Question

Is there an easy way to disable paging when searching in a JQGrid?
When a user searches I want to display all of the search results on one page.

Basically I want rowNum: 10000 and the pager disabled but only when a user searches.

Edit: Got this to work with something like:

  beforeRequest: function () {
                            if (jQuery("#ClientPickerGrid").getGridParam('search') == true) {                                 
                                jQuery("#ClientPickerGrid").setGridParam({ rowNum: 10000 })
                            }

The usage of rowNum: -1 is not supported by jqGrid especially if you use local datatype or loadonce: true option. You should use and large enough value like rowNum: 1000 or rowNum: 10000.

UPDATED: The solution can depend on the datatype which you use and on the value of the loadonce parameter. Moreover you can use some events existing in searching. So if you write about searching you should always write which one from the searching you use.

If no other information is known you can use beforeRequest event to test whether search parameter of jqGrid is set to true. In the case you can temporary change the value of rowNum and restore it’s original value in loadComplete. If you send the request to the server (if you use datatype: 'json' or datatype: 'xml') it can be important to change the rows value sent to the server. You can do this inside of serializeGridData event handler. Inside of serializeGridData the search will be seen in the posted data as _search.
