Question

I wanna make a databinding in a custom class. But it seems different from normal databinding.

For example, I have a custom class DisplayInfo with a properties DisplayText(string), DisplayStyle(string) and DisplayDescription(string).

和在另一类习俗中,含有显示Info型的房地产显示器。

例如:

public class ViewUI 
{
    ....
    public DisplayInfo DisplayData { get; set; }
    ....
}

I want to do DataBinding of the DisplayText in the Xaml. How could I do so?

参考:

    <ViewUI .......>

        <ViewUI.DisplayData>
            <DisplayInfo Description="Description 123456...." DisplayStyle="Style123" DisplayText = "{Binding.....}"/> <!-- (How to do databinding here or in other place?) -->
        </ViewUI.DisplayData>


    </ViewUI>

你们必须改变习俗类别中的财产,以改变依赖性。如果贵阶层的财产是依赖性财产,那么你就能够将其捆绑在Xaml。

依赖性财产是什么?

You can enable what would otherwise be a common language runtime (CLR) property to support styling, data binding, inheritance, animations, and default values by implementing it as a dependency property. Dependency properties are properties that are registered with the WPF property system by calling the Register method (or RegisterReadOnly), and that are backed by a DependencyProperty identifier field. Dependency properties can be used only by DependencyObject types, but DependencyObject is quite high in the WPF class hierarchy, so the majority of classes available in WPF can support dependency properties. For more information about dependency properties and some of the terminology and conventions used for describing them in this SDK, see Dependency Properties Overview.
