The binding extender (BindingExtender component) has the ability to extend the properties of existing controls. When a binding extender is in the container (is placed onto the component tray), each eligible control receives new properties. Some of these properties are hidden, the remaining appear under the “Live Binding” category in the Properties window for each extended control.

Windows Forms

In Windows Forms projects, extender properties are usually shown in the Properties window under the Live Binding category:

WPF

WPF design-time features are not available in QuickOPC version 2024.1. This affects the ability to use Visual Studio to configure Live Binding in WPF applications, and to configure properties of QuickOPC WPF controls.

You can still use XAML editing to configure properties of QuickOPC WPF controls. QuickOPC version 2024.1 still fully supports WPF in run-time, i.e. the functionality of QuickOPC WPF controls in run-time is not affected, and also existing applications that use WPF Live Binding run correctly.

We are evaluating the feasibility of supporting the WPF design-time features in a future version.

Similarly to Windows Forms projects, extender properties in WPF are usually shown in the Properties window under the Live Binding category, but a bit differently:

Common Concerns

The BindingBag extender property contains the binding bag, i.e. the collection of live bindings on the control. The designer shows the number of bindings contained in the bag. If they have the same type, it also shows a corresponding icon for that binding type, and if they have the same source, it also shows what the source is.
