Placing a BindingExtender onto a component tray automatically extends the set of commands (so-called Designer Verbs) available for other components (controls) in the same container (usually, a form in Windows Forms, or a window in WPF).
The new commands are available in the context menu for each component (when you right-click on the component or control), and also in the property grid for that component (in the Properties window), when the component is selected:
In Windows Forms projects, if you do not see the commands in the Properties window, right-click in the property grid area, and make sure that the “Commands” menu item is checked.
Following designer commands are available:
:
Allows you to select a point (OPC-DA item, property, OPC UA node/attribute) first, and then binds its value to the selected control, for the Read and Subscribe operations. It binds to the default target member of the control.
You can subsequently use the “
” command if you want to modify the target member selection, or other characteristics of the binding.:
Invokes the Binding Collection Editor, allowing you to add, remove, and modify bindings on the selected control.
:
Removes all live bindings currently defined on the selected control.
When repeatedly using any of the “ ” commands, the browsing continues at the recently selected node. This allows for easier binding of multiple components to a set of related nodes.
When repeatedly using any of the “
” commands, the browsing dialog retains its location and size between invocations, making it easy for the user to position it conveniently during the design session.
