Converters In Xamarin
This page lists all currently available converters for customizing Xamarin XAML. This Page is WIP!!!
| Converter | 2-Way | Description |
|---|---|---|
| BooleanConverter | ✓ | Interprets the boolean value and returns it. If the value cannot be interpreted, false is returned. |
| BooleanInvertConverter | ✓ | Interprets and converts a boolean into its inverted value. If the value cannot be interpreted, false is returned. |
| BooleanToFontAttributeConverter | ✗ | Converts a boolean into a [font attribute] value. In detail, if the value is true, the parameter is interpreted (Bold, Italic, None) and returned. The default returned font-attribute is None. |
| ByteToImageSourceValueConverter | ✗ | Converts a byte stream value into an image source. |
| ChildAreaTemplateConverter | ✗ | Returns a ChildAreaTemplate from a ContentViewModel or null if the ViewModel cannot be interpreted. |
| ChildItemSelectionModeToSfListViewSelectionModeConverter | ✓ | Converts a ChildItemSelectionMode to [Syncfusion's ListViewSelectionMode]. Default is "Single". |
| ClassificationToBoolConverter | ✗ | Returns a boolean indicating whether the given ContentViewModel is successfully classified. |
| ContainsToBoolConverter | ✗ | Checks if the delivered value is contained within a collection of values (delivered in the parameter, seperated with |). If the value is contained, true will be returned, else false. The functionality is similar to the ContainsToVisibilityConverter in the WinX project. |
| ContainsToInvertedBoolConverter | ✗ | Same as the ContainsToBoolConverter, but with inverted output. The functionality is similar to the ContainsToVisibilityConverter in the WinX project. |
| ContentAreaTeamplateConverter | ✗ | This converter is not yet finished and just returns the UBIKContentArea if the value is a ContentViewModel. |
| DateTimeOffsetToDateConverter | ✓ | Converts a DateTimeOffset to the correct DateTime. If the value cannot be interpreted, a new DateTime, generated from the device's current time (DateTime.Now) is returned. |
| DateTimeToFromNowStringConverter | ✗ | Returns a DateTime into a human-readable and easily understandable string message (the last applying one will be taken):
|
| DebugConverter | ✓ | A converter returning the given value for debug reasons. |
| DistanceToStringConverter | ✗ | Returns the given value interpreted as length. Values are returned in kilometers with two comma digits (e.g. 2.84km), values smaller than 1km are returned as meters and NaN will be returned as infinity. If the value cannot be interpreted, an empty string will be returned. |
| EqualityToBoolConverter | ✗ | Returns true if the given value and parameter are equal to each other, false otherwise. |
| EqualityToInvertedBoolConverter | ✗ | Returns true if the given value and parameter are not equal to each other, false otherwise. |
| SelectionChangedEventArgsConverter | ✗ | Converts an Syncfusion ItemSelectionChangedEventArgs to a ListSelectionChangedEventArgs. The use-case of this converter is highly specific. |
| FilterCriterionToValueConverter | ✓ | Converts a FilterCriterion to its value. The functionality is similar to UWP's FilterCriterionToValueConverter. |
| GuidPropertyValueConverter | ✓ | Returns the first item of the parameter's Source-ViewModel that matches the given GUID value. If none is found, null is returned. |
| IntToColorConverter | ✗ | Converts an integer value to a color. If the value cannot be interpreted, the converter tries to parse the parameter as a color to return it. If everything fails, transparent is returned. |
| ItemCountToBoolConverter | ✗ | This converter has a property to set the boolean return value, called LesserThanReturnValue. This property-value will be returned if the given value is smaller than or equal to the threshold (parameter, defaults to 0). If the value is bigger than the threshold, the inverted LesserThanReturnValue will be returned. In any other case (like the value cannot be interpreted), false is returned, so it's a good idea to set the converter's property in a way that the return is only true if you need it. |
| ItemCountToOverflowConverter | ✗ | Creates a human-readable text indicating how many items are available. The value will be interpreted as the total item count and the parameter as overflow threshold (defaults to 99). If there are more items than the overflow, the overflow value with a + sign will be returned (e.g. 99+). If not, the value itself will be returned. If everything fails, null is returned. |
| NullToBoolConverter | ✓ | Null or an empty string value get converted to true, and everything else to false. |
| NullToInvertedBoolConverter | ✓ | Null or an empty string value get converted to false, and everything else to true. |
| PathToImageSourceValueConverter | ✓ | Reads the path provided as parameter and creates an image source from it. |
