I'm using large tables where frequently I'll need to add lots of rows after the table has already been rendered.  This can be slow and running it through a profiler shows that much of the time spent is in the AddRowData -> updatepager call.  This patch allows you to suspend the pager updates during row adds.   (Similar to how Windows GridView and ListView widgets allow the same kind of suspend / restore).

Near line 728 add this default parameter for tables:

                             suspendPager: false,

Near line 2878, change this:

            t.updatepager(true, true);

to this:

            if ( ! t.p.suspendPager ) {

                         t.updatepager(true, true);

            }

And to use:

       jQuery("#mytable").setGridParam({ 'suspendPager': true });

       // Do bulk adds here

       jQuery("#mytable").setGridParam({ 'suspendPager': false });

I hope this gets incorporated into the source, so I don't have to patch each time I update jqGrid.  Smile

Hello,

well this is true.

If you do not know the addRowData can accept a array parameter which contain objects of data row . i.e instead of

for(var i=0; i<adddata.length; i++)

{

    $("#grid").jqGrid('addRowData', rowid, adddata[i], ...);

}

you can simple

$("#grid").jqGrid('addRowData', name_which_is_row_id, adddata, ...);

This will incredable speed the add process ans moreover the update pager is called only once at end of adding.

Best Regards
