OnChanged
This callback is fired when the user changes a parameter value in a property page control (for example, by selecting an item from a drop-down list, changing the value in a field, or selecting a check box).
Note that changing the contents of a list box (setting PPGItem.UIItems property) does not trigger an OnChanged callback.
To access the property page from the callback code, use the PPG object.
Custom Properties implemented in a scripting language.

<property_name> is the name specified in the call to PluginRegistrar.RegisterProperty, with any spaces converted to underscores. For example, if you register a property with the name "My Property", the callback function names start with "My_Property".
// Enable/disable a text box based on the state of a check box
function MyProperty_MyCheckbox_OnChanged( )
{
var bFlag = PPG.MyCheckbox.Value;
// If the check box is cleared, disable the text box
if ( bFlag == false )
{
PPG.MyTextBox.ReadOnly = true;
}
else
{
PPG.MyTextBox.ReadOnly = false;
}
PPG.Refresh()
