## OnInit

### Description

This callback is fired when a property page is opened (inspected).

Use this callback to initialize a property page. To access the property page, use the PPG object in your OnInit callback.

### Applies To

Custom Properties implemented in a scripting language.

### Syntax

    function <property_name>_OnInit()
    {
            ...
    }

    def <property_name>_OnInit( in_context ):
            ...

    Function <property_name>_OnInit( in_context )
            ...
    End Function

    sub <property_name>_OnInit
    {
            my $in_context = shift;
    }

<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".
