Question

I am using jqgrid advanced search in my project. Everything works fine. Now I have to display a default search condition on click of search button. Please tell me how can I achieve this. I have tried the below code in beforeShowSearch

var postdata = 
                {
                    filters: '{"groupOp":"AND","rules":[' +
                            '{"field":"invdate","op":"gt","data":"2007-09-06"}]}'
                };
                grid.jqGrid('setGridParam', { search: true, postData: postdata });

It dint work.

If you need to reset searching filters on every opening of advanced searching dialog you can’t use beforeShowSearch callback in the case because the postData.filters will be read by searching dialog before calling of beforeShowSearch. What you can do is adding of your custom Searching button with respect of navButtonAdd which looks exactly like the original search button and use search: false option of navGrid to have no standard button. Inside of onClickButton you can reset the filters property of postData before calling of searchGrid.

Alternatively you can reset the value of postData.filters inside of loadComplete callback and use recreateFilter: true option of advanced searching to force creating of new filter on every opening of searching dialog.

The demo demonstrate the last approach. It defines first the variable

var defFilter = '{"groupOp":"AND","rules":[{"field":"invdate","op":"gt","data":"2007-09-06"}]}';

and use loadComplete for resetting the filter

loadComplete: function () {
    $(this).jqGrid("getGridParam", "postData").filters = defFilter;
}
