jqGrid paging question

If you have 17 records and are displaying 15 at a time then when you're on page 2 you see records 16-17 of 17 - makes sense.

Now when you're on this se开发者_如何学Pythoncond page and you hit the reload button on the nav (set datatype='json') when the grid reloads the nav is showing that the grid is displaying 16-30 of 17. This seems to be a bug - is there a workaround?

The grid still has 17 rows - but it's trying to show a full 15 rows (the rowNum) setting on the second page when it should only be showing two rows (16-17). And the nav pagination text is incorrect (referring to 30 rows when there is only 17).

You are right. It is an old problem. I used always before

$("#list").setGridParam({page:1}).trigger('reloadGrid');

but there is another way. The trigger 'reloadGrid' support additional options: 'current' and 'page'.

$("#list").trigger("reloadGrid", [{page:1}]);

will reset page to 1 in one step. The usage in the form

$("#list").trigger("reloadGrid", [{current:true}]);

allows to preserver current selection. You can of cause combine both options.
