You can use postData to give parameters which will be appended to the url before the request. To make no request at the page start you can set datatype parameter to 'local' at the beginning. After user click in the "search" button you can change datatype parameter to 'json' and page to 1 with respect of setGridParam() and then call trigger('reloadGrid'). You can set more additional jqGrid parameters on the same way. Before call of  trigger('reloadGrid') you can optionally do some additional work like setting grid title with respect of setCaption('A text') jqGrid method. If you don't want to display jqGrid before the first click of the "search" button you can place jqGrid inside of a div with "display:none;" CSS style and use jQuery function show() to make the div visible if needed.

A code example you find in my answer on stackoverflow:

I need to show the grid after the user has entered some information in a couple (2) textboxes and then clicked a button (search).  The jQuery Grid will display the results of the search.  This is impossible to do though without being able to pass these 2 parameters into the grid so that when it goes to the url 'MSF/DynamicGridData/' along with the sortname, sort order, page, etc., parameters it also passes in the values from my 2 textboxes.

I haven't got a clue how to do this, but it seems that I Grid for displaying data wouldn'e be much good if it didn't take parameters somehow. 

Please help!

Thanks,

Brian
