Hi,

I need to remove 'Delete button' from form edit page in admin panel - like the one highlited on the picture below:

I have following code (PackageBuilderProductController) but it doesn't work, any ideas how to do it?

class PackageBuilderProduct extends DataObject {
     
    public static $db = array(
		'SortOrder' => 'Int',
        'Title' => 'Varchar(128)',
        'Description' => 'Varchar(255)'
    );
 
    static $has_one = array(
        'PackageBuilderPage' => 'PackageBuilderPage'
    );
	
    static $summary_fields = array(
        'Title' => 'Title',
        'Description' => 'Description'
    );
	
    public function getCMSFields() {

		$fields = parent::getCMSFields();
		
		$fields->removeByName("SortOrder");
		
		$fields->addFieldToTab('Root.Main', new TextField('Title', 'Title'));
		$fields->addFieldToTab('Root.Main', new TextField('Description', 'Description'));
		
		return $fields;
		
    }
	
}

class PackageBuilderProductController extends ModelAdmin {

	public function getEditForm($ID = null, $Fields = null)
	{
		$form = parent::getEditForm($ID, $Fields);
		
		$fields = $form->Fields();
		$fields->removeByName('action_doDelete');
		
		return $fields;
	}
	
}

Thanks, L.

Hi,

OK I've solved it now using just canDelete() function, so the code should look like this:

class PackageBuilderProduct extends DataObject {
     
    public static $db = array(
		'SortOrder' => 'Int',
        'Title' => 'Varchar(128)',
        'Description' => 'Varchar(255)'
    );
 
    static $has_one = array(
        'PackageBuilderPage' => 'PackageBuilderPage'
    );
	
    static $summary_fields = array(
        'Title' => 'Title',
        'Description' => 'Description'
    );
	
    public function getCMSFields() {

		$fields = parent::getCMSFields();
		
		$fields->removeByName("SortOrder");
		
		$fields->addFieldToTab('Root.Main', new TextField('Title', 'Title'));
		$fields->addFieldToTab('Root.Main', new TextField('Description', 'Description'));
		
		return $fields;
		
    }

	public function canDelete($member = null) {
		return false;
	}

}

It really hard to find any info on this matter in the internet, it's easy to find information on how to remove delte button from grid field:

removeComponentsByType('GridFieldDeleteAction')

But delete button will still show up on the edit page, above method allows to remove it, hope this will help some more people in the future.

Thanks, L.
