Ok, i figured it out.
If you need to initially preselect and display a specific column, operator and/or a value in a search dialog…
1. For the default search dialog, simply add the grid option:
postData:{'filters':{'groupOp':'AND/OR','rules':[{'field':'column','op':'operator','data':''}]}},
to the grid definition.
2. For additional search buttons in the nav bar, use:
function setFilterByCustomer(grid){
$(grid+'_toppager_left').append(“”);
$(grid+'_toppager_left input#FilterByCustomer').click( function(){
$(grid).jqGrid('setGridParam',{postData:{'filters':{'groupOp':'AND/OR','rules':[{'field':'column','op':'operator','data':''}]}}});
$(grid).jqGrid ('searchGrid', {options})
});
}
3. Substitute the colored parts with the appropreate info.
.
