A CNiBindings object is a collection of data binding objects on a button, graph, knob, numeric edit, or slide control. Data binding allows you bind a control property to a data source, such as an item on an OPC or DataSocket Server.

  • Use the Bindings property on the control to obtain this collection.
  • Use the Add function to create additional binding. Add returns a CNiBinding object, which represents the new data binding.
  • Use the Item function to access existing bindings in the collection. This function can access bindings by either name or index.
  • Use the Remove function to remove existing bindings from the collection. This function can access bindings by either name or index.
  • Use the RemoveAll function to remove all bindings from the collection.
