LetType<T> Class - Fuse Documentation

This entity is experimental and might be changed or removed in a future release.

Provides a bindable value for use in UX. This assists in combining animations and transitions in the UX without needing to use JavaScript intermediates. It is not meant to store application state, being intended only for UI level changes and effects.

Unlike Let this enforces a specific value type and is suitable for use with Change, Set, and other property bindings.

These values are two-way bindable (like Observables), for example:

<LetString Value="hello" ux:Name="a"/>
<TextInput Value="{a}"/>
<Text Value="{a}"/>

Typing in the TextInput will modify the value of a and update the Text value.

Show Uno properties and methods

Interface of LetType<T>

LetType Constructor uno

Creates a new LetType<T>

SetValue(T, IPropertyListener) uno

Value : T ux

Inherited from LetBase

OnRootedValue uno

SetObjectValue(object, IPropertyListener) uno

Inherited from Node

Add(Binding) uno

Bindings : IList of Binding ux

The list of bindings belonging to this node.

ContextParent : Node uno

The context parent is the semantic parent of this node. It is where non-UI structure should be resolved, like looking for the DataContext, a Navigation, or other semantic item.

FindByType<T> : T uno

FindNodeByName(Selector, Predicate<Node> (Node)) : Node uno

Finds the first node with a given name that satisfies the given acceptor. The serach algorithm works as follows: Nodes in the subtree are matched first, then it matches the nodes in the subtrees ofthe ancestor nodes by turn all the way to the root. If no matching node is found, the function returns null.

GetNearestAncestorOfType<T> : T uno

Insert(int, Binding) uno

IsRootingCompleted : bool uno

Whether rooting for this node is completed. Returns false if unrooting has started.

IsRootingStarted : bool uno

Whether rooting of this node has started. Note that even if this property returns true, rooting may not yet be completed for the node. See also IsRootingCompleted.

Name : Selector ux

Run-time name of the node. This property is automatically set using the ux:Name attribute.

NextSibling<T> : T uno

Returns the next sibling node of the given type.

OnDataChanged(string, object) uno

OnRooted uno

If you override OnRooted you must call base.OnRooted() first in your derived class. No other processing should happen first, otherwise you might end up in an undefined state.
