This repository contains useful controls/converter/classes to work with WPF. The current version of the library is also available on NuGet.
This repository contains a customizable PropertyGrid for WPF.
- Many data types are supported by default: String, Boolean, Date, DateTime, Number, Enum, Multi-Valued Enum, Byte[], Guid, etc.,
- Property names are decamelized by default (FirstName => First Name) unless you use the
DisplayNameAttribute, - Common attributes are supported:
DisplayNameAttribute,CategoryAttribute,BrowsableAttribute,ReadOnlyAttribute, - Customizable:
CustomEditor=DataTemplateYou can create your own editors to provide a better UX to your user (Slider, Url, Password, etc.) by creating aDataTemplate
<Grid>
<Grid.Resources>
<samples:Customer x:Key="Customer"/>
</Grid.Resources>
<windows:PropertyGrid xmlns:windows="clr-namespace:SoftFluent.Windows;assembly=SoftFluent.Windows"
SelectedObject="{StaticResource Customer}" />
</Grid>Go to the documentation
The AutoObject class is a light class which implements INotifyPropertyChanged and IDataErrorInfo so you can easily and quickly create MVVM like classes with data-binding and validation
Stop writing boring converters, use the UniversalConverter!
When you create an application using WPF, you often have to write converters to change one value to the desired type. The .NET Framework already provides some basics converter such as BooleanToVisibilityConverter. These converters are very specifics and usually not very configurable. For example you cannot change the visibility from Collapsed to Hidden.
Let’s see how to use it for a very basic (and to be honest, quite useless) conversion:
<Window.Resources>
<windows:UniversalConverter x:Key="TypeConversionUniversalConverter" />
</Window.Resources>
<CheckBox IsChecked="{Binding Converter={StaticResource TypeConversionUniversalConverter},
Mode=OneWay}" DataContext="true"/>
<CheckBox IsChecked="{Binding Converter={StaticResource TypeConversionUniversalConverter},
Mode=OneWay}" DataContext="yes"/>In this example, UniversalConverter converts the value to the desired type so string values “true” and “yes” will be converted automatically to the Boolean value “true”.
With UniversalConverter, you can create a list of cases, like a C# switch. For instance, this is how we would reproduce the boolean to visibility converter behavior using the UniversalConverter:
<windows:UniversalConverter x:Key="BooleanToVisibilityConverter">
<cfr:UniversalConverter.Switch>
<cfr:UniversalConverterCase Operator="Equal" Value="True" ConvertedValue="Visible" />
<cfr:UniversalConverterCase Operator="Equal" Value="False" ConvertedValue="Collapsed" />
</cfr:UniversalConverter.Switch>
</cfr:UniversalConverter>Like C#, you can use a default value:
<cfr:UniversalConverter x:Key="BooleanToVisibilityConverter" DefaultValue="Visible">
<cfr:UniversalConverter.Switch>
<cfr:UniversalConverterCase Operator="Equal" Value="False" ConvertedValue="Collapsed" />
</cfr:UniversalConverter.Switch>
</cfr:UniversalConverter>There are currently these operators available:
- Equal,
- NotEqual,
- GreaterThan,
- GreaterThanOrEqual,
- LesserThan,
- LesserThanOrEqual,
- Between: minimum and maximum value included => [min:max[,
- StartsWith,
- EndsWith,
- Contains,
- IsType: type match exactly,
- IsOfType: type or direved types,
- JavaScript: Yes, you can use JavaScript to evaluate a condition!
With some options:
- StringComparison
- Trim
- Nullify
Here’s a list of examples using different operators.
<cfr:UniversalConverter x:Key="HasMultipleLinesConverter" DefaultValue="False">
