Enum filter controls

16/09/2022 admin Aucun commentaire

For having a CheckBox selection for enum type like this

and make easy filter on collection

you can use this two components

EnumFilterControl
EnumFilterComboControl

EnumFilterControl

Is base control for showing enum in grid

 public class EnumFilterControl : Control, INotifyPropertyChanged

            this.OnPropertyChanged(property.Member.Name);
        }
        //public void OnPropertyChanged(string name)
        //{
        //    this.OnPropertyChanged(this, new PropertyChangedEventArgs(name));
        //}
        public void OnPropertyChanged([CallerMemberName] string propertyName = null)

Common properties

Properties	Descriptions	Default
Title	Title for control (show at left)	Filter
ShowHiddenEnum	Define if you must show item of enum with ExcludeFilterAttribute	false

if you have an enum with (usage of attribues)

[Flags] 
[TypeConverter(typeof(LogLevelTypeConverter))] 
public enum LogLevel : int 
{ 
   [ExcludeFilter] 
   None = 0x00, 

   Info = 0x01, 
   Alert = 0x02, 
   Error = 0x04, 
   Debug = 0x08, 
   Critical = 0x10, 

   [ExcludeFilter] 
    All = Info | Alert | Error | Debug | Critical, 
}

[Flags]

[TypeConverter(typeof(LogLevelTypeConverter))]

public enum LogLevel : int

{

[ExcludeFilter]

None = 0x00,

Info = 0x01,

Alert = 0x02,

Error = 0x04,

Debug = 0x08,

Critical = 0x10,

[ExcludeFilter]

All = Info | Alert | Error | Debug | Critical,

}

in this case when ShowHiddenEnum=true, you can show None and All

And if you use HideFilterColorAttribute on enum like this

[Flags]
[HideFilterColor]
public enum LogLevel : int
{
....
}

[Flags]

[HideFilterColor]

public enum LogLevel : int

{

....

}

Force to hide color even ShowColor=true

for TypeConverter the converting is automatic

Properties	Descriptions	Default
ShowColor	define if rectangle color is visible and ItemsConverter is define for color (not return null) or TypeConverter exist and can convert to Brush	true
ShowAll	Show All CheckBox	true
ShowNone	Show None CheckBox	true
AllText	Text for All CheckBox	true
NoneText	Text for None CheckBox	true
Selector	Is the selectedItems for this component with null if all selected object[] empty if none selected object[] contains enum element checked	null
AllowAll	do not use, is used for disable all checkbox
AllowNone	do not use, is used for disable none checkbox
All	do not use, is used for check all checkbox
None	do not use, is used for checknone checkbox
CheckWith	for specify size of CheckBox if you want	80D
Type	Is the type of enum you want to show	null

ValidationRules with binding

01/09/2022 admin Aucun commentaire

It’s not possible to have a binding in ValidationRule because this validation rule class is not in visual hierachical tree, and sometime is necessary to chech for example is the text is not in list of the DataContext or or two DateTime, start and end are consistent together.

See my sample for Text and List in DataContext

Window for test

 public partial class MainWindow : Window
    {
        public MainWindow()
        {
            InitializeComponent();
            this.DataContext = this;
        }

        public string TX { get; set; }
        public List<string> List { get; }
            = new List<string> {
                "alpha",
                "beta",
                "gamma",
                "66"
            };
    }

public partial class MainWindow : Window

{

public MainWindow()

{

InitializeComponent();

this.DataContext = this;

}

public string TX { get; set; }

public List<string> List { get; }

= new List<string> {

"alpha",

"beta",

"gamma",

"66"

};

}

and xaml

<TextBox x:Name="xx"
                 HorizontalAlignment="Left"
                 Height="30"
                 Margin="30,30,0,0"
                 TextWrapping="Wrap"
                 VerticalAlignment="Top"
                 Width="250">
            <TextBox.Resources>
                <local:DataContextObject x:Key="dco"
                                         DataContext="{Binding }" />
            </TextBox.Resources>
            <TextBox.Text>
                <Binding Path="TX"
                         UpdateSourceTrigger="PropertyChanged">
                    <Binding.ValidationRules>
                        <local:SampleRule DataContext="{StaticResource dco}" />
                    </Binding.ValidationRules>
                </Binding>
            </TextBox.Text>
        </TextBox>

<TextBox x:Name="xx"

HorizontalAlignment="Left"

Height="30"

Margin="30,30,0,0"

TextWrapping="Wrap"

VerticalAlignment="Top"

Width="250">

<TextBox.Resources>

<local:DataContextObject x:Key="dco"

DataContext="{Binding }" />

</TextBox.Resources>

<TextBox.Text>

<Binding Path="TX"

UpdateSourceTrigger="PropertyChanged">

<Binding.ValidationRules>

<local:SampleRule DataContext="{StaticResource dco}" />

</Binding.ValidationRules>

</Binding>

</TextBox.Text>

</TextBox>

and two class for using

DataContextObject for storing DataContext of TextBox

public class DataContextObject : Freezable
    {
        protected override Freezable CreateInstanceCore() =>
            new DataContextObject();

        public object DataContext
        {
            get { return GetValue(DataContextProperty); }
            set { SetValue(DataContextProperty, value); }
        }
        public static readonly DependencyProperty DataContextProperty = 
            DependencyProperty.Register(nameof(DataContext), 
                typeof(object), 
                typeof(DataContextObject), 
                new UIPropertyMetadata(null));
    }

public class DataContextObject : Freezable

{

protected override Freezable CreateInstanceCore() =>

new DataContextObject();

public object DataContext

{

get { return GetValue(DataContextProperty); }

set { SetValue(DataContextProperty, value); }

}

public static readonly DependencyProperty DataContextProperty =

DependencyProperty.Register(nameof(DataContext),

typeof(object),

typeof(DataContextObject),

new UIPropertyMetadata(null));

}

and ValitationRule

 public class SampleRule : ValidationRule
    {
        public object DataContext { get; set; }

        public override ValidationResult Validate(object value, CultureInfo cultureInfo)
        {
            if(DataContext is DataContextObject dco && dco.DataContext is MainWindow mw)
            {                
                if(mw.List.Find(x => x.Equals((string)value))== null)
                    return ValidationResult.ValidResult;
                else
                    return new ValidationResult(false, $"{value} exist in list ");
            }
            return new ValidationResult(false, $"problem with binding");
        }
    }

public class SampleRule : ValidationRule

{

public object DataContext { get; set; }

public override ValidationResult Validate(object value, CultureInfo cultureInfo)

{

if(DataContext is DataContextObject dco && dco.DataContext is MainWindow mw)

{

if(mw.List.Find(x => x.Equals((string)value))== null)

return ValidationResult.ValidResult;

else

return new ValidationResult(false, $"{value} exist in list ");

}

return new ValidationResult(false, $"problem with binding");

}

here somes template for validation error
