Hi,

Only certain edittypes are allowed.
However you can use $col["default"] to specify any html you want in cell, so you can put

$col["default"] = "<button> …. ";

For reference, please check demo > appearence > custom-buttons.php

OK. However, the documentation here (http://www.phpgrid.org/docs/) says…

Render as button
$col["edittype"] = "button";
$col["editoptions"] = array("value"=>'Click Me');

…is the doc incorrect or just incomplete?

I think there is some confusion.

The edittype > button, will show button when the record is in edit mode, and it work with this code, and not in display mode.

$col = array();
$col["title"] = "Button"; // caption of column
$col["name"] = "button";
$col["width"] = "50";
$col["editable"] = true;
$col["edittype"] = "button";
$col["editoptions"] = array("value"=>'Click Me');
$cols[] = $col;

If you wish to display button in display mode (non-edit), you have to use this property.

$col["default"] = "<button> …. ";

For $col["default"], you can refer the demo of custom-button.php

Hello, and what if i want that the

$col["default"] = 'my html code'

shows only when the user doubleclick the field to edit it?

You can set:

$col["editoptions"]["dataInit"] = "function(o){edit_custom(o);}";
$cols[] = $col;

… and in html section, we can define custom edit-type display

<script>
function edit_custom(o)
{
setTimeout(function(){
jQuery(o).replaceWith('my html code');
},100);
}
</script>
