Q) How to show horizontal scroll bar in grid (when there are many columns) ?

You need to set following params:

$grid["autowidth"] = false;
$grid["responsive"] = false;
$grid["shrinkToFit"] = false; // dont shrink (or extend) to fit in grid width
$grid["width"] = "600";
...
$g->set_options($grid);

For 2.6.2+,

$grid["cmTemplate"]["visible"] = "xs+"; // show all column on small screens
$grid["shrinkToFit"] = false; // enable horizontal scrollbar
...
$g->set_options($grid);

If you dont specify the width property, it will be the sum of all columns width. To make scroll bar visible, the sum of column width must increase window width.

Q) How can i add caption along with icons of add,edit,delete.

You can set it using following config on jqgrid() object. For example:

$grid->navgrid["param"]["addtext"] = "Add Invoice";
$grid->navgrid["param"]["edittext"] = "Edit Invoice";
$grid->navgrid["param"]["deltext"] = "Delete Invoice";
$grid->navgrid["param"]["searchtext"] = "Search";
$grid->navgrid["param"]["refreshtext"] = "Refresh";
$grid->navgrid["param"]["viewtext"] = "View Invoice";

Altenrate, You need to put following additional JS and CSS code. You can change 'Add User' with your desired caption.

<script type="text/javascript">
$.jgrid.nav.addtext = "Add User";
$.jgrid.nav.edittext = "Edit User";
$.jgrid.nav.deltext = "Delete User";
</script>

After adding captions, the alignment got it out, so put this css.

<style type="text/css">
.ui-jqgrid .ui-jqgrid-pager .ui-pg-div
{
    float: left;
    line-height: 18px;
    padding: 2px 2px 2px 0;
    position: relative;
}
</style>

Please do these changes to enable footer summary row.

Step1: Enable footer row in options

$grid["footerrow"] = true;
$g->set_options($grid);

// set onload js event
$e["js_on_load_complete"] = "grid_onload";
$grid->set_events($e);

Step2: Add custom JS code as mentioned. 'list1' is the identifier for grid. In function 'getCol', 2nd param 'field1' is the name of column, which will show the summary data. Valid options for mathoperation (4th param) are - 'sum, 'avg', 'count'.

<script>
function grid_onload()
{
    var grid = $("#list1"),
    sum = grid.jqGrid('getCol', 'field1', false, 'sum');
    grid.jqGrid('footerData','set', {field1: 'Total: '+sum});
}
</script>

If one need to show complete table's total in footer, refer following example.

$g->select_command = "SELECT id,invdate,total,(SELECT sum(total) from invheader) AS table_total FROM invheader";

Define a column with name table_total, and in footer data, use that table_total field.

<script>
function grid_onload()
{
    var grid = $("#list1");
    sum = grid.jqGrid('getCol', 'table_total');
    grid.jqGrid('footerData','set', {total: 'Total: '+sum[0]});
}
</script>

Q) How to maintain vertical scroll position after grid reload?

First you need to get the handler for load complete.

$e["js_on_load_complete"] = "do_onload";
$g->set_events($e);

Then in callback, you can have following code.

<script>
function do_onload()
{
    if (jQuery(window).data('phpgrid_scroll'))
        jQuery('div.ui-jqgrid-bdiv').scrollTop(jQuery(window).data('phpgrid_scroll'));

    jQuery('div.ui-jqgrid-bdiv').scroll(function(){
        jQuery(window).data('phpgrid_scroll',jQuery('div.ui-jqgrid-bdiv').scrollTop());
    });
}
</script>

Q) How to scroll to a particular row value after grid reload?

First you need to get the handler for load complete.

$e["js_on_load_complete"] = "do_onload";
$g->set_events($e);

Then in JS callback, you can have following code. This will iterate all rows and find row with name 'Victoria Ashworth'. It then uses row's first column 'client_id' to get id and focus it with scrollTop().

<script>
function do_onload()
{
    var rows =  $('#list1').getRowData();
    for (var i=0;i<rows.length;i++)
        if (rows[i].name == 'Victoria Ashworth')
        {
            var t = jQuery('tr.jqgrow[id='+rows[i].client_id+']').position().top;
            jQuery('div.ui-jqgrid-bdiv').scrollTop(t);
        }
}
</script>

Q) How to highlight some cell based on row data ?

You can do it onload event of grid. First you need to connect event, and then write your desired logic in JS code.

In Grid config, set event callback.

$e["js_on_load_complete"] = "do_onload";
...
$grid->set_events($e);

In callback function, write your code.

function do_onload()
{
    var grid = $("#list1");
    var ids = grid.jqGrid('getDataIDs');
    for (var i=0;i<ids.length;i++)
    {
        var id=ids[i];
        if (grid.jqGrid('getCell',id,'qty') == '0')
        {
            grid.jqGrid('setCell',id,'price','','not-editable-cell'); // make cell uneditable
            grid.jqGrid('setCell',id,'price','',{'background-color':'lightgray'}); // make bgcolor to gray
        }
    }
}

Q) How to apply formatting of rows, based on 2 or more fields.

You can use a load complete callback handler, and put conditional formatting JS code in it. For instance, refer following example, where list1 is grid id.

// PHP part
$e["js_on_load_complete"] = "do_onload";
...
$grid->set_events($e);

// HTML part
<script>
function do_onload(ids)
{
    if(ids.rows) jQuery.each(ids.rows,function(i){

        // format row when gender is 'male' and company name starts with 'Bl'
        if (this.gender.toLowerCase() == 'male' && this.company.indexOf('Bl') != -1)
        {
            jQuery('#list1 tr.jqgrow:eq('+i+')').css('background','inherit').css({'background-color':'#FBEC88', 'color':'green'});
        }
    });
}
</script>

Q) How to persist selection, data ordering, column order, page number, selection in grid, expand same subgrid on page refresh?

Include following JS plugins files in your page, and add 'opts' setting before 'echo $out' as mentioned below:

<!-- library for persistance storage -->
<script src="//cdn.jsdelivr.net/jstorage/0.1/jstorage.min.js" type="text/javascript"></script>
<script src="//cdn.jsdelivr.net/json2/0.1/json2.min.js" type="text/javascript"></script>
<script src="//cdn.rawgit.com/gridphp/jqGridState/63904a57244ef89fa58ca0fa146da8e2e6e4d395/jqGrid.state.js" type="text/javascript"></script>

<script>
var opts = {
    "stateOptions": {
                storageKey: "gridStateCookie",
                columns: true,
                filters: false,
                selection: true,
                expansion: true,
                pager: true,
                order: true
                }
    };
</script>

<div style="margin:10px">
<?php echo $out?>
</div>

Q) How to keep page number persistence when back button is clicked from new page?

Here we need some JS trick to pick if back button is clicked. When defining URL in column, here we've placed #moved in url and used JS onclick to send to new page.

$col = array();
$col["title"] = "Note";
$col["name"] = "note";
$col["width"] = "50";
$col["editable"] = true; // this column is editable
$col["default"] = "<a href='#moved' onclick=\"location.href='details.php'\">Details</a>"; // render as select
$cols[] = $col;

Enable state persistence of paging, all rest disabled.

var opts_list1 = {
        "stateOptions": {
                    storageKey: "gridState-list1",
                    columns: false, // remember column chooser settings
                    selection: false, // row selection
                    expansion: false, // subgrid expansion
                    filters: false, // filters
                    pager: true, // page number
                    order: false // field ordering
        }
    };

And to open first page if not back is clicked, i will clear state persistance if not hash is found in url.

<body>
    <script>
    jQuery(document).ready(function(){
        if(window.location.hash=="")
        {
            jQuery.jStorage.deleteKey('gridState-list1');
        }
    });
    </script>

    ....

</body>

Q) How to apply more advanced conditional formatting?

You can set onload event in PHP code, and enable 'reloadedit' option

// set js onload event
$e["js_on_load_complete"] = "grid_onload";
$g->set_events($e);

// required to format rows after editing
$opt["reloadedit"] = true;
...
$g->set_options($opt);

Then in HTML code, you can have custom conditional logic in javascript handler. In this code, list1 is grid id. You can also use php's equivalent '$g->id' to reference it.

<script>
function grid_onload(ids)
{
    if(ids.rows)
        jQuery.each(ids.rows,function(i)
        {
            // if col1 = yes and col2 = n/a, format row
            if (this.col1.toLowerCase() == 'yes' && this.col2.toLowerCase() == 'n/a')
            {
                // highlight row
                jQuery('#list1 tr.jqgrow:eq('+i+')').css('background-image','inherit').css({'background-color':'#FBEC88', 'color':'red'});
            }

            // if col3 = 1, format cell. 'aria-describedby=list1_col3' is 'gridid_colname' convention to identify cell.
            if (parseInt(this.col3) == 1)
            {
                // highlight cell
                jQuery('#list1 tr.jqgrow:eq('+i+')').css('background-image','inherit');
                jQuery('#list1 tr.jqgrow:eq('+i+') td[aria-describedby=list1_col3]').css('background','inherit').css({'background-color':'#FBEC88', 'color':'red'});
            }
        });
}
</script>

To make non-editable column as gray, e.g. If 'list1' is grid id and 'name' is non-editable column:

<script>
function grid_onload(ids)
{
    if(ids.rows)
        jQuery.each(ids.rows,function(i)
        {
            // if col3 = 1, format cell. 'aria-describedby=list1_col3' is 'gridid_colname' convention to identify cell.
            if (jQuery("#list1").getColProp("name").editable == false)
            {
                // highlight cell
                jQuery('#list1 tr.jqgrow:eq('+i+')').css('background-image','inherit');
                jQuery('#list1 tr.jqgrow:eq('+i+') td[aria-describedby=list1_name]').css('background','inherit').css({ 'color':'gray'});
            }
        });
}
</script>
