Grid.Column="1" Style="{StaticResource TextBox}"
Text="{Binding Make, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBlock Grid.Row="1" Grid.Column="0" Text="Model: " />
<TextBox Grid.Row="1" Grid.Column="1" Style="{StaticResource TextBox}"
Text="{Binding Model, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBlock Grid.Row="2" Grid.Column="0" Text="Has mileage: " />
<CheckBox Grid.Row="2" Grid.Column="1"
IsChecked="{Binding HasMileage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBlock Grid.Row="3" Grid.Column="0" Text="Mileage: " />
<TextBox Grid.Row="3" Grid.Column="1" Style="{StaticResource TextBox}" IsEnabled="{Binding HasMileage}"
Text="{Binding Mileage, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBlock Grid.Row="4" Grid.Column="0" Text="Vin: " />
<TextBox Grid.Row="4" Grid.Column="1" Style="{StaticResource TextBox}"
Text="{Binding Vin, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
<TextBlock Grid.Row="5" Grid.Column="0" Text="Description: " />
<TextBox Grid.Row="5" Grid.Column="1" Style="{StaticResource TextBox}"
Text="{Binding Description, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}" />
