'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
    'id',
    'member_id',
    'Location',
    ...
    array(
        'class'=>'CButtonColumn',
        'template'=>'{view}',
    ),
),
)); 

Answer 1

You need to setup a relation to that table, and you can use the relation to reference that field like this:

$data->member->name;

In your transaction model you would place something like:

public function relations() {
        // NOTE: you may need to adjust the relation name and the related
        // class name for the relations automatically generated below.
        return array(
            'member' => array(self::BELONGS_TO, 'Member', 'member_id'),// foreign key
        );
    }

and for grid you would do like:

$this->widget('zii.widgets.grid.CGridView', array(
'id'=>'transaction-grid',
'dataProvider'=>$model->search(),
'filter'=>$model,
'columns'=>array(
    'id',
       array(
            'header' => 'Member',
            'name' => 'member_id',
            'value' => '$data->member->name'
        ),

    'Location',
    ...
    array(
        'class'=>'CButtonColumn',
        'template'=>'{view}',
    ),
),
));
