binding

While this is just pseudo code, the specific error we receive in angular is : "Uncaught Error: Syntax

I am using the technique for view switching (with multiple view controllers) as explained in the Hillegass book.

问题 Say I have two classes that can reference a third UI object (in this example a button). In addition, the parent class can contain an element of the child class.

问题 In short(?), I have a ListView (target) one-way bound to an XmlDataProvider (source) two-way bound to a TextBox (target) using standard XAML for the control bindings and custom XAML extensions for the bindings to the XmlDataProvider . This is a convenience for the application as the XmlDataProvider is dynamically loaded from user inputs after the application is running,... Anyway, at run-time, after modifying the TextBox.Text property, the IMultiValueConverter.ConvertBack(...) method is

问题 I am using a datagrid with a combox that should change the grouping field. I am using the following xaml to define the general grouping template : <DataGrid.GroupStyle> <GroupStyle> <GroupStyle.ContainerStyle> <Style TargetType="{x:Type GroupItem}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type GroupItem}"> <Expander> <Expander.Header> <StackPanel Orientation="Horizontal"> <TextBlock Text="NEEDS TO BE BINDED..."/> </StackPanel> </Expander.Header>

The Floor collection represents a series of building floors that are stacked on top of one another. Each
