Hey guys,

Is it possible to display HTML content in $summary_fields?

static $summary_fields = array(
     'Title' => 'Title,
     'myHTMLString' => 'HTML String'
);

public function myHTMLString(){
     return "Lorum ipsum <table><tr><td>Blabla</td></tr></table>";
}

If I do it that way, I get the HTML elements back as string.

Found a solution. Not very nice, but it works for me:

Add "htmlspecialchars_decode" in frameworks/forms/gridfield/GridField.php line 353:

$rowContent .= FormField::create_tag('td', $colAttributes, htmlspecialchars_decode($colContent));

You can use setFieldFormatting (e.g https://github.com/silverstripe/silverstripe-comments/commit/6de470125b4fe2058a59a47a87f83bc89fb27f07) to override formatting for a column value. Perhaps also try adding your custom summary field to the $casting array, I wonder if GridField picks up the objects casting

private static $casting = array(
'MyField' => 'HTMLText'
);

private static $summary_fields = array(
'MyField'
)

Casting only works if you can return a HTML object:

public function Icon(){
    $output = HTMLText::create(); 
    $output ->setValue('<i style="font-size:50px;" class="'.$this->IconCode.'"></i>'); 
    return $output;
  }

  private static $casting = array(
    'Icon' => 'HTMLText'
    );

  private static $summary_fields = array(
    'Icon',
    'Heading',
    'Text'
    );

Sorry to necro this thread, but the tecnique no longer seems to work in SS3.3

#zenmonkey I've just tested this technique in 3.3.1 & it works sweet.
