Answer 1

You need to add together=true to your criteria.
$criteria->together = true;
It'll add join to query. Some information about lazy loading http://www.yiiframework.com/wiki/527/relational-query-lazy-loading-and-eager-loading-with-and-together/

Answer 2

If you want to display company name,just do this in view.Don't change anything in model->search().
array(
'name'=>'Name',
'value'=>$model->company->name //here name is column name in company table.
),

Answer 3

In your gridview code do the following changes.
$this->widget('zii.widgets.grid.CGridView', array(
'id' => 'divisions-grid',
'dataProvider' => $model->search(),
'filter' => $model,
'columns' => array(
array(
'name' => 'companies',//fied from division table which refers to companyId from company table.
'header' => 'Company',
'value' => '$data->company->company_name'
),
'CompanyID',
'DivisionID',
'Name',
array(
'class' => 'CButtonColumn',
),
),
));
And in your model->search()
public function search()
{
$criteria=new CDbCriteria;
$criteria->with ='company';
$criteria->compare('company.company_name', $this->companies, true );
$criteria->compare('DivisionID',$this->DivisionID, true);
$criteria->compare('CompanyID',$this->CompanyID, true);
$criteria->compare('Name',$this->Name,true, true);
return new CActiveDataProvider($this, array(
'criteria'=>$criteria,
));
}
