OnGetCustomColumnGroup

This event allows you to setup multi-row grid header.

 

Signature:

function OnGetCustomColumnGroup(FixedKeysArray $columns, 

                                ViewColumnGroup $columnGroup)

 

Parameters:

$columns

The associative array of column headers.

$columnGroup

The default (root) group. By default all column headers are placed in this group.

$columnGroup->add(new ViewColumnGroup('Common info',

    array(

        $columns['id'],

        $columns['title'],

        $columns['release_date']

    )

));

 

Example 2

This example shows how to define nested column groups:

 

$columnGroup->add(new ViewColumnGroup('Addtional info',

    array(

        new ViewColumnGroup('Texts',

            array(

                $columns['genre_id'],

                $columns['original_title'],

                $columns['original_language_id']

            )

        ),

        new ViewColumnGroup('Numbers',
