Parameters

Name	Type	Description
`objname`	String	The name of the section.

`expanded`	Boolean	Whether to invoke the callback when the section is expanded or collapsed. If true, the callback is invoked when the user expands a section.

Result	Value
(none)

Example

This example registers a named function to be called when a section is expanded or collapsed:

function customSectionCallback()
{
    if ( IsFieldEmpty( "Problem" ) )
    {
         ShowErrorDiv( true, "A problem entry is required" );
    }
    else
    {
         ShowErrorDiv( false );
    }
}
AddSectionCallback( "ProblemsSection", customSectionCallback, false );

Comments

Callbacks are invoked in the order in which they are added. This callback can be used to perform validation or other data verification. If you want to display a field validation error, call MakeFieldInvalid from this callback so that any required or invalid field errors are automatically processed.
