property bindMethod

This property sets and gets the 'method' attribute of the binding. The default bind method varies depending on the data source and the capabilities of the data source (for example whether or not it is read only, or whether or not it has sufficient means of providing data change notifications to the binding framework). The values can be:

• oneTime - The data flows from the source to the target once upon instantiation of the binding. Subsequent changes to the data do not affect the value of the user interface element.
• oneWay - Data flows only from the source to the target on demand, or when data changes.
• twoWay - Data flows from the source to the target, and can return to the source (bi-directional) on demand or when data changes.

function onSample()
{
    var sourceBox = scene.getBoxById("mySourceBox");
    var box  = scene.getBoxById("myBox");
    if (box && sourceBox)
    {
        var binding = box.getDataBinding("myBinding");
        if (binding)
        {
            binding.elementSource = sourceBox;
            binding.path = "value";
            binding.bindMethod = "twoWay";
            binding.connect();
        }
    }
