Hello,
I have used this code from the demo
$grid["altRows"] = true;
$grid["altclass"] = "myAltRowClass";
<style>
tr.focus-row
{
background: green;
color: black;
}

tr.focus-out
{
background: lightgrey;
color: black;
}

tr.focus-teal
{
background: teal;
}

.focus-cell
{
background: red;
color: black;
}
</style>
<style>
/* alternate row color */
.myAltRowClass { background-color: #F1F1F1 !important; background-image: none !important; }
/* first row color */
.ui-jqgrid tr.jqgroup, .ui-jqgrid tr.jqgrow { background-color: inherit; background-image:none; }
</style>

It looks fine, but when I focus a row it only work for row that have a white background…
Do you know how to fix this?

Thanks
Cedric
