I'm new to Silverstripe and need help.
I have created simple dataobject:

class Documents extends DataObject {
	private static $db = array(
		'DocType' => 'Text',
		'ApprovalDate' => 'Date',
		'PublicationDate' => 'Date',
		'DocNumber' => 'Text',
		'DocTitle' => 'Text',
		'KeyWords' => 'Text'
	         );

	private static $has_one = array(
		'Member' => 'Member'

Give me please any idea how to customize my ModelAdmin so, that all users could only view all objects, and only owner (user with ID == MemberID) could edit and delete his objects?
As the result I want to see such picture: [img=" https://yadi.sk/i/o5Nys_szqnPtQ "]
I try to use such code:

if (!(Member::currentUserID() ==  $Value_of_MemberID_Field   )) {
    	$gridfieldConfig->removeComponentsByType('GridFieldDeleteAction')
			->removeComponentsByType('GridFieldEditButton');
		// add a view button
		$gridfieldConfig
				->addComponent(new GridFieldViewButton());
}  

How can I get $Value_of_MemberID_Field in the row of GridField?

It seems to me I have found the solution: http://stackoverflow.com/questions/36616176/silverstripe-model-level-permissions-cancreate-doesnt-work/36622174#36622174
