uwp Binding vs x:Bind Binding modes and defaults
Example
There are three modes of XAML bindings exists for either Binding and x:Bind:
- OneTime: Update happens only once, on initialization of the view during
InitializeComponent()call. (ViewModel[sends data when initializing] -> View) - OneWay: View is updated when ViewModel changes. But not in the reverse direction. (ViewModel -> View)
- TwoWay: View is updated when ViewModel changes and vice versa. (ViewModel <-> View)
Default mode of Binding is OneWay and that of x:Bind is OneTime.
Select the modes like this:
<TextBlock Text="{Binding SomeText, Mode=TwoWay}" /> <!-- Binding -->
<TextBlock Text="{x:Bind SomeText, Mode=OneWay}" /> <!-- x:Bind -->
