.NET MAUI Converters

  • Article

.NET Multi-platform App UI (.NET MAUI) data bindings usually transfer data from a source property to a target property, and in some cases from the target property to the source property. This transfer is straightforward when the source and target properties are of the same type, or when one type can be converted to the other type through an implicit conversion. When that is not the case, a type conversion must take place.

For further information on Converters please refer to the .NET MAUI documentation.

.NET MAUI Community Toolkit Converters

The .NET MAUI Community Toolkit provides a collection of pre-built, reusable converters to make developers lives easier. Here are the converters provided by the toolkit:

ColorToRgbStringConverter The ColorToRgbStringConverter is a converter that allows users to convert a Color value binding to its RGB string equivalent.
ColorToRgbaStringConverter The ColorToRgbaStringConverter is a one-way converter that allows users to convert a Color value binding to its RGBA string equivalent.
CompareConverter The CompareConverter is a one-way converter that take an incoming value implementing IComparable, compares to a specified value, and returns the comparison result.
DateTimeOffsetConverter The DateTimeOffsetConverter is a converter that allows users to convert a DateTimeOffset to a DateTime
DoubleToIntConverter The DoubleToIntConverter is a converter that allows users to convert an incoming double value to an int and vice-versa. Optionally the user can provide a multiplier to the conversion through the Ratio property.
EnumToBoolConverter The EnumToBoolConverter is a one-way converter that allows you to convert an Enum to a corresponding bool based on whether it is equal to a set of supplied enum values. It is useful when binding a collection of values representing an enumeration type to a boolean control property like the IsVisible property.
EnumToIntConverter The EnumToIntConverter is a converter that allows you to convert a standard Enum (extending int) to its underlying primitive int type. It is useful when binding a collection of values representing an enumeration type with default numbering to a control such as a Picker.
ImageResourceConverter The ImageResourceConverter is a converter that converts embedded image resource ID to its ImageSource.
IndexToArrayItemConverter The IndexToArrayItemConverter is a converter that allows users to convert an int value binding to an item in an array. The int value being data bound represents the indexer used to access the array. The array is passed in through the ConverterParameter.

InvertedBoolConverter The InvertedBoolConverter is a converter that allows users to convert a bool to its inverse - true becomes false and vice-versa.
IsEqualConverter The IsEqualConverter is a one-way converter that returns a bool indicating whether the binding value is equal to another specified value.
IsInRangeConverter The IsInRangeConverter is a one-way converter that takes an incoming value implementing IComparable, and a minimum and maximum value, and returns the result of the value being between the minimum and maximum values.
IsListNotNullOrEmptyConverter The IsListNotNullOrEmptyConverter is a one-way converter that converts IEnumerable to a bool value.
