If you are showing image in grid list, you should use a virtual column (with editable -> false).

e.g.

$col = array();
$col["title"] = "Logo";
$col["name"] = "logo";
$col["width"] = "80";
$col["align"] = "center";
$col["search"] = false;
$col["sortable"] = false;
$col["export"] = false;
$col["default"] = "<img height=50 src='http://domain.com/images/{custom_image}'>";
$cols[] = $col;

Default setting is editable -> false.

Now when you double click on it, it won't change to textbox and rest function will work as before.

You can refer demos/appearance/image.php for code / demo.

I used this (to upload the article's images in the server):

$col = array();
$col["title"] = "Photo";
$col["name"] = "Foto";
$col["width"] = "20";
$col["editable"] = true;
$col["edittype"] = "file";
$col["upload_dir"] = "foto";
$col["search"] = false;
$col["sortable"] = false;
$col["show"] = array("list"=>true,"edit"=>true,"add"=>true);
$cols[] = $col;

$upload_url = explode("/",$_SERVER["REQUEST_URI"]);
array_pop($upload_url);
$upload_url = implode("/",$upload_url)."/";

$col = array();
$col["title"] = "Photo";
$col["name"] = "xFoto";
$col["dbname"] = "hmr_own_articoli.Foto";
$col["width"] = "18";
$col["editable"] = true;
$col["sortable"] = false;
$col["align"] = "center";
$col["condition"] = array('$row["Foto"] == ""', "<img height=80 src='images/blank.png'>", "<a class='fancybox' href='$upload_url/{Foto}' target='_blank'><img width=100% height=80 src='$upload_url/{Foto}'></a>");
$col["show"] = array("list"=>true,"edit"=>false,"add"=>false);
$col["export"] = false;
$cols[] = $col;

you can upload the image regulary by the add dialog, then you will view the row with the photo and …

you can delete it from edit dialog, but only if you use the standard edit mode (by clicking on edit icon)
If you use the double click in the edit dialog doesnt appear the image path and the delete button but only a text box in which there is the image name

Hello,

Try setting "list"=>false, in Foto column.

$col["name"] = "Foto";
…
$col["show"] = array("list"=>false,"edit"=>true,"add"=>true);
$cols[] = $col;

Also send me issues screenr.com link or screenshot link.

Here is a screencast: http://www.screenr.com/iHmN

Make sure you are passing 3rd argument (edit options) when enabling double click row function.
$g is grid object – new jqgrid().

<script>
var opts = {
'ondblClickRow': function (id) {
jQuery(this).jqGrid('editGridRow', id, <?php echo json_encode_jsfunc($g->options["edit_options"])?>);
}
};
</script>

This is my call:
var opts = {
'ondblClickRow': function (id) {
var rowid = jQuery(this).jqGrid('getGridParam','selrow');
jQuery(this).jqGrid('editGridRow', rowid, <?php echo json_encode_jsfunc($g->options["edit_options"])?>);
}
};
it's same of your.
do you have some other suggestion?

Emailed you working demo.
